"Best in class"on by guitarguy1986
Pros Incredibly balanced sound, accurate, POWER HANDLING, efficient
Cons Footprint (deal with it... its worth it)
Summary I've owned a pair of these going on a couple years now - paired up with a 125 watt Harmon Kardon two channel receiver. These are absolutely some of the best speakers I've ever heard in their class, and are even better than some in significantly higher price ranges. Spent a lot of timing comparing speakers from other reputable companies in this price range (Polk, Infinity, Athena, Aperion, Definitive, Bose... even B&W) and the L890s clearly took the cake. I listen at moderate to high volumes and have a very discriminating ear for detail and balance, and the dynamic range and clarity of these speakers fit the bill perfectly. They're rated at down to 28 Hz, and its definitely not an exaggeration - the lows will bring down your house. Perfectly balanced mid-range, and crystal clear but not fatiguing to listen to tweeters.
The only requisite to get your moneys worth out of these babies is a high quality amp. I had them hooked up to a pioneer with a higher power rating than the HK amp I'm now using and they sounded like s*** - they're efficient speakers, but they really need to be driven by quality wattage. It's night and day depending on the amp. (And on that note, a $225 refurbished Harmon Kardon amp can't be beat).
Bottom line - you can't find any better speakers for the money.
Pros The appearance and sound.
Cons They are very heavy
Summary I purchased a pair of these speakers that retail for $1,400 from Harmon Kardon's online eBay store for $450 as refurbished / remanufactured units. There is no way that one can telll that they were ever used. The sound is absolutely incredible from these speakers.
