First off, I am an axiom owner, but I chose to get an SVS sub. It just got delivered and I hooked it up, calibrated and was surprised to find that it didn’t sound as great as I had hoped.

My old sub was a 175w KLH that really didn’t keep up with my Axioms, but the bass felt cleaner and punchier with the KLH than with the SVS.

The SVS rattles the walls, but I can’t really feel the “hit” in the seating area. It justs feels flat. A good example of what’s going is when I‘m watching the Fellowship of the Ring and Sauron explodes on the battlefield, that massive wave of bass is felt with my old KLH, but not with the SVS.

I am returning the SVS, so I’ll be in the market for a new sub. Am I just being punished for not getting an Axiom sub?

Any advice would be much appreciated.

Thanks!

What SVS did you get? I have an SVS PCi 20-39 and it has always performed awesome for me. I got mine back when Axiom's subs weren't nearly as outstanding as they are now.

Have you tested your room for correct placement of the sub? I've had KLH speakers in my past as well, including their subs, and the SVS makes the KLH sound like the piece of cheap gear that the KLH is.

I got the new SVS PB12-NSD. My HT requires that I put the sub up front, but I did try it in different place around the room and got the same results.

I'm worried that the room is somehow "eating" the bass. I'm not sure how that could be since the KLH worked fine, but I can't figure out why I'm not getting the sound I expect.

It is likely you are either sitting in a null or you don't have the set up correct. The SVS should eat the KLH for lunch. A call to SVS should do the trick.

1. Do you have the SVS in EXACTLY the same place as the KLH ?

2. How careful was your level setting / calibration ?

This may be the Axiom board but I think we all believe that your new SVS should significantly outperform the KLH. Shouldn't sound any louder or quieter normally (if the level setting is correct) but it should definitely outperform at the important parts of the movie.

I do have the SVS in the same place and used the Radio Shack SPL meter to calibrate (although It was my first time using it).

Curiouser and curiouser. Did you calibrate the KLH the same way, or is there a chance that it was calibrated "by ear" and in fact was running at a significantly higher level ?

Robot I am s-l-o-w-l-y learning that it takes a lot of patience and experimenting to get a subwoofer dialed in to a particular environment. For months I tweaked and fiddled and thought on several occasions I had mine sounding pretty good, I just recently moved the sub to another location within the room and the results were night and day. Seems like these big ol' honkerin' subs (your SVS included) takes a lot more tweaking to get them dialed in.

I agree with everybody else...keep tweaking and trying different locations.

Yeah, by ear.

The thing is that it doesn't sound good at all. It sounds bad. So I'd be surprised if more tweaking would make any difference. I either got a lemon or SVS just hates my theatre room.
