Crossovers are so annoying, about impossible to nail down, and it's almost as though the more you study the problem, the fuzzier the "answer" gets.For now, I would like to more or less forget about "phase" considerations, partly in order to get this ...

[quote user="Paul S"]Greg, I have written about my "DEBZ" speakers several times at this site, [/quote]D. Olsher's Basszilla -- of course! Sorry, Paul, I forgot.[quote user="Paul S"]If I were to do the DEBZ concept right now, I would tune the BR...

A Greek company Arcadian Audio come up with own new horn-loaded loudspeaker.
http://www.arcadianaudio.com/description_style.html
... with Lowther-like single driver. I truly hate those tipe of speakers.
Anyhow, the Arcadian Au...

Hi,[quote user="Romy the Cat"]However, even if you did succeed to preserve dynamics in your line-level transformer then the LF cut off of this transformer will “get” you. The solution is very simple: do not run any transformer attenuators within a re...

Moreart, somebody sent me this link last year. You are surely the DIY pioneer of back loaded Manger.As you probably know this is a touchy speaker to work with. Rated at 91 dB/W input by the factory, we measure ~91 up to near 92 dB/1W/1m in our two mo...

I have seen Beyma rewrite their specs when they redo a driver and even add a letter to the driver for that change, even if it is the same driver.Now I have seen variable FS responses form different drivers of the same model also. I was joking with a...

So little free time, so much to listen to and decide... Today I listened again to a close variant of the previous set-up, using several large-ish drivers basically piled +/- in place, along with a tweeter that will not make the cut. Even though all...

I bought those tweeters for Be Yamamura (second hand from Paul at Wembly Loudspeakers, in London) I also took Be to Heathrow Airport to take a plane to Brazil to install one of his truly superb VT4c stereo amps! It was the morning of a great wind ...

Being both fairly lazy and fairly cheap with respect to audio, I remain very interested in theFR SET/dynamic speaker dream. Also, I am generally both weary and wary of the extreme complexity/difficulty engendered/entailed by othe...

Haralanov, as far as I know, Madisound does not offer my ribbon. Mine is not a stock Fountek, but it is a re-worked version of the old, discontinued Fountek JP2, a very narrow "naked" ribbon (ie,. no coating), and 97+ dB efficient. I got my Audaphon ...

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...

[quote user="Antonio J."] I have listened to some expensive speakers from B&W, Wilson Audio, Dynaudio, and also owned the SF Amati, you know already. Musically these ones were more musically interesting to me than any of the others, but still wer...

Hi Paul,
The L.Cao are quite nice fullrange drivers at a reasonable price. Compared to Lowther EX the L.Cao lacks some dynamics but have a better tone and are more homogeneous. I am no fan of whizzer cones. To use it as a midrang...

MoreartDouble-driver "back horns"? I am not sure what you are asking about, or what exactly you are promoting, but I do not agree with lightweight, square-section horns, because I have never heard one that worked, apart from shifting certain frequen...

John, a few corrections for start
First of all the gullible and moronic are not interchangeable words and I never use one instead of other. Second Audio Note Ginga does not look like traditional Micro. It has oil suspension and God knows what ...

I was pointed at a site where people debating the subject of 2A3 vs. 45 vs. AD1 vs. RN604 vs. YO168. Naturally they pointed out to my site, bringing my articles from this thread on the same subject as some kind of reference.
I read their comm...

[quote user="guy sergeant"] I have not drawn any conclusions about how this amplifier might sound. I cannot imagine how the input stage you use will behave and how that will impact on what the 6C33 does. As I've said previously the Lamm amplifiers us...

Chris, I have no experience with good sounding SS amplifier that might drive high sensitive horns. I also have no expertise to build such an amp. From what I trued before I have learned that in order to sound more or less acceptable the SS should run...

The main "technique" I use in "problem solving" involves a sort of Hegelian turning and re-turning of/to the object of attention (or, my perspective...) to get as many "views" of the object as possible. This sort of reflection has recently broug...
|

First off, I will point out that neither Silbatone nor I claim or agree that the Aporia horn is a point source, because clearly it is not. The sound comes from two "areas" but even that is not a particularly useful notion.Although some do make that c...

This is the idea that I like. It looks like it is a Slovakian company and this amps is two stage with a reasonable driver and it looks like they make their own 2A3.

Just some additional thoughts on the new generation of 2A3 tubes. The only ones I would seriously consider are the Kron Enterprises, the Sophia Electric, and the Emission Labs tubes. If I did not hear these side by side over an extended period of ti...

[quote user="guy sergeant"]I feel you may be doing John Attwood a disservice here. There are two reviews of this book. The first one which you quote extensively from appears to have been written by Lynn Olson. The second, much shorter review is ...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...

Hi everyone,Ive been tracking this exciting conversation for some days. One from outside may think this is weird, we are making a lot of air about some sound-description without getting to the point. Im (or was) normally more rational. And if I read ...

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="serenechaos"] "I think the ultimate length of the upperbass horn is 3”- 4” throat. With longer horn it would be very complicated to time-align it as the horn will mask out the MF driver."
Is this also why you use tractrix curve f...

Joe,
The “decoration” you described came from the fact that you wrote your message on MS Word that adds ugly formatting when you paste it into native HTML editors. I also write in Word and I uselessly before I unload my posts I paste my Word’s text ...
