Frequency: From 40 Hz up to 110 Hz
Enclosure Type: Hybrid
Recommended Driver: Kappalite-3015lf (668.37 kB), Kappapro-15lf-2 (534.42 kB) and kappa-15lf (566.56 kB), drivers with EBP of 100 or higher; Fs (27-50 Hz), Qts (0.21 - 0.41), Vas (150 - 300 L) / (7.4 - 11.1 ft^3). Where EBP = Fs / Qts (strictly speaking it's Fs / Qes)
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.
