How to Build a "Dead" Front Wall?

Hi all,

I'm reading up on LEDE control room design and am confused by these stated requirements:
  1. The front wall should be "dead"
  2. The speakers should be flush-mounted

That's fine, but flush-mounting speaks of concrete and other heavy (read, "reflective") framing. And, clearly, they don't mean to suggest hanging absorptive panels on a wall with flush-mounted speakers - 'twould introduce reflection points and defeat the purpose.

So, how does one go about building a "dead" front wall? Pink insulation between the studs? Extra-thin drywall? Can I put wood paneling on my dead wall?

Any enlightenment is greatly appreciated.

For a flush mount front wall in an LEDE room, the use of "dead" means non-resonant rather than absorbent. It can get confusing if you read old articles on LEDE because there were some rooms built where the front wall was highly absorbent and the back wall was reflective/diffusive but most professional designs are the opposite. Read up on RFZ if you have not already.

It's going to need to have lots of mass and be pretty rigid. You could build a wood structure and sheathe it with 2 or 3 layers of drywall and insulate it with rock wool, for example. Or take a composite approach with studwall / drywall covered by wood paneling or a wood/concrete hybrid.
