Lots going on from woofers to EQ circuits to cabinets...nothing specific on a model by model basis just yet. Stay tuned!

JohnK is correct. The only change that we have to make from a measurement standpoint is to measure with a microphone at a point equidistant from both woofers. For a subwoofer in a 4-pi environment, like on our outdoor measurement tower, we don't need to be too concerned as the frequencies we are dealing with are omnidirectional anyway.

We've started putting a few lab pics up on Facebook showing the subwoofer development (https://www.facebook.com/AxiomAudio). Today was the breadboard shot:

Where is the blue LED? You can't do a test breadboard without a blue LED and expect us to take is seriously!!

Oh it's there, just out of view in this shot! Blue LEDs are a must on any project board...they seem to have a calming influence when working with tight deadlines. wink
