Re: Stand alone 215 cabinets question.As others have said up off the floor with horns above head height. Technically you'd get some low frequency coupling having them on the floor as far as bass coverage goes, but then nobody would hear anything else once bodies blocked the horns. If you need better low end, get subs. No full range box will give you the low frequency extension of real subs anyway.
