Subwoofer Question


I currently have a Martin Logan Balanced Force 210 sub paired with Dynaudio Contour 3.4 LE speakers and a Prima Luna HP Dialogue integrated amp.  My listening space is fairly small (listening position is about 11 feet from the speakers.  The nature of the room only allows me to place a sub in the front corners of the room near the speakers so I can really only have two subs.  I have been toying with the idea of selling the ML and replacing it with dual subs, one in each front corner.  One particular sub I have been thinking and reading about is the REL t9i.  Why am I thinking about this? No other reason than the itch to tweak but certainly also to improve.

I would greatly appreciate this board’s thoughts and insights.

Thanks,

because of a mandated poor bass listening position I finally discovered a fantastic sub(B&W DB1) that truly added the weight I was missing with every high end speaker that I’d tried. I run the main speakers full range and position the sub on the inside of the mains close to the right speaker.The one thing that is CRITICAL is the phase setting. I have 4 choices. 270 degrees is vastly superior to the other 3 in my system. The difference is dramatic and quickly selected. The DB1 properly set up is absolutely seamless..it really is and that’s with the crossover set high for most situations. Last thing. I’ve had too many speakers for my own good and each needed a particular phase setting. Go figure.
Keep the ML sub, and add two more.

The physics of low bass is each sub creates its own lumpy bass peaks and dips. Using lots of subs each one creates peaks and dips in different places, and they're smaller because with more they each put out less. The total result is much smoother, deeper and more accurate bass. 

This cannot be done with any one sub. Physically impossible.
