I know there has been a lot of this on these forums, but I want more info myself, and specifically for my setup.
I have a sony STR-DH700 receiver which I have used for 7.1, I have recently moved my HT to my other room, it is quite small, and after reading stuff on here, I don't think it would be big enough for 7.1.
My front speakers are PSB Stratus Bronze, is there any benefit to bi-amping these? Now, maybe it is just a marketing term, but on the back of my receiver it says I can use the surround back speakers for bi amping...but is it really bi wiring? Or can I still have 7.1 and bi-wire? Because from what I have read bi-wiring is just using 2 sets of speaker wire that plug in to the same terminals at the receiver, or am I wrong?
Or should I forget Bi-amping and just do 7.1 in a small room?
1. No need to bi-amp using the AVR.
2. I have 7.1 in a room ~13' wide x 17' long and it works well. How small is your room?
Also if your room won't accommodate a normal 7.1 configuration easily, then consider experimenting with heights or wides.
Also, FWIW a well set up 5.1 will perform better in my experience then a poorly configured 7.1 set up.
Unless bi-amping results in different gain levels to each driver than non bi-amping, I doubt there's going to be much (if any) audible difference at normal listening levels.
The only benefit of bi-wiring is to eliminate the speaker's crossover network. As mentioned this can allow the amplifier to run more efficiently.
Passive bi-amping as implemented by most AVRs does not allow removal of any speaker crossover components.
I suspect any amplifier efficiency gain from removing crossover elements is deep in the mud. There are other reasons for active bi-amping.
How does bi-wiring eliminate the crossover network? I do not follow that at all.
@krisl100: In a small, square room you may find more benefit from room treatment than cramming in extra speakers.
no. bridging essentially sums 2 channels of amp power to a single speaker.
passive biamping allows for the separation of the tweeters and woofers by removing jumpers at the speakers binding post, then adding a single amp chanel to power the woofer and another separate amp channel to power the tweeter. there is no audible benefit to passive biamping and is generally considered a waste of time, and an inefficient use of power especially for the tweeter amp channel.....as tweeters will rarely if ever use more then 20 or so watts at any given time, so having a 100 or so watt amp powering them is obviously wasteful.
bridging can have audible benefits assuming your speaker can handle the power available. the benefits comes in increased loudness potential.
Biamping is normally done using an active crossover that splits the signal to two different amplifier channels so that the highs and lows are amplified separately. If passive biamping works as you describe where the passive crossover is still used it sounds like a waste of time to me.
