Klipsch RP500MB II Reference Premier 5.25" Monitor/Bookshelf Black Lose yourself in sound Klipsch's new RP500MB II bookshelf speakers deliver detailed sound while taking up little room. The woofer and tweeter were slightly reworked for noticeable improvements over the previous generation. Their eye-catching copper-colored woofers and contemporary design make them a fun addition to any room. The versatility of the RP500MB II cannot be overstated. You can rock a two-channel music setup with a pair of them. Alternatively, they can be used as front- or surround-channel speakers in a home theatre system. In either case, their crisp, dynamic sound immerses you in whatever they're playing. A refined horn and updated tweeter The vented housing of the 1" LTS (Linear Travel Suspension) tweeter helps to reduce standing waves, which can degrade sound quality. It's housed in a Tractrix horn with a widened mouth for improved soundstaging and directivity. This means a larger overall "sweet spot" and better imaging within that sweet spot. To keep the highs smooth and non-fatiguing, the horn has a soft silicone face and a unique phase plug. Under-the-hood driver upgrades Metallic drivers aren't new to Klipsch speakers, but the company has improved the motor structures behind the 500M II's cone significantly. The 5-1/4" woofer in each speaker has a 70% larger voice coil for improved control, speed, and accuracy. The woofers also have new aluminium shorting rings, which help to reduce distortion and allow the drivers to handle more power. A ported cabinet for deeper bass A rear-firing Tractrix port in each cabinet helps to deepen the bass response of each speaker. The horn shape of the port encourages more efficient airflow into and out of the cabinet, reducing port noise and low-frequency distortion. Because these speakers have a ported cabinet, they should not be placed against a wall. Their bass response will be grateful.
