Sorry, that is not true for movie mixing stages. The surrounds are usually the same ones (or very close) to those seen in a local cinema, and they do not have much bass response below 50Hz or so. The L,C,R stage speakers almost always have two 15" woofers in an 8 cubic foot cabinet, tuned for 30Hz. The spectrum above 500Hz or so is covered by a constant directivity horn and compression driver, occasionally with a smaller horn and driver covering the highest frequencies. The subs usually contain a single 18" driver in an 8 cubic foot cabinet, and depending on size, the room may have from one to four of them. JBL is the dominant supplier in this market. Mixing stages for film do not use bass management as a home theater would.

The situation for strictly music mixing studios can be significantly different, as there are no real standards for the speaker array used in these rooms. Movie mixing stages must conform to standards so that the mixes performed in them will translate to all of the local cinemas with mimimal change in the sound of the mix.
