Cubo 18

Can someone send me the plans for the Cubo 18. If possible, can these plans be modified to fit an amp plate the size of 12" X 8". I think it would be better that way instead of me trying to guess where the best spot for installing the amp plate would go. Thank you all!

If you look at the top of ithe page labeled plans. Look for cubo 18 . I'm don't think a plate camp is the way to go but you may liketo look at the Dayton one is 900 at 4ohms

Hi. I found the P.Audio C-18 ELF drivers at a reasonable price, and am thinking about building 4 cubo18s for them. Are the drivers suitable for this design?

Specs:

GENERAL SPECIFICATIONS
Nominal Impedance 8 Ω
Power 800 Watt (rms)
SPL 1W@1M average sensitivity 96 dB
Frequency Response 30Hz - 100Hz

PHYSICAL SPECIFICATIONS
Voice Coil Diameter 101.6 mm (4 inch)

THIELE/SMALL PARAMETERS
Resonance Frequency Fs 41 Hz
DC. Resistance Re 6.1 Ω
Coil Inductance Le 0.81 mH
Mechanical Q Factor Qms 6.76
Electrical Q Factor Qes 0.52
Total Q Factor Qts 0.48
BL Product BL 24.76 Tm
Effective Moving Mass Mms 198.64 g
Equivalent Cas Air-Load Vas 148.56 Liters
Effective Piston Area Sd 0.12 Sqm
Half-Space Efficiency Eff 2.01 %
Airgap Height Hag 10.0 mm
Voice Coil Height Hvc 26.0 mm
Voice Coil Overhang Xmax 8.0 mm

The C18 ELF is the a kind of driver that I would see fit Cubo Sub due to the 10.5 mm Xmax. It would also work in Cubo 18 Extended, but if you haven't got them yet, there are other drivers that I would think of first. Drivers with lower Qts, that will add more punch due to being a bit more efficient in the 60 - 100 Hz area.

Mr Cubo, just wondering if the Fane Sovereign 18-800 would be any good for the Cubo18?

That would be a good driver for Cubo 18 Extended.

Best regards

Hi Cubo, would this cabinet be any good for a JBLK151 for use with a 5 string bass rig, under a 2x10 or 4x10 box, no cross overs. Thanks in advance.
