Cubo 18

To celebrate the 40 year anniversary of the Rubics Cube:

@Kiz77: That's an easy one, the LF18G401 wins by 3 dB (that's an insiders joke about n0).

Hi Cubo

i want to ask if the P Audio c18 650el can work well on cubo 18 cab?

Thanks in advance

And two more Cubos enter the world.

This will bring me up to four total and should give me a nice system for medium size parties. I built the dual 12 + 1.5 last month and two Cubos were not nearly enough to keep up.

...

hi, whats the recomeneded HPF & slope for cubo extended pd1850 loaded with magnet inside the chamber? does the polarity need to be reversed? i find it plays better with polarity as normal

@Tweeter_Box: With the magnet inside the chamber I would say 35 - 40 Hz, 12 - 24 dB/ octave. What sounds best, is best untill proven otherwise. To your previous 2 questions I believe the answer were yes and yes, can't remember exactly what questions they are tho.

@Crossed: that's good news, you might be able to use 6 Cubo's for two 2 x 12" tops (/ 1.5") if it's bass-heavy music. The again, if I had your current setup I wouldn't need my system to grow

@PrettyHard: It would work but I don't think it would give the deepest bass possible and need a bit of power to get going Xmax-wise everything is very OK. Someone from the Philipines has build two and since he responded quite happy I asume it went well.

hello , which type (extended or classic) is better for RCF LF18G401 and with magnet inside or outside thanks a lot ! greetings from slovakia !

Hi,

I would start with Cubo 18 Extended, with the magnet outside. I like the LF18G401 as it's pretty efficient (3% +). If you want to maximise on efficiency you can put it with the magnet inside the chamber but with the magnet outside would be my initial bet.
