Choosing towers for a 5.1

I've searched high and low to find a specific answer to my question, but so far have had no success so I apologize if this has been answered somehwere. I'm planning to upgrade my cb-20's in my current setup of:

energy cb-20 fronts (About 4' apart. 6' in front of me)
energy cc-5 (soon to be cc-10)
energy cb-5 surrounds
B&W 10" ASW610STB subwoofer (80 Hz)
Yamaha Aventage A-720 (90wpc 20Hz-20kHz 2ch)
90% video games/ 10% music (I play games at a high volume around -15 or -10)
room is roughly 10'x12'

I'm deciding between the energy cf-50 and cf-70 floorstanding speakers because I can get them for dirt cheap through my job. My reason for wanting to upgrade to towers is that I want a fuller sound (not necessarily louder) than my cb-20 bookshelves can provide. These will hopefully be the last speakers I ever buy, so down the line, they will be moved into a main home theater area when I buy a house.

Would the two 6.5" woofers on the cf-70 provide fuller sound over the cf-50's two 5.5" woofers even though the lower frequencies would be handled by my subwoofer? Additionally, would the cf-70's have enough breathing room (speakers could be placed up to 6' apart)?

The larger drivers on the cf-70s will probably let you crossover your sub a little lower if you want which would reduce potential localization issues. As to whether they will have a fuller sound, its hard to say. The overall timbre of the speaker could change with the larger drivers which will make it sound more full, but it might also increase beaming in the upper midrange. I generally prefer larger towers myself.

Main System: SVS Ultra Towers - 15" custom ported subwoofer - SVS PB-1000 - Yamaha RX-A740 Aventage. 122dB @ 16Hz!!!
Computer System: Carnagie Acoustics CSB-1 - 12' Onkyo sealed subwoofer - Pioneer VSX-92 THX
Other speakers owned or auditioned: Aperion T6 - Ascend CBM-170 - Energy RC-10 - Wharfdale 10.1 - Arx A1b

I would suggest a better subwoofer instead.

Since you have a good a subwoofer either one will do just fine, your probably only pushing maybe 5 watts through your towers, if that! This whole obsession with watts is just hog wash, unless your doing live sound 100 watts, for your mains, is more than enough for %90 of us.
