would this be a good start

[bass addict]

I would probably consider myself a HT nut. I am by no means an audiophile. My HT/music breakdown is about 90/10. I just finished building an amateur HT room and am looking into some acoustic treatments to improve the sq. Here is a pic of the room. Sorry for the poor quality.

Here is a pic prior to wrapping in speaker cloth so you can see the speaker layout. I am thinking about raising the center speaker.

Here is a pic of the rear of the room

Total dimensions are 11'9"x22x9'. As you can tell the fronts are pretty close to the sides of the walls. The walls are bare so they are definitely causing some echoing. I have about 300.00 to play with right now and am looking for recommendations. I am short on width so I have been hesitant about adding treatments to the side walls but it is looking like a necessary evil. The sub is eq'd with a behringer 1124p and the bass really doesn't seem that boomy.

My thinking is add two GIK 242's at the first reflection points (one on each side), one 242 in the back center (apparently they come 3 to a box), and two 244's (one in each back corner). I can add more later down the road if necessary. Does this sound like a good plan or would you recommend a different approach?

WOW, 39 views and no suggestions. I ended up emailing GIK and ordered 6 242's. 4 to be used at the first reflection point and 2 to be used behind the front speakers.

Looks like a really nice setup. Could the echoing be caused by the space behind the front speakers? How much room is there behind that wall of speakers/screen? Is this room in your basement, and did you insulate behind the drywall? You can also try cantering the tower speakers a bit more towards the listening position to reduce reflections off the walls. Don't go too much, or you'll lose the stereo effect.

Thanks for the comment. I should clarify what I mean by echo. It isn't noticable when you listen to a movie. If you talk pretty loud you can pick up a slight echo. Acoustic treatments will definitely help. To be honest when I watch a movie it sounds really good, I am just wondering if it could sound better.

Wow, sweet lookin' HT setup! I have been meaning to try some GIK and RealTraps stuff sometime. Right now I have around a grand's worth of 8th Nerve treatments and am extremely pleased. I'd suggest trying either Adapt or Response Corners in conjuction with your traps.

Thanks, I will definitely be adding some bass traps later down the road. Fortunately my room doesn't have that bad of a bass problem. Now my old house, completely different story.

The Corners aren't really bass traps, although they do (for reasons I don't quite grasp) seem to help with the bass. The main areas of improvement are midrange clarity (esp the vocal range) and treble smoothness.

A hugh improvement in reducing boominess and sound quality down low with a Tri Trap from GIK. Can't say enough good things about them, very pleased.

Bass Addict,

I see a few potential problems in this setup, e-mail me and I will be happy to advise you

If you can add another sub at the rear of the room, it would do wonders to smooth out bass response in the listening area. It doesn't have to be as big as the one upfront but you should choose one that has similar bass extension.

I guess I am confused. I am looking into adding treatments to calm down some reflections and tighten up the bass a little. Why would I want to add another sub when the fr in the room isn't that bad to begin with. Trying to eq another sub on the complete opposite end of the room would be a tall task.

In my old house the bass would change 2-3 db's if you moved as little as 2-3 feet from the listening position. This new room is pretty even across the listening positions. The only really noticable difference is in the very back of the room which is behind the listening positions.

One of the things that dual subs CAN do, if properly placed, is smooth out the FR and yield a more encompassing soudfield.

I'd agree though that with a limited budget, dealing with the room will give you more potential improvement and in more ways than just bass control than a 2nd sub at this point in your process.

While I wouldn't disagree with that statement, and understand the benefits of dual subs (I used to have 2 16-46pc+'s arranged in a like manner), I feel that would be an unneeded approach for this situation.
