I could really use the assistance of the Polk community here about the set up of my Onkyo TX-SR705 with my LSI25's.

I know that I could really benefit from a separate powerful amp but this is what I have now. I set the Onkyo to 4ohm's - how else should the receiver and speakers be set? I will be getting a LSIc center speaker hopefully soon as well and I do have a separate Klipsch sub now.

If anyone else knows something about this receiver and how I should set it up with these speakers would be greatly appreciated Thank you Dave

    Most are going to tell you to get separate amps to power those speakers, as your receiver will be limited on its output when set to 4 ohm mode.

    Those speakers deserve/demand a lot of power (full range).

    Thank you for the reply - I don't have unlimited cash at the moment. In the future, I plan to get a separate amp. This is the situation I have presently. The system still sounds great and I'm trying to get the most out of them in the present state

    Your AVR should be set to "4 ohms" as you already have it, and that would be the only precaution you could take........ excpet for being careful with the VOLUME The louder you crank it with the 706 running a full compliment of LSi's the better chance you have of damaging something. Onkyo's run hot as it is, and running LSi's without an external amp will turn that thing into a space heater. I love Onk's and have one myself, but the sooner you could get an amp to run those LSi's the better off you will be. you can pick up a used 3 or 5 channel amp for around $500 (or less), and there are usually some for sale on in the For Sale section of the forum or you can check Ebay/Craigslist too. Good luck and welcome to Club Polk, all be it a month late, lol.

    Let's be realistic, the LSI's need lots of clean power, an AVR isn't going to be able to deliver what the LSI's need.

    If you want these speakers to really sing for you, you'll need to look at an amp that will give you 300+ wpc@4ohms......

    I've been right where you are now, and if you like the LSI's now wait until you hear them with the right amp.....it's like night and day..
