Two 8 inch usher vs one 12 inch M&K

[qguy]

I currently have an usher 2 way with the 8945 woofer, an active 12 inch M&K sub is also used, I am thinking of getting rid of the M&K and construct a sub using the two Usher 8955 woofers, would these be a good idea ?

I thought of the Usher 8955 woofer as it might be a better match for the 8945 woofers
