Crossover Point

Posts: 7
I have some RtiA1s and CsiA4 on the way that I will be using for my front speakers and center. I live in a townhome, so I don't have space for anything bigger like towers. My question concerns the crossover point I should set on my Yamaha RX-V663.
The lower frequency response of the RtiA1s goes down to 50Hz, but my surrounds speakers' lower frequency response is 110Hz. Should I set the crossover point for the sub to 80Hz or something higher like 125 Hz? Will it do any damage to the surrounds if the crossover is set that low? I feel like I'll be missing out on some midrange from the RtiA1s if the crossover is set too high.
I'm new to the home audio setup, so any help would be appreciated.
Thanks.

What kind of surrounds do you have?Polk Tsi 500 Fronts
Cs20 Center
Tsi 100 sides
Rti a5 rears
Bic h100 subwoofer
Ps3 40gig
Onkyo 805!

I will be using two JBL CS400 satellites. They are the speakers I was using before buying the RTiA4s. I know they don't match the Polks, but I was more concerned with matching the fronts and center.

If your sub can go that high then you should cross it over at 120Polk Tsi 500 Fronts

I'd leave the sub at 80-90 Hz.
Surrounds are supposed to be full range in the first place. -
Not sure of what sub you are using, but here is an idea to try.....
Hook the right and left speaker output in your AVR to the right and left input on your sub.
Hook the right and left speaker output on your sub to your right and left speakers.
Hook all other speakers up as usual.
In your AVR,
set sub to off (or none)
set front speakers to large
set all other speakers to small with a 120hz crossover.
See how it sounds....
(I am really surprised the 663 only has one crossover setting - are you sure you cannot set different crossover points for each set of speakers?)Mains.............Polk LSi15 (Cherry)
Center............Polk LSiC (Crossover upgraded)
Surrounds.......Polk LSi7 (Gloss Black - wood sides removed and crossovers upgraded)
Subwoofers.....SVS 25-31 CS+ and PC+ (both 20hz tune)
Pre\Pro...........NAD T163 (Modded with LM4562 opamps)
Amplifier.........Cinepro 3k6 (6-channel, 500wpc@4ohms) -

McLoki, what would using the speaker output on the sub do? I'm new at this stuff, so any help is appreciated.
I haven't been able to find anything in the RX-V663 where the crossover can be changed for each speaker, but I'll keep looking in the manual. -
It means you would be using the crossover setting on the subwoofer, not the receiver, so the mains, connected to the subwoofer directly, would have a different crossover from the surrounds. This is frequently referred to as the "Polk method", since Polk frequently recommended it in the past (not sure about now, since they released the new range of subwoofers).SumSuperman wrote: »McLoki, what would using the speaker output on the sub do?

It is almost shocking IMO that Yamaha can sell a receiver these days for $550 MSRP with only a global crossover setting, if it is indeed true.Alea jacta est! -
What it would buy you is you would set your front speakers to large, your sub to off and your crossover to 120 to match your rear speakers.Mains.............Polk LSi15 (Cherry)

Thank you both. That makes sense. I'll give that a shot. After reading up on it, the RX-V663 does only have a global crossover setting.
