totem model 1 vs. quad 11L

I currently am enjoying a pair of quad 11L speakers in my 2 channel system.

While I really like the imaging,and soundstage depth with these mini monitors, I want some speakers that have more bass extension.

Because of the location in a small listening room with a hdtv, computer, xbox 360, and playstation 3, there is no room left to put a sub anywhere. (10' x 10' spare bedroom)

If I was to step up to a better quality small monitor like a pair of totem model 1's would they have any better bass than the quads? (open to suggestions)

There is enough room to go with some small tower speakers like totem arro, hawk, or even forest.

I am trying to build a very nice system with used components and here is what I have so far.....

classe dr6 preamp (my one really nice piece)
Will vincent rebuilt st70 with kt66 tubes (35 watts per channel)
Quad 11L mini monitors
sansui tu417 tuner
denon cd/sacd player with burr brown chips
onkyo turntable

I plan on building a very nice digital audio computer very soon for primary music source.

The system is also used for t.v. sound and with the gaming systems.

Thanks,Dave
