need input on sub in modular home

[tattoo_Dan]

I live in a 1200 sf mobile/modualr home,it's an older model with thinner walls,etc,etc,

anyway,I have a good size living room where my HT is ,20X17,

I have a 12" Polk audio sub with 120watts,it sounds ok,but a little "boomy" sometimes,I am not here to look for a new sub/amp setup yet,but I was thinking maybe there is different parameters involved considering it's in a "mobile home".

I have a ported downward facing in the corner behind the tv sub right now,I have tried it on it's side,but I have not tried it elsewhere in the room yet.

any thoughts ?

to be honest,I really don't know exactly what a "good" sub in a HT should sound like,I have not heard any other good systems in homes,I really don't have a reference to compare,there is so much talk here about it,but I don't know what "good" should sound like ,I know what I have and what I "think" should sound good,I hope that makes sense.


it's kind of weird here,sometimes it sounds good,and sometimes it seems to "boom a lot,and in the kitchen it's too much bass,but in the lr it's not enough,

I would start with this and then look at other products.

Mobile home or modular?

Is this a mobile home or modular home? There are quite different. A modular uses very similar materials that a site built home would be made from. The difference is that some of the materials are pre-manufactured offsite and this reduces the overall cost. It's cheaper to do this way. As far as the quality of the structure, this really depends on who built it and the the care taken during the building process and the materials used. A well built modular is not much different then a site built home.
Now a mobile home is completely different. It's wheeled onto the property and titled just like an automobile. A modular is sold on the realestate market just like any other house. In fact you may have a hard time even knowing it was a modular intill you saw it on the deed. By contrast, a mobile home is usually not of the same quality of a modular or site built home, so I would have more concerns about structural issues in this case. To answer your question, the type of walls could have an impact on sound quality.

yes,there is a big difference,you are right.
it's an older thin walled "mobile" home,so yes,I am dealing with some different issues for sure,I wanted to get some different ideas and thoughts on this.

How big?

How big is your sub? You could also look at one of these:

I plan on picking up one of these for my Ultra.

ya,I might need two of the small ones or one of the big ones,

my sub enclosure,is 16X18",and the legs are spaced 16X14".

actually the smaller "gramma" would probably work "The original GRAMMA is 23" long by 15" wide "

I found a local Auralex GRAMMA dealer here,"Skip's Music" http://www.skipsmusic.com/ ,pretty cool place,they had the 15x23 GRAMMA for $47,just installed it a couple hours ago,so far sound good,I need more time to play with it.


BTW,watched "The Brave One" tonight,great movie!

The absolute biggest difference you will make to that existing sub's sound quality is add a parametric EQ, get a RS SPL meter and test tone CD. Or, use REW (freeware) with the RS SPL meter plugged into your soundcard input so you can measure your room response and correct it electronically, at least from your favorite listening position.

I second that.

Even using the measurements to help with "positionally EQing" the subwoofer will help.

Here is where you can learn more about/download REW.

If you are not using REW, yes. But if you will be using REW, you also need an output.

The Behringer Feedback Destroyer is the least expensive good one that I know of.

If you look for something cheaper, remember that it must be a parametric EQ.
