I toyed around with this idea in my system, which is very much like yours. I have the 803D's in front, 805D's in back, HTM2 Center, my sub has its own amp so we'll leave that out. I started with the RMB 1095, 5x200w. I wasn't happy with this amp alone. I ended up with an RB 1092 driving the front, and an RB 1091 monoblock running the center speaker and using two channels of the 5 channel amp for the rears,(all bi-wired.)This gave me the sound I wanted for the budget I have.
Need advice on bi-amping
Hello,
I am thinking about bi-amping my front towers. First I will list the components I currently have or will soon have in my system that will be relevant to the question.
Onkyo PR-SC 5507 Pre/Pro( on the way)
Rotel RMB-1575 (5 channel - 250w per channel)
B&W 804D towers
(second amp not yet purchased)
At the moment I am using this system as my 5.1 home theater/2-channel music setup. The rotel amp only has 5 outputs so, they are all used in this 5.1 configuration. I have the B&W 804d connected to the rotel amp with a single cable. What I am thinking about doing is purchasing another amp so I can bi-amp my towers. The onkyo processor has the option to re-assign two of the surround outputs for bi-amp ability. I would then use the rotel amp to power my front towers and buy another amp to run my center and surrounds. This will be a passive bi-amp setup because I am leaving the stock crossover network installed. What I am trying to achieve is tighter, more powerful mid bass response and more detailed highs.
If I do passive bi-amp my towers, would I gain more power and amp headroom this way? It seems like it would work as the woofer section is seperated from the mid/high. This way each section is getting a full 250w feed and not splitting it. I could be totally wrong about this. If so, somebody please explain how this works.
In your opinion, do you think this would provide an increase in sound quality? I know there are some of you out there that are running your speakers in this configuration. What are the pro's and con's of doing this? Thanks in advance.
Andy
