All-
1st let me just say thank you for all the kind suggestions on which sub is the right choice.
As I communicated w/ both HSU and SvS which they both (sales reps) were very professional and comment on there subs it was both great choices either way.
----- BUT -----
Talking with the wife, she just said to make sure I will to be happy, very happy, with my new sub purchase / selection.
I feel that a SUB will be one of my most expensive investments minus the front projector and plays a very important role in HT setups. So I decided to UP my costs to a better powerful sub.
After reading and researching some more, I am willing to spend about $600.00 on a sub. Maybe it's not much, but too me it’s a lot!
Let me tell you what I'm looking for.
I want BASS- I’m not a bass head, but I want my HT room wooden floor on the 2nd story shake. I want it to rattle stuff on the walls. Kind of like all the vibrations I get from my old Nissan Pathfinder

.
So I ran across these two companies of "The New Boys in Town" subs.
EPIK and eD.
I notice majority of subs are ported but growing up from high school and car audio I always felt that SEALED subs pounded harder (Pounded a good word?) then the ported setups I heard in vehicles. The only key thing I knew about sealed –vs- ported was you needed more powerful amp to push a sealed box sub then you would as for a ported setup. Now as for homes it seems ported is the way alot of subs are made.
~Now Epik (sealed) makes a 15" driver

called "Valor" that I am digging, not just because it's a 15" driver, but it's sealed. Would I be happy w/ a sealed sub or would maybe a eD A3-300 (ported) be a better choice in my setup? Thanks for your input
I know by car audio that eD makes some sweet subs. I used to own two 10" (5 years ago) that I made a custom box for that eD sent to me by E-mail. Sounded great, but I just grew out of car audio. It seems that kids love breaking into cars and I just didn't want to be a target so I got out of that scene!!
