So I have been working for almost a year on a recreation of the Disney Tower of Terror Basement which serves as the room prior to the entrance (though simulated elevator doors) to my home theater named the Tower of Terror Theater.
The room has been physically been created to reproduce the Tower of Terror basement, and along with the physical set, an automated sequence of audio, visual, and special effects props have been incorporated and designed to start upon the push of an elevator button.
So one of the effects is a video seen through one side of the elevator doors (through perforated vinyl) showing the elevator failure, fall through the shaft, and crash to the floor. I just recently edited an elevator plunge and crash clip into the video shown through the elevator door, taken from an old Tower of Terror Commercial. Here is the link to that commercial;
So currently the sound equipment used to broadcast the audio in the room includes:
Sony STR-ZA3000ES AVR to power the ceiling speakers
2 ceiling mounted Earthquake Sound 6.5X 2-way speakers
Acoustic Audio PSW-12 500watt 12-inch Down Firing Powered Subwoofer
I am hoping to get the feel/vibration for viewers standing 4 feet away from the elevator door of an elevator plunging down the shaft and crashing into the ground. (We will be putting in tubing so that dust will blow out the bottom of the elevator door as seen in the commercial when it crashes to the floor). The floor is concrete slab, so I assume the best place to put any device would be on the weight bearing wall to the right of the elevator doors. I dont know if this would work or not. I have come across the Buttshaker LFE, but wonder if anyone has any other suggestions for other equipment that would give as realistic feel as possible for this effect. My budget is <$1500.
Here is a link to the most recent video of my project.
