The baby passive radiator.

Hey, look what I found: 3’5” passive radiator with 30Hz own primary resonance! That is what doctor ordered!

Not to mention that this beauty costs $12!

Is that Michael J's doctor?
fiogf49gjkf0d
If the reason for the passive radiator is that you want to stop interaction between Macondo and MiniMe, I fail to see the sense. The passive radiator is a replacement for the port. If the port causes you problems, so will the passive radiator, assuming it is the resonance of the port that bothers you and not some other phenomenon (which I assume  to be the case since your are talking about the Helmholtz resonance).

Of course, if you could find a passive radiator whose membrane could be parked in a fixed position when the speaker is not in use, that might help things.

Will see how it goes…
fiogf49gjkf0d
Markus, I do not know if you are right. I think to pay $12 for the passive radiators and to try might be one way to confirm it. I will have them in a few days. My rational (perhaps mistaken) why I feel that it might work and you might be wrong is following:

What triggers the Helmholtz resonator – pressure itself or change of pressure? If pressure itself then you are right – a port or passive radiator would ideals pick up the pressure from Macondo’s LF. However, I think that it is not pressure itself but the rate of pressure change. Let take an empty bottle and blow air across the bottle hole. You will have the classic Helmholtz resonance. Now let to cover the hole with very fine fabric and the resonance will be changed very dramatically.

So, my presumption is that a passive radiator might (or might not) be as some kind of valve that would distinct external pressure flow from internals pressure flow. Well at least it what I hope… It might juts minimized the effect and it might be good enough. The $12 is not too much price to pay to try….

Not quite analogous
fiogf49gjkf0d
Th fabric adds resistance to the tuning, so the tuning of your bottle changes. And if that's the effect you're seeking, I fail to see how the passive radiator will achieve that. You could introduce some resistance in your port, but that would again change the port tuning.

Anyway, I agree that sometimes one just has to try things and see where they take you.

What I mean is not sucks but rather socks, actually it both of them!

I got the passive radiators yesterday. They are very good and perfectly cover my MiniMe ports. The MiniMe with passive radiators is immune to Macondo sound and this is very good news. The said news that MiniMe with those passive radiators has much less bass extension, sure the bass is better quality but better quality bass is not exactly my objectives with MiniMe. So, I concluded that that for now will not be using the passive radiators but keep using the socks with wish I will plug the MiniMe ports when I would like to get the full quietly of the Macondo’s bass.

I might educate myself in future how to calculate and to tune speakers with passive radiators but for now I will leave it as is. I would like to get my new MiniMe amplifier and to see what will happen with bass. I have a feeling that the major problem with all of it that I have a power amp that does not do right bass to begin with… I just wish that I had my Lamm M1.1, that baby would set the things straight….

After some consideration I picked today Yamaha B-2 amp. It is V-FET from 1978, it might be interesting. Post Vince’s site or his shop info I might need to have B-2 serviced or modified. I think the 140W of B-2 might be good for my MiniMe, I just a bit afraid that it might run to hot…
I got today the Yamaha B2, V-FET amp. The amps always new, very cool amp. The sound? I did not believe what I heard – it was probably the worst sound I never heard in my room. The MiniMe was not taking stars from sky but it was very nice balanced system with shitty boring bass but still listenable. With Yamaha B2 the MiniMe sounded beyond any acceptable level of decency. The whole bass section now reminds a sound of a hyena that is being raped or being run over by an asphalt roller. I have no idea where it comes from. Ether the Yamaha B2 is just a crap amps or it is VERY good amp and what I hear is the realty how the MiniMe’s bass section sound with good amplification.

All Warmed Up and Ready to Go?
fiogf49gjkf0d
Romy, I know you know, but just checking to be sure that the B2 has been run for quite a while before evaluating sound.

The "period" of that amp was right around the time that many of the best amps started having ridiculous warm-up protocol, to the point of leaving them on for a week to start and then just leaving them on.

Not saying the B-2 will  ever be worth a crap, but just advising patience with burn-in.

Best regards,
Paul S

The howly sound of Yamaha B-2
fiogf49gjkf0d
Well, I think my Yamaha B-2 is not working well. It slightly cures my ego with MiniMe. I took today the B-2 and drive them with good conventional loudspeakers and it had the same sound –very very howly (and ugly!!!) sound under 200Hz… I wonder, do I need to fix it or is it how the “celebrated” amp must sound?

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams.  I have never heard either amp, anyway.

