Bookshelf speakers with the good bass.

A pair of previously owned Platinum Audio Solo's go for about $600 (no stretching required)and have great bass accompanied by excellent performance throughout the full frequency range.
Still occasionally come up for sale on Audiogon.

Shadorne, thanks for respond. I tried to find BM15 and only
I could find is BM15A. Somehow I don't like active monitors.
Do You now by any chance where I can find BM15. Thanks

So with no mention of amplification, I feel the recommendations are a bit blind. Perhaps you've great amplification, but if not, improved will aid in structure and depth. Also, your source and cabling all influence. Massed stands?

I've listened to this speaker through a friend's electronics, CEC 2000 highly modified, custom tube DAC, custom preamp and VTL 60wpr triode monoblocks and they sang with plenty of bass in a room 30X20X12. Actually thought they sounded a bit congested in the midrange.

But, perhaps the suggestions are legitimate for your needs.

Dynaudio Acoustics BM15P is the passive model. Lot of on-line Pro sites should have it. It is an excellent speaker.
I owned a pair for about six months and used them with a Manley Stingray. Brand new pair 1100-1300 range.
