Sealed 1x12 Simplexx Bass Flab
Sealed 1x12 Simplexx Bass Flab
I just finished a 1x12 sealed Simplexx (no tweeter) with BP122. It farts on my 4-string from the low G down to E, even with the EQs at 12'oclock, and a Broughton HPF set to 35hz. All bracing is rock solid. I am 100% certain it is air-tight, and done to spec. I have a conservative use of Polyfill on the sides and back. Any tips on eliminating the flab? Or is this the nature of sealed boxes, having less capacity?

Re: Sealed 1x12 Simplexx Bass Flab
Don't know what kind of amp you are using, but it's a $100 speaker that rolls off hard at 100hz with only a 6.2mm xmax. You can't expect to hit that really hard and expect it to not fart out. You might try turning back the low end a bit and raising the HPF to about 50hz. That will help with the excursion. And you really won't miss a lot.....most bass cabs don't get below 50hz anyway.Jakevw wrote: ↑Mon Dec 20, 2021 6:26 pm I just finished a 1x12 sealed Simplexx (no tweeter) with BP122.
