Adding sub question

What I mean is that both sub's will have there own separated channel. Right and left for stereo use. That is the only way I would go for 2 sub's. All the demo's I heard with 2 Velodyne sub's were quite worse. First they are slow has a turtle and second instruments and voices become too big in proportion. I can now use my sub from 16hz till 140 hz with ease. Without Audyssey Pro I never heard a sub integrate that good as it should be. Still I would love to have an acoustic system for 2 separated sub's for stereo use.

AFAIK, AudysseyPro, used with a AVR or prepro, will not accommodate stereo (separate) subwoofer EQ. (It will set individual delays and levels for two subs.)

What hardware are you using it with?

Al, and thank you very much. Sorry if I wasn’t technically correct stating what I found in CD player manual, but it is listed the same way as the website,
Line Output Voltage: >2V, 47 Kohms. Who knows what is correct, but you have confirmed that either is too high.

Pkrbkr999, you mention the fact that the top end is harsh. Some do have excellent results with Nordost, and love them. Again, from my experience with Nordost speaker cables and interconnects, I thought the top end was always a little rough, and I was able to achieve a much smoother top end with other brands. Please understand I am not saying cables are a solution to your problem, but that they may just be a piece of the puzzle.

140 Hz is fairly high for a crossover point to subs. Bass is going to be directional to some degree at that point, which will make integrating the subs more difficult. Might want to get something that can handle time alignment at this crossover point, depending on the locations of the subs.
