JBL Studio 620

JBL Studio 620: 2-way stand-mount loudspeaker with a 133 mm woofer

The smaller of the two stand-mount models in the Studio 6 range: a bass-reflex two-way to place on a stand or a shelf, suited to amplifiers of up to 100 W. Sold as a pair.

The 133 mm woofer has a PolyPlas cone; the treble comes from a 25 mm compression driver working through the HDI (High-Definition Imaging) waveguide. The cabinet is tuned by a port that opens on the back panel, and the handover between the two drive units takes place at 2.3 kHz.
