I recently upgraded my receiver to a new Denon AVR3312 which replaces a very old AVR1800. The vendor which I bought the receiver deliver and install in my home theater setup . While testing out the receiver, he commented that my subwoofer does not sound normal, and that the bass is way too "boomy" and good sub-woofers should, according to him not sound boomy at all. Frankly I never given much thought about my sub-woofer and always think the boomy sound is from the soundtrack.
Then he decided to check my sub-woofer and on opening the cover, he said my subwoofers needs replacing. He pointed out to me that the edge of the cone is no longer glued tightly and appears to have loosen ( see photo ). This is an Atlantic Tech sub which I have used for 10 years.

So does my sub-woofer needs replacing? And if so, any good ones to recommend for under USD1000/= ? What's does a good subwoofer suppose to sound like?
Thanks in advance.
