HI,
I'm working in A 6 Way system,
TRIAMP,
WITH:

Phaseless B&C18RX infrasubwf 20-60 hZ- (KEF LOAD LIKE)
EV 180A low woofer 60-100 Hz closed
EV150 A woofer 100-250 Hz closed
BEYMA 8 MI100 250 - 1500 hZ
DINAUDIO M560 ESOTAR 1500- 4500 Hz
HEIL ESS ID 4500- 20.000 Hz - Modded by special foam pads
by Phaseless into pointsouurce 😎

SLOPES 12,12,6,6,6dB/OCT ;-)😎

It is a friend of mine sistem.😱

I Have datasheets of EV 180 AND 150, BUT not the "A" version.
Is there differences??😕

if yes , someone can post a link?? 😱

very thanks🙂

Cheers

Thanks,
really I don't know which is differences between 180 and 180A..😕
can you post your datas/graphs?🙂

cheers 😀

The EVX180 was a foam surround, it was quite different as far as TS parameters from the 180A and 180B.
The suspension was rather loose, sensitivity and Fs were lower than the later versions, may have been 25 Hz or lower.
The 180 foam surround could be torn fairly easily, and since they were touted as a high power PA sub, EV quickly changed to pleated fabric surrounds in the 180A (and B) which were hard to break, but did not go as low.
Unfortunately, I don't have the 180 spec sheet.

The EVX 150 was a bit different from the 150A as far as the TS parameters, though I don't recall much difference in the sound between the 150 and 150A.
There was a change in cone materials to keep the carbon fiber from starting on fire at high power levels..
