SOLD The Polk LSi9 measures 15"H x 8 5/8"W x 15 1/4"D and weighs in at a hefty 33 pounds. In comparison to many of the other bookshelf speakers in its price range, the LSi9 is a fair bit heavier, and bigger too. However, the bigness is cleverly hidden. The front of the speaker is reasonably narrow, but there’s a lot of depth to the cabinet.

The LSi9 is a 2 1/2-way design. The bottom woofer works up to 200Hz, where it is rolled off with a second-order filter. The top woofer works in the bass region too, and then also continues up through the midrange to 2.4kHz, where it is rolled off with a second-order filter. A third-order filter is used with the tweeter, and that driver then flies off to the stratosphere. The drivers are all of high quality. Polk says that the 5 1/4" woofers are "polypropylene that has been ‘foamed’ with air. This technique serves to suppress cone resonance without adding mass." The tweeter is called a Ring Radiator. Perceptive eyes will notice that it’s actually a Vifa-sourced unit with a Polk Audio faceplate. It’s the same tweeter that’s used in Krell’s ultra-expensive $10,000 LAT-2 as well as other pricey speakers by Sonus Faber, etc. The cabinets are incredibly rigid and dense adding to the overall feeling of a high quality box with top performing drivers. These speakers also feature Polk’s signature “Power Port” to increase bass response.

This set is offered in solid 8 condition. A minor blemish on one cabinet with only the slightest signs of wear of any kind. We had a bit of a stand mount shootout. All the reviews online are accurate. These LSi9 are just superb.

I am only selling to recoup funds spent buying my dream speakers, GNP.
