Drilling holes for tweeters

[dakotus 10+ year member]

Looking to install a set of CDT comps tonight. The instructions say, to drill a 1-11/16" hole. Heres where the fun comes in. I'm willing to bet that I will never need to drill this size hole ever again, so read..cheap is better. Just need to drill 2 holes, and I dont care what happens to the bit afterwards.

I'm having a hard time finding a 1-11/16" holesaw at Sears,Home Depot, and Lowes. What else would be a good way to get these holes drilled? Would a spade drill bit work assuming i could find one in that size?

Maybe you could find a Unibit that had that size...

I hesistant to recommend a spade bit because that's going to leave a nasty hole vs. a hole saw or stepped Unibit, which should leave a very clean one.

get a hole saw slightly larger, or slightly small then widen it a little with a dremel...

They make unibits that big? Maybe I should **** it up and order the hole saw online
