Axiom Home Page Forums General Discussion Home Theater how do professionals do sub-placement?

That would definitely help (as would a BFD) but you pretty much have to leave the SMS-1 or BFD at the customer site, ie customer buys it, pro hooks it up and pushed a couple of buttons, customer thinks "geez, I could do that"

Oddly enough, not a single installer we talked to even hinted at using any kind of measuring equipment, either for simple frequency response plots or most sophisticated decay & echo analysis.

With the real acoustical engineering firms it's a different story, of course.
