No unfortunately not, but you're free to derive them yourself. IIRC Bee on this forum posted a script as a how to in the Cubo 15 topic.
Best regards

I tried to simulate Cubo 12 in hornresp. But I think that something is wrong in my input data. Please look at my input data. What's the mistake?

my Cubo12 is pd12sb30 loaded
I tried the Cubo with an amp delivering 500w at 8Ohms per channel, filtered at 100hz (its a built in crossover that make high frequencies>100Hz go into one channel, and low frequencies<100Hz into the other channel)
Cubo12 pd loaded seem to be able to take (much?) more than one side's power...so I'm planning to get a external active crossover to connect Cubo12 to my amp in bridged mode.
How much power do you think Cubo would take to play to its best?
how careful should I be when going into bridged mode? smiley29
how dangerous is it to use Cubo12 without the recommended (40~45Hz?) lowcut (it seems that the cheap active filter I m aiming at offers a simple on/off 25hz fixed lowcut,)
my amp's specs :
OUTPUT POWER
RMS
Stereo
8 Ω per channel, stereo 500 W
4 Ω per channel, stereo 700 W
Bridged Mono
8 Ω bridge mode 1400 W
PEAK POWER
Stereo
8 Ω per channel, stereo 600 W
4 Ω per channel, stereo 1000 W
Bridged Mono
8 Ω bridge mode 2000 W

Hi martin, i dont think you can sim the cubo using hornresp, you need a more advanced sim programme like akabak.........

thanx for the advice, I'll follow it and keep on with my 500w, instead of overdriving my new toy to an early death
