    I need a comparison please. I am wondering how the shiva-x will compare to a def tech super cube 1? The shiva x will be in a 2.5 ft3 enclosure with a PR tuned to 20hz. The shiva x will be run with a 500 watt amp. I am guessing the shiva x will have more output down low but how else do they...

    I have finally gathered all materials (sans MAL-X driver) to build a 24" cube (based on NEOdan's cutsheet). After reading tons of threads I am torn between sealed (my original plan) versus adding 2 of the EX-PR18 PRs to the box. Since I am ready to glue (all parts cut) I must decide. The deal...

This is an Acoustic Elegance AV15 (new dual spider design) with two 18" passive radiators. It is powered by a 500 watt plate amp. The subwoofer sits on 4 black chrome spikes which...
