Changed Speaker Placement NOW BOOMY

Hello,

I have a bit of a problem. We bought new furniture for the living room where the stereo is and after replacing a couch, adding a chair and moving the speakers and audio rack down about 2 feet towards the corner and the speakers which where about 3 feet off the wall before are now about 14" off the wall.

I now have this unnatural sub boom and since I am using thiel 1.6 which have very little if any sub freq I can only assume its the room.

I understand that moving stuff around can do this, but its such a big change and I really dont have much room to play with.

Are there any cheap cheap cheap ways of fixing boom bass in a room.

The room is 12' X 26' with 9' ceilings.

If you look at my system pix the stereo is sorta in the same place with minor adjustments.

Any help would be super awesome.

Your best bet would be to get a material sample from the Misses to make sure you are in compliance!

I mean no harm or disrespect but this is a really fun thread on a subject that we have all dealt with at some point in time. :)

Counting on your success and a first edition of your fourthcoming how-to-book.

If I realize that panels are needed after a few days of listening then I will outsource a project to Timlub. If he could build panels that look streamline and also maybe act like a light source then maybe we are in business.

I saw in Home Depot last night these awesome looking LED high hat bulbs, I was thinking today after Timlub mentioned panel how could I make these thing disappear in the room then i thought maybe I can have one of those facing up out of the panel or column for that matter, behind the speakers. That would look sweet.

I've never put lights in them, but shop for low voltage LED's. It wouldn't be tough and I could certainly guide you through it.
If you end up needing them, approach your wife looking for her advice, ask her for help, get her involved, let her pick out fabric.... or put a space heater out on the porch, its getting cold.

LOL,I am going to spend the weekend listening to all types of music and see where I am on Sunday. I printed out the instructions on the Sumiko Method and I will see what happens there.

Oh and I order a Project Tube Box II so that's the other reason why I cant exactly mention acoustic treatment, maybe by the holidays I can.

If I get kicked out does anyone have any vacancy's?

Thegoldenear,
If the Sumiko method gets overly difficult and you are in a standard rectangular room, the Cardas golden triangle also on the same site, should be very similar in final placement. It has already figured basic room geometry and gives measurements that will put your speakers at their optimal placement. I have seen in narrow rooms, where the Sumiko method would give better results, because of boundry issues, but normally, you should end up with very good results either way. I only mention it for ease of use, not because its better. Tim

I would also endorse use of the Sumiko method. When using this method, it is surprising how much bass response changes with the smallest of placement change. That means that one could find a spot that at least minimizes boom while staying reasonably close to the current placement.

If placement change does not help, use of some form of equalization is the most realistic approach to removing a boom. At low frequencies, room treatments (bass traps) must be pretty big in order to be effective -- unless one is allowed to take up a lot of space in the corner, this is not that practical in situations where room decor and space utilization are a big issue.
