I got a tc sounds 18. Let me just start by saying OMFG!!! This sub is loud as hell. When I got the box it recomended ported and all I could find is vented. So thats what I got. I don't want to seal the box, but I am having some troubles getting the tight punchy bass to sound good with it. I was thinking of getting a couple 8s just to cover the punchier stuff. I'm extremely happy with the low end coming out of the 18. I was thinking of going with the SA-8 V2 D.2, but I havn't personaly heard them and in my research I've noticed they move alot of air, and I'm kinda worried their not going to have that punchyness I'm looking for. Any imput would be very appreciated. Thanx.

 

Build a custom box and tune the enclosure to 40 HZ, this will give you tighter bass.

 

thank you for responding. ive never tuned a box b4. how would i do that?

 

Get some one to design and build you a proper box.
