new setup

bolelet1

I have a new set of speakers: RTi10 for front, Ci1 for centerFXi5 for surround and still using my yamaha rxv1400. the sound is great but since i have read in most threads, i need a separate amp to power my rti10. My question is:will a carver power amplifier w65 watts/channel do the work or should i get at least 100 wpc power amp. my yamaha has 170w x 7-ch (DIN)/ 110 x 7-ch RMS. thanks.

Caver make one of the best Amp. yes you do need atleast 200 wpc to power up those beast!!!

Those receiver power ratings are typically a bit fudged in that they typically only represent one channel driven at any one time.

65 real watts should do you just fine unless you like cranking your system to earbleed levels. The difference between a 65W and 100W amp is only ~2dB so I wouldn't hold my breathe to see much difference in that.

Another question: Does this 65 watt amplifier adds up to the receiver's wattage or does it stand on its own? I normally don't listen to loud music. I just want to listen to the full potential of these speakers. Also, I added a PSW10 sub which gives a very subtle bass esp. when listening to classical music. the only problem with this sub is that it is not magnetically shielded and it is interfering with my HDTV. I will try a PSW303 because i think a PSW12 is too much considering that I have a medium sized listening room. Also, I have noticed in most threads that they bi-wired their RTi10 and I just want to know if this a norm or just a matter of choice and how and where can I buy the wires for bi-wiring. Thanks so much for all your help.

When you use a seperate power amp, you'll use the preamp outputs on your receiver (assuming it has pre-outs) to send a line level signal to the power amp. Basically, the power sent to the speakers comes from the power amp, while the signal comes from the receiver. So, the power ratings on the receiver have not effect on what the power amp puts out.

For the sub, the RTi10's should be able to handle all the low frequencies. You shouldn't need to use a PSW10 or PSW303. Often when people use subwoofers with large front speakers like the RTi10's, they'll use a sub that can hit a lot lower, like a SVS sub. I'm not sure how much better the PSW10 or PSW303 will perform than the RTi10 in terms of low frequencies.

You should also note that with a seperate power amp, your frequency response should be more even at higher volumes. Low frequencies demand more power to be produced cleanly.

If you like what you are hearing, stay where you are a while and enjoy...

The big advantage from adding the sub is in letting it handle the LFE info for HT. If you are using your AVR for bass management (and not wiring your speakers through the sub), try programming the sub out of the loop for 2-ch music listening.

In 2-ch service your AVR will some much closer to its stated power rating than it will in 7-ch duty.

Regarding the question of whether to bi-wire or not, does it really make a difference since there is a jumper connecting the top to the lower, even if the speaker wire is conneted to only the top or the lower post. In short, will two wires connecting the top/bottom to the receiver be different than one wire in the presence of a jumper. Thanks again for any info on this matter.

For true bi-wiring, you remove the jumpers...

Have been a couple occassions after bi-wiring where members reported that adding jumpers back into the mix resulted in better sound than bi-wiring only...

Ok, then I will just leave it as it is and will just wait for my power amp to arrive to see the difference. Thanks again. BTW, I opted to keep my PSW10 and just get a longer cable so to place it farther away from my HDTV.
