Hey, is it safe to assume that a router bit will not alter the size of the original hole that you cut out for the driver (like a non-cutting part at the bottom)?

By the way, I read a tip on the burn-in. I read it's a better idea to do it in intervals (i.e., shut them off at night) because 100 hours straight apparently won't have the same effect.

this is the type of bit I use

for nominal 1/2" (12mm) material, the gap between bearing and beginning of cutting edge means you can't remove all that much material - for maximum removal, and since my baffles are generally rebated for flush mounting, I usually tape both fronts face to face and clamp to bench to although the bearing to run on the underlying piece

The pin-cushion pattern of Fostex frames should put the mounting screws outside of the extent of the chamfer.

the spectral content and power levels at which they're run is also rather significant

You still have to set the depth properly. If you mis-set the depth, the bearing won't help. The part the bearing is riding on won't change size, but everything above it is fair game.

The best answer to questions like these is to get some scrap and try it out for yourself. More lasting impression that way.

preach to the choir brother fastbike - no substitute for experience - after over 10 yrs of fiddling with these Fonken designs (sorry, I just can't resist) and others, I'm still fine tuning my techniques, and wasting the occasional piece of plywood

No significant progress (not much time). But did start burning the fostex drivers a bit. I'm actually surprised at how good they sound just like this. Makes me excited for when they are in an actual enclosure.

Did you find it tricky to connect to the Topping amp? Is a bare wire easy to connect?

I'm glad to hear they sound good in cardboard boxes. I know I'll be too lazy to build enclosures for my drivers for a while. Teehee.

Bare wire was very easy on the model I have - there is a removable screw down 4 wire plug on the back. Easy to use. Loose screw, insert wire, tighten screw - done. Looks like it will support 14/16 ga if needed.

Removable screw? Do you mean the part that looks like a binding post with plastic on it? Is that what you can unscrew to connect a bare wire?

We may have different connectors. Mine has something a bit like this on the back, but that fits into its own jack and is removable. Each screw tightens down to clamp on a wire.
