Used to flush mount the sub?

I have these two so far, would anyone suggest any others? Need some good bits for the router I bought today and heard Freud was the best.

Freud 75-102 Double Flute Up Spiral Router Bit (http://store.yahoo.com/freud-tools/freud7514ups.html)
Freud 34-116 1/4" Rounding Over Router Bit (http://store.yahoo.com/freud-tools/freud3414rou7.html)

I don't think it's a bit, normally it's just double baffle with the outer baffle having a larger circle cut in it...

Nah I'm pretty sure there is a specific bit for it. The way you are talking about is the way i've always done it but I'm pretty sure there is a bit to do it also. It doesn't make it as deep with the bit, only about a half inch instead of the full 3/4

just don't plunge all the way through the wood

uh, set your router up right? why would you want to cut 1/2 an inch out of the mdf then mount your sub? It would almost fall right through

To flush the subs you use the same bit you use to cut the sub out. 1/4 spiral upcut. just make the last baffle the OD of the sub.

Not if the baffle is 1.5 inches. I'm not a retard.

No box builders i know cut 1/2 out the wood to flush the subs. All use another piece of wood. But people do it to make like baffles for tweeters etc. Just use the 1/4 spiral upcut set your router so it only plunges so deep and keep making 1/4 passes however big u want the circle

Pretty sure. Just want to make sure I get all the necessary bits at one time.

wtf, isn't that just a double baffle? Exactly what I said? Why would you double baffle then use a router to flush mount? Just cut the outer circle bigger...

What you're thinking of is called a rabbeting bit, but I'd want more of a lip to support something as heavy as a sub.

For flush-mounting a tweeter, that'd be different.

I think what you are looking for is called a rabbit bit............cut out the circle starting from your inner circle diameter and work out to your outer circle in increments...then cutout your mounting hole last
just plunge it down to the depth you want it mounted/flushed at.....if it's a 1/4" bit it will carve out in 1/2" at a time...so do the math for each pass and mark accordingly on your jasper jig...make sense??..lol
so if your first cutout is 11 1/8 then the next is 11 5/8 then 12 1/8 and so on till your last pass...

d@mn you JimJ you beat me to it...lol
but like JimJ said this is more practical to do when making rings for flush mounting mids/tweets :fyi:
