    Passive Bi-amp with 1075

    Hi
    I have spent a few hours searching the forum on this topic and have a few questions that I cant seem to find answers for. I am probably 50/50 2ch music/movies, and have a 1056. As such I have been advised not to go with a more powerfull stereo amp due to the mismatch in power across the front 3 speakers. I have the possiblity of getting a second hand 1075 and was thinking of doing the passive bi-amp setup with the spare ch driving the center. From searching other threads it seems as though with the speakers I have this is a worthwhile exercise, however does this also have the same effect of a mismatch in power across the front speakers ? Or is it not really an issue ?

    Thanks

    Steve

      What speakers do you have? I have the 1075 with 3x B&W 703, and now passively bi-amp L/R because this brought a big improvement, with the center just normal amplified. What I now know for sure, 1075 can benefit from a passive bi-amp configuration. This may depend on the speakers though.

              Steve,

              Over the weekend I picked up my Whatmough Performance series, P32 mains, P7 centre, Pfx rears, Hurricane sub etc. When I get a chance I'll compare bi-wiring it with my RB-1080 vs Bi-amping it with my RMB-1075, at this stage it is my intention to use the RB-1080 for my mains and RMB-1075 for the surrounds in a 6.1 system ie. the RMB-1075 running the 3 pfx rears and bi-amping the P7 centre with the remaining two channels of the RMB-1075.

              In terms of mismatch of amplification, I do not notice any issues between the RB-1080 and RMB-1075, can't really comment on your receivers built in amplifiers though but couldn't see it being an issue. If 2 ch music is the main reason for the upgrade I'd probably opt for the RB-1070 over the RMB-1075 if I couldn't justify a new RB-1080.

                  Well I got the second hand 1075 and have hooked it up using just the front L&R at the moment - its definetly a step up from using the amps in the 1056 !!!

                      To Biamp or not to Biamp
                      by DrJRapp
                      I'm having thoughts about upgrading my system and want some advice on which direction to proceed. Currently I have a RMB1075 driving the fronts center and side surrounds of a 7.1 system with a RB1050 driving the rears. I have contemplated two different possibilities. The first is to change the 1050...

                      Biamp 603s1
                      by Hakka69
                      I have a pair of 603s1 mains, I would like to experiment with passive biamping. I have Rotel RB-1070 and RMB-1075 amps.

                      The 603 series 1 have a passive bass driver, unlike the later models which are powered. They have a 3khz crossover, there are 2 pairs of speaker connectors on the back,...

                      Stick to RSX1065 or go to 1055/1075 separates?
                      by BleakShore
                      I guess I'd like to hear/learn advices/experiences from those who have gone this route.

                      That is, stick with the RSX1066, or exchange it for the RSX1055/RMB1075 combo? I bought it from Myer-Emco so I can do the exchange with no penalty.

                      The reason I'm contemplating this...

                      RSP-1098/RMB-1075 Biamp Question
                      by gostan
                      If I were to biamp my center channel would I run a separate connection from Center I pre-out and Center 2 pre-out of the 1098 to two of the amplifiers of the 1075, or would I simply have to split the Center 1 pre-out? I will not be using an external cross-over.
