you will need a total of 4 channels of amplification to power the LFR's...

the number of amps can vary.. if you got a single 7 channel amp, that would cover a 5.1 surround sound setup with the LFR's.


or, you could get a 5 channel amp and a large 2 channel amp to drive the front speakers on the LRF's...


however, if you are going to have muptiple amps powering the LFR's they need to have the same Gain. which, is one of the specifications that is usually clearly stated in the manual for almost all amps.


for my 5.1 system with. LFR's, i have 3 amps. two 2 channel amps and a 3 channel amp.
