I'm planning on getting a pair of Polk LSi25s for mains (set to large), LSi center, 2 different pairs of Lsi f/xs for 7.1 movies (1 pair will be side wall surrounds in dipole mode, other pair will be rear wall center surrounds in bipole mode), and for 5.1 SACD/DVD audio music sources a pair of LSi9s mounted on stands with tweeters at ear level angled in towards listening position in the rear corners. Also dual seperate subs for movies only, most likely will be SVSs ( LSi25s own self powerd built in subs will handle duties when listening to music).
Amplification for the Polks will be provided by each and every single solitary speaker in the system being passively biamped (by simply removing the jumper straps between the 2 sets of 5 way binding posts on each speaker and wiring each of them to a set of power amp speaker wire binding posts) with a total of 7 Harman Kardon PA2000 power amps, which is rated at 100 watts per channel of pure Harman power at 8 ohms (not sure what it is at 4 ohms though). Note that the rear wall pair of LSi f/x and the rear corner pair of Lsi9s will share the same power amps by having a speaker selector such as those available from Niles Audio switching them back and forth as duties require for either music or movies. In effect, each speaker in the set will have it's own dedicated, bridged HK PA2000 power amp of 200 watts (at 8 ohms) power driving it. Also, a dedicated, seperate pre/pro (which is still undecided at this time). Source will most likely be a Pioneer Elite 45 combination DVD audio/video and SACD player.
Opinions, comments, and suggestions welcomed, and thanks in advance.

    Drop the rear FX's and use either your proposed 9's or a pair of 7's. Use the money you save for your pre-amp. Are the H/K amp's rated for 4ohm nominal speakers?

    I don't think they are rated at 4 ohms, I just checked out their website and all the stats say @8 ohms, i'f they did 4 i would think they would say 4,
    Neither the pa-2000 or the 4000 are rated at 4 ohms,

    Faster, you are right, I also checked. However, I'm sure that they can handle it, but just to be sure, I guess that I'll have to call Harman to verify it. If they won't, then I'll have to go with something other than the LSis, as I've already bought the amps.

    Frank, I happen to already have an Adcom GFA5400 and a GFA5000. I think that seem to be just a tad bit little on the "bright" side compared to Harman Kardon.

    Well, it looks like I'm back in business, as here's the response I got from HK:


    Hello,

    The PA2000 should have no problem driving the Polk speakers.

    Hello. Can the HK PA 2000 drive 4 ohm speakers, specifically POLK LSi
    series, and particularly if each speaker is passively biamped with it's
    own PA 2000?
    Thanks in advance.
