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-yearresearch and development programme, our augmented design concept. This unique experienced group of engineers had at their disposal the most sophisticated tools and instrumentation, includingin-housecomputer laser interferometry.

Technical highlights

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

Both bass/midrange drivers incorporate an advanced motor system with edge-woundcopper ribbon on Kapton formers - giving superior transient andpower-handlingcapabilities.

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.
