really depends on whether you port or seal them... ported i think the Type-R would take it.... but the orion would offer louder performance with better Sq sealed then a type r would.... so what are u thinking for box... sealed or ported?
i really dont no i just bought the p12d4 and i wasnt really sure what it sounded like but i heard rumors that they were pretty good so ur saying a sealed enclosure for a orion p12d4 is louder than a p12d4 rec. ported box
