My choices are limited to the following due to size constraints and the fact I can get a good discount locally. System#1) Def Tech Promonitor 80's with supercubeII @ $1450 Cdn. System#2) CANTON CD101 (formerly CD1) @ $1000 Cdn. System#3) CANTON CD101 with supercubeII @ $1480. Room is about 10x12 but opens up into the hallway. Also, the cost for me to buy the supercube is $900. Would I get more bang for buck with an HSU sub and do HSU subs integrate well with small satellite speakers? P.S. I did audition all these speakers and found them all very good for my needs. Just looking for recommedations or feedback from those of you who may have experience or knowledge with any of these products. Thanks.
