Subwoofer Choice

Thanks everyone. I have three questions though.

1. Is the high pass filter of good quality in the Velodyne?

2. Can the Velodyne be hooked up in the same way as the REL by running speaker level signal from the amp to the sub?

3. Of the options offered by the Velodyne, which way would you recommend connecting for blending well with Harbeth M30's which extend to about 50Hz?

Thank you Bob. Can you explain why the 10" sub would not be appropriate with the Harbeth M30's? My room is only 10'X14' with a ceiling height of about 7'. Or is it unrelated to room size?

Thanks Bob.

Is the Velodyne software compatible with Macintosh computers, or only Windows based systems?

Also, I read somewhere that the newest version of the Velodyne software does not permit crossovers lower than 40Hz. Is this true?

Does a separate device come with the subwoofer? Or is it built into the sub? When I checked Velodyne's web site, the instructions for downloading software updates referenced the need for a windows based computer. I wouldn't be purchasing the stand alone devise.
