I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...

Likely, the wider ribbons are less good for HF-only than a long, narrow ribbon, like the G3 and G3Si use. Across the board, the larger the ribbon gets (and the lower the ribbon is made to go), the worse the dynamics at a&nbs...

Thanks very much Romy and Dan for the input.
With the exception of a structure to locate the horns, I have all the tools necessary to make the measurements.
Though this is all happening in France where DSPs and TADS rule* (see note at end), all...

[quote user="cv"]Little suggestion should all else fail - you could have a rudimentary phase plug machined that would give you the same (or similar) compression ratio as the original but only one annular exit path. This might preserve the driver char...

Thanks for your quick reply. I have been to assistance audio`s website, however was unable to find such model, but is possible they just disassembled the tweeter or whatever.This is really interesting news, about their violin reproduction, me too wou...

One basic requirement of "Pro" speakers is that they play LOUD, preferably day after day (night after night), without blowing up. Most pro gear is designed with volume (power handling) and durability as the first considerations, and the "sound man" ...

Ah yes, sorry - that wasn't remotely clear. The drivers I have played with briefly are S2 and field coil RCAs, both have the same 1.5" throat. I was referring to my initial impressions of the sound on Martin Seddon's 160Hz horn (T=0.8 JMLC). Previous...

[quote user="Serge"]Romy consider that the engineers who did your Altecs in their worst nightmare could not imagine their lovely cinema speakers would be used with solid state amplifier which badly distorts on LOW power levels. It has 100 crappy watt...

I think most of reader get my point of the car examples. The main point is to follow the manufacture recommendation on how to use the driver. Of course, if you want to do something different, that is your choice but don't come back and blame the dr...

So, with this horn I got the sound I was dreaming for!Currently system consists of 4 channels:1. RAAL Lazy Ribbon (14k+)2. JBL 2453 in 550Hz LeCleach (1200 - 14k)3. JBL 2490 in first part of own JBL horn (300-1200)4. 12" Supravox in 42Hz 2m long horn...

hi RomyI agree with the technical design issues. Though i experienced that for most modest domestic dynamics first order xover can work surprisingly acceptable.Also agree with bad impression of exhibition experiences are steered by many factors and s...

I have heard several Tannoy speakers in the past, but have never heard the quality of sound Romy has obtained with his brain child. I don't know whether it is the speakers alone or his setup which has allowed his system to enthrall so much more than ...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...

[quote user="N-set"]just a minor tech remark (feel free to ignore): the big-ass elco is theoretically still well in the picture. 10uF will have 320Ohm@500Hz, which is a fraction of 20Ohm R+3mF elco.[/quote]Jk, actually it is not exactly accurate.
