I set the speakers as small, otherwise subwoofer wont sound, and the crossover set at 80hz. I didnt run the audissey since it is a 2.1 setupyoda13 said:
Best Amplifier for my Polk TSI500
Hello,
I'd like to crank up more sound from my pair of Polk TSI500.
I have them amped with an onkyo Nr709 an also a Polk PSW505 sub. But altough this AVR is giving them 110Wpc, i dont feel they sound as good as they can.
I've read good reviews about the Emotiva XPA-2. But I still dont know if this is my best choice. my main concern is that this amp is rated 300W x 2, and according to specs these polk can go between 20-275W.
Would this extra power may damage the speakers anytime?
For the record, my build is just a stereo system, no center or rear speakers so far.
Thanks for your advise

I may have access to a pair of jamo s606 or jamo c805, a friend of mine is willing to trade them, do you think these are better than my polk tsi500 to be handled by the xpa-2?.... In this case, I'll leave polks as rear speakers, powered by the onkyo
I'm kind of lost here, sorry, may you illustrate me about "high amount of gain" and AVR/SSP?
I honestly think a number of folks are actually agreeing with you about questioning just how much benefit there would be to adding an amplifier.You said it yourself "they (the speaker) dont sound as good as they should" so Im taking a more direct approach....btw you guys are beating the amp issue to death.....
My suggestion, having auditioned this POLK series for my neighbor who was interested and knows I do HT install work is this....replace the tweeters with these....

this will improve your sound quality very nicely at much less cost than a new amp :T ....
Just that. The Amplifiers that use a relatively high amount of gain will sound much louder than those that do not at first. Some of this has to do with a relatively high percentage of Emotivas being used with AVR's where the gain will ensure that you will ensure peak voltage from a wide variety of AVR's as not all Preamp Stages are created equal.
My point is this I suppose. I have hooked up an XPA-2 and compared it to both my 2 Channel Amplifiers. Both have roughly twice as large of a Power Transformer and almost 3 times the amount of Filter Capacitance. However, especially with the Aragon, I was honestly shocked at much hotter (louder) it sounded at first blush. That being said, in Professional Reviews of Aragon 8008 Series, there were concerns about how well it would do when being used with some AVR's due to not using much gain and it decidedly being used more often in 2 Channel Separates rigs.
A similar thing is for many years Stereo Receivers (many still do not) and AVR's did not use the 1-100 or -xx to 0db Reference Level used today. In these days when folks would go to audition these, they would be most impressed with the ones that sounded loudest when barely turning the Volume Knob. A corollary to this is when say a majority of available power reserves are present in the first 25% of a Volume Knobs range, something has to give when going to the top of the range.
Just level match the Emotiva compared to any other Power Amplifiers or even the 709. The XPA-2 is far more powerful than the 709 so there is no question it can provide more headroom, but it really comes down to whether this added power is really needed.
First of all, thanks so much for your opinion and explanations. I really tought the idea to add an amplifier will be welcome by all of this forum. To be honest, This only has brought me more questions than answers.Jungle Jack said:I honestly think a number of folks are actually agreeing with you about questioning just how much benefit there would be to adding an amplifier.

When a separate amp is a must choice?
What kind of speakers or what specifications may tell me and amp is worth it?
When i said at first that i feel my speakers wasnt sounding as loud as they could, it's because when i reach 82 volume (it appears THX REF.) anything up from there i here some distorsion. My analysis was that maybe if the speakers can handle up to 275W, a 110w avr was only giving them at most half the power they handle. I really like things loud but clean, and i have plenty of space for this matter, but i also like to hear sometimes at low volumes and hear all the music spectrum, thats why i didnt choose Amps / speakers for dance halls, i guess they only sound good when lots of power are driving them. What are your thoughts?
Thanks again!
The Emotiva XPA-2 will do what you want. If you don't like it send it back within 30 days for a full purchase price refund.
Hey, can you provide a new link, if you still exist? TTY TYYou said it yourself "they (the speaker) dont sound as good as they should" so Im taking a more direct approach....btw you guys are beating the amp issue to death.....
