I COULD give you a whole lot of help, since I have the same subs in a 7 cu ft ported box, but why would I when you were such an ass clown? Maybe an apology would be nice.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I have an Audiobahn A18001D amp running to them at one ohm, each sub is seeing ~950 watts, if not more. Here are the specs on my box...

Construction Material = 3/4" MDF

Box Height = 20"

Box Width = 36"

Box Depth = 20"

Number of Ports = 1 (Slot)

Diameter of Ports = 18.5" x 4"

Length of Ports = 23"

Port Area = 74 square inches

Box Volume = 6.83 ft^3

Box Tuning = 35.85 Hz

WinISD Estimated Peak SPL = 37.5 Hz

WinISD Estimated Peak Port Velocity = 28.62 m/s @ 35.4 Hz

I don't know the history, but it's amazing what a simple apology will get you.

We simply got off on the wrong foot. No biggie. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Hmm.... is that velocity at the 950 watts enterend into the 'signal' thingy?

I'm trying to see what I get for my subs and have 2.something at 1 watt in there.. then up to ~35 m/s at 500 watts.. is that right? and if so, what is the upper limit I want on velocity so it's not audible?
