    I auditioned the 15's and the 25's next to one another and the 25's sounded much better to my ear. Then again, I really enjoy good deep bass response and the 25's blew the 15's away in that department.

    Where, at Tweeter?? You auditioned both with a fully capable amp also??

    Of course the 25's will blow the 15's away in the bass department, they come with an on board amp. Now put a nice amp on the 15's and do a demo, I would NOT say that the 25's will "blow" them away.

    I also have 2 PCU's, they will blow you away!:p

    Alot of that can be a factor of the amp they were running with. The bass the 15's put out sounds pretty bad with a bad amp. I would say they sound better than the 25's with a good amp.

    The 25's relieve some of the burdon from what you are running them with by having an amp built in for the woofer. I think setup and dialing in that separate amp is difficult though.

    I had the 25's for about 2 weeks and returned them as I could not get the bass to sound natural with the rest of the speaker. The 15's I have now sound much better than the 25's did in my environment. (then again, the amp I am using is much better than the amp built into the 25's.)

    Both the 15's and the 25's I listened to were hooked up to a McIntosh 2 channel amp (surely a quality amp by anyones standards). Again, the 25' s sounded better to me. I have not had any problems adjusting the subwoofers in the 25's to my taste, but then again, to each his or her own, right?

    like I said - I never did get the 25's dialed in correctly to the point that I returned them. I have been happy with the 15's since I got them. Must be why Polk made both speakers - now we can both be happy... :)

    Ok, back to my question.Will that Yamaha drive the lsi center and surrounds without a problem.(two channel for the 15's).I have neighbors really close in my new house and I think that the lsi 25's would be under used.

    If the yamaha is rated for speakers with 4 ohm impedence, then it should be able to handle it. If not, I would seriously doubt it could take the load of those 3 speakers.
