Open baffle speakers

My woofer towers are H-frame open baffle with four servo-controlled 12" drivers. There is obviously cancellation at the lowest frequencies where the backwave wraps around, but the circuitry in the amp does an excellent job compensating for this. The measured response in my 29'x17'x8' room is not without some room interactions, but considerably less so than my previous conventional subs and is the deepest, tightest, and most natural sounding bass I've ever had in my system. 

To say that open baffle subs can't create excellent bass is hogwash. Yes, you need more power and more radiating area to compensate for the backwave cancellation, but if done properly the bass is superb.

Open baffle speakers need some room to sound their best. Most of the manufacturers say 3ft to the wall behind them, but in my experience you really need more than this. I have mine set up approximately 7ft from the front wall and 4ft from the side walls. The side wall distance is less critical since the backwave cancellation helps reduce side wall interactions. 

As long as I have the space for them, I wouldn't consider switching back to box speakers after living with the speakers I have now. 

@mijostyn - I have not had that experience. My OB woofers have smoother in-room response than I have ever been able to achieve with conventional box subs. I suspect this is because they don’t excite the side to side room modes as much because of the radiation pattern.

My response at the listening position is fairly flat, ultimately rolling off in the upper teens.
