If you are looking for Dual PA speakers that will give you good lows and bass, as well as handle highs and mids really well, then Dual 15" PA Speakers is the weight to go. They do weight more than a Dual 12" PA Speaker, but will give you more bass response if you do not have or use a dedicated 18" subwoofer than the dual 12" will. If you are really looking for some bass, then you should add two 18" subwoofers to your PA system. One of our technicians favorite configurations is taking a pair of SA-155T Dual 15" PA Speakers and stacking them on two Aftershock 18 powered subwoofers. You can power the Dual 15" off the satellite amplifier in the Aftershock 18 and therefore eliminate the need to tote around a stand alone amplifier.
