Maybe you remember, even though I liked sealed enclosures I chose the ported bass boxes for my system. The reason was the TAD 1601b's in my situation. They just work and sound better with ported enclosures as they were designed to be used that way.Ma...

Hi all, I have a t350 horn that I recently got out of an old cabinet at a junk shop which does not work. If I connect it to my Marantz 1030 amp it will only play very faintly as if you are listening to cheap earphones laying on...

Romy, Now you mention the issues here, I am thinking about what the differences in quality might be due to. I notice that you haven't explicitly said which is better, super or regular... so think of this just as brainstorming as to why things are... ...

Well, you see, the outer dimensions of the mouth of cause an indications of low end response and by objective evaluation of it is easy to estimate horn’s bass numbers. However, it is very far from “sufficient” assessment. A few years back I completel...

Yes, the Dresden’s talk about 40Hz horn and 90Hz horn as the similar horns, particularly if he does not want to "cheat", stroked me as odd too. 90Hz horn is a nice a manageable 40” piece of furniture. The 40Hz is the monster in a house and a good rea...

[quote user="Romy the Cat"] I do some very interesting experiments with Rohde & Schwarz tuner. Dima and I have discovered a way to use the Schwarz without the wide bandwidth amplifier, driving the Multiplex Decoder from the Schwarz’s preamps. Bas...

Hi Saturntube, 40 Hz - 200Hz = wooo, woo, wo, - hm... Forgive me as I'm not talking about horns right now, but some sort of 4th order *acoustic* roll-off at 200Hz may apply with a horn as it would, e.g. with a second order cross-over in a box-spe...

I already have some PY500 (it's a sign =))) ) and I have 836 too.I read about Malquiade amplifier threads.So it seem peoples on this forum like horn speakers (I love them too) and are looking for fast transient response, it's exactly what I like.But ...

[quote user="N-set"]just a minor tech remark (feel free to ignore): the big-ass elco is theoretically still well in the picture. 10uF will have 320Ohm@500Hz, which is a fraction of 20Ohm R+3mF elco.[/quote]Jk, actually it is not exactly accurate.

So, looking at the schematic below......I have a few more questions25 turn pot in the filament supply. For the life of me I can't source a 25 turn pot. The 10 turn Bourns 3590 is the closest I can find. Do I need to keep looking for a more sensiti...

truth to be told, i'm so far from building a horn for S3 that the plans may change. the drivers actually haven't left a previous owner yet which makes me a bit nervous. but i understand you presume a short opening horn like expo would allow a more me...

This is our first offering; we are indeed working on another two higher priced models. One will have an additional channel on top, the other one will be front horn loaded down to 40 hz. Optional finish and colors, both for horns and supports, a...

You might want to try covering a section of plywood with the modified cement/mortar recipe as a test before you write it off as too difficult or too expensive. Basically, it does pretty much what you ask, and it need not be 2" thick, either; 1/2" or...

Being a musician, I deal with constructive resonance every day. Tubes resonate as a function of length, boxes resonate as a function of the internal length, width, diagonals. Irregular shapes resonate as a function of volume, horns resonate as a func...

Hello Dan,Love how you pass that cable through the port, I used to do that too...long time ago.Why are you crossing your 250hz horn all the way up to 1 khz?The 2445 should be able to go much lower. Have you measured the response you are getting from...

[quote user="anthony"]My RAAL Lazy Ribbon has ended up needing a 1st order high pass filter to match the midrange S2 which is so much more convenient than third or fourth order as initially intended.[/quote]
In my case I found that RAAL ribbon wit...

I've played around with a couple of amplifiers that have variable output impedance, namely the Berning ZH-270 and Wolcott Presence P220M. The Wolcott Presence in particular is interesting, as the constantly-variable output impedance control can...

What is the difference in audio? You spend day of you live in your listening rooms trying to make that cable elevator between your phonostage and cartridge to “sound better” and someone after listening your setup inform y...

Oh, yes this is the whole idea of Remedies, it is not only a Red combination but it is an assembly with midbass channel which would make it a conventional box loudspeaker. You see, with all interesting things about Tannoy Red the woofer part of t...

Ah, I think I have found the secrets that I was looking for. I still do not work with 15-in woofer but still try to make my red driver sound the way how I want and I got some revelation and the result that is very close where I would like to be. The...

[quote user="Romy the Cat"] I have to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I ...

As I read that darkmoebius wants the amps for a vintage dream "never-built" Olsen cornerhorn I have to ask myself if Melquiades is the first choice for his project. For one thing, do I remember correctly that you eschewed feedbac...

[quote user="Romy the Cat"]I bought the Lundahl chokes for L1 and was not able to us them and they were insultingly sharp. For the L1 you would need more henries and more DCR, the higher DCR will sound better and the “bad” and “cheap” Hammond chokes ...

I can contact them again and ask for a price quote for the SLC. These people don't do audio at all. When I contacted them for my RE-1009/2T they couldn't understand how it was possible that any audio equipment could take any profit of their products....

OK, Guys.
I have sent the “winner’s CDs” to you. I do not remember to whom but for some of the Brits I put 2 CDs. So, who get the second CD then, please, pass a copy to Thorsten Loesch.
I hope you enjoy the Music and thanks for visiting on my site....

Alex, contrary to the numerous speculation that many people more or less reasonably spread about the subject, my experience indicates that there are no such a things as “preferable crossover frequencies". The chosen optimum crossover frequencies are...

Ok, how to start. First of all we have to understand that out subject of attention will be a region between approximately 80Hz and 500Hz or something that shape the fundamentals of the “melody range” within your playback. Search my site I have writte...
