what do you mean by cracked speaker...they can have tears in the cones the voice coils can be blown or dropped but I have never heard anything about a cracked speaker...

Re: How to tell if you have a cracked speaker

you can actually see tears in the cone but other that that any issues with a speaker would have to be somethig you could hear...if it sounds fine and looks fine then it's fine...

Well the bass is really flabby and it is breaking up more then it should at the volume its at. its a peavey valve king 50 watt 112.

Your voice coil or former might be outta wack. If you push (gently, with the palm of your hand) the cone in and you hear a scraping sound or feel resistance the former is warped and it's time for a new speaker.

Also measure the DC resistance...it should read a tad lower than the rated impedance. If you get a number that's way off you've got a short.

But as TGWIF said...maybe it's just a crappy speaker.:27:

If the VC is not out of alignment and rubbing before you do the 'push test', it will be when you're done. If it doesn't sound good, distorts easily, or has raspy overtones, assume you have a blown speaker and act accordingly.
 
Re: How to tell if you have a cracked speaker

I had a problem with a vintage 15" Jensen from an old Gemini VI amp: it was giving a fluttering sound with certain bass frequencies but I couldn't find any obvious tears. I noticed that if I put pressure on the "spider" (the flexible, ribbed connection and cover between the rear of the cone and the coil/magnet housing) at a certain place, the fluttering stopped. So, as a temp fix, I taped some springy wire pushing a small piece of foam into this location. This took care of the problem. I couldn't find a tear in the spider, but it's hard to see around the metal framework. Maybe there's a weak spot that has caused some sort of resonant vibration to show up... dunno.
