Danny,

I thought you may like to know I have completed a Open Baffle True Dipole project based on GR drivers except the twin woofers. The speaker configuration is TMMWW, refer to images attached.

T - T3
M - midrange M130
M - Mid woofer M165X

W- Eminence  Driver similar to those use in V2.

For further details refer to True Dipole Project under the "Open Baffle Forum".

Nicely done,

Are you thinking about active EQ or gain for the woofers? looks like they need some boost unless you have enough in room gain. I really like the sound of OB bass. Why you decided to build a box for the 12's

The "box" for the woofer is actually a U-frame, i.e. open back. 2*12" woofer gives very high efficiency, and I have reduce the overall gain via the Behringer or the reduce the volume gain from the woofer amplifier.
