Product Summary

●Behind the John Bowers Active 1 is a simple but demanding concept: to achieve large loudspeakers performance from comparatively small enclosures. And these compact cabinets should be basically convenient in style, to integrate happily into home environments where space is at a premium.

●During the two-year research and development programme, our augmented design concept. This unique experienced group of engineers had at their disposal the most sophisticated tools and instrumentation, including in-house computer laser interferometry.

Technical highlights

●The Active 1 has three drive units: two 150mm bass drivers, high frequency transducer employing diminishing sound-source polyamide dome.

●Both bass/midrange drivers incorporate an advanced motor system with edge-wound copper ribbon on Kapton formers - giving superior transient and power-handling capabilities.

●The totally rigid enclosure is built in a laminate of particle board and bitumous pads and is critically cross-braced. The electronics are housed in an isolated compartment at the back.
