I'm currently running two DA D612D4s sealed. I'm very happy with my low, boomy bass from rap songs, but not so happy with my punch bass from rock songs. I was thinking of getting an extra vented box for my subs and switching them in and out, but a sealed enclosure is optimal for these subs. Now, what subs would you guys recommend for pure SPL in a vented enclosure? I need two 12s that are around 600w RMS each. My mono amp is a KX1200.1. Budget doesn't really matter much, but I'm not against saving money. LOL.
By the way, put this here because the Sub forum is down.
Also, I'm open for suggestions on a 2 ohm DVC 15 at around 1000w-1200w RMS if any of you think that would be the better SPL option. I'd just like to have the extra box and sub(s) for maximum SPL. My SQ is great with my current subs.
