In a riser constructed with 2x8s, for example, make the holes between each pair of joists (preferable - between every other pair at a minimum) as wide and as tall as possible.

As a home theater enthusiast, there can be nothing more exciting than planning out your theater room. You know exactly what gear you want to use, where it will be located, the wiring, etc.
But what about the most important part of the theater? The one that is almost always forgotten, or put on the sidelines during your planning - the chairs. Most medium-sized theater rooms require at least two rows of seating. Unless your room is already constructed in such a fashion, you will need to build a riser platform. But why limit the functionality of your riser to simple chair elevation? I say kill two birds with one stone and make it an integral part of the theater experience.
I wanted my riser to not only elevate my seats, but to help smooth out bass response and increase tactile response for all of the seats residing on it. With that in mind, I called our friends at Auralex - our official acoustics sponsor of the primary theater room in the Audioholics Showcase home. Auralex prepared a basic design sketch for me to follow and it was up to me now to determine how big I needed to make this riser.
The above diagram shows the basic structural layout and design. Notice the front ports which I actually doubled up on more on this later and the Auralex U-boats which are used to mechanically isolate the riser from the rest of the flooring. Placement is strictly a function of where the best location of your seating area is in relation to the soundfield. In discussing the riser design with Auralex, I took some notes as to how to best maximize its design effectiveness:.
Make the volume as large as possible. If there is a choice between 2x6 or 2x8 joists, go with the 2x8s. Make the front openings as large as possible, while still retaining the structural integrity of the riser.
In a riser constructed with 2x8s, for example, make the holes between each pair of joists preferable - between every other pair at a minimum as wide and as tall as possible. Shape is not really a big deal so much as size. The U-Boats shown in the illustration are critical. These will not only "float" the riser, but even the addition of the small airspace under the joists which will decouple the riser from the main floor and improve bass definition.
Select dense top materials for added rigidity and minimization of mechanical noise during resonance. MDF is much better than plywood in this regard. The more you fill, the less tactile response you will feel, the less you fill, the more resonance will be perceived.
Acoustically, more volume is better. But we all know how ergonomics win out sometimes. Each of the 2 x 8s form quasi internal bulkheads, partitioning the internal volume of the riser into individual, semi sealed chambers. It was necessary to decouple the riser from the floor using the U-boats to increase tactile response. I felt the trade off of better tactile response vs.
Think of a cola bottle. Blow over the opening and you hear a tone. A whole collection of similar bottles will absorb a significant amount of sound at a narrow band around that frequency.
