www.soundlabs.com is, but it's a software company.

That's my point. A gunshot, at close range, would probably overmodulate
both a microphone, and the speaker you try to reproduce it on. I'm sure a
speaker can be driven to produce as much, or more db, but not in the same
timeframe, I'm thinking. It wouldn't be a faithful reproduction, although
it may serve the purpose (of spoofing the accoustic targeting system).
