Blown bass speaker, hoping I can buy a replacement.

If you have switched speakers to make sure it's not just a blown woofer, then I'd suggest just replaceing the amp. It's odd for an amp to output treble but not bass on an output channel, and the tech time to figure this out could be more expensive than a new Phonic amp

You have a blown subwoofer. The only option is to replace the speaker, unfortunately they cannot be repaired.

Rockford is great for bass and your two way speakers. Alpine still controls the three way speakers that I would suggest for wanting the strong vocals with less bass. Too much bass bad so I would ignore most input from "audio" guys. They always over build the bass side, balance is the key.

it is completley possible that your sub has in fact blown itself out mine has some CRAZY excursion to the point ive turned down the bass on my laptop in hopes to keep it alive so order a new sub SPEAKER if the speaker works the amps FINE

Open the unit and remove one wire from one of the woofer terminals and using an ohmmeter check the resistance between the terminals. It probably should be between 6 and 16 ohms... they don't give the specs on the speaker... if it is very high or infinite resistance, the voice coil is blown and you be re-coning or buying new speaker. These are close in speakers and intended for a small room for studio listening while mixing. If the speaker is OK, then the bass amp in the cabinet has a failure... pray, as that is cheaper to repair than a speaker.

Real low bass is mostly vibration. Anything that has a "mega bass" 'enancement' is cutting corners to make up for bass-reproduction shortcomings. Speakers measuring 2-5/8' have no business reproducing real bass. Blown speakers would be silent. Torn cones from excessive volume might sound like unwanted vibration. Your vibration might be a resonance of the unit's own housing, mounting hardware or something nearby. Try moving it to another location.

These units are not economically repairable. If you like it and you think it's broken you might snag a whole new on on eBay with wise bidding.

If a speaker goes "bad" it usually can not be fixed. Speaker systems use different speakers for different tones. This sounds like the speaker used for bass is not working. Check if there is a fuse in the speaker cabinet somewhere. Also, is there bass gone on both speakers?

try turning the bass down and see if this helps the fluttering. If it does help a little most likely it is a blown speaker. Can replace at radioshack for under 20 dollars. It is hard for me to tell since i am not there to diagnose but also can you do a balace to go completely to the right with bass up and see how it sounds. now with bass up turn the balance to go to left speakers. if you hear fluttering from one side that means a speaker or speakers from the side that is fluttering need to be replaced. i hope this helps and good luck fixing this.

Hi there,
of course you can replace the bass components and the fuses.
If you are not sure if the bass driver are actually blow try to replace the fuses first. You can easily find the fuses in any electronic components shop (like Radioshack or Maplin).
If the cones are blown they can be repaired (some specialists can do that) or just contact cervin-vega for the spare if available.

Hi there, I would think that you have blown your bass drivers in the speakers. Sometime you may have a fuse which is blown in the speaker but this is not usual. Try on another speaker if you can.
