What was wrong with the cut? I used a cheap-o 1/4" cutter and had great success with it. I bought a nice spiral up-cut bit too, but didn't like the $25 price, so it is still sealed up (thus the reason I tried my cheap bit and it worked will). For someone forward facing like regular speakers, I would probably do the spiral upcut bit as recommended by a lot of others for making circles with something like the Jasper.
