[quote user="Paul S"]You have mentioned that you want a much larger enclosure for your oops unit. I was then wondering if you aim to merely broaden and/or lower resonant response or if you planned to in some way tailor resonance as it rela...

Thanks for this one Romy, very interesting...it sorta ties together several things that I have been thinking about lately. I guess I am lucky that the Bass Cannons can be run off 9w from the DSET bottom channel and from memory I get about 115dB at 1...

After thinking about this for a while, I have had a thought that should be relatively easy for anyone motivated to explore and I would be interested to see what others on this forum observe from such experiments.Fundamentally I think the injection ch...

By the way I was trying to listen Auto 2D. I have no idea why but it is such a despicable garbage. I did all correct configurations. I have exceptionally good result when I play Auro 3D over 2D configuration, using just side channels nothing else, ju...

The injection channel is the only thing about the Macondo that raises my eyebrow as a kind of "out there" concept and I have been meaning to ask about it for quite some time. I tried to brush up and read as much as I could just now on your experience...

[quote user="stevie7V"]… they can be used effectively in parallel with the main speakers and running about 5 or 6 dB quieter. I use them with a separate amplifier and adjust the volume until I 'just can or can't hear them'. At this level,...

[quote user="drdna"] Fundamentally I think the injection channel and layered sound are different things. The injection channel is designed simply to compensate for the timbral shortcomings of a particular driver. However, because of lobin...

Howdy Romy and all. It's a pleasure to visiting the site again, AND again I found myself flabergasted by the words coming out of your mouth Romy! Now dipole bass! What would the cat of 15 years ago say to the cat now?!?I make fun but I too have had g...

As the recordings themselves are missing so much information, creating a plausible image (certainly not the original) is the actual “art” involved.I must admit that I do not generally have issues with singers mouths stretching between the speakers or...

I seem to remember a "Diatone" driver in some sort of "Helmholz" box (or maybe a "double box") that was supposedly developed by the Post War Japan Broadcasting Company, or something like that. Quite slow and "forgiving", but also interesting to...

I am revising the architecture of my playback in context of benefits
of reverberation fields injection. Certainly, Macondo and Melquiades stay as
they are. I always had a pilot system that runs in parallel with Macondo driven
by a cold SS amp. I u...

Well, a few things that I need to note. If you or anybody else are trying to make an impression about own installation and use video then please make a relevant video. The video you made is irrelevant as it shows absolutely nothing. What is the purpo...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

[quote user="AOK_Farmer"] Here's what I've been trying. 8 ohm 4.5 inch full range Omega driver in a 0.35 cu ft sealed box and 6 mH coil 200 Hz electrical crossover. The main speaker is JBL Array 1000. This full range driver has my favorite *tone* of ...

I have to tell you that I would go little obnoxious with my ides of the “Injection Channel” and if I have a change then I would drop the resonant frequency of the box with the Reds. I do not what to commit myself with this project but if someone loca...
|

Yeah, they are my own experiments so I am the only one that need to care. They are based on your earlier work, so I felt like writing and tell you what I am doing with your ideas. The drivers we use may be superior or inferior. As long as mine are t...

[quote user="Paul S"]So, separate wipers only for injection and HF, or are there other means to adjust relative levels amongst/between all channels?[/quote] The Injection, HF, and Fundamental (via speaker level LPAD) are the only channels that need a...

So, the first DSET is still downstairs on the electronics bench and I am back to work for a while, but not too hard and not for too long (I hope). I've added all the filters and checked and tested and changed some more things and decided that it was...

Any playback, unless it is an idiotic yellow driver speaker, bet bigger with sound become bassier. I however, very seldomly use phrase “subs” as it does not define what it is. The idea to have width modulation channels did come to me and I did a few ...

Ok, the Injection Channel project is over. I dumped the boxes not heavily and very conventionally, painted them, installed the drivers and crossovers. Sure, before I put the injection channels into the Macondo frame I flipped them upside down and tri...

I long suppposed the whole thing hinged on a sort of dither effect, like the PurePower thingee. And I think this is at least some of what happens with "injection channels", including the root concept of what we are actually discussing in this thread...

Pretty clean, Romy (and one hellova tranny at Fundamentals)!Of course, I have questions:I thought you said Vishay metal foils in your earlier response about bias adjustment?If so does that mean steps, or... how, exactly?When you specify "Full" ...

Thank, Paul, interesting links. What is necessary here is to do some critical listening with the idea proposed above. It would not e any measurements but just subjective listening. I am not a huge to of do it on line level and I think the speaker le...

Thanks for sharing, Romy! "Micro" and "macro" "schematics" would be a nice adjunct, to show how you hook up electronics and speakers, as well as speaker positioning. Of course, lots of recordings are treated with synthetic reverb, so those are gettin...

That was funny.Now your here, why not do it right and use a loudspeaker with 5 hz response for injection. it would help to integrate your infinite baffle to the rest of Macondo. One doesn't need the tone of vintage drivers, use cheap modern stuff wit...

[quote user="morricab"]…. putting the attenuator AFTER the gain stage has negative consequences for the sound….[/quote]
Well, yes and no. In the new 6 channels version of Super Milq I will be use 2 stepped attenuators: for Injection Channel and for ...

I'm looking to internally wire to binding posts on exterior of box from woofers in a sealed cabinet. I was wondering what are some options for wiring that will not be a hinder. Would a heavy gauge copper 6nine's copper be sufficient? I'm using so...
