Hello everyone, For those who are looking for information or advise concerning ELECTRO-VOICE vintage speakers, don't hesitate to ask me : I have a comprehensive data base concerning all E-V components back to the 60s (data sheet, plans, reports) EM

Amazing! I was just about to ask an EV question, and here you are. . . . I have a single Senior Centurion and I'm thinking of using the 15W woofer as the sub in a home theatre system. Do you have the specs on this driver and/or plans for a suitable enclosure? I had to shed the outer enclosure in a recent move, and would like to start over in a new woofer only enclosure.

Hello, I have checked with my documents. I don't have the specs concerning the 15W, which was discontinued in the 60s. But you can get some interesting information from the attached link My advice is that this speaker is nearly 40 years old, and so even if you got the original specs from E-V they would be wrong because of the ageing of the suspension, alnico magnet, etc ! But it remains an outstanding speaker. TMHO, the smart solution is to make the today's T/S par. measurement of your 15W with modern tools or according the method you can find everywhere on the web, and use them for your enclosure calculation. Take care, ERIC

Hello PETE, E-V T35 : The earlier T35 version came with an ALNICO magnet, 16ohm impedance and 57dB EIA sensitivity rating. Later (end of 60's) was introduced the T35A with 8ohm impedance and still 57dB EIA sensitivity. In the beginning of 70's, E-V documents change EIA sensitivity to standardized sensitivity and so rated T35A with 104dB @ 1W @ 1m . 2 versions : ALNICO round magnet and later CERAMIC rectangular magnet (1978) with same given characteristics. This is valid of course for recent speakers. Due to ageing of alnico magnets, the sensitivity of your T35s should be slightly less now, if older than let's say 10 years. Best regards, ERIC

Thanks Eric, wow, I didn't think they'd be so hot!! mine are the ceramic version. I just have to find some mid/bass speakers to match them with.Do you have any opinion on which way to orient them? In the early lit, EV were saying the long axis should be vertical, but Klipsch used them horizontal... Cheers, Pete McK
