Like the title says, I need help with designing enclosure for P Audio E12-300S.
I plan to use one or two of them with a twitter in a 2 way system.
My only problem is, is it possible to make that speaker go down to below 100 Hz without self destructing itself since it has 300W AES, only 3.4 mm X-max, and manufacturer says that it can be used as a subwoofer or in 2 way. How do you put 300W in it without moving cone too much? This is my first time with this kind of speakers, so I don't know what to do.
Here are the parameters:

If you use a sealed cabinet you will be able to get 300w out of your sub.
The internal air pressure will suspend the cone.

Download WinISD Pro/Alpha and play around.
How much power do you have?
Do you have any processing available? - active crossovers etc
A ported box with a properly-selected highpass filter (to cut out the low bass which would damage the speaker) would make best use of the available cone excursion while providing some ventilation for the driver.

I want to use it in two way with tweeter, not as sub, but I would like if it could go below 100 Hz and be as linear as possible, but just can't find a way to do that. I have one 600W and one 1500W amp per channel. I plan to use 600W one for them. I have WinISD, that's where I tried to calculate it at first. Currently I don't have any active crossovers that are functional.
Is even possible to have linear output with it going below 100 Hz while on 300W? Main problem is cone movement that is too much for the speaker.

I was worried that this is the solution. But with high pass filter at 100 Hz or maybe even higher, 300W per speaker will be fine?
Most manufacturers add 1/4 gap depth to the Xmax, by that standard the e12 has almost 6 mm Xmax, which is plenty if you give it around 300 W.
I would use it in a 50 - 75 liter cabinet, closed if you don't use a high pass, tuned to Fs - 80 Hz if you do use a high pass. Closed it will produce usable output from 50 - 65 Hz and up.
Best regards

P.Audio are very conservative with the xmax compared with other manufacturers, many add on 1/3 gap depth whereas P.Audio give the true mathematical xmax. The magnetic field extends beyond the gap so 'linear' (ok, let's say useful) behaviour continues beyond the true xmax. The driver can move significantly further still before damaging itself. I can't see why that driver shouldn't be fine well below 100Hz in a vented or sealed enclosure for PA use.
In my experience that driver and P.Audio drivers in general are pretty durable.
