It is kind of sad day and I think I will take a break for a week or two and will not be playing with my speakers. I begin to integrate the 15-in woofer with Remedius and it was not as simple as appear. I do not think that the location when I have my ...

Hi Romy, It's called "the itch". I was debating high and low before plunging for the Pass. I played around with the capacitance setting. I put it to ZERO and the sound lacked body. 100pf was a little better. Bass was tight but lacked absolute weight....

I do not advocate injector
on the ground. The way how I use my injector I high pass is aggressively, so the
ground coupling is not a requirement. If somebody use injection at lower
octaves then it might be a merit to do so but not in context of my...

[quote user="Paul S"]Romy, no doubt the following derives wholly from my ignorance on the subject, but I have not been able to get away from a sense of "variable compression" with any compression horns I have tried. By "variable compression" I ...

Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may in fact not be co...

[quote user="Kcct82"]On to other things... now that we've been using the GOTO SG505 for a while, the verdict is that it does not sound good below 290hz. [/quote]
As I understand you use the GOTO SG505 in 150Hz horn and report that it does not sound ...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

Hello Macman,Nice horns, I like that you finished everything properly! I am getting tired of seeing piles of horns.I think the ringing you are getting from your midbass horn is that the throat reactance is not balanced. How did you calculate the ba...

I wish I could stop the US government from selling AK47s in any corner shop in the US. If you give a monkey a gun, most probably he will shoot himself. If you give a monkey an AK47, well that is different. He will take anything he wants and few thi...

Well, I decided it was time to start using some "proper" interconnects between the preamp and DSET's, ordered them and had them delivered. To date I had been using cheap interconnects from the local electronic shop (literally $6) which should be ok...

I was keep listening my Dutch-made SA8535 tweeter. There is a lot of deferent with this tweeter and I think it is a good time to pass my early observations about the tweeter Sound.
This driver is not a ribbon tweeter as the Stage Acompany frau...

[quote user="Lx_"] The second sentence is my own conclusion. It was not my intention to imply that it is yours, sorry for the misunderstanding this may have caused. We both agree that PP can be sensitive to incoming AC. The context and circumstan...

I just posted yeastoday the post above and have got already a few emails asking about the “new” ways that I am planning to use S2. OK, let me to explain what is going on.
The default Vitavox S2 driver comes with thier default aluminum diaphragm with...

[quote user="Paul S"] Speakers: I built a version of Dick Olsher's 3-way Diamond Edition BassZilla (hard to find at www.blackdahlia.com), and I tricked it out considerably from his mule. Bass is BR, 15" Audax P380MR, which is a nice semi-...

OK, thanks. I would leave for others to decide what the “higher resolution image” might mean. It might be some kind of untranslatable Japanese folklore. The more vibrant color palette is definably a valid accomplishment, no one knows through if it is...

I do not make any claims just inform about the LessLoss standing. I do not know how much BS in this and HOW they removed the “outer layer” of conductor from the pass but who knows… might be they are up to something… It is said that begin all thos...

OK, it took for a while but at this point I have nailed down all design aspects of the new 6-channels Super Milq, and particularly its input stage. I have listen and evaluated all solutions that will be implemented in there; selected, appraised and o...

Yes you don't want to go over 0 "dBFS" for sure. In fact it is not good to even hit 0 dB from what I have read in an AES paper. Something odd happens when you play it back (I can't remember the details). I shoot for peaks at -2 or -3 dBFS when...

The Rohde & Schwarz EU-6201 tuner was made for German Ultrakurzwellen (ultra short waves or FM) Broadcast Network. The idea was to have a chain of wide-bandwidth composite signal receivers that feed re-transmitters. I made an attempt to accommoda...

First of all we need all to understand that all channels attenuators need only for setting up phase of playback live. When the installations are set up properly then it is all not necessary. Anyhow, if the upperbass has less output then you might use...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

[quote user="Romy the Cat"]Again, it was very interesting, but… Let agree that methodologically you did not try Placette as it performance was masked out by you need to use your Neurochrome buffer to get gain. Your chain will sound as the worst eleme...

This is classical common mode noise interference on a common supply. This type of noise will pass right through any power conversion technology and in both directions. Due to the timing variations, I would expect it to be a little bit of mains inte...

I am using the Celestion Axi-periodic compression driver in the KLIPSCH K402 horn which I have boosted considerably when I noticed that the top one and one-half octaves were barely working when playing music so I figured WHY NOT? and it works just f...

[quote user="Paul
S"]If you said anything about your 15" VitaVox in the video, I
must have missed it. What frequency range are you running them, and what
is low-pass filter? Given your prejudices, I suppose the cabinets are sealed,
so they can't...

I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not t...

I know many would view the two frequencies as similar and perhaps of little consequence, but I have my reasons.My primary, driving objective for wanting the horn to produce sound faithfully to at least 90Hz is that 90Hz represents an ideal crossover ...
