Summary: Here's how I got this gem of a speaker to maximum performance: These need to be on mass loaded stands (20"-24") and well away from walls and corners. Even there I found the bass a little bit too ripe. So, I completely plugged the rear port with foam rubber but that over damped the bass response.
Summary: Needs a powerful amp (would recommend at least 200 watts @ 4 ohms) to bring out their true beauty. I discovered the meaning of the word "sound stage" with these speakers. The bass is just too good to be true , all my friends think there is a sub woofer playing also & search for it & are amazed to...
Summary: the lsi9 is a great speaker that hooked to rotel amp. RA1070c (100w per ch)i think that the polk lsi9 better then the b&w and better then a lots of very expensive bookshelves speakers. with the polk lsi9 i dont need a subwoofer at all. the bass of the polk lsi9 is very warm and punchy.
Summary: I'm using a Marantz PM7001 Stereo Integrated Amplifier. SO yes, that means I am running a system that is bang for your buck. But thats OK. I'm rivaling a neighbor with a Marsh Tube Hybrid Preamp and Marsh A200s Amplifier, and he drones on and on about my setup.
Summary: Nice wood, Deep bass for such a speaker, smooth high's, Loud and clean, One of the best sounding bookshelf speaker at any price. The bass is more than enough, you will need a sub for ultra low frequencies. Im considering a sub for watching blockbuster movies but Im in no rush with what I have.
Summary: These are astounding speakers for under $700.00 there the best. Better than the BW 804's in my opinion. They have a better lower end and the tweeter is smoother on the Lsi9.. Acoustic Sound Design is the place to get them..
