Re: THX Style Baffle Walls for AT Screens

Good one.. Take lots of pics..

I made a further improvement to the Baffle Wall last night..

My construction leaves an opening at the top and bottom..no perimeter frame..
Whilst the bottom opening goes down to the floor carpet, the top opening goes up to the plasterboard ceiling..
I felt that this might tend to reflect some of the higher frequencies and interact with the front wave to some degree..so I fitted some convoluted foam on top of the wall, covering the open area..

I noticed an improvement straight away with a much smoother mid to high frequency response..
Voice clarity improved as well..
I watched Iron Man 2 and in this movie, Tony Stark (as his character depicts) regularly tries to talk over everyone else and rapidly and you're trying to hear two conversations going on at the same time..
I noticed that I was able, for the most part, to clearly hear each word in both conversations..
There is also some drum beats in the movie and they came through very strongly and clearly..

The Baffle Wall just gets better and better!!

I noticed that on your pics and wondered if that would cause you any issue. Clearly it did and you resolved it quickly. Well done.

Re: THX Style Baffle Walls for AT Screens

Thanks Mark..The fronts are now sounding like I've expected them to sound..
The sub on the other hand is still not completely to my satisfaction..I'm very limited for placement as the sub sits on a sand filled base..
I may have to get an Antimode 8033 EQ unit to balance out the lower frequencies..

Re: THX Style Baffle Walls for AT Screens

I have a question I hope someone can answer. I was planning on using 2" OC703 covered in black cloth on the wall behind my AT screen but stumbled onto this Baffle wall discussion. Would that be close to the same as a baffle wall?

Old question, but in case someone is reading excellent thread....the answer is: Not really unless the speaker faces are flush with the front of the OC703.....and more important there's a solid wall behind the OC in which the speakers are mounted. It's really about the solid wall, and less about the damping on it.

Re: THX Style Baffle Walls for AT Screens

How do I know if a baffle wall is the way for me to go? I have JBL 2360 horns and custom bass bins, La Scala bass bin center with EV horn and a DTS-10 sub that are going behind a 18' wide AT screen wall. None of the speakers are ported and all but the sub and the custom bass bins will be right up against the screen or a least within 6" of it. The sub will be firing 2-3' behind the wall and the custom bass bins are shaped like a pie with the curved area facing the center and screen area.

One of the biggest reasons for them: Increasing speaker output (more SPL). Do you need more SPL? (Doesn't seem like you would, based on what you describe! )

112db with 1 watt at 1 meter... I don't think I need more SPL. I think I could hit reference levels with a headphone amp on the horns.

Okay so the other reason often cited for a baffle wall is to reduce diffraction, for clearer sound. But especially if one tries to get fancy and not have a flat wall, it is apparently easy to do more harm than good.

Do you mean it is easy to do more harm than good with a baffle wall?
