The algorithm sees that and believes that the speaker roll-off is where the downward slope of the bump is.
2) Your front woofers are disconnected or damaged and they are not producing bass. This is easy to check. Sometimes on biwired speakers the connectors on the back come loose, or there may be a disconnected wire somewhere.
Thanks for replies Chris, Nordo and everybody else. It's been a frusturating evening to say the least. I've toyed with most settings on the receiver... tried setting the fronts to large and disabling the sub, as well as bringing down the crossover for the subs to 80 and 90 Hz to see what the front speakers can do. Still, barely any, if no base at all.
I then took the surrounds (1 woofer, 1 tweeter) off the wall and replaced the front tower speakers (4 woofers, 1 tweeter) with the surrounds.... got a bit more base, but with the frequency range of the surrounds bottoming at 100 HZ, it wasn't impressive
I did notice though that the woofer bounced and vibrated a significantly more then it did on the original towers.
I then re-ran Audyssey using the small surrounds as front speakers and it set the crossover frequency for them at 90 (with sub on). I then Unplugged them, plugged the original towers back in, re-ran Audyssey with the sub on and it set the towers all the way to 250!
Does this pretty much conclude that I have defective towers?
