Klipsch Reference Premiere RP 600M II Bookshelf speakers Ebony

Immersive sound from bookshelf speakers

The RP-600M II bookshelf speakers offer incredible performance
for their price. They provide detailed mids and highs and can dish
out surprisingly articulate bass for a bookshelf speaker. The
company reworked the woofer and tweeter to give them a leg up
on the previous generation

These versatile speakers serve many roles well. You can use
a pair of them as your main speakers in a two-channel stereo setup.
Or you can use them as front- or surround-channel speakers in a
home theater system. No matter what they’re doing, they’ll serve up
detailed sound

Smooth, articulate highs

The 1″ LTS (Linear Travel Suspension) tweeter features a
vented housing to reduce standing waves that can compromise
sound quality. The hallmark Tractrix® horn it’s housed in has a
widened mouth for better soundstaging and directivity.
That means a wider “sweet spot” overall and better imaging
within that sweet spot. The horn also sports a soft
silicone face and a unique phase plug to keep the highs smooth and
non-fatiguing. 

Under-the-hood driver upgrades

Metallic drivers aren’t anything new for Klipsch speakers,
but the company has made significant improvements to the motor
structures behind the 600M II’s cone. Each speaker’s 6-1/2″
woofer uses a 70% larger voice coil for greater control, speed,
and accuracy. The woofers also have new aluminum shorting
rings that help reduce distortion and let the drivers handle
some extra power. 

A ported cabinet for deeper bass

The cabinets have a rear-firing Tractrix port that
helps deepen each speaker’s bass response. The port’s horn
shape promotes more efficient airflow in and out of the cabinet,
minimizing port noise and low-frequency distortion.

Since these speakers use a ported cabinet, you
don’t want to place them up against a wall. Instead, I
recommend giving the speakers some “breathing room” by
pulling them away from your wall a little. Their bass response
will thank you.
