Cubo 15": Cubo is a multi purpose, stand alone bass bin that will equal or out run a single 18" BR*, of similar size, from ~ 40 Hz and up in terms of sensitivity. Utilising a non-expensive driver such as the Eminence 3015LF, Kappa 15LF and Kappa 15LF Pro** and a cut list from a single 18 mm*** sheet (244 x 122 cm) / (8' x 4') with a single angled cut, Cubo 15" realises a cost effective, small and light weight enclosure following the KISS-principle.
Development: In 2007 the first prototype was build and tested. Cubo 15" is the 4th prototype in a line of hybrides aiming at the achievements as stated above. The measurement below shows the gain over the stated basreflex (see * for details).
Cubo 15 plans are also available in an Imperial version, plan available on request.
