[QUOTE="Timber_MG, post: 234162, member: 18"] Qts is an TS parameter and good drivers can be made with low Q and high Q. Take the same motor and alter the stiffness of the spider and/or cone mass and you change the Q. System design is more important than the choice of driver only. When evaluating quality it would be more proper to look at distortion testing between similar drivers (including noise measurements) or even better, Kippel type testing. Expectations also differ. For instance a subwoofer that does a clean 20Hz is quite quiet until it's loud enough to become audible (Fletcher-Munson) whereas lesser subs flood the spectrum with hash which is audible. The lesser woofer sounds louder and draws attention to the very low frequencies at lower levels because of the distortion and noise that accompanies it. Most subwoofers are used indoors and the final system Q is a small factor compared to the room and placement. [/QUOTE]
