Yes 37.5W can perform like 300W, why? because of the power resistors. They are forcing more current from the amp, but not dissipating the gained wattage.
I needed to ensure a phase matched and powerful signal.
My SQ (RTA readings) increased signifigantly (from 32 to 38) by having both.
The BLT works with the ESP-2 to ensure a very defined "simulated" center channel.
