How big is your room and how far away will you sit from the front 3?

I'm looking to upgrade/update my HT and need some advice. Currently have H/K avr310 running four polk rt800's and a psw650 sub with a cheapo center channel in a 20'x20'x7' room open on one end. My plan was to purchase a Denon x5200 when they are more available here in Canada then find speakers. However, FutureShop Canada has RTiA5 on sale for $250 and RTiA7 on sale for $350. Is this too good to pass up? How would they pair with my Harmon until I can get the Denon?

Amp the A9's with a nice amplifier and you will be fine. The rest of those speakers wont really strain your AVR and you will have lots of headroom.

For the A9's spend money on a good nice high powered amp for them. I'd suggest at least 300wpc or more if you can swing it. The A9's LOVE LOVE LOVE power. The more you give them the better they sound.

Personally I am against using pro-amps in a HT enviornment (unless you have a dedicated equipment closet), however some folks have used the Crown XLS amps which run cool and the fans rarely kick on (one reason I dont like pro-amps in a home environment).

- The room dimensions are 250 * 180 inches. I'll be sitting at 180 inches from the front speakers.
- I'll be having a dedicated equipment closet
- Can you kindly recommend some amps that can best use these speakers? Do I need just a stereo amp for the A9's or 7-channel amp?

Thank you..

That opened me a whole new world for me after you suggested that Crown XLS can be used. I was thinking that amps like Emotiva, Marantz, Onkyo can be used.

- I didn't know that PRO amps can be used for HT purposes. They seem to carry a lot of watts. Won't that damage the A9's? Can anyone suggest me some models?
- Are there any similar amps that I can use for the SVS subwoofers?

I'm running my A9's with a QSC GX5 500watt PRO stereo amp.. and the sound is clean, powerful and the A9's love it.. I bought it second hand from a friend who did a fan mod on it so it runs silent.. my pc is louder than the amp is..

You can find videos on the fan mods for pro amps.. and the pro amps are much much cheaper than others..

An amp is an amp. You can even use a car amp to power them.

I own a Onkyo A-9050 Integrated Stereo Amplifier now and powering my A9's. Is that a good idea to sell it and purchase a Crown XLS 1500? Is Crown XLS 1500 a overkill? Any thoughts?

You can use pro-amps some prefer not to, others dont care.

It can be a touchy subject.

I am of the use a HT amp rather than pro amp for my speakers unless your talking DIY subs.

But the Crowns will work and some have used those or similar amps.

Like ALL things audio YMMV

HT front stage. Tsi400's, vs RTI8's, vs RTIA5's. L/C/R will be same

I'm building out my new HT and have a 120" acoustically transparent screen and will be putting the L/C/R speakers behind the screen. I plan to use the same speaker as my L/R for my center due to the feedback that this is the best option (is it?).

I'm going to Fry's this weekend; however, I'm not too hopeful I'll be able to test all three of these options there. Best Buy here is hopeless and doesn't have any Polk's on display.

I need 3 of the same speaker, and right now through the ebay Polk store I can get the RTI8's for $149 refurb and then a pair at $399 that are new. That seems like a great deal. I'll worry about my surrounds when I pick my front stage.

I hear the RTI's are better for HT and Tsi400's are better for movies. Just need to make sure the RTI/RTIA can be powered properly with my 95W Denon.

Is there a real difference between the RTI8 and RTIA5. I keep reading conflicting information around the woofer and tweeter. I don't care about appearance since they will be behind the screen.

Room: Multipurpose 14x22x9, 100% movie viewing
Equipment: Denon AVR-X2100W, no plan for amp (AVR doesn't have pre-outs)
Sub: BIC F12

Help me decide!

I have the 8's and have heard the 5's and I can't tell any difference, although I've read where the 5's were a little more mellow, but I honestly couldn't tell. I think your option of going with the 3 8's (one refurb'd) is a good one. I have the CSI5 as my center and it's pretty similar in specs to the RTI8, so you'd be saving some nice coin by going with the refurb 8 as your center. Just my .02. Good luck.

Oops, forgot to mention that my AVR is 100wpc for 2ch, and it powers the 2 8's, a csi5 and 2 RTi4's in 5.1 quite well and quite loud in a room that has similar dimensions to yours. Hope that helps.

CSIA6 Center or any other for RTiA7?

Hi

I currently using cs2 center in which i know it doesnt match and honestly i can notice that audio is quite different from the rti7s.

For $400 the csi6 i consider is way expensive for a 2ch center that match the rtia7. The csia4 are smallest version but i want 6.5" drivers. Other brand like kef and b&w has great 3-way center ch for bit more than $400

Is there any other center brand that can match closely to rti7s?

If you are considering changing speakers, go with the new PSA MTM's or Reaction Audio CX's. Changing to the A5's would be a downgrade, the A7 still has 2 7" drivers handling 80-125hz, which is still going to give you more impact and chest slam then the A5. If you ever play with test tones, bass above 125hz does not have much impact.

Most of your cheaper pro amps will not sustain their RMS power rating for more then a few seconds before throttling back. However they still should have plenty of power for a pair of 300w rms speakers like the A9. Remember you are better off having more power then not enough. Clipping is what burns up speakers due to the voltage signal changing to a square wave.
