I have no LOW Frequencies

[singitloud]

RM6600 & PSW350

When doing a "Buzz & Rattle" test on the new DVE test DVD, I have no sound from my sub until around 45-40 Hz

I have it set up the POLK recommended way:

Phase is set correctly
Speaker setup in rcvr double-checked and set up correctly
Crossover on back set correctly (about 150)

Any ideas?

Not even if you’re kneeling down beside it? There’s no low frequency tone until it reaches 45Hz, well that’s a little odd have you double checked to make sure there’s no break in the cable that runs from the sub output from the AVR to the sub?

Also take the cover of the sub and press very gently on the cone gently! If you hear a scratching type of sound its more than likely the sub is damaged.

If it isn’t play the low frequencies tones again and place your hand gently on the cone with the tips of your fingers if you can feel solid movement of any kind at 20Hz well I’m at a lost for words.
