Another Electro Voice Interface D Restoration Thread

Also, on the subject of grills, was the original grill cloth brown or black? I've seen photos of both, but I'm not sure which is original. It looks like it may have changed over time. Mine have brown grill cloth, that appears to be original. Mine also have the milk chocolate brown painted front and rear baffles. I've seen pics of Interface D Series IV speakers here on AK that have black grills and black painted front baffles. So, it looks like the paint and cloth changed color as they progressed from the original Interface D to the Series IV model.

When I redo my cabinets and grills, I'll probably stick with the original brown (or at least as close as I can get), just to be true to the originals. Although, it's REALLY tempting to try a beige/camel grill cloth similar to what came on the JBL L300 Summits back in the day.
 
Mine are Series II : cloth and emblem original. My buddy who turned me onto these has a pair of series 1 & 2. The color of the grill cloth is slightly different (lighter I think) on series I. I'll take pics of them next time I visit him. I know that the front of a series I is brown and the front of a series II is black. Here's some pics!

The corners seem to be the weak point on these grills. If pulled on and off repeatedly the joint weakens and needs either rebuilding or additional support.

Thanks for posting the pics! Now I know what the badges look like, I know what to watch for on eBay.

Yes, I'm sure the grill cloth on my Series 1 speakers is original. I described it as milk chocolate brown. It's definitely not a dark brown, more like the color of a Hersey bar. As clean and sleek as the newer Series IV models look with the black painted baffles and black grill cloth, I think I'm going to try to get as close to the original medium brown as possible - at least initially.

Once these are done, and it'a going to be a while, I think I may try to make a second set of grill frames. I'd really like to see what these look like with beige, or camel, colored grill cloth. These are very physically imposing speakers. Even when they aren't playing music, their size and bulk draws the eye to them. They can physically dominate the room without making a peep. I think a lighter grill fabric may tone that down a little and help them blend into the room decor a little better. I consider my "hifi" gear part of my furniture. It's an important part of the room, even the focus in my case, so I want it to blend cohesively and harmoniously with its surroundings.

Though I'm always fond of saying that I hear with my ears and not my eyes (therefore I don't care about the aesthetics of a speaker), I have to admit, I always felt the "D's" were a fine looking speaker. Very stout looking. (ultimately became my smallest pair! :yikes:)

Jan Delange's gorgeous L300 Summits served as the inspiration for my reimagined L36 Decades:

No real updates. The caps and resistors for the EQ conversion are on their way from PartsConnexion, but won't be here until next Friday. So, I thought I'd share this:

EV-Interface-D-Warning.jpg


It is my considered opinion that every household should have at least one pair of speakers with a similar manufacturer's warning label attached.

In all honesty, I haven't heard a pair of Electro-Voice Interface D speakers since my freshman year of college. One the upperclassmen who lived across the hall from me had a pair in his dorm room. The school I attended was a small private school in Northern Indiana, not too far from Buchanan, MI where they were made. His dad (or maybe it was his uncle) worked for EV. There were actually some pretty impressive stereos in that dorm, but when push came to shove, his Interface Ds won the dorm stereo wars - hands down. I kinda felt sorry for the international students who lived on the floor below us. We were all into Pink Floyd, Led Zeppelin and Black Sabbath and we all played it LOUD.

I still have all my albums from back then, as well as the Bang & Olufsen Beogram 3400 turntable I bought my freshman year. Can't wait to hear these babies sing.

Heres an old pic of my D's that I rehabbed,i found them in an old building ubove a nasty meat store that sold horse meat.They even had a old womans/mans long pony tail cut off and stuffed up into one of the down fireing woofers{had to refoam}.
I ran these for yrs with high powered SS amps and yes they go loud and sound decent at those levels but when I went to vintage tube electronics that's when I narrowed in on just how good these speakers can sound.
They never seen a SS amp/preamp after that,stricctly tubes.
Here there running with my Fisher 50A triode tube mono blocks
Also sounded great with a Dynaco st70 and many other tube amps

Ohhhhhhhhhhh!!! i SOOOO agree!, that warning label :deal:
 
Finally hearing these for the first time. All drivers installed and working, the EQ installed and working.

I don't have any photos to share. They look exactly like they did when I got them (see my first post in this thread), but are now fully functional for the first time in over 20 years. They are just sitting here in the middle of my living room rockin' the house.

I posted my quick first listening impressions in the big general EV Interface D/Sentry VI thread, but thought I'd share them here as well:

OK, both speakers reassembled, all drivers working and the EQ hooked up.

The speakers aren't properly placed in their intended listening location, but the comments about them shaking the foundation of the house aren't exaggerated. I'm just driving them with a little Pioneer SX-737, with the volume control at the 10 o'clock position, listening to Bela Fleck and the Flecktones - Flight of the Cosmic Hippo and Victor Wooten's bass is causing the glassware in the kitchen cabinets and the glass shelves in the bathroom to rattle. And, they are sitting on carpet right now. I haven't even moved them to the usual listening location on the hardwood floors.

I'm going to have to do some serious vibration isolation before I even attempt to play them this loud anywhere near my turntable.

I just want to add that while the bass is VERY prodigious, it is not at all boomy, not even in the slightest. It's very tight and gives more of the impact of a live performance than any other speakers I've ever owned. I'm not set up to take measurements, but I suspect that the bass response is very flat, with no peaks, down to the rated 28HZ. In other words, I suspect the speakers are performing the way they were designed to perform and the EQ is doing it's job. It's quite impressive.

Although the bass is immediately noticeable, I'm also impressed with the VMR. Female vocals, piano, acoustic guitar and string instruments all sound very realistic.

They are currently placed too close together to comment on the imaging, but I suspect that too will be impressive once they are properly placed.

I still need to embark on the cosmetic restoration and recapping the crossovers, etc. I'll get to all that eventually, and will post photos whenever there is any significant progress. For now I'm just going to kick back and enjoy listening to my "new" Electro Voice Interface Ds.
 
Congratulations on getting these singing again! I have been watching this thread with great interest and jealousy. My cousin kicked started my audio obsession when he purchased a pair of D's and a SX-1980 as a college graduation gift to himself. I would spend weekends at his house enthralled with what I was hearing. A Holy Grail speaker for me!
 
Interface A
I know this thread is for the Interface D but I have a pair of interface A speakers. Sent them in to be re-coned about 15 years ago and the guy replaced one of the rear tweeters without asking and replaced it with a really poor tweeter. The sound is so annoying that I cover it with a piece of cloth to muffle the sound. I've been looking around for a replacement tweeter but can't find any and I'm not sure what would be a good/proper replacement. All I know is that it's a 2.5", 8 ohm tweeter. Having trouble finding out any other information about it. Any help would be greatly appreciated.

Try contacting @GordonW. He might be able to help you out. He basically built a replacement woofer for my Interface Ds from "spare parts" (frame and magnet from a different EV woofer, combined with an Interface D recone kit). He knows his stuff and does excellent work.
 
I have had a pair of D's for about 6 years, and I haven't had anything else that can touch them. Some NS1000s came close, but that was about it. They didn't have NEAR the bass of the D's though. SMOOTH midrange, they are heavenly. A good friend sold them to my wife for my 40th birthday. He bought a pair that were cosmetically perfect, but don't sound as good as the ones he sold me. Of course, he didn't know that when he sold them. I have heard the bi-amp plugs are unobtanium. Tubes are incredible on them, right now I am using a BGW 250D and it is very nice. I won't ever part with them!
