Hi guys new to the forum, and have a JBL SR4791X and the cabinet is pretty beat up, so i am thinking about removing the 2241H drivers and putting them in single boxes. Anyone who is familiar with this JBL cabinet knows that it is a pain to move. I was thinking about building either the cubo 18 or the sub 18, for use with these drivers. Can anyone tell me which box would be more suitable for the 2241H driver. I am looking for high SPL and low extension. Thank you.
