JBL Studio 625C

JBL Studio 625C: compact centre channel with two 133 mm woofers

The Studio 625C is the smallest centre loudspeaker in the Studio 6 range, intended for the centre channel of a home theater system. It is sold individually and takes amplifiers of up to 150 W.

There are three drive units: a 25 mm compression driver with the HDI (High-Definition Imaging) waveguide and two 133 mm PolyPlas woofers. The cabinet is closed, with no reflex port, which sets it apart from the larger Studio 665C, tuned at the rear. The crossover is set at 1.7 kHz.

Technical data
