View Full Version : Blown Polk DB651 speakers

I have a set of DB651s speakers in the front and DB651 speakers in the rear. The are running through a Pioneer HU and an Infinity Reference 4 chan amp. Both the front and rear right speakers have lost their lows, while retaining highs. Both left speakers are fine. I hooked up a known good speaker to both amp ports to rule out the amp and wiring. Same symptoms with the test speaker no lows with clear highs.

On the DB651 the capacitor lead broke so I am thinking I can re-solder it, but on the DB651s there is no visible damage.

Are either of these salvagable?

If you hooked up a known good speaker to the amp and it did the same thing than your amp is at fault.
