    I've had a q200 for around 3+ yrs now. I placed on granite slab recently with slab on top. I had to leave the plastic feet on to seal the holes underneath. I have recently heard "chaffing" noises coming from the sub during bass heavy scenes and it sounds really awful. I have traced this to the thick foamy stuff that surrounds the cone on the front. I have not changed any settings and the output is not too high. This is very distracting. Is my sub on its way out?

    Thanks

    Have you checked all the fittings and allen bolts that hold the surround and the amp module to the cabinet, if not then do this first as it is possible for them to loosen over time.

    I would get it back to your dealer who can arrange for REL to have a look at it.

    Thanks

    Unscrew the driver from the box and check the seal. You can get sealing material from Maplins I think if it needs replacing. Failing that, try some silicon rubber around the rim where it seals and that should help stop the chaffing.

    Gary.

    If you still want it repaired by REL then if you give your closest REL dealer a call beforehand and explain the situation then I'm sure that he'd be happy to handle a chargeable repair and get it done by REL properly.

    Go directly to REL, they have great customer service and it cuts out the middleman.

    Thanks for all your suggestions. I'll try REL first and see what they suggest

    I've just taken the driver out and checked it. The thick foam surround has come away from about an eighth of the circumference. I'm assuming that this was the cause of the chaffing noise. Can anyone recommend something to stick it with?

    Thanks

    If it's the sealing foam strip under the driver then you can get strips of sealing foam from Maplins or CPCs (or REL probably).

    If it's the driver itself then you can get it proffessionaly fixed by REL or someone who fixes speakers (Wilmslow Audio?). Silicon rubber may work if smeared over where the split is, but knowing how much movement these drivers can do it may come apart again.

    Is the foam you mention part of the cone or is it underneath the basket?

    Gary.

    Hi Gary, its actually not as bad as I had feared. Its where the outer lip of the rubber is stuck to the outside rim of the driver, along the circumference where the bolts secure the driver to the box. This part of the rubber isn't subject to movement. Where this has come unstuck, it flaps, and you can see a gap when the foam ring is squeezed. I have spoke to rel and they suggested a strong superglue to stick it back down on the metal surrounding. I used normal superglue, but have yet to test it properly, first impressions are good though. I've bought some industrial strength stuff from b&q just in case.

    The rubber surround is part of the drive unit, so if this gets knackered a new drive unit may be in order.

    Thanks for your help

    Sounds like good news and a relatively cheap and easy repair. :)

    Gary.

    yes, the super glue used cost 97p and the industrial strength super glue around a fiver. So far it sounds ok. If it doesn't hold i'll use the other glue!
    A new drive unit is around £170 from rel!
