Subs for coners or built-in sub inside speakers


I'm unfortunatley limited for space - I'm looking for sub that is best suited for corners or should I look deeply into speakers with built in subs like Definitive Tech BP series - I don't know of any other speakers out there with the same concept as DT - your suggestions/recommendations will be greatly appreciated....

Von Schweikert had a speaker (model 300?) w/built-in subs and Vandersteen offers the Model 5 and the Quattro. In the big to mega-buck range, AvanteGarde Horns and Audio Machina offer such models. I'm sure there are some others as well.

I had a REL stadium in a corner and couldn't have been happier with it - no directionality at all as long as it was set at the right level...
the Definitive Tech 7002, 7004, 7006 all have great built in subs you will love with home theater. The speakers are all have a very thin profile too.

I've always had difficulty blending a corner sub(s) into my systems.This is especially true for listening to music(as opposed to movies).I use Canton Karat M 70's with their sidefiring unpowered woofers in my main theater system(no sub).Despite many equipment changes,I've been happy with the speakers for 10 years! I do regret selling the Mirage OM-6 speakers that used to anchor my 2nd HT system in the basement.I've moved to smaller monitor with a corner sub.I can never get the bass quite rightThe OM-6's were so coherent with their built in ,very adjustable powered subs.
