The original idea behind that possibility, was that Cubo 15 is supposed to be suited to almost any 15" (bass/midbass) driver out there. Low Qes/Qts driver ussually prefer a smaller chamber whilst medium Qes/Qts drivers like a bit more chamber volume.

Note that the peaks will be a bit more flat/ rounder and the low end will be extended (up till 10 Hz lower actually).
Utilizing a 40 Hz high pass (12-24 dB/octave) they could handle a bit more (1000 W a piece should do).
Personally I would make a double version with the mouth's combined with a single panel in between (it could be left away perhaps). I can post some configurations if you'd like. The commercial version will be also available as a double, yet R&D will start within 3 months orso.

The extended version simulates and measures flatter for ~70% of the drivers tested, ussually also found a nicer shaped impedance plot. The other 30% prefers the non-extended form (i.e the Delta Pro 18).
Up till now I have recommended the more complex extended Cubo 15 (with angled cuts) were needed (via mail).

Can you, please, send the plan and the extended version? kljajicb@inecco.netCubo15 wrote: Cubo 15 (= 7, gotta rename that pic ) has been in use for quite some time now and has proven itself in combat, so to speak. Playing around with different horn lengths always measured (only) a tiny improvement in flatting the frequency response whilst highly increasing the difficulty of construction (increasing the amount of angled cuts) and panels. Believe it or not, it took me a few months to come up up with this particular idea, utilising a single panel, no angled or weird cuts, not blocking the magnet vent, allowing for deep drivers, etc. The HR-sims are also quite easily matched with the (more precise configured) AkAbak sims.
