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