I don't know, but being down -22dB @ 20Hz doesn't sound like a good start for a subwoofer system.

looks like a small box and a high rolloff. What does the excursion graph look like at 250W? I would try for a larger box and lower tuning. Something like 60L and 25-30Hz?

The excursion graph showes nothing because i dont have the Sd parameter of the sub.Is there a way to find it ???I couldent make the grap linear for a biger box and lower tunig. Maybe i am
mistaking somewhere

Thanks

You should geta good idea for the area of the cone (Sd) by measuring the diameter of the cone and using the area of a circle formula. I think it is area = pi*radius^2.

I had a look at several 12" drivers and they look to be about 500 cm^2 for Sd.

Thanks so mutch for your interest and help but i think it's not worth of risking with this kind of sub that doesent have all the T/S parameters and i will try constructing a box with the infinity kappa 1203 se. It is about 50 euro more expencive but i think it is beter than this magnat.Is it??

Although the magnat(or a sub like magnat) doesnt have all the T/S neaded it is a real chalenge for me to make it sound good but i don't have the big expirience to do it and thats the reasone i posted this graph.
