First IB Build was done in a few days in March 06
Still awesome SQ that I love, as do everyone who visits including 2ch audiophilic types
Manifold is of 2 x 19mm ply thickness and weighs over 40kg without the drivers. With drivers about 80kg and was a heavy lift with strop over my back to lower into place whilst someone else bolted in
The last shot is a size comparo between an old B&W ASW1000 box sub and just the 18" avalanche driver
Front IB is 2x 18" Avalanche driven by SGR501 subamp, wired parallel at 2ohms. Sub amp is rated 500watts @8ohms class AB. During stress testing we measured 400watts on the amp manufacturers oscilloscope - the house was groaning and I was fearful to go further. A visit next day from the EPA suggests it was loud at the neighbours also (oops)
