Hole pattern for a 15"

...i just hav this image in my head of him standing there, wild eyed and raving, pulling at his hair and screaming at the night sky!

All very true.... (other than the hair bit...bald as a coot...)
All I kept telling myself was, well I have come this far...just one more thing to try to see if it works.....

Stu, My eminence 12" Neo drivers had a slightly different bolt centre spacing than the B&C Neo driver that I tried out in my first DR290...

I only found this out when I tried fitting the correct Eminence driver into my DR290 and found it wont fit......

I had to buy a flexible shaft drill to re-drill the mounting holes...any body who has built a DR will understand how re-drilling the mounting holes inside that tiny chamber was no small achievement....

I will never build a cab without the drivers again......

Did you just drill out the existing holes a bit? I don't see how you could put in T-nuts after the cab is built. One of the T-nuts came out on one of my DR250's, I just sealed over the hole and let it go.

The speaker baffles on my DR280-290 are circular and pretty much the exact size of my drivers, and as such I had access to the rear part of it unlike a sealed DR250 baffle which extends top to btm and side to side.

What I did was remove the original T nuts (simply by tapping them out with a bolt in place) and re-drilled a new set of mounting holes using a plywood template clamped over the DR speaker baffle.

Once the new holes had been drilled using a short chuck flexi shaft bit, I placed the T nuts by hand and pulled them in using a bolt and flat washer.

It was a very tight experience, and a lot of swearing was to be heard from the garage.......

You learn by your mistakes.....
