I am finishing us to setup my listening room and I have my PP2000 blowing up sometimes (go to protection bypass mode) when I use powerful SS amp for ULF along with Melquiades and the rest of the systems driver from one single PP2000. So, I guess I wo...

[quote user="decoud"]So the ambition is low, and I am after a simple solution prioritizing these things, but the question of general interest is whether anyone has found an elegant way of turning the constraints of space into a virtue [/quote] We...

I just found this thread and can comment on the Enabled DX4s. Limono (Wojtek) very gratiously loaned his Enabled 8 ohm Lowther DX4 drivers to me this past summer (summer of 2008). It took my a while to make the crossover for these (I have...

Last week I spent a few hours at the scene of NY’s Stereophile Show – HE 2004: a half-day on Thursday and 2 hours on Friday. As many other audio-shows it had many semi-ugly colorations, however as any audio shows this zoo trip brought it’s own “inter...

Romy,I merely thought that you felt I was riding roughshod over your advice, when it was in fact a degree of naivety requiring extensive clarification that may have made it appear thus. Regardless of your indifference to praise and/or criticism, I'd ...

[quote user="Romy the Cat"]since I know that you do not deal with horns and discuss it only as theoretical exercise I am not sure what we are talking about. [/quote]Hahaha :-) This experiment was made a few days ago by a friend of mine who is speaker...

[quote user="Romy the Cat"]I am not familiar with those types of drivers and with the results they are able to show. [/quote]

I did not order the UnipheyeMusic. Tne only recording I was interested was the Beethoven quartet but I did not like how it was recorded. According to the UnipheyeMusic guy the artists were too “famous” to give him a lot of time for recording an...

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...

Mani, BTW, if Silbatone-pimping Joe Roberts showed up in here then it had to be the Aporia speakers with the back-loaded single Manger were presented in the show. Why would Silbatone otherwise to drag to the show that big and expensive mastodon...

A Greek company Arcadian Audio come up with own new horn-loaded loudspeaker.
http://www.arcadianaudio.com/description_style.html

Anyhow, the Arcadian Au...

[quote user="Romy the Cat"]I do not disagree with
it but I would certainly question the practicality of it alone with
cost/benefit ratio. I think if the identically amount of effort would be spend
for other aspects then the benefits would be highe...

With Ming permission I post a fragment of his emails where he describes his midbass horn. It appears that he uses cone-drivers with ltooooooo ow Fz in non-compression application with no back chamber. Now it is obvious where he is losing his midbass ...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

[quote user="Cosmos"] Anyway, as the description on our site on second paragraph says, the third 6C33 located at the back, is used as the pass element of the regulator (controlled by solid state circuitry) providing 220V with 100uV of random noise &a...

It sounds like a lot of the circling has to do with which 2A3 "sounds better", outright. In any case, I'm guessing everyone would agree that it is specious to argue about which 2A3 sounds most like some internally-estab...

As I said before, in many if not all instances the provisions for “bad electricity” are deeply entrenched into the design of our playbacks. A few days back I took advantages of some new possibilities that PP2000 offered and made some changes in playb...

It is complicated. Any tweeter is different and the RAAL’s “Water Drop” tweeter is more different then others. Almond any other tweeters that I heard this tweeter has something absolutely unique- it has no annoying upper MF nose. When I asked Alex to...

I double checked and everything seems connected ok. all parts values are correct. I have measured the voltage across R2 and it was 208V so 208v / 15k = 13.86mA. I connected 1r resistor between M and R2 and it was 14mA. also connected 1r resistor betw...

Haralanov,
What you are experiencing in my view is an inconsistency and confusion between listening of playback presentation vs. content of musical message. I know that it is fashionable among audiophiles to claim “not listening to audio but l...

actually I agree with Romy, to a degree.... If the amplifier is a push pull device, using my output and input splitter devices of course, then an interstage transformer is a much better choice than rc coupling. Using transformers designed to the crit...

[quote user="Iraschwips"]I imagine this
excellent transient response was limited to a narrow frequency band that was
emphasized by the specific recording? [/quote]
Yes, it is was very accurate guess: it was the “narrow
frequency” and it WAS to a ...

Romy,I understand your situation as a result of the move. It is a good thing because a system that is out of proportion with not work in a family environment and ultimately you will be battling yourself between sound and family priorities and practic...

[quote user="N-set"] The only purely theoretical point which is intriguing for mein the whole multiple drive idea is whether one can achieve a uniform "floating" rotation: the forces perpendicular to the spindle balance out and the spindle rotates wi...

Jessie, a few comments.
The back chamber mechanism is good. Are you planning to do the same in the midbass horn? Since you most likely will not drive your upperbass all the way down I think that the back chamber mechanism will be more effectiv...

After spending a day with RAAL’s “Water Drop” tweeter, trying to make a mounting harness for it I have to tell you that it almost a nightmare to handle it. Around this tweeter I was forced to recognize all objects I my room on magnetic and non-magnet...