I have heard a couple of the original Sony Esprit V-FET amps, however, and they were certainly not "howly".

Maybe the thing would never be your particular cup of tea, but also hard to imagine that amp is healthy if it sounds all that bad.

It is fairly old, right?

You have gone over it electrically, right, cleaned contacts, tube sockets, checked parts values, etc., etc.?

Does Yamaha B2 worth a new thread?
fiogf49gjkf0d

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams.  I have never heard either amp, anyway.

Yamaha B1 and B2 conceptually the same amp. B1 is made only with one polarity V-FETs and B2 with complementary plus and minus V-FETs. B1 has more power and does not have the sexy meter of B2. I have no idea how different the in sound. My B2 is virtually new but 30 years old. The signal switches practically do not work and need to be replaced. I did not open it, have no manual or circuitry. The guy who sold me the amp forgot to put any papers in the box and he will ship it to me next week. I use it as it is. I do not know if I will keep it.  I like the idea but it shall show some sound that I might find at least promising. The upper rage of the amp is fine but the bottom is desisted.  I do not know if it is how it shall be.

If I keep the amp and find why I skew up the whole bottom then I will start a new thread.

Not sure if Yamaha merits new thread...
fiogf49gjkf0d
Hi Romy,

Given the Yamaha's age, I am not surprised it sounds terrible.  Someone needs to go through old caps, lousy transistors and cracked solder joints.  

After service, it should be close to or better than new specs; it might not sound very good, but then you can blame the Yamaha engineers and not mother nature and father time...

Bass behaviour of power amps
fiogf49gjkf0d
Recently a German hifi magazine started measuring bass responses of power amps under load. Unfortunately I only had a short glance into the article at a railway station book store, so I don´t remember what exactly they did, but the winner in the 5K integrated amp class was a Brinkman amp without feedback in the last stage. So one really needn´t think if the amp has plenty damping factor one has to blame the speakers.

That is a nifty looking amp; it will be interesting to see how it works with the MiniMe and how well it heats your room this summer

These guys are not Goodwin's but are an old school stereo shop that sells and refurbs 70s/80s solid state gear.  There is no showroom or salesmen, just a few work benches and gear stacked to the ceiling, somewhat like Ken Bernanky's shop, although slightly neater and slightly faster 

Vince is an electrical engineer who has done some rather complicated refurb work for me, and did a good job; he worked for APT Holman and Scott in the 70s and I think is still there in some form, which is ideal for this task in my view.  Give the guy a few minutes to explain all your service alternatives as his suggestions are not always intuitive

Scooter,

I met today Vince Naeve from Audio Pros. To make the long story short I run away from it as I was literally too scared – wish is not so easy to do. The official version was that expressed by Vince: “I am too smart for you”  but the real reason was that this guy is literally dungarees and I was physically afraid to have my equipment in there without adult supervision. Seeing what they do and herring what Vince was saying I literally did not allow him to touch anything! I think he is clearly diagnosable.

Hi Romy,

Sorry about that.  Vince has good days and bad days; sometimes he just does not get it and you did correct by running out.  Given his background in 80s solid state amps and your interesting piece of gear I thought he would have been quite motivated to provide you some creative solutions, rather than to (unsuccessfully) insult your intelligence.  Apologies for any inconvenience once again.  

Maybe Ken Bernanky is next stop.

There is nothing to be sorry. I do not make judgment about his good or bad days. Vince’s inability to focus and too keep his attraction on one subject more than 10 seconds is not what bothered me. He might be motivated to provide “creative” solutions but sorry to say it he was absolutely ignorant what he was saying. 90% of time he spent to convince me that he is a geniuses bit this is a common illness among those people…

I approached Vince with idea to let him to service my B2 but was enthusiastic that Vince informed me that he alight the tuners and that he is the “best I ever seen”. Sure! I stopped by today at his place with my Rohde & Schwarzes, asking him just to diagnose it and to give me a feedback what he sees. I was staying behind him and seeing what he is doing and what he was saying my heart was trembling.

He hit the tuner with his hand!!! He told me some absolutely idiotic stories about Rohde & Schwarz then admitting the he never dealt or even heard the R&S before. He informed me that he needs to replace electrolytic capacitors in frond end of my tuner! The electrolytic capacitors in frond end!!! He opened the cover and be quite violently touched the front-end. I was so closed to ask his do not touch my tuner anymore!

