What's wrong with my speaker?

Blue Bird Music is the domestic distributer for Vienna Acoustics. Call them for advice and a repair option. That sounds like a repair not a replace.

Either the voice coil is rubbing, or the speaker is traveling out of its intended  range of motion, or both  I once bught a set of B&W DM 14's which had tweeters substituted from a cheaper speaker.  They looked identical until I removed them. The popping and crackle at high volumes was because the cheaper speaker had a smaller voice coil and magnet, from a cheap B&W that cost a quarter of the DM14 price. You might be able to order a new driver, and on domes, replace only it, but you will not be able to straighten a bent (overheated) voice coil, unless you value your time at about a nickel an hour, or have a lot of experience, which practically no one does, because people value their time.

Pressing on the driver can change the alignment while you press, and it can limit the travel.  You might actually try an ageing woofer trick. Put the speaker in upside down.  I have seen (i.e. heard) this realign a sagging suspension enough to cure the problem.

Hey oldhvymec,

I do the same thing to my subwoofers. Once a year when I change the filters in the furnace I rotate the drivers 180 degrees. When I built the enclosures I set in stainless T nuts for the driver bolts which are also stainless. I sprayed the heads satin black so they would match. They are also Torx bolts which I love. They do not cam out or strip. I doubt any of this would affect these small, light drivers. It is TOAST. Can it. Hopefully the company will send you a new one fast. This is always where the rubber hits the road, service. Let us know how they do.
