    The only real difference between the LSi15 and the LSi9 is the physical size, meaning you can fit at least 15 pairs of LSi9 (so 30 total speakers) in a circular arrangement around you. Naturally, each pair will be no further than 3ft from your ears at any point.

    And you should have no problem running them all simultaneously off your current AVR.

    They do both say Polk on them -- I think. So there's that.

    Given how nice the LSi7 sounds, and most feel better than the LSi9, I have wondered how a tower with similar configuration as the LSi7 (M-T) and with the subwoofer like the 15 and 25 would have been. Would it have had the sweetness of the 7 and with bass extension? I imagine that Polk must have prototyped it. Could have been the LSi13... Make that LSi11 or 12 because 13 is unlucky in some markets.

    The LSi9 and LSi15 are from the same line and share drivers and Tweeters. The crossovers however are different.

    The LSi15's have an additional bass driver whereas the LSi9 does not. The LSi9 relies on the mid bass drivers to produce the bass whereas the LSi15's are crossed over higher and sends the bass frequencies to the Lower Bass driver.

    They do not sound the same except the LSi15 has more bass. The LSi9's have a muddy sound if you side by side them with the LSi15. The LSi15 is a much better sounding speaker.

    If you do a side by side with the LSi7 which is the smaller single driver speaker that has a keyhole on the Power port for wall mounting, also sounds much more like the LSi15.

    The better sounding bookshelf speaker to me was the LSi7. It had the clarity of the Lsi15 without the muddy sound of the LSi9. If you use the LSi9 with a small setting and cross it over at 80-100 hz it sounds much better and then add a subwoofer. Then the LSi9 actually sounds damn wonderful.

    I owned the entire LSi line except the LSi25 which I have a lot of experience with as I use to Install them. They are some damn good sounding speakers when properly setup. They had smoother sounding bass and deeper due to being a powered tower with a powered bass driver built in.
