I just recently purchased a set of used PSB Alpha B's. Everything was fine until I (due to my own clumsiness) managed to get the sleeve of my sweater caught up with the tonearm/cartridge of my turntable as I was lifting up to flip a record over. The tonearm slammed down and hit the record as I pulled back when I felt the contact, and a very loud and audible series of pops and clicks followed as my amp was still at the level it was when playing the previous side of the record (I'm new to the vinyl world and haven't quite gotten into the habit of being more careful + reducing the volume on the amp when flipping sides).

Anyway, since this happened (just this afternoon) there is an audible "fluttering" noise whenever the turntable puts the needle to the record (I suspect there is also damage to the cantilever), this effect can be heard by listening to the short clip I uploaded to Youtube: http://www.youtube.com/watch?v=5p2rdUzBdTs

Additionally when testing to see if the damage was isolated to the turntable, there is an audible "buzz" or vibration when source material contains a low frequency sound. I believe I have isolated the noise as coming from the center dust cap but am unsure.

There does not appear to be any overt signs of damage on the rubber surrounds or where the cone attaches to the surrounds. I did remove the driver from the chassis and inspect the underside, there do not appear to be any rips or tears in the material.

Here is another audio clip indicating the buzz (for reference, the balance control was 100% to the left, the volume was @ 1.5 on the amp, and the camera was held approximately 3-4 inches from the face of the speaker): http://www.youtube.com/watch?v=r5K6O0NS-pU

I should also note that the right channel has not exhibited these symptoms as are present in the left.

Also of note, and very good reason as to why I will never again purchase speakers used over the internet, is the former owner was an obviously heavy smoker, and these things reek. 

I'm wondering if it's worthwhile to replace the single driver (if that is indeed the issue)and put in the effort to de-stink these decent entry level speakers, or consider my 150 bucks plus shipping thrown away.

I'm seriously considering just throwing these as is into the garage where the smell of motor oil and gasoline far outranks that of stale cigarette smoke. I don't really want these in my house anymore!
