I am hoping that someone out their familiar with Def Tech speakers can give me some advice. Before I get into my questions, I just want to say I am very happy with the speakers and love this new world of HT. I am renting all kinds of previously viewed action adventure movies just for the audio experience. I find watching movies is a major event and want to confirm my audio setup. I just purchased BP2002TL’s for the front towers, a CLR2500 for the center, and BP2X’s for the rears. I also purchased a Denon 3802 receiver and hooked up the speakers using 12-gauge speaker wire. The front speakers are set up as large and the rears are set up as small. My first question involves my audio adjustments for the subwoofer using the AVIA DVD. The DVD test tones and my sound meter indicate that at 85 DB I need to turn the knob on the back of the towers to about 25% (about 9:00). Even at 9:00 the initial sub woofer tone is a few DB's above the other speaker tones and then goes up further as the tone changes. I am concerned about an incorrect calibration since Def Tech literature suggests a setup around 12:00. Is it possible that an 8:30 to 9:00 setting is a proper configuration using the AVIA DVD? I also want to confirm that I am correctly adjusting the subwoofer for the AVIA setup using the knobs on the speaker. The reality is I cannot actually watch a DVD for a sustained period of time at the volume control I used on my receiver to calibrate the audio at 85DB. Having said that, I will be watching DVD's and DirectTivo at lower volumes and wonder if I should turn the subwoofer knob up and how much to compensate for lower volumes or is everything relative and I should be OK at 9:00 if that is what is OK at the 85DB calibrations suggested by AVIA. Second question: What will spiking the speakers to the floor actually accomplish for me? Third question: I want to maximize the most benefit from my speakers but I am a little timid to try the other wiring features proposed in their manual. It was so easy to just run speaker wires and the other methods seem to involve more complexity in the hookup's and at the receiver. I assume you change the speakers to small and need to incorporate crossovers and I am not really sure what type of wiring I need to bi wire or tri wire. Will the different hookups extend the lower range for sub's and how much? I guess my bottom line question, is will I actually be able to distinguish a difference in the wiring method or is all just psychological. If there is a noticeable difference is it a detectable by newbies or just audiophiles. Thanks for your patience and fire away if you need more information.
