15 cab for bass-guitar, cubo?

Hi there!
i'm looking plans for build a cab for for gigs and rehearsals, i already have woofer just like this, but 86-118-08, 8ohm.
and many pieces of particleboard (don't sure it's right translate), 54cm wide. i found plans of cubo 15, but it needs 62cm-wide pieces. what can i do?
thanks!

You could build a Cubo 15 at 54 cm width, plus thickness of the particle board on both sides. It would make the Cubo 15 a 44 Hz and up cabinet. I've known quite a few people using Cubo 15 for bass-guitar with success.

Best regards

Would I have magnet out of box or in box?

That depends on the specific loudspeaker driver used and your personal taste in the matter, non of which are known to me at this point. However driver orientation is easy to try once you've build the cabinet.

I was considering the E 3015, is that ok or do I need the 3015LF?

The 3015 is a good driver for your purpose, considering that I would start with the magnet in the chamber (not visible).
