As was mentioned, the SVTRS set comes with its own amplification, and what an amplifier it has: the 6α from RBH, which is a 6-channel amp that tri-amplifies the SVTRS speakers with 1,500 continuous watts/ch going to the subwoofer section, 500 continuous watts/ch going to the midrange drivers, and 250 continuous watts/ch going to the tweeter. That adds up to 2,250 continuous watts going to each speaker, and what's more, they are being powered by Pascal amp module, which is an extremely low noise, low distortion, and highly efficient class-D amplifier technology that ensures most of the current being pulled from your outlet is being fed to the speaker, rather than lost as electronics heat output. Further increasing efficiency is the use of an active crossover which avoids the losses of a passive crossover so that much more power is converted into sound. The crossover is being handled by Marani’s top-of-the-line LPP-480F processor with an advanced FIR filter system that keeps all drivers in phase at crossover points so there is no phase rotation as is seen in passive crossovers. This allows for time-alignment and crossover slopes between drivers that isn’t possible with passive crossovers.
