Woofer advice for sealed box

[shubhendu_pal]

Can anybody advice, which of the following woofers is the best choice for 12x7x5 inch sealed box according to their T/S parameters? It will be 3 way with 3inch full range, so upper cutoff should not be a problem. Dayton needs huge box, SB is for ported and Tymphany has low Xmax and 8ohm only while my mid and tweeter is going to be 4ohm. Which one should i prefer for max bass?

Dayton Audio ND140
SB Accoustics SB13PFCR25
Tymphany Peerless SDS-P830656
