Product Features
Plus One® honeycomb-laminate (HCL™) woofer cones
The P660C woofer cone is exceptionally stiff and lightweight, with up to 25 percent more active surface area than a standard cone of the same size. Patented Plus One® (patent no. 7,548,631) woofer cones and long-excursion surrounds boost bass output and efficiency by two to three decibels compared with competing products.
Mount and listen however you like
The JBL® P660C has tweeter-level control. Use the simple switches to set the tweeter output level for personal listening preferences or different mounting locations.
Great audio output and frequency response
You’ll have 90W RMS and 270W peak power handling with a 94dB sensitivity rating. And you can push it to the limit. You’ll hear true JBL® sound, with nothing under- or over-emphasized. The P660C has a frequency response of 45Hz to 23kHz.
Higher SPL than ever
In addition to better sound quality, the new, proprietary, JBL®-patented woofer design offers far higher SPL (sound pressure level) and better suspension symmetry than the previous generation of products.
Higher efficiency than ever
These speakers make the best use of any amplifier by providing an optimum 2-ohm load. They use a lower-impedance voice coil than a typical speaker to extract the most power and performance possible from all amplifiers engineered to drive loads of 4 ohms or less.
Outboard crossover networks
The P660C component system networks have in-line polypropylene caps and low-insertion-loss air-core inductors. Outboard crossovers are integrated into a harness connected to each speaker model for easy installation. Oversized Direct-Connect terminals ensure perfect connectivity for bare speaker wires.