He did not have sweep generator in fact he does not use it for the tuners alignment. He blew the R&S with FM signal, looks at the scope the composite output and he said that it is all that he need to align tuners. I did not believe what I was hearing – he is completely clueless what he was saying. The fact that my R&S picked his 100Mhz signal at 99.95Mhz and his generator was not properly calibrated (he admitted it) seemed did not bother him. I was ready to walk but then he proposed to get more sensitivity. I mean to get right now while I was weighing. It was too good to be true and I informed him that I have 3 technicians (very good technicians) who were not able to work on R&S as they found it design too intimidating for ad-hog tuning. It did not stop his and the master started his “magic”.

The Moron, without looking at the schematics that I had with me took a screwdriver and begin to turn the adjustable pots and coil, trying to see on the scope (!) higher amplitude of output signal. I immediately asked him do not do anything else with the tuner. I pointed him at the pots and the coils that he had touched and asked him if he know what they are or at least in what stage they are located. He had no idea where they were but the mothefaker already trying to turn them!!! I give him a circuit and was suspecting that he we will try to find out what he turned but he begin to ma11ke superbly superficial comments about the circuit from which I concluded the he just did not understand what he was talking about or is accustomed that his customers have no idea what they are getting and how it was done.

He might be a great technician of his mind but he is well underqualified to serve my equipment and he serially shall not touch any RF equipment. Perhaps if I have a broken electronic alarm clock than I might give it to him, with anything ease I would not be risking. He has no knowledge, obvious the experience or mental qualification to serve audio at the level I demand.

Gut wrenching...

Ufffff! For some reason I have never brought anything but old japanese amps to him, maybe it was a subliminal response or intuition based on his personality or the stuff stacked in the store (just old japanese stuff) or just luck. Regardless, his work came out correct.  But after your experience I will not be visiting him again

...that R&S story was absolutely gut wrenching.  I am glad that you and the gear made it out alive

The “nicer” MiniMe, eventually.
fiogf49gjkf0d

Playing with B-2 power amp I made an experiment and instead of loading to it the MiniMe Bass section I loaded the B-2 with Macondo’s bass arrays. I made add-hog attenuator and coil to EQ MiniMe MF with Macondo’s bass and gave some listening. It was nice but not the niceness of that result was something that very impressed me.

What very impressed me was the fact that I was such an idiot and absolutely voluntary deceived myself for a year. I am taking about the MiniMe Bass. I admit that I never meant to get MiniMe sound to any level of seriousness but playing the very same MiniMe with full-blow Macondo bass I suddenly realized that it turned out to vey very nice speaker if I do not use my MiniMe bass section. This little ported (and now with passive radiator) array that I built specifically for MiniMe coast me a lot of efforts and blood and the result might be conceded OK but in a wider scale of the suppressed ego the MiniMe bass  sounds like shit. I kind of accepted this shit as “it was just MiniMe” but using Macondo bass clearly showed that it not suppose to be this way.

The MiniMe bass, with it very sexy G10 enclosure is remarkably comfortable in my view. It is a thin column with 4 X 5” drivers.  One might argue that I am largely ignorant about ports and how to make them to sound “better”. I would not deny it, when those I did played with MiniMe’s post. The best I was able to get was still way out where I would consider is acceptable. Perhabs I used bad drivers or perhaps I have an native hypersensitivity to ported sound (particularly badly implemented) but a few bars of MiniMe placing supported by Macondo sealed bass made me to do the final action.

So, I kicked out the MiniMe original bass arrays out of my room. As a replacement I brought from my storage my old little seals enclosure with a single Scan-speak 21W/8555-00 driver. The 21W/8555 is a little brother of my bellowed 25W/8565-00. (I use 12 x 25W/8565-00 in Macondo array). The 21W/8555 is just 8”, has SD1 motor, magnificent paper cone with very particular Scan-speak suspension (that is hard to call rubber, even it is rubber) and has 20Hz resonance frequency.  The 21W/8555 has the same feeling as 10” 25W /8555 and I am known to be big sucker for those drivers. I do not have a big box for 21W/8555, probably it is 2-3 gallons – 4-6 times less then I would like to have, but it is what it is. So, I brought it from storage and connected it to MiniMe’s MF channel.  That was very nice. The MiniMe’s Utopia TN51 tweeter (that has became the hart of MiniMe) was bit more sensitive but I did calmed it down. The MiniMe’s MF driver is around the 21W/8555 sensitive so it is all nicely balanced. The 21W/8555 bass in the very small enclosure sound a bit “confined” and a bit too fast to my tasted but not frustrating sounding.

