- How to improve subwoofer sound? -

[MKZ]

I have tried changing IC, power cables, splitter, isolation pads. Can you guys suggest some?

[Ron Temple]

Improving your sub is a matter of getting the flattest frequency response possible in your room. Bass waves are so long that they refect back on themselves...many times causing cancellation in your seating position. Best thing to do is find out what you're getting. You need a SPL meter and some test tones, then graph out a frequency response. When you know what's what you can play with placement, phase, etc to improve things somewhat. Ultimately, you might want to go further with treatments and EQ...up to you.

You can download REW (Room EQ Wizard) over at Home Theater Shack along with the tutorial to get you started.

learnt this from mike/mcloki:

put your sub on your seat/listening position, play some bassy music. walk/crawl around and find where bass sounds best. put your sub there...

also audyssey room correction helps tame peaks...

Sub EQ perhaps, SMS-1 or Behringer.

What problems are you having with your subwoofer sound?

[McLoki]

What kind of sub, how large of a room, how is it conencted, what is it not doing that you wish it would?

I tried, 40Hz seems to be a little high on my sub.

I have limited space :(
The placement might be some issue because I got the best bass in my bathroom which is not far from sub. I think the bass trapped there and I can even feel it on my toilet seat.

Yes, I wanna try it last.
My sub has some EQ build in but I have no idea how to use it.

What problems are you having with your subwoofer sound?

I have no problem with it but I just want to improve the sub like changing speaker cables and ICs.

It is SVS SB12-Plus and my room is around 20x20x9 with full of junks. I connected with 12ft of Signal Subwoofer cable with AudioQuest splitter, powered with PS Audio Prelude and it is sitting on Isolation pads. There is nothing wrong. I just want to improve the sound.

I got more gain with the splitter but less gain with the pads. There is not much improvement on changing the Sub cable and power cable.

Have you trapped the corners yet?

Have you trapped the corners yet?

I wished I could.

Since your sub has an EQ built in then learn how to use it. That should improve things. Call SVS or read your owners manual.

+10. Everything you need to know is above ^

[MKZ]

After I got the graph how can I fix it to get flat w/o equalizer? Any other tips and tricks you want to share?

[steveinaz]

Analyze your graph, see where your peaks and valleys are and mess with level, cros-over freq, and phase until you get the smoothest/flatest transition.

[MKZ]

I did my hw and tried my best. It doesn't effect much on graph but I got more inaudible vibrates. PEQ users please share your setting.
Here is mine:

[dholmes]

Did you change the power cord on the svs?

[MKZ]

Yes.

[Ron Temple]

You've got room correction bypassed. Set it to large, medium or small and run a graph for each setting. Your best response will probably be on the large setting, but each room is different. If you still have a peak at 40hz, then you can cut it with the PEQ. It looks like you have it engaged in the picture. How's that working?

[MKZ]

I placed the woofer along the wall so I thought bypass would be the best. I'll play the room setting as you suggest anyway. Yes, PEQ helps abit on 40Hz but not completely flat out.

[Deadof_knight]

where is the sub located in reference to the front speakers........

[MKZ]

3, 4ft away from left speaker. There is hall way between them.

That doily ain't helping things either. :D

Maybe its there to attract the cat to sit on top as a dampener?:p
