nice - i just checked in and realised there was some feedback. TC I'm glad this has helped you - make sure you post some pics and feedback when you're done!
please feel free to pm me with any questions - I'm just in the process of having the 'with base' version made for mine - i'll post pics and some follow ups soon enough...
btw - i'm adding a detailed drawing of my final box with cutout dims for the 8" sub (the hole at the top is for a 2" speaker wire terminal)...
