got in touch with cubo a couple days ago and looks like i will be building an extended cubo15 for the Dayton Audio PA380-8 15" Pro Woofer. should be delivered on friday. hope i can get started on friday too. ill keep you guys updated and will upload pics as i go.

waiting for parts. and will be heading to the hardware to pick up plywood. raining way too much today, most likely wont be doing much.

Do you mean you want the Solidworks file that contains the 15" ?

Nice driver!

Hiya cubo, or anyone else with more knowledge than me! I've managed to chuck together one cabinet so far, and looking at cheaper drivers to put in.. Was looking at Fane 15-500's. Like you specified they have an EPB of over 100, with FS=35 and Qts =0.34 Would these drivers be good for my price range? (looking for 2 drivers for around 150) Thanks alot!

Could you link to the driver you're aiming at? Having a look on the world wide web shows several different 15-500's having as much as 3 kg weight difference between them. Even the one on the Fane website whiich I would guess a 2.5" instead of 3" VC.

Anyway, the 15-600LF seems to be within your budget as well. For that budget the 15-600LF seems your best bet.

It's a mystery for me were the extra 15 oz. of magnet went but let's assume it's either the above or somewhere else well spended.

Best regards

Hey cubo,
the 600lf i saw had a lower x-max and EPB so i figured the 500 would be better? Is this right?
These are the specifications I went on - ( www.fane-international.com/image ... t_Cat_(web ).pdf)

FS Hz 37 Hz
RE Ohms 6.2 £
Qms 8.4
Qes 0.4
Qts 0.38
Vas Litres 205
Vd Litres 0.394
CMS mm/N 0.197
BL T/m 18.38
Mms grms 93.7
Xmax mm 5.5
Sd cm2 856.33
EfÄ ciency % 2.5

EIA 426A Power 600 w
Program Power 1200
Peak Power 6dB Crest Factor 2400
Frequency Range -3dB 38 Hz - 3.5 KHz
Sensitivity 1w - 1m 98 dB
Magnet Weight 95 oz
Magnetic Gap Depth 0.39” / 10 mm
Flux Density (Tesla) 0.98
Coil Diameter 3.0” / 6.25 mm
Winding Length 0.70” / 18 mm
Coil Material Copper
Former Material Fiberglass

Thanks for the quick reply

Both drivers have the same gap depth and winding depth (Hg and Hvc), so that can't be it.

The Qts on the 15-500 is lower so one would aspect the magnet to be heavier but it's lighter. The BL on the 15-600LF is slightly higher but as the Qts is also higher and the winding depth is the same, a larger voice coil would be a possible explanation, as it would increase L in BL.

Another option would be a lower magnetization of the magnetic material though that wouldn't be very cost effective.

EBP is higher for the 15-500 but generally spoken, using a single parameter to determine the best driver isn't adviseable. That's why I list Fs, Qts, Vas and EBP, besides Xmax.

I have send an e-mail to Fane to hopefully sort it out once and for all.

Hey Cubo,
( sorry for my English ).

: I want to build a CUBO15 Extended, with EMINENCE KAPPA 15LF with 600W RMS / 8 Ohms ( Is it ok ?? )
Can you send me the exact plans of the extended model ?

: I want to add this low pass filter ( 12dB/octave 250Hz RMS power 600W CF ) model Eminence PX 250 ?

What do you think about this add ?? Because I don't have preamp with crossover.

Thank you in advance.

Could u also put the plans here for Cubo 15 extended ?
Is there a version for CUBO 12 extended ? Thanx

hi guys the Cubo 15 extended is just 1 extra panel which is added to the horn path.

If you look here www.freespeakerplans.com/cubo-15q.html just after the Cutsheet drawing there is a drawing of the panel and were to fit it.

Luckily Mr Cubo put this information in the Plans section.

Happy building.
