Tweeter pressed in B&W

[alistair1234]

I’ve got some bowers and Wilkins bookshelf speakers that I’m looking to move on but unfortunately when moving them back in to place recently I’ve managed to press one of the tweeters in. Any tips on how to rectify?

You should be able to buy spares direct from B&W at a reasonable cost. My old pair of DM602's both had the "toddler" treatment and I thought at over 10 years old I'd have no chance of rectifying them. I was gobsmacked when B&W said they could still supply replacements. They were a piece of piss to swap out.

I’ve done similar with a Monitor Audio tweeter and was able to source a replacement from the factory for a modest sum - you should be able to do the same:

I agree - try a vacuum cleaner hose just off start off low.

Before the dyson, try cellotape. Sometimes they only need the smallest help to pop out again. Lightly apply then pull off a few times (oh err!!!)

Leave a Hoover well away from it ! Could suck the cover right off . Try a drinking straw and suck the dent out .

I bought a pair of replacement main drivers from B&W for my 602s about 2 years ago. The speakers must have been 14 years old by then. They did say there weren't many left on the shelf and they weren't planning another production run.

Just put your mouth over it and give it a light suck . . .

Thats a metal dome tweeter - it wont suck out whatever you do, replacement is the only option

Don't use a hoover! Might work on soft dome tweeters but not metal.

On the previous generation (1, 2 and 3), bowers correctly identified that weeters were easy to damage so made the diaphram replaceable (rather than binning the whole tweeter unit). If you take out the main driver, you can put your arm in and the hf unit comes out with a 1/4 turn.

3 screws to take off the tweeeter diaphram, then smooth it out with a soft tissue from behind.

This _will_ leave "smiles" on the tweeter dome but it's 95% better for free.

If it doesn't work, get a replacement diaphragm from bowers.

As already suggested, avoid vacuum cleaners - you'll only do more damage !

Prices for replacement B&W parts arn't cheap, I think thats a 68x Series 1 (US site giving prices):

For older models, they have run out of some spares, but yours is a fairly recent model - you can give them a call to find out

Sellotape.

Work it in gently with your fingernail and slowly pull. Repeat until done.

You are sometimes left with a small crease or dimple that won’t cooperate. If you feel it is going to prevent the sale then swap out with a replacement.

They look like 685 Series 1s.
You can't buy replacement diaphragms for those, only complete tweeters.
There is no way to fix them by sucking them out or with Sellotape unfortunately.
You'll probably need the serial number to get a new one as there may be different batches.
You're likely looking at about £40 per unit.

I'm only trying to help

On a serious note it has worked for me on soft tweeters (oh errr).

I've no idea on metal ones though.

If they don't sell diaphragm s for the newer series, dent repair might be the boy!
