rgds, sreten.
The SPL chart in the second image in my previous post is charted at 250W input, which would be about where both drivers run out of xmax in that particular box size/tuning (see first image).

Here's WinISDs estimation for both Xmax and Pe limited SPL...

diystuff,

I've used the Daton 15" and its an awesome driver. This sub is part of a surround system I'm building. It will definitely shake you.

Alright guys...I'm staying with the 12 inch Dayton reference. It seems to be better built than the 18 inch dayton and it has better reviews. Now, if I order this driver from amazon, do you think it will arrive here in Europe without any physical damage? I have some relatives in the states and I could possible send them this driver and they could pack it better and then send it to europe. Also, one more question, I will have a 150 liter box for this sub...will it lack in the 'punch'? The f3 will be like 17hz.

Tuning so low doesn't make sense. Would anybody agree?

I have the dayton 12"HF sitting right in front of me in a 170L box tuned to 15hz and it in no way lacks 'punch'.

I posted my in-room measurements here: my "little" build

The port is 20in^2 (~129 cm^2) via. 2.5"X8" opening, 34" Long and has no chuffing issues. Two 4" round ports would give you ~25in^2 so you should be good.

Tuning "ultra low" (below most program material) actually has a lot of benefits.

Thanks man! And you have a CRAZY build there. The numbers are just wow!

Hopefully by this weekend I will get some calculations and a design on google sketch done.
