Onkyo TX-SR805 reciever WHat speakers?

jerryjerry1963

I bought an Onkyo TX-SR805 receiver (specs listed below). I am in the process of buying speakers for my new house. First what is the recommendation for a receiver like this as far as a nice set of in wall speakers for the surround sound and in ceiling for auxiliary rooms on the multi zone output. I have settled on the LC265 I for the front surround, LSIC for the center ( i know it is not in wall but this is the configuration I need for the center) LC65 I for the rear surround. I can only run 5.1.

Will these speakers work well with this receiver? I read that the LSIC needs a high output at 4 ohms (dont know what this means) so started wondering about the entire system as to if it would work.

Can/should I bi amp the front speakers? will this work with using my 2nd powered zone.

I am thinking of using the LC 80 I for my kitchen from zone 2 and tc60 i for the bedroom which is less critical for me. Also for the bath, 1 RC6S

Thanks in advance for the help.

the onkyo tx-sr805 is probably one of the most powerful mainstream receivers out there... A lot better than Sony and a tad better than Yamaha and Pioneer and Denon. it should be able to handle the load but you may not be able to drive the speakers extremely loud. I don't think bi-amping is necessary but to NOT bridge the power amps with the Polks as the bridged amps cannot handle four ohm loads.

Thanks for the reply. I am not sure what you mean by bridging the amps. Could you elaborate just a bit?

Some Onkyos can combine two channels of amplification into one... so two 130 watt amps combines into 260 watts. The drawback is bridged amps do not work with loads under 8-ohms.

Just keep it all on one channel per speaker and set the crossover and run a sub and you'll be ok. My 7 LSi speaker package is just fine with that AVR.

The SR805 is not bridgeable. The 875 and up are so you need not even consider it.

Maybe he meant bi-amped. Which it is capable of.

No I believe he meant bridgeable. Combining two channels for one of doubled wattage is bridging. Bi-amping would require the removal of the jumper between the binding posts. Bridging would not. The user manual is shared betwen the 805 and 875. It mentions bridging, but also states that the 805 is not capable of bridging, but of course both are for bi-amping.

From what I understand (which is still relatively little) and read in these forums, bi-amping with the same single AVR is not true bi-amping, but probably enough to separate the highs and lows to separate cables as well as provide at least some more power to each, even if not effectively doubled--to make a difference. But then I wouldn't expect the highs to require a full 130 watts as much as the lows would chew it up.
