Speaker Bass Reduction

I'd recommend first trying to relocate your speakers further away from any back or side walls. I would suggest a minimum of 5 or 6 ft out from the back wall and at least 3 feet in from the side-wall as a rough starting point.

On the other hand, it could also be your speaker cables. The Audience Au24 speaker cables are excellent at removing a very common time-smear and bloated bass and often times replacing the bloat and excess with some excellent deep, tight, well-defined, and extended bass.

Audience-av.com will set you up with a dealer who should allow you a 30 to 60 evaluation in your home so you have nothing to lose if they don't do the trick.

-IMO

Strictly speaking that doesn't reduce bass. Move the speakers around horizontally and vertically, try them against other walls. Try putting reflective material in the corners of your room. If all else failes get some high pass filters

Strictly speaking, Mfkeleher should have qualified his statement above by concluding that he is sharing his opinion rather than mislead the reader to think what he says is fact.

Perhaps his experience is difference than mine when dealing with this issue. But he should at least know that there are a number of ways to skin this cat.

-IMO (I know I'm right, otherwise I'd change my opinion)

Surely bunging the ports with something solid is going to turn a ported design into a sealed (infinite baffle) design, which could mess up the crossover design and throw off the whole frequency response.

I'm with stehno .. distance from rear walls helps, as can speaker wire.
