I have a pair of Polk RTI A9's that I've been trying to break in. They have about 72 hours on them, but I still feel they are lacking bass.
My setup includes an Onkyo TX-NR5007 with an Aragon 8008x3 external amplifier for the front three channels. I have them all bi-wired for what it's worth.
I have been testing some bass tests and cannot seem to get strong bass from them, especially considering the specs.
I also have two PSW505 subwoofers and two buttkickers running at over 1000w each, but have them all turned off for the moment by running Direct mode on the receiver.
I've been testing this in Direct and Pure Direct modes with no EQ. Speakers are set to full range.
Looking at the speakers, even at close to reference level, those 3x 7" drivers barely move. You can touch them and they are not *trying* to push your fingers off. They are running, however, just not as I expected.
Any one else running with the A9's and feel they lack bass? Maybe I'm just a bass freak or it's just the acoustics in my large 1500 sq. ft. room with 11' ceilings???
I also have an Acurus 200x3 that I was planning on selling, but may attempt a bi-amp setup. I doubt this will work as sensitivity will likely be an issue for bi-amping. The 200x3 is 1.1V for full output while the 8008x3 is 1.68V. As these are both 200W amps, would I see any benefit to bi-amping (could it even be done?) or is the 8008x3 plenty of power? This would give the lower woofers 200W each while midrange and tweeter get another 200 (overkill!).
On a side note, is the higher sensitivity of the 8008x3 a problem for the Onkyo?