I made some test with B-2 driving the new MiniMe arrangement. I took under conservation the changed the MiniMe bass impedance and slightly re-biased the B-2 amps. Now I run it at 75mA and believe or not but loaded to the actual MiniMe I got a first clip at 190W! Considering that I run B-2 behind a voltage deviser that killed 12dB of gain you might understand that I have tremendous amount of power reserved.

With the sealed 21W/8555 bass my respect to MiniMe has revised. I also very pleased how the updated Yamaha B-2 behaves driving MiniMe. It truly has no typical SS nastiness and in fact it sounds much moderated and balance d– it turned out to be a very cool configuration.

Looking behind I have to note that whatever was my initial idea of MiniMe was completely failures. The G10 custom enclosure, the RAAL tweeter and JBL MF driver and 4x5” miniature line- array driver by a cool-running chip amp: nothing is used now and everything go to the storage to join the rest of my failed projects. I would not claim that the MiniMe that I ended up to be has too successful sound but I do like and accept what it is and… that already not too little.

The MiniMe revived, Sound and the Lessons
fiogf49gjkf0d

Ok, I have 200 posts in this thread. I was stated over a year back. Thanks for anyone consulted me and observed where my Pilot Acoustic Systems took me.  At this point, when the MiniMe result has settled to my satisfaction and when I am not going to change anything with my Pilot Systems MiniMe (because I like what it does) I would like to take a sober view to Sound that MiniMe offers, not even to the sound itself bun to the lessons the MiniMe teaches. The lessons are enumerated without any particular order, just as they came to my head. Despite that MiniMe is not serious speaker but the MiniMe lessons are no so laughable.

1)      Do you remember that ‘Romy the Cat’ have always insisted that in ANY playback the LF source must be outside the horizontal plane of MF source? Oh, boy - he was very much right! Playing with HF sound fields coming from the low-pass slope of bass channels it is possible to write amassing tricks into the presentation of sound.

2)      Glory to the mighty Utopia TN51 tweeter! It is not perfect tweeter but in dynamics it beats anything out there. The stinky MiniMe with around sub 89dB sensitively holds its own very confidently in perception of dynamic against 109dB sensitive Macondo. Switching between the Macondo and the Macondo’s pilot there is no annoying dynamic drops.

3)      Fuck the ports under 100Hz of they have resonance lover then the driver resonance. Again.

4)      Only infinite/sealed baffle can develop bass at low dynamic levels

5)      If your loudspeaker has no dedicated upperbass cheval then you have crappy upperbass where the noise from the MF and midbass just smog out the “primary frequencies”.

6)      If you do not do anything special with speaker's tone then your speaker has no tone.

7)      Bass time-misalignment might be very effectively used as “pressure front” generator.

8)      The  “single worst” thing in today’s acoustic systems that I described in here:

…is the single worst. The MiniMe use it to a full extend to substitute natural dynamic with UFH responses that give a feeling of “fake loudness”.  From this stand point MiniMe is not different from most of today loudspeaker and it has very much similar to Magico/Kharma type of sound.

9)      When a speaker is shifty all together but properly balance by “hearing” then it does not sound annoying

10)   No half-ass speakers can play symphonic music at a level of serious demands

11)   The small speakers are fun.

Anyhow, the MiniMe is a freak of nature is away. After my monumental failure with anything that I initially scoped for MiniMe the recent revision of MiniMe was made not my intellect but by intuition – it is like cooking a soup, adding the ingredients into water, tasting it and to go with the flow of whatever is needed. Surprisingly I did not make any single measurement of recent MiniMe – probably I need to do it. It sound file as is, however.

The bigger picture – where is MiniMe in the scale of the absolute results? Well, trust me it is deep in ass and if you invite me in your home and demonstrate the MiniMe-type sound then I would consider the tripe as a waste of my time, unless you feed me. The MiniMe TTH characteristic is garbage and if you ask me to criticize it then you would hear a lot of crude adjectives. Still, I am pleased with the recent MiniMe. The MiniMe is not a standalone solution but rather Macondo Pilot System and listing Macondo and then switch sound to MiniMe one might understand what I was as trying to accomplish. The MiniMe is a way a Macondo’s dildo and does what is meant to do. To my surprise and satisfaction the have similar sound (by natural and surrogate means) and it feels that I do not have two acoustic systems in my room. THAT was the very initial goal and that what it does very well in my view.
