epik sub placement

kweb

The system I'm running is rti6's for front's, csi5 for the center and tc60i's for the rear's. An epik valor 15'' sealed cabinet for the sub and the onkyo tx-sr600 reciever.

The problem is sub placement. The room is in the basement and it's a finished room, drywall and drop ceiling and carpet, 12' x36' with one standard size door opening.

I think i've had this sub all over the room and I'm not getting the thump I was expecting. However, upstairs it sound's like it would rip your head off if you went downstairs. The volume at about 3/4 on the reciever and1/2 on the sub [i'm not quit sure how hard you can drive this sub without damage]. There even seems to be spots where it doesn't even seem like the sub's on, but if you put your hand on the cabinet and it's pumping. The hook up I am using is LFE from the receiver to the sub.

Any input would be greatly appreciated Thank's Ken.

I take it you're on slab. The sub is not exciting the floor...takes alot more sub to do that. I'd try running some test tones of doing a REW graph to find out what's happening. Could be many things. Since it's a long or wide room depending on orientation, the LP might be smack in the depth of a null. It's not the sub, the Valor can get you to 109-111dbs average in most rooms.

Yes it's a slab floor, but I'm not sure what you are talking about with the REW graphs. What are you referring to about the LP? I'm kind of new at this so...sorry,

Thxs,

REW = Room EQ Wizard.

It can be down loaded here.

LP = Listening position.

I agree with Ron. You don't have enough sub for your size room on a slab, especially since it's a sealed sub.

My advice is to set it as close to your seating position as possible. Also, it would help if you invested in floorstanders with some decent bass to help out the sub.
