Dealing this new bright PP2000 I was recalibrating Macondo and once again I got a phenomenal demonstration of the power of a Fundamental Channel. Here is a short instruction of how to get THERE...You setup your Fundamental Channel with your crossover...

I had today the “fundamental channel” plug in and was trying to listen it. As usually I do, I connected juts one single crossovered “fundamental channel” to a single amp and try to live with it for a while. It usually takes for me a week or so to fig...

Is that the same as the melody range? Defined per this discussion:http://www.goodsoundclub.com/Forums/ShowPost.aspx?postID=1421#1421Where is the fundamental range in relation to the melody range? Low C is 128 Hz. and it seems to me low C is in the me...

Eventually I found hot to balance out the fundamental channel’s arm a 1 galloon bucket filed with led shot and Super Melquiades power supply do a good contra-mass.
I did not do a lot of listening but the very initial listing that I did are clear...

...Or plug all but the desired LF exit path? This might not have the same compression ratio a stock though. Well, I am still learning about how phase plugs operate.Neil...

Did today some critical listing. It is getting along very well. I would need some final adjustments of channels sensitivity (or tine the 6C33C) and will wrap it up. I will post some general observations later on but for now there...

I set two multicells with LF-enabled S3 drivers. I set them on the outer side of Macondo MF. Playing with crossover, volume and towing of the multicells I was able to a degree to get the effect that would like to get. The pointing the multicell...

R,
Little suggestion should all else fail - you could have a rudimentary phase plug machined that would give you the same (or similar) compression ratio as the original but only one annular exit path. This might preserve the driver characteristics a...

Got today the parts and finalized the “perfect” Bessel passive crossover for my new channel. The coils are regular air-core 2.5H and 7H, the caps are Theta 10uF and the small wirewound tuning resistors that kills ~1.5dB in the channel. When I pu...

Yes. I’m exiting to see how the new horn I shaping up. Still I do not think that it is about second orders. Obviously in context of 5 channels system, the more channels one gets then less room between them. I still feel...

Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...

Above the Johan Dreyer from South Africa uses a sort of Fundamental Channel for his installation. He obviously lucking one more channel to integrate his LS section and the Fundamental Channel. His Lower Mid charnel should be twice larges and sit on...

I picked recently a pair of S3 drivers. Not that I need them but it was good deal – perhaps someone in UK have demolished an old movie theater and a large school of S3 drivers with original diaphragms hit the maket recently. Also, I always meant to t...

Ok, I found my RTA cable and did some very basic measurements of what Macondo does in the room. The results were in the direction that I anticipated but worth in amplitude. My right bass channel that that sited right next to the equipment bay has no ...

After many hours and much efforts I have connected the new 6-channels Super Milq to my 6-channels Macondo, with omission of tweeters for now. I made some measurements and initial adjustments and then was trying to listen it briefly. I did not l...

I did not expect that it would be so much work with the new “fundamental channel”. The new 250Hz horns required some help to correct some problems, plus they have to be finished in a civilized fashion and color. However, the biggest problem is positi...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

First off, I forgot to mention an interesting observation: Before running the sweeps (previous post), since the drivers in the upper-bass horns are new, I decided to verify/optimize rear chamber volume (they are easily adjustable)... I wasn't expecti...

Thanks, Jessie. I just will buy that Beswick Engineering valve, it looks like it is the right size and it look like it will do what I need
I made some experiments applying large gaskets to cover of the back chamber. I used a gaskets up to 12 mm but ...

My 18-cell is a classic 18-cell very similar of the one that the guy from Sweden built:

The difference is that my multicell has 3 extra cells and out...
