Does A Thicker Baffle Aid In Cone Control?

I would think that to a certain point, a thicker baffle would help keep a more linear progression when subs are getting a lot of power due to the way it loads on the cutouts.

Am I wrong here? And when would it start to lose effectiveness or be detrimental to performance if it's true?

I'm going to have to go ahead and say yes. With a thinner baffle, it has a tendency to flex. Get rid of the flex, the waves and pressure aren't scattered, and you enter the zen state :) It would start to lose effectiveness (and get pricey) after the point the baffle stop flexing.

Plus you want to take the chance that your subs mounting ring is tweaking along with the baffle??? I sure dont... Thicker baffle FTW!

Well, I wasn't so much concerned with flex. That's not a problem. :D

I'm talking about when you dump massive power into a sub (20+k), the cone tends to flex and motor loses linearity. I would think that having it extend back (like 4" thick baffle housing an 18 for example) around the motor, it would create it's own little loading environment assisting in control.

I'm not completely sure about linearity, but the thicker you make the baffle the more it tends to load the subs. If you are doing more than 2 layers of mdf or burch make sure that you take a roundover bit to the inside of the back of the sub cutouts. It will help the air to escape off the back of the cone and flow into the box chamber much quicker.

also gotta watch out for flex though as everyone said

i had a 4.5" thick baffle (6 layers .75") and i was still getting some flex in it

but i think with 15"-21" subs thicker baffles help like that but doesnt help with smaller subs with big motors

on tempro i seen this and figured this is what your talkn bout

It's a tradeoff. If you extend the baffle back too far you run into problems with extreme pressure building up behind the cone, this can cause really shitty oscillation, coil rocking if the pressure is uneven or blown cones/surrounds.
