Hi, all... I'm currently running a TC-3K Dual 2Ohm on a Sundown 1500D and looking to make a change. I like the single 15" setup so I'm looking at the Havoc 15". The enclosure would be sealed, net 2.5 cubes, 1.5" mounting baffle for the sub. Looking for LSQ setup. Any of you have experience with both of the subs or how the Havoc would compare. The TC-3K hits incredibly hard down low but it's just not as "tight" as I would like and doesn't have much of a top end in my opinion. Also I'm open to other subs as well. Budget less than $400. Thanks...
