Blown Out Mesa Boogie Powerhouse 4x10 Cab ?

Discussion in 'Amps and Cabs [BG]' started by SamuelPaulBass, Jul 21, 2017.


  1. I recently picked up a Mesa Boogie Powerhouse 4x10 from a pawn shop for 300 bucks out the door. I also just purchased a used SVT 3 PRO for $250 from the old Facebook Marketplace today since I am upgrading from an Ashdown Electric Blue 180. It just can not cut through when I am placed next to my drummer (he plays very softly, yet still I couldn't hear myself). The top left speaker has a very subtle rattle to it. Almost sounds like there is something rattling around in it. When I increase the bass it gets worse.

    My thought is that it is the voice coil within the speaker, but I would like to hear some other opinions as well. When I press on the speaker no scraping or scratching occurs.

    Thanks so much in advance!
     
  2. Have you tried the SVT through another cab? And have you tried another amp with the cab? It could be either one, not necessarily just the cabinet.
     
  3. I put my ear right up to the speaker and it only comes out of that speaker. All the rest sound fine. I would come out of all the speakers if it were the amp.

    Have you already tried removing that speaker to inspect the back side? If not, you should. Problem might be a wire or some other debres touching the cone on the back side.

    Also check the glue joint between the cone and surround on both sides of the speaker, your problem might be a small area of that joint that has came loose and simply needs to be re-glued.

    Multi driver cabinets can be tricksie. The one that you think is causing the trouble often is an innocent party. Did you do the battery test to see if all the drivers are connected with the correct polarity?
     
  7. I did manage to get a new replacement speaker for 60 bucks and got the old one out. They do put adhesive on the speaker to seal it in place. THe speaker was the culprit. It was just annoying but it wasn't fully blown. Just real rattly. Thanks everyone for your input!
