Dimpled ports

Bowers and Wilkins uses ports with dimples. I don't think you'll gain 4dB by flared or dimpled ports. Tune way higher and open it up to 140-160" of port and you may get that.
I am tuned at 38 right now and get a bump at 48 from the truck. You going to be in Sanford on the 29th of Sept? and did Mike make it down to check out his explorer you are working on?

I didn't get a great look at your box. I'm sure you have room to gain, but don't expect 45's

I will probably make that show actually. Mike was down here yesterday. We got a good bit of work done on the wall. I think he's coming back down Saturday.
