Default Scallop baffle?

Is there a point to scalloping the subwoofer baffle? By scallop I mean put a chamfer on the inside of the driver cutout on the baffle to allow it to breathe. I know this has a decent effect at mid and high frequencies, but does it affect subs? My baffle is 1" thick.

Generally it is a good idea, but it depends on the design of the basket and the thickness of the baffle.
You're talking about chamfering the driver cutout facing the inside of the enclosure, and drivers that are being front or flush mounted, right?

Indeed I am. I'm trying to decide whether or not it's worth getting out the rasp and filing away some mdf in the morning.

Easier to use a router with a rounding or chamfer bit on it. Takes about 30 seconds.

Cabinets are already glued together, unfortunately. And I don't have an upside down chamfer bit (nor do I really want to get out the router again). I'm fine with filing away at it for a bit if it will make a difference.

Generally I don't bother with speakers larger than 6.5" or so. What drivers are you using?

It should make a bit of difference, though I'm not sure what exactly it would do. The speaker may behave as if it is in a smaller cabinet if there is more resistance to airflow. But that is just conjecture...

You are using Dayton Reference subs? (did some digging ) I wouldn't bother in that case, but if you had a sub like pictured below, I would.

Another option would be to simply rear mount them. That would give the maximum airflow, but then you have to deal with the front edge, kind of ugly as is, but I doubt it would negatively effect a subwoofer system.
