Step 18The sound-off
We tested all the speakers. Our reference is Deep's set of 120V active powered Yamaha's. Deep has been using his mobile dance party setup all over san francisco for the past couple years so it is a good comparison.
Our active 24V speakers measured up! I made 3 different systems all with 100W TK2050 amps. The Yamaha reference speakers have a much higher power rating, but they are also less efficient.
At full volume, all the speakers were fairly close to each other, the B212XL was a bit quieter. The Yamaha and the B212XL have notably better sound quality than the others.
In terms of power use, it was no contest. with equal volume levels, all the 3 setups with TK2050 amps used about 1/3 the power of the Yamaha setup (with an inverter).
With 1/3 the power draw, it means we don't need a car battery to power these systems. They run great on a much smaller and lighter gel cell. plus no inverter is needed.
