That's why subs and cars go well together. They are both all about moving AIR!

I need this for my butt. Strange resonance and droning when I get up to go pee at 4 am???😝Folks are using these filters in exhaust systems to prevent droning at highway speeds.

Got a sim for this beauty ?Looks like a single fold tapped tapered quarter wave tube or pipe (T-TQWP or T-TQWT) to me.
Basically, a negative flare tapped horn or a negative flare port BP6S.
Double fold version.
9" high x 16" wide throat.
5" high x 16" wide mouth.
10 foot horn.

D@mn, I'm on my phone and all the pics in my thread are gone. I do remember some of the numbers.
S1 = 929.03 cm2.
S4 = 516.13 cm2.
L12 = 20.32 cm.
L23 = 264.16 cm.
L34 = 20.32 cm.
Vtc = Sd × 1.905 cm.
Atc = Sd.

So our son came home for Christmas yesterday. We were bumping from about 3:30pm to 10pm. We actually got the SA1000 to cut off on Eric Sermon & Too Short, "Buy You Some." Here is the damage to the upstairs' master bedroom. Remember, this damage is from the least efficient TH you can build.
I think you have to actually move the exit location and change the exit shape like weltersys' Keystone TH.

- Loudspeakers
- Subwoofers
