[quote user="Thorsten"] So, at least in commonly observable and observed terms and when used as intended the S&B line transformers are notably more capable at low frequencies than your LF OPT's in the Super Milq.[/quote]
I have no doubt but ther...

I heard back from Lamms about the relay pulses. They suggested I bias the amps again and then Lamms went silent when that didn't work. But the problem disappeared when I got around to replacing the 12AX7s that came with the amps.&nbs...

user="kodomo"]In my first design, I kept them all in a vertical line.
It had one channel less back then. When I added the 1" throat JMLC 1000, I
decided, as the tweeter operates over 9.6k, the slight misalignment may not
matter. Still, I k...

[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 2nd order crossover both on the upper knee of the ob bass section and on the lower knee of the midbass section. My measurements show phase response and the summed spl is as good as it can get. Have you tried the direct servo technology or do y...

Now I have been listening the different crossovers trying to shape the new Macondo general balance. This is so fascinating ceremony that I do have a lot of fan. The things doing alone very well. I boosted upper bass and it worked now very-very well....

This is my first horn build effort. Been thinking about this since starting to build loudspeakers and finally have a listening space big enough to support a horn system. This is where I am at now, I know there are opportunities for improvement. And I...

[quote user="Brian Clark"]What you have there Romy is essentially the cartridge Ortofon introduced in 1948, the first production moving coil cartridge. The motor is the same, just the "suspension" material changed from india rubber to a modern elasto...

Romy,
Funny stuff... especially the the AN piece. Equally surprised octopodes ? Brilliant !
As for the Bruce Edgar post ? Not as funny. And it's off base.
The Titan II system has a straight axis upper bass horn instead of a folded upper bas...

The following link will take you to images showing my construction method for small to medium-sized horns (click on the images... to view the explanations) : http://s172.photobucket.com/albums/w3/jessie-dazzle/400Hz%20Tractrix%20Horn/ Since these are...

Somehow I massacered the formatting of the last reply. The past days I was listening to the speakers in every imaginable configuration. Sometimes I based my changes on "accepted theory" of crossovers and math, other times I just made...

Well they are not my sound either...I've gone tractrix on upper mid and mid horns and exponential on mid bass. Still have the tapped horns.The now black horns are someone else's and are intended to be used in light / small scale PA. That's the idea a...

How did you determine that it is the horn. What makes you think that you can damp a horns mouth at 200 Hz. Have you never read what a room does to frequencies under 400 Hz? If not, check this site out: http://amroc.andymel.euMaxx, I think that you ar...

Romy,I say "Go for it"! With your usual documentation, we can only profit from you getting the hernia first. I got mine operated on last week, so looking is all that I can do for the next 3 months.One thing that has always roused my curiosity: your ...

Hello RomyI like Shelters as well, so I finally scrubbed-up enough money and began to search. I was always happy with 901, but there were none around. Last night I got a 90X, with (supposedly) around 100 hrs on it, within driving distance. So today I...

feeling and you will change this feeling many times. To accommodate a pair of 42Hz

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA horns or horrible acou...

Zanon, I do not mean DEQ, but that is one way to do it. D[SET] is another way; and it can be done in real time, by a couple of means.If you actually settle on the mid-field monitor approach, you will want that sort of speakers installed before you g...

Robert, Agreed... many people rave about the FE126E in just about anything... yet, I find them irritating (upper midrange shout) before 1-watt sets in. The F120A (in a simple ported enclosure) is a completely different sounding driver. Sti...

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

IME (i.e. some pm's one dx), the Ex-4 sounds the most civilised -- and this, only up to ~10kHz or 1-2kHz lower.It doesn't sound bad in a tractrix, unlike Paul S' experience with a dx4.A horn is also useful to provide some extra spl (106 spl at 1+m wi...

It is hard to get used to the idea of 1 or 3 LF channels supporting a "stereo" hi-fi. But the way it winds up working is that the "wrong number" of channels, or sources in the "wrong spots" can make things sound worse, because of cancellation an...

I came within an inch of mentioning Gould in the first post but decided to leave it to Fischer, whose performances earn a dedicated post, especially as noted.Yes, there's no way around Gould in his high manic perfection. But too much of Ba...

[quote user="jessie.dazzle"]7) Location of power amps : Yes, the power amps sit within the frame, on their own sliding support between the Upper-Bass and Upper-Mid horns. For the moment I am using a pair of ML2s from 60Hz and above. (below 60Hz I use...

The Delta Pro-8B looks like a very fine driver, in fact on the paper it is even better then Fane (with exception of sensitivity and inductance) The problem is that no one knows how this driver will sound until it is loaded into a specific horn, no o...
