[quote user="Jorge"]One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tr...

A few things I would like to say in context of Pham’s playback.
I will leave his infatuation with turntables alone – man like to collect turntables and he within his constitutional right to do whatever makes him happy. The problem that I see ...

I did not see in your post any “sad truth about BMS”I would stick in the JBL 2440. It is relatively inexpensive. Has practically the same performance as the hipped JBL 375 and all together a good performer. It’s diaphragms are wildly available and it...

I had a SG370 mid apart only yesterday.I should have taken a photograph.I have also seen the inside of the tweeter.They are very similar,so I have no reason to suppose the low mid SG 505 will be much different.I'll try to explain.I think they a...

These are clearly JBL pots and back covers (which have been milled flat). The refinishing job is quite nice, but the origins are clear. Also, the phenolic diaphragm is clearly for the 2482/2485 (and looks like a JBL part), which has a slightly wider ...

Jorge,
You're quite welcome to visit any time you are in the SF Bay Area.
There's a photo attached to this post of my Blokhorn system ( modified Edgarhorn System 80 ).

Paul,The two channel system is separate from the HT system - the gigantic plywood folded horn subwoofers support the screen but that's the only connection to the HT audio system.The HT system is three Orb Audio 8" powered subwoofers, 3 x Gallo Ref. S...

A somehow-related thing is "texture", and - of course - what we want is the "availability" of a range of musically relevant textures rather than textural "overlay". The S2 and the Altec 808 had this potential, but I never heard it from the JBL 375, ...

[quote user="op.9"]Anyhow, what are the 2" comp drivers that ARE any good and are available comercially? I didnt go with any JBLs because I had a very bad time with the 2427 1" version, could never get any music out of it. [/quote]
I would be surpri...

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

The room is beautiful, and I love the tree stump "rack" with the amps, it is clearly a work in progress, but they already put in the "Western Electric" badges on! It talks a lot about their priorities I guess!They have what seems to be a midrange ...

Yes, it's been that way for me, too, for years, now; "solutions" are no longer considered good enough if they yield only intermittant Musical satisfaction, or if getting and keeping things optimal for each session takes "too much" time and effort. Li...

[quote user="CO"] Ive been building and improving my own speakers the last few years and at this point i'm thinking a fully horn loaded setup ( 3 way + sub ) is the best route to take to get a speaker capable of faithfully reproducing the elect...

to get worthy advice, perhaps you could share some info about your present system and musical tastes, also what it is you like and don't like about your present set-up, and how you'd like to change it, beyond "flat + extended highs". If you have rea...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

At some point recently I became particularly aware of the
fact that the sound from the Loudspeakers has transformed significantly over
the five months that I’ve used them, not in the sense that the character of The
Loudspeakers has changed, ra...

I would like to pass some summarizing observations and some generalizations regarding the entire “Water Drop” project.
THE IDEA
The idea of trying to find a tweeter to compliment Macondo was a good idea. Many of you know that I was proudly declari...

The best driver I have heard is the TAD 4003.
It does not use the secondary resonance of the suspension, as described by Duke LeJeune above for the TAD 4001-4002, to extend the response towards 20 kHz, but has a natural roll off from app. 15 kHz.
I...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...

Yep, Stefano, it looks like we do have similar views about the subjects we touched. Let go back to exploring one of the terra incognito of compression driver – the sound of Goto.
I would insist is that to judge sound of Goto driver from the installa...

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...

[quote user="Romy the Cat"] The S2 has own very idiosyncratic upper range with own helpful resonances injected into sound. I feel that that original metal suspension diaphragm does it bolder and more aggressively then the plastic suspension dia...

[quote user="Kerry Brown"] For years, I used to have passive line level filters and tube amps - single ended 45's and 2A3's.
To make a long story short I am much happier now. Screw tubes ! ( Don't hate me. ) [/quote]
Kerry, I do not think that som...
