I have for sale a pair of Klipsch KSB 3.1 bookshelf Speakers in good condition. I had them setup for my bedroom theater and they got very little use. In my new home there is no good place for them, since I'm not going to have a bedroom setup. I can take photos if needed, they are a black oak type finish. Asking $165.00 / OBO or possible trade for Polk CS-400 / 400i center MSRP: $ 429.00 Reviewed here Klipsch's line of Synergy Monitors is designed to deliver classic Klipsch quality at competitive price points. The Synergy Series Monitors promise powerful sound from unassuming enclosures. How is this achieved? Unlike many Klipsch speakers, each Synergy Monitor features a bass-reflex design that milks maximum low end from the woofer and cabinet. Additionally, each speaker from this series features a third-generation Tractrix horn, the hallmark of the Klipsch sound that's been wowing listeners for over 50 years.The KSB 3.1 resides at the top of the Synergy Monitor line. It's a two-way unit featuring a 1-inch neodymium magnet tweeter and an 8-inch magnetically shielded woofer. This model delivers solid all-round frequency response (45 Hz-20 kHz), though you'll still need a subwoofer if you really like to feel bass thunder. Klipsch says it's able to handle up to 100 watts of continuous power into 8 ohms; with a rated sensitivity of 94 dB, it's also perfect for use with low-powered receivers and amps.If you are simply looking for a second pair of speakers that can provide a pleasant listening experience, or function as surrounds in your home-theater set-up, check out the entry-level KSB 1.1 ($220/pair list). It'll cost you half as much, and will meet limited needs well.-- NW The Klipsch Synergy Monitors are two-way designs using horn-loaded compression drivers for high frequency reproduction and high performance bass drivers for low frequency reproduction.
