will this be possible with a yamaha RX-V757?

[bryantm3]

-4 polk audio RTi8 l/r speakers (two for front, two for surround)
-1 polk audio CSi5 centre channel.
-1 PSW10 subwoofer

i already have this yamaha (RX-V757) reciever hooked up to two of the left/right speakers, and hooked up to the subwoofer, and it sounds great.. will my reciever be enough to power this setup?

 

[zumbo]

Certainly. I would recommend RTi6's for the rear. Towers are not needed, unless you just want towers.

BTW, I am using towers in the rear. I got them for $100pr more than the bookshelf speakers, so this was my reason.

 

[Leprkon]

the sub doesn't draw off the receiver, unless you intentionally hooked it up that way. it has its own internal amplifier.

there should be plenty of power for the set-up you list.

If you are willing to scrap the towers in the rear, do it. Its just excessive.

Also, there are better subwoofers out there for the money. Look at Hsu, SVS, Velodyne, or Mirage/Energy(only if on sale).

well, i'd like to have just as full of a range in the back as i have in the front, since i'll be listening to 5.1 music (they're putting out the whole Genesis catalogue on 5.1 SACD!!!) but just as long as my reciever will power it. someone in another thread suggested that it may not work.

They were FOS. But, I still say RTi6's for the rear.

ah. okay. but what if i used RTi10s instead of RTi8s (for front and back)?
is there a significant difference in sound quality? cos the RTi10s are three way speakers and the others are two way. i don't know. i'm just exploring my options. i have a couple;
a) buy the centre channel and the other RTi8s; or:
b) upgrade the PSW10 and RTi8s to a PSW12 (or whatever comes after that) and upgrade the RTi8s to RTi10s, and go to full surround later.

I would opt for a different subwoofer than the PW10 or 12. Polk makes some good speakers, but I don't find their subwoofers to live up the value of their other offerings. I'll repeat the mantra you see here a lot: Hsu or SVS. The value of these subwoofers is unreal.

 

[zumbo]

With your receiver, I would recommend the 8's front, 6's rear,5 center, and spend the rest of the money to get the best sub possible. That's my personal story, and I'm sticking to it.

Yes. SVS or HSU.

 

[bryantm3]

yeah, i guess you're right (about the fronts). i looked up some posts from forums on google, and it turns out that the RTi10s and 12s actually performed poorer than the RTi8, because of the lack of midrange. i still think i'm going to get rear towers, though (yes, i'm as stubborn as hell) but also because of space (i know that sounds inverse; but i have about only 6 inches of space to mount a speaker on the wall on both sides, and we may be moving in a couple of years, so towers in the back might work out better with my situation. but then again, is there a difference in the sound between the RTi8s and the RTi6s? cos i want to try to have the most equal sound possible. but i will take your advice about the fronts, centre and sub. which sub would you recommend?

4 RTi8's and a CSi5 will definitely test your Yamaha. 4 RTi10's will roast it if you like to push your equipment. Stick with 4 RTi8's, or consider the RTi6's for the rear. I don't think people realize the power these Polks can handle (or require) when strapped.

when you say it'll test my yamaha, does that mean it'll fry the thing, or does it mean i'm using it safely, but with a lot of energy? please elabourate. cos it is a 700W reciever, it should be able to handle that.

 

[jaxvon]

It could fry your Yamaha. You'll note that when the speakers are strapped that they have a nominal impedance of 4Ohms, this means that your receiver could be trying to throw too much current at them.

 

[mike c]

test - meaning already nearing its maximum.

the 700w rating isn't really accurate. if you really want the big speakers (or play at loud levels constantly), get an additional amplifier to connect to your 757

an additional amplifier? what do these look like?

I'd be worried if you had 4 RTi10's with the RXV 4600. Your Yamaha is 100 watts per channel into 1 or 2 channels (full bandwidth and .06% thd). It's not 700 watts, especially running 7 channels at those specs. That power most likely drops to a third - per channel, if properly bench tested. The specs are at the end of the manual.

[bryantm3]

so even just running five channels is liable to fry it?
damn. where do i get an additional amplifier? this is getting complicated.

The issue is you found speakers that require a bit more power than more efficient speakers. Had you asked the same question about a set of Klipsch or Acoustechs, rated at 8 ohms and 96dB, we'd not be having this conversation.

Speakers dictate how well an amplifier will drive them to reference levels. Always be aware of the ohm rating, and the sound pressure level the speakers are rated (spl or dB). An 8 ohm, 89 dB speaker will play half as loud with the same wattage as an 8 ohm, 92dB speaker. So in essence, you've doubled the power of your receiver simply by choosing a speaker with 92dB. Find a speaker you like with a 95dB rating, and it will play 2x as loud as the speaker with the 92dB rating - with the same wattage. It's a bit more complicated than that (there's distance, room size, placement, etc...), but you get the idea.

Louder doesn't mean better, but it does mean you're receiver will play with less stress, at lower temperatures when you decide to push it.

what buckeyefan showed you. buckeyefan uses polk RTI speakers himself, so you should listen to him

hey buckeye, would he be able to get away with three units of the behringer a500 amps (not bridged and one channel not used) he might not have enough budget for that adcom amp

the a500's are rated at 2 x 230wpc at 4ohms (if he doesn't mind turning on these 3 units each time he uses them)
