The “Power Alley” – AKA, The Troubling Interaction Of Subwoofers
Opposing subs can create what’s termed a “power alley” – regions where low-frequency energy is too hot. Here’s a quick explanation and a few approaches.

Part 1: Technical risks involving the specification, integration, and application of modern AV technology.
Addressing a host of key questions in the quest to create reasonable and effective SPL policies for venues and events.
Calculating the speed of sound in air and clearing up some popular misconceptions related to pressure, density, and other effects.
A technical analysis of the variety of factors involved in what seems a simple matter on the surface.
We buy a new loudspeaker with a higher power rating and it’s louder. All things being equal, this is true. But it’s important to remember that wattage isn’t the only variable in play.
When two signals are combining at the same level but with different timing in a bus or a loudspeaker, the result will be comb filtering upon the combination. To avoid this, the two signals must be corrected to arrive in time with each other. Here’s a way to do it.
A focus on eliminating severe resonant modes and establishing the low-frequency response of the room, and much more…
The use of dual channel FFTs initially re-shaped loudspeaker product design, but it soon followed that they would also play an instrumental role in developing the art and craft of field-tuning a sound system, an inherently more complex pursuit.
