I'm having a really hard time choosing between the two. I'm gonna be mounting 2 12" subs (MM2142) inside this box and power them both by a single C500.1 mono amp. I'm also not sure whether or not to get DVC or SVC. I'm thinking of sticking with the DVC incase i decide to add another sub or 2. as for the ported vs sub, i've heard subs pound in both enclosures, ported seems to have more bass but also rattles more. any advice?
