Markus,
If it is your task to stay with a single amp then all bids about line-level crossover are off. I would like to stress that although there are zillion theoretical and applied reasons to prefer line-level but still it does not mean that regula...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

Fostex T 500A MK 2 Horn Super TweeterArticle By Bill Gaw at www.enjoythemusic.com
As most of you know by now, I'm a horny type of guy. While my wife may dispute this, my audio system (actually my second partner) would have to agree as all seven spea...

In his latest YouTube,Romy mentioned using my prepro to time align my drivers.I use the Trinnov Altitude 16 prepro which has a total of 20 channels. 16 of the channels have balanced analog outputs and the othe four Channels use the rca and optical sp...

Albert, the Adjustable Hydraulic Dampening might be effective if the vibration of floor is the factor. This is exactly what I question as I do not feel that the floor vibration is a problem. Considering the length of the waves and the amplitude of t...

Considering all "cautions" mentioned by Paul and rawuk regarding SET capriciousness to crossover and speakers I am confident that I will NOT have any problems related to the above cautions of crossovers or speaker loads.
I use an active...

There are few more observations I would like to share after listening
my new IB over this weekend.
The midbass. The midbass channel that is handled by a single
Vitavox 15 driver with use of my new IB became if not more propitiate but at

[quote user="MINGSU"]I think most of reader get my point of the car examples. The main point is to follow the manufacture recommendation on how to use the driver. Of course, if you want to do something different, that is your choice but don't come ...

So what was next...They build the DAC, patented the clock... ok.They build their own preamp. Fully descrete class-a balanced, john curl wouldnt do it differently. Nice. Low and adjustable gain - very nice. Constant impedance step attenuator - my favo...

Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...

A horn loaded installation shell not be mono, period! I have observed this phenomenon for years and I insist that it is impossible to make a properly performing horn-loaded playback. I have no explanation for it but I take it a rule: the monoph...

[quote user="Paul S"]I have also been thinking of subbing electrolytics for the huge - up to 100 uF - caps in my speaker level crossovers, just to hear it for myself. Although everyone says to use polys in the signal path, etc., I just wonder a...

Well, Gera, a good question in context of your playback. How a person who has multichannel 106db playback with SS amplification and active crossover to explore SET domain? It is not so simple and if you do then probably it would require bringing ...

[quote user="Paul S"]While you are merely being empirical, there are actually plenty of devices that aim to "benefit" the end sound of SS gain by using tubes to "condition" the signal from DACs, etc. Also, there are plenty of commercial widgets ...

[quote user="decoud"] Romy, can you be persuaded to post a sketch of what you think the optimal 2 channel Melquiades circuit would look like? [/quote]
Decoud, I do not think that there is such a thing as optimal DSET. The entire concept of DSET is a...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

I was listening last night the HF section of MiniMe. It was interesting and frankly very promising. The RAAL 70-20XR were fine and he JBL5 did splendid. They are not properly integrated, were not measured and were made up to work together well, it wa...

Paul I slightly surprised about your comments. The regulating aerial amplifier tube affected sound very mildly, if ever, at least it was my experience. I had a few different 6AK5 but changing them was not a highly notable effect. I still have left a ...
