Based on the original BBC LS3/5a specification, Jeff Bagby's goal was to take this specification to the next level by incorporating today's advanced loudspeaker technology and computer modeling techniques...hence the name "Continuum".
The monitor is just slightly larger than the original LS3/5a (8"W x 12.5" H x 8.5" D), but offers significantly greater performance in terms of overall SPL, lower distortion, and bass output.
The 5.25" woofers have a large motor, cast frame, and a mica/carbon filled poly cone. The Continuum has better bass extension capability and higher output capability than the original LS3/5a.
The Continuum remains true to the original BBC specification in the implementation of what the BBC called "Acoustic Scaling," often referred to as the "BBC Diip."
