Klipsch RP600MB II Reference Premier 6.5″ Monitor/Bookshelf Black
Immersive sound from bookshelf speakers
The RP600MB II bookshelf speakers provide excellent value for money. They have detailed mids and highs and surprisingly articulate bass for a bookshelf speaker. The woofer and tweeter were redesigned to outperform the previous generation.
These versatile speakers are effective in a variety of roles. In a two-channel stereo setup, you can use a pair of them as your main speakers. Alternatively, they can be used as front- or surround-channel speakers in a home theatre system. Whatever they’re doing, they’ll provide detailed sound.
Smooth, articulate highs
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
Klipsch speakers have always used metallic drivers, but the company has made significant improvements to the motor structures behind the 600M II’s cone. The 6-1/2″ 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.
Instead, I recommend giving the speakers some “breathing room” by pulling them slightly away from the wall. Their bass response will be grateful.
