Will this amp be plenty of power for Polk rti A9s with Polk 70s and a 25c and 505 sub?

The XPA-5 will power these speakers. It will power almost any speaker. It was certainly enough to power my Martin Logan Vistas and Sources with a Martin Logan Stage center. The sub has its own power and receives it signal from your pre amp. The 200 watt per channel is more than adequate.
254691
Yes more than enough. I run LSI 15,s and monitor 70,s as side surrounds plenty of power.

I would think so. Since they are rated at 89-90 for sensitivity and have 8 ohm impedance the Emotiva should drive them with ease. They drive my PSB Synchrony 1bs with a 2c center channel flawlessly, and those are not as sensitive as the Polks and are rated at 4-6 ohms.
254693
Absolutely. This amp will easily drive rated output to 200 WPC on each channel, all driven. It has been my experience with Polk speakers is that their load is not overly difficult to drive. With well designed and built cables, this combination should yield a system that will show little sonic change as you crank it up (sounds just as good at relatively high volumes as it does at low volumes).

I'm running Polk RTI A7s with CSI A6 center and FXI A6 rears and it's loud enough alright.

I'd recommend Polk Audio Rti A1's. Might be a little more than 200.00 though and you'll need an amp. 200.00 budget for what you want is difficult. Unless you go with something used on e-prey. I've seen the Polk A1's here on amazon priced at 215.00. Get a low cost receiver/amp from Radio Shack or here on amazon and you're in business.

I am running a Yamaha RXV-871 (similar to your Onkyo), a UPA-200,and UPA-500. I am also running large floor standing polk audio rti-a7's similar to yours. What I can tell you is that while my yamaha on its own was doing the job it was working vary hard to do so. The large speakers are vary demanding. The Emotiva amps are easily achieving that level of performance and more with little to no effort. As for weather or not it will rock your room; I haven't had the nerve to push it that far. Although I suspect the speakers will give up before the amps do!!!

My comment is that I agree that underpowered receivers or amps will easily damage your speakers. I learned the hard way when I was a teenager 25 years ago and the receivers I used then blew tweeters. Then I bought a Carver amp and felt the difference. At this time, I have Carver amps driving L/R/C/Sub Channels on my system. It is safer to have a 250RMS Watts per channel amp than a 40watt receiver. Of course if the Low Frequency Driver is damaged, obviously it was defective.

Yes this amp with those speakers is a reasonable match the inuke 3000 will push 800 watts . If you back off the limiter about 1db you'll be at 600 to 700 watts and protect the speaker as well. I run mine on two 225 watt 8 inch speakers crossed with a 50 watt tweeter (450hz and up) for my upper mids and highs and it runs very well. I personally wouldn't expect a lot of low end response from your combination but I push my speakers really hard. With an inuke 6000 on 2 15s each side crossed at 125 to 450 and another inuke 6000 on double 18 each side from 40 to 125. However this will do a football field in a very small speaker footprint. Hope this helps. Yes this amp with those speakers is a reasonable match the inuke 3000 will push 800 watts .

This should work wel for your system. The total power of my amp stated on the test sheet was 715amps. It has plenty of power. Turn off the low pass switches to the speakers and get your base from the Sub woofer! I think you will be happy!

Yes, it should work well. I have mine set up in an 11" x 17" room connectected to a 100w receiver and it fills the room with amazing sound. One of the advantages to the Polk TL250 system is that you can add individual satellite speakers to your system if your receiver has such capabilities.

I am using this amp for 2 4000 watt subs. Might be a little strong for 1 2700 watt. I also have 2 1300 watt subs powered by a 1000 D class amp that sound great. If you're only using the one sub, I recommend a 2000-3000 watt amp. Take a look at the AC3000.1D. Should be plenty of power. AND, cheaper. Hope you're his helped.

This amp should be more than enough. I have 2 polk db 12 on mine and my friend has 2 p3d2-12 on his.

If you go to the Pold audio web site, http://www.polkaudio.com/products/rtia1 , you find the recommended amp is 20-125 watrs per channel, so your amp is a little weak. I would recommend something over 50 wpc.

It would push the sub but probably not give you the complete power you need, I would suggest the brutus 2400.1 for your sub and make sure you have good power going to the amp.

This amp has plenty of power and will definately match these subs will if wired to 1 ohm load. Dual 4 ohm coils wired in parallel will yield 1 ohm.

That depends on the speakers. This amp outputs a true 1000w RMS, which is PLENTY of power for most speakers.

The answer depends on how much power is needed to drive your speakers. Unless you're running a multiple speaker set-up or full range electrostats, I doubt you'll need the extra power that comes with the 700's. I'm running a pair of Martin-Logan Motion 12's and I can make paint peel off the walls without my A-S500 even getting warm. Either way, I don't think you can go wrong with a Yamaha integrated amp.

Hi Tyrus, I think the amp is more than sufficient. Please start at low volume otherwise it may damage the speakers. I have used this amp with a couple of speakers between 300W to 500W and it performs well. Thanks and I hope this helps Fernando

I have this amp and it runs my 12" Polk audio sub. good base and punch. you do need to get the wired remote to control the input separately.

Simon Your setup should work the only problem I see is that the speakers you have may not get enough power but they should sound good, when I setup this speaker it was a pain trying to understand what type of series should they be installed in, but the polk audio has 4 leads red, black green, and white please follow the instructions very carefully and try only one speaker at a time. When this unit is connect correctly it sounds great.
