I have a pair of Polk RTi12 and a pair of Ascend Acoustics CMT-340SE. I use a Pioneer 1019 receiver to power them.
I tried to listen to both with different kind of music and movies that I have and found them to be similar sounding.
Both speakers have the same efficiency: 90dB
Polk's driver components are:Woofer
3 - 7" Diameter Polymer Composite with Rubber surroundMidrange
2 - 5-1/4" Diameter Polymer Composite Dynamic Balance with rubber surroundTweeter
1 - 1" Diameter Silk/Polymer composite dome
Ascend's driver components are:Woofer
(2) proprietary 6.5 long throw polygel cone woofers w/phase plug, non-resonant polymer chassis, rubber surround, shieldedTweeter
(1) High-definition 27mm soft dome tweeter w/damping chamber and wide roll surround, ferrfofluid damped voice coil, wide dispersion faceplate, magnetically shielded
If cost was not an issue how should I go about zeroing in on the speakers. Polk is definitely more attractive.
