    As a continuation, here are the parameters for the 12″ drivers as people have requested them as well. These are the original parameters as provided by Lambda Acoustics. Again these are for the 8ohm versions. Most have other impedances available as well. Call or email for more info.

    TD12 dimensional drawing is here. This applies to all of the TD12 woofers.
