I just was confused when sine said cutting the baffle out was time consuming... I was worried there was some kind of angled recess that was on your original sketch. Plan to go old school with a jig saw.

Jig saws are time consuming compared to circular saws or a router .

Using a router with a Jasper jig, a perfect circle can be cut in under 30 seconds.
That said, if you only have one router and it has your round over bit in it, takes longer to change bits and put on the Jasper jig than cut a single speaker hole with a jig saw...

spot on art. It'll probably take you more time to DRAW the circle on the board than it will to cut any of the other panels to size (approximatly the time it takes you to adjust the bevel on your table saw plus one minute)

the braces only take time if they dont fit exactly the first time (which can be quite often).

routers are indeed the fastest, but mine esp takes FOREVER to change the bit, so the 3/8 roundover is pretty much permanently installed.

based on the last hornresp inputs posted in the keystone thread, it looks like tbw100 will take about 1000 watts before reaching the 12 mm xmax. the sim does not take into account the extra "cone control" that is exhibited by the keystone mouth opening (or any of the response changes inherent with the keystone mouth). Neverless, with your amp, the hipass knob should be at 33 (JUST shy of 35), and you should use the 125 hz setting for the lopass. This should allow you to pretty much clip your amp at 8 ohms bridge and still be safe (you will exceed xmax with pure sine waves clipping... but the TBW is a sturdy driver, so I wouldnt be too worried). If you have a PEQ, take a 3 db notch out at 133, and another one out at 195 if possible to smooth some peaks.

get the driver dude! We have faith in you!

We think alike! The plunge router is table mounted...

Thanks for the encouragement. As fate would have it, Parts Express has extended the Labor Day sale. Resisting all temptation to order 2 drivers to get the $50 discount.
