Deciding bewteen these 2 speakers. PSB Image 5T and 6T 5T 35-20,000 +/-3 dB 90 dB efficient (anechoic) 175 watts RMS 6T 32-20,000 +/-3 dB 91 dB efficient (anechoic) 200 watts RMS Both are ported speakers. Both have a 1 inch tweeter. The 5T has two 6.5" woofers, one from 2500 hz to 35hz with a second 6.5" woofer from 500 hz to 35 hz. The 6T is similar but has a third 6.5" driver acting from 500hz to 32hz. The speakers are similar in size and shape. They are both 8 inches wide and the 5T is 37" H. The 6T is 39" H. The 5T is about 15" deep while the 6T is 20" deep. I plan to use the speakers with a very competent BPS-400 subwoofer, but I want to be able to listen sometimes without the subwoofer. The 6T is about $250.00 CAD more expensive after taxes. Don't tell me to choose the better sounding speaker. I have listened to them both and they are very similar. I believe the 6T is noticabley more efficient and has a bit more bass. The reason I am unsure is because I am considering the 6T for its power handling, greater efficiency and more bass. Does the fact that the 6T has 3 6.5" drivers potentially make it muddier? I know, you think if I listened to both I should know, right? Well I can't remember noticing that, but realize that something like that might only become noticable after a few months of repeated listening. Do you think the above differences between the speakers COULD POTENTIALLY be worth $250.00 CAD? Again, this depends on whether you have heard them or not.
