Mount the driver with the magnet inside the chamber for most output around 60 - 80 Hz or the highest possible crossover frequency.įootnotes: * 18Sound 18LW1400 in a 175 liter bass reflex tuned to 37 Hz. The driver mounted with the magnet visible (the magnet in the horn) typicall gives the lowest bass response and slightly better cooling of the voice coil. Qts x Vas = 100 - 120, Cubo Extended or Standard Cubo 15 plans are also available in an Imperial version, plan available on request. The measurement below shows the gain over the stated bass reflex (see * for details). Cubo 15" is the 4 th prototype in a line of hybrids aiming at the achievements as stated above. 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" realizes a cost effective, small and light weight enclosure following the KISS-principle.ĭevelopment: In 2007 the first prototype was build and tested. Where EBP = Fs / Qts (strictly speaking it's Fs / Qes)Ĭubo 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. Please advise if this is a good choice? Here are the parameters: Hope you can understand what I mean.Thank you for answering. Which speaker do you think will be better? I want to widen the frequency response a bit up and down.Ĭan I make two front skids (two pieces) slightly bent like a moon or should they be completely straight as in the design? I plan to make a Cubo Kick 15 and want to use one of those speakers Beyma 15QLEX1600Fe or OBERTON 15NXB1200 (or maybe another from OBERTON?)
Thank you for your time if you would like to help me. Plans Cubo Kick 15:ĭear Cubo I have question, - very important to me. It's advisable to use dampening material on all the walls in the rear chamber, except the baffle and without restricting air flow to the driver and reflex ports. Or visit the forum: Forum Topic Cubo Kick Cubo Kick works with a wide variety of drivers, some of which are listed above, if unsure if your driver works, send me an e-mail at questionsaboutcubo at gmail dot com. Over 10 prototypes were built to ensure a maximum output and clarity, in a minimum sized enclosure. The cut sheet fits easily from a single sheet of 122 x 244 cm, 15 mm 11-ply Baltic birch is preferred.
With the same frontal dimensions as Cubo 12, the output is high enough to use Cubo Kick in an 1:2 ratio (1.5:1 for live music). Initial measurements show it's capable of 110 - 250 Hz stand alone, a bit below 100 Hz when stacked in multiples.

The width of the cabinet can easily be modified, Cubo Kick 15 at 45 cm wide is best used in combination with 12" drivers to get the middle way, 100 - 220 Hz when used stand alone.Ĭubo Kick 12 is the smallest cabinet at 45 x 45 x 50 cm (H x W x D). Originally designed around the 18Sound 15ND930. The cut sheet fits from a single sheet of 122 x 244 cm, 18 mm 13-ply Baltic birch is preferred. On top of two Cubo 15's it will raise the minimal height for the high mid top to 180 - 190 cm, bringing it well above the crowd ears. Not only do the frontal dimensions match with Cubo 15, 18, 21 and Sub, but the output is also high enough to use Cubo Kick in a 1:2 ratio (1.5:1 for live music). Like all Cubo models, Cubo Kick is designed to offer maximum performance when used in a stand-alone operation.Ĭubo Kick 15 is the largest at 62 x 62 x 62 cm (H x W x D), aimed at 80 - 200 Hz, it has the most output in the 120 Hz area, for that well known "pressure on the chest kinda feeling".

Cubo Kick is a midbass bin to enforce the Cubo series or any other sub bass cabinet in the kick bass region.
