I have been happy with the sound. (Rooms about 13 x 12 ? with a large arched opening at one end/door sized arch at other).
I bought Definitive Tech’s. (first thing I researched, back when I didn’t even understand what Frequency response related to)

ProCenter C2: Freq RL 45 Hz-30 kHz 4-8 ohm outputs Rec. Assoc Amplication: 10-200 watts
Drivers: Two 5 1/4" cast basket high resolution, high power, bass-midrange drivers with mineral filled polypropylene cones, butyl rubber surrounds and dust caps, and one 1" ferrofluid-dampened pure aluminum dome tweeter. EFF: 91 dB
ProSub 200TL: Freq: 18 Hz-150 Hz Builtin: 250 watts RMS
Driver: One high-definition 12" driver with polymer cone.
HP Xover: 6 dB/octave speaker level at 80 Hz
LP Xover: 24 dB/octave continuously adjustable variable (40-150 Hz)
Inputs: Low-Level: Gold plated RCA left, right and direct LFE in Speaker Level Inputs: 5 way gold plated binding posts left and right channel.
Outputs: Speaker Level Outputs: 5 way gold plated binding posts left and right channel.
My Front’s and surrounds:
ProMonitor 100: Freq: 50 Hz-30 kHz 4-8 ohm outputs Rec. Assoc Amplication: 10-175 watts
Drivers: 5 1/4" cast basket bass-midrange driver, 1" pure aluminum dome tweeter, blended with complex, phase coherent Linkwitz-Riley crossover.
Eff:: 90 dB

As a general rule of thumb, bigger speakers can handle power better. I think that’s part of my problem, I want to know what larger towers would sound like. I should look at the towers in Def Tech.
as their line is considered interchangeable as to voicing, (I believe).

Right now, I have to tear away from my comfort zone,,,and sniff sniff/cough cough, catch up on some major work thats piling up. I cut and pasted specs should have condensed them but have to run.
