Cubo 15 - Standard or Extended?

Hi Group..

Im a brand new to the group and am taking it all in.... 1 major question I have about the Cubo 15 design

What is the advantages of the Standard or Extended design? I realise it really depends on your driver but I know little about mine other than its a 300rms 15" reclaimed from some old bins.

Which is best general design if you are unsure of driver spec.... Look forward to some feedback

Hi Bgrade, thanks for the link, very different looking driver in the spec but im sure its the same thing, just re branded and made to look better..

Still no clue to my real question, what is the advantages between Standard OR Extended.. ?? I have googled this for hours with little success.. I do think the extended will be better from a few hints I have got..

All very technical and enjoying this new interest allot.
