Cubo 15

The 15-300/8A is suitable for 40 - 100 Hz, in Cubo 15 Extended, with an average of 101 dB/W/m in most of it's working range. It's limited to a ~300 W amplifier. Great driver for 12 V PA systems or small systems, little low EBP though.
For a standard system I would advise the Eminence Kappa 15 LF or the Fane 15-600LF. For 12 V PA it's a good low budget choice.

Hi, Cubo.

Is it suitable the Eminence Kappa-15LFA for the cubo sub extended version? or which one is the first, second and third best drivers?
thanks in advance.

Yeah, the Kappa 15LF will work in Extended. To give a good top 3, budget and available or preferred brands are a necessity imho. Can I assume any available power?

Best regards

Yes, I have a Camco vortex6, 2300 watts 4 ohms.

In random order (from usspeaker) 18Sound 15LW1401, B&C 15NW100, RCF LF15G401. This is assuming that you mean to power 4 Cubo 15's of a single Vortex 6. If you wish to power a total of 2 (4 ohm) drivers, other models might be more convenient.

Hi mr Cubo

Don't know if you can help me out here, but i'm making a pretty big 12v sound system for a festival. The plan was originally to go with 6 omnitop12 (i dont know if you know this design, but it's a BFM top) combined with 12x cubo15 kappa15lfa. The tops will be powered with around 120 watts each and the cubos around 300. crossover will be around 110hz.

Would it make better sense though to go with 9 cubo15's and 3 cubo kick 15? with cubos doing <90hz and cubo kick 90-180hz

We're going to play a lot of different music, but mainly electronic and hiphop.

I think that 6 Omni 12 will probably be too much for 9 Cubo,s also the Omni top should be crossed over 125 hz. Good luck sounds like n interesting system.
