Well, I tried putting one in the left front corner, and the other on the front wall about 5 feet from the same corner. Calibrated with 8033. Result = Yawn again...

So just for giggles, I moved them back to positions equidistant from the listening position, but now inboard of the main speakers. I haven't recalibrated with the 8033 yet, but initial impressions = WOW!

Now the rig is cooking! I have a second 8033 on the way, and I plan to run them in stereo with each channel independently equalized.

The most interesting thing is that when the audio program has no low bass, you'd never know that the subs were there at all. But when the drums kick in, now they sound like DRUMS. I put some Mickey Hart on and that big drum does sound big!

I always check phase before doing ANY listening.

My opinion is worth exactly what you're paying for it!
