Turbosound is a well establish Speaker Company. They make speaker for big concert just like EAW and Meyer sound. Recently, Turbosound has the blue line where you see at the guitar. Those speakers are sound fantastic. I love the build-in crossover of the subwoofer where you take the main output of your mixer into the amp, amp to sub, sub to top. This is a greater because you need only amp to drive both subwoofers and the tops. This is where they call passive 3 ways. You don’t need a separate crossover. The speaker is pretty cheap but I bit heavy. Bank for the buck. If you decide to run Bi-amp with an external crossover, I prefer the 12" than the 15". It sounds smoother. Don’t forget to check out the new EV Z4 or SX-300E. Super light and sound really good too.
