[quote user="rowuk"]In my over 50 years of personal audio, I think that I can explain part of the speaker/amp compatibility. This opinion is everything but comprehensive.Bad matches in amp/speakers manifest themselves very often in the bass. Please c...

I have not read this book (the wood effect) and if you have shopping link please sent it to me.I am not sure but It seems even amplifier speaker connection is important for sound.In past I have inverted the signal phase in my DAC and also inverted sp...

These were my first high end speakers purchased in 1980. They have been sitting in my basement for about 30 years as I've gone through everything from VMPS super tower 2 ar's to B&W 800 to my self built Edgar horns, which I’ve been using for abou...

I would like to share some ides what I would like to do in my monitor project. This are just intention and I did not try to put it all together. Probably I will do it with the next few weeks.

I recently completed some upper bass horns which I'm now enjoying very much. Sadly I lack the skills of someone like Jessie so my efforts are crude in comparison, but they are working well for me which is the main thing.I already had some old frontlo...

[quote user="Antonio J."] Anyway, going back to the subject of the thread, why would you implement the ambiance retrieval at speaker level and not at the "pre DAC" one? After all we'd like to have from CD's something closer to what TU-X1 does.[/quote...

I think I am correct, but the problem is directly related to loudspeaker impedance. I did the first round of calculations by hand and when I got the results I searched the web for a calculator that someone has made so that I did not have to write it...

I am not "working backwards" from a tweeter. I presently use Harbeth M40.1s, but having recently heard the Living Voice Vox Olympian and an Audio Tekne horn implementation of Ale Acoustics drivers, the experiences opened up new vistas of what is poss...

Some of you probably know Jack Bouska, I didn't find any links to his system here at GSChowever. He documented the technical steps that led to his system in a very detailed way. How his methodology relates to Sound can be discussed........

Well, I have just taken receipt of my Orelo speakers (pic attached) - the bigger version of the Orelino speakers, with 3x 15" bass drivers per channel as opposed to 3x 12" drivers.I realize that Romy doesn't regard the coaxial BMS mid/high compressio...

Hi,I keep for many years a set of speakers, JBL 2225h, JBL 2105h and JBL 2403h and I'd like to build a reflex compact speaker with a good low response (see the picture 1:10).

[quote user="Paul S"]You have mentioned that you want a much larger enclosure for your oops unit. I was then wondering if you aim to merely broaden and/or lower resonant response or if you planned to in some way tailor resonance as it rela...

Jim Hi, my name is Keith Cooper, I own a pair of Alpha's had them here in London for about a month now, they are superb ! I heard some Trio's which initially stirred my interest in horn loudspeakers, I know Ralph is looking for a US distributor...

[quote user="stevie7V"]Further, as Shelley is also a very accomplished classical pianist, I'd expect his system to sound very realistic as well.[/quote] There have been a lot of discussions about this before, but one must always take this sort ...

[quote user="steverino"]I agree that the published curves don't look bizarre for a box speaker. [/quote] Hmmm, I would like to note that my reference to "given topology" did not imply the "box speaker". Even a multichannel box speaker might have opt...

I have no idea how a “typical

There are plenty of examples of feedback that seems to "work", from record cutting lathes to player pianos. Why have I never heard musical LF from a servo design? Not kidding here, I actually want to know if I missed something.I think there is always...

A few days ago in the thread “Who Builds Horns”: http://www.goodsoundclub.com/TreeItem.aspx?postID=3226#3226 there were mentioned the Cessaro Horn Acoustics Company from Germany. The company has an interesting model Gamma: http://www.cessaro-hor...

I've been thinking about how I am going to wire these Bass Cannons as well as the horns on the horn stack. For some time now I have preferred ribbon/foil speaker cables for the relatively low sensitivity speakers I have been using. The reason I bel...

G'Day Rowuk,Thanks so much for the quick replyThe drivers were recommended by the person who made the cabinets. All three are supposed to be quite well regarded.Initially, the project was just going to be 2 x 10" and the Beyma tweeter, which in itsel...
