Subwoofer for RCF acustica

Hi everyone! I have 2 RCF acustica C3110, a speaker produces 300Wrms and 127 dB. My problem is to create a subwoofer form them. (Don't worry, when I'll have time I build midtops like MT-130). Have you got any advice?
I thought, a fane 15-500 (99dB) in the cubo 15 layout is good? or not?

Thanks!

Hi Alessio,

A Fane 15-500 in a (single) Cubo 15 Extended would be a good match for 2 x RCF C3110.

Thank you!

And for painting it, have you any advice? Is better a glossy paint or embossed paint?

I prefer Warnex, a water based polyurethane paint. You'll need about 1 kg per Cubo 15 (2 to 3 layers). Using a textured roller will give a professional finish.
