Subwoofer in pushpull ... who is it?

[mprivitera1]

... I'm back, I've finished the subwofer box. I've done it with a 1.0 ft3 capacity so I can use Sealed or Ported Enclosure. At the moment I decided to use it in Sealed, so I put in a lot of sound absorbent to get to ft3 0.39. Here are some stages of construction .....

... I thought to build the three-way cross over with frequency cut 130-2500 Hz .. maybe a little too risky .. !!! now use crossover see below,
Give me advice on how to improve or make new crossovers for it !!!
