Very Nice Stephane

You've effectively built a modern version of the Westrex 20/80 System ( though I like the looks of yours much more ) .

In your opinion , which of these two horn types gives you the better imaging ( Acoustilens or the GPA 6040 ) ?

>< cheers


ps 1 ; here are 3 examples of the original woofers ( courtesy eBay ) .

- Obviously, technology licensed from Altec ( I hope W.E. actually paid ) .

ps 2 ; I like your solution for mounting the lens without drilling holes into the vintage metal .

Hello,
The image of WESTREX is more natural.
Details: westrex the horn are made of fiberglass

Hi, all!

[Flaesh]

I have answer, price is acceptable for me.
Stéphane, did 399 need the tweeter? (your impression - no? )

[stephane RAME]

Hello,
The 399 has a frequency response that drops to 16 kHz, but added a tweeter according to his tastes.
