To Sub or not to Sub...?

Even on recordings that hardly work my sub the "soundstage" will shrink if I turn it off. The hardest part (after finding where it works best in your room) is the crossover. Many subs have no hi-pass filter, and most that have them degrade the sound from your speakers. I run my main speakers full range and keep my sub at the lowest setting. I read in Absolute Sound that one of the reviewers uses passive in line filters made for car sterio in his tri-amped system. I think they are from Harrison Labs. Has anyone tried them? I think they are cheap, and as my speakers have a small mid-bass driver I would like to try some kind of filter that would not do more harm than good. Also, line or speaker level connection, which is better? I have read conflicting opinions on this. Is anything simple?

I wish I read my own stuff before I posted it. If you cant spell to begin with, having questionable typewriting skills does not help. But if I cant spell stereo.......

Subs were made for home theatre.Speakers are for audio.Buy the best speakers you can afford for your classical music and you'll be happier in the long run.Subs just complicate things and after you get over the love at first listen impression and compare music with sub in and sub out on a good system you will probably come to the same conclusion as I have after spending much money experimenting.Just my humble opinion of course.Good luck and may the music Gods be on your side:)

Soliloquy makes a very nice sub that is one of the few that can keep pace with magnepans. Works great with my Mg10.1 mains. It is also self powered with a high quality 150wpc amp.

Not so, there are subs meant strictly for 2 channel audio that sound awesome.
