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.
