Picture of Bang and Olufsen Beovox Woofer Replacement (easy)
How to replace a woofer in a beovox model B&O speaker. They commonly rot out, and it's an easy fix, as long as you aren't an anal retentive B&O fan who wants everything original. I chose to replace mine with Goldwood 8" woofers, about $17 each, available at partsexpress.com. They now sound fantastic! :)

Beovox S55 Bang and Olufsen Woofer Replacement (easy)

Step 1: Check your woofers, mine were shot

Picture of Check your woofers, mine were shot
B&O typically uses really crappy foam suspension on their woofers which rot out in a 5-15 years. Mine were shot, so I ordered new goldwood woofers to replace them. Just be sure they're about 8" in diameter, and more than 6.4 ohms (the original impedance of the freaking weird woofers they used). This shot is after I had already taken them out.


Lay speaker on it's back. Use a phillips to remove 6 screws holding the entire plastic speaker face onto the cabinet. Seperate. Lie the black plastic faceplate on the ground, with the speakers facing down. Snip the wires to your woofer, as closely to the woofer as possible. Remove the 4 phillips screws holding the clamps onto the woofer. Now, compare your old woofer to your sweet new one!

My B&O S45-2s have rubber surronds and after 30+ years, they still sound great.

Nice job. Where did you get those speaker stands from by the way?

Don't the guys at B&O offer lifetime warranty on all of their stuff?

As long as it makes you happy I guess. Foam surrounds were common for many years. They were great in that they took Zero hours to break in. They sucked because the foam would in fact deteriorate. To fix this problem they came up with re-foaming kits. You can still get re-foaming kits on line for less than what you have in new drivers. And yes, all of the comments about how asininely esoteric the B&O stuff is are true. Eff those guys.

I checked for refoams, but for the LEGIT refoams that are exactly the right size, shape, and strength of foam they were $22 plus shipping. That, and I'm not sure I'd get do it perfectly, so instead I spend $34 plus shipping on entirely new drivers. Not a bad idea, IMHO. Especially since the new ones are so much better. :)
I'd definitely get the correct foams. Speakers, especially high quality ones like B&O are designed with everything perfectly matched, and finely tuned. Changing the drivers might sound good, but numerous things will now be out of balance. I can guarantee using the correct drivers (with new foams) would sound much better. If you don't have the confidence to do the refoam, find a handy friend :)

I have the B&O S50 speakers that I bought in 1981. I replaced the woofers with the Goldwood 8" speakers and they are like brand new speakers now. Thanks!

Not bad, I've got nice technics towers, I'm not sure if they're rubber surround foam or not (most likely are as you can tell it feels like they're worked in) But I think the guy before me had cats or something, the grill has scratch marks and the foam on the top woofer on both have small little holes in the foam. This prolly won't make it sound worse will it?
