Cubo215 ready for some action!

If you mount the drivers like i do, the reverse the polarity.
You can do both, but normal dont sound that good.

The plans is not on this site. Only the Cubo and Cubo extended

Ask Mr. Cubo for this version

When using those speakers built in a double cab, do they need to be stood upright as in your pics, or can they be lain sideways? Or does it not matter either way?

See the latest graph on this page: www.freespeakerplans.com/cubo-12.html Stood upright emphasis kick, lain sideways emphasis lower frequencies.

Also stood upright the higher driver experiences slightly different boundary loading and is likely to fail just a tad before the lower driver does. Off course that's not a problem if your not pushing the drivers to the maximum constantly.

Best regards

Cubo
