B&O Beovox 3702 photos.



I refoamed these yesterday afternoon, then gave a light sand. There are some rings that I can't completely remove, but all in all they look pretty good. They were designed in 1972 by Jacob Jensen, a Danish industrial design god, who pioneered Bang & Olufsens signature look. These were the smallest 3 way systems in the range.

The midrange drivers look like toys...they absolutely aren't (the tweeters are Philips, I don't know about the mids or woofers, which aren't marked). These speakers are fine and mellow.

OMG! I have a pair of these in rosewood. Picked up for $15 in great shape. Haven't been able to find much about them. I believe mine need to be refoamed but didn't know how to remove grilles w/o damage. They sounded awesome till foam went.
Thanks for the great blog,
Larry

That philips tweeter is pretty bad imo. I have refoamed the type 6263 and they sound excellent.

I would absolutely replace the midrange cone element. Also consider replacing the woofer
if it is of the old foam variant. You will also need to replace the electrolytic capacitors in the filter that have dried up. At the same time you can adapt the filter to the replacement elements. If you do this you will get an 100W RMS top performer that will
really be something than just a collectors item!

Hi, I have just inherited a pair of these speakers. They're unused since the early 1980s. I've wired them into my TEAC amp but the sound is very slight and crackle. Is there any adapamtations I need to make for the speaker wire? The original connections were incompatible with a non-B&O receiver so I snipped and stripped the cable (!). Any advice as to how to proceed or do you think they may just be knackered?!
Thanks
Vincent

What was the ohm rating of the original woofer that was is this speaker? Mine is not original, has Technics woofers installed.

The woofers look to be some variation of Peerless P825W and have AlNiCo magnets, they are 4Ω.
