Mesa Ph155: 3015lf vs replacement Mesa 15

[bassman10096]

I've been playing a Mesa PH115/410 stack and enjoying it. Recently I acquired a PH212 to replace the PH 410. I love the PH212 paired with a larger Bag End S15B-D that's loaded with an Eminence 3015lf. I'm interested in opinions on loading the Mesa PH 115 with an Eminence 3015LF. Assume would always pair it with the Mesa PH212. Here's the data comparison:

• The 3015lf sounds great in my 6.3 cu ft Bag End cab - How would the 3015lf sound in the 4.3 cu ft Mesa PH 115 cab? The 3015lf speaker specs recommend a cab with between 3.6 - 6.8 cu ft. in volume.
• The Mesa replacement speaker is rated at 400w/8ohms. The Eminence 3015lf is rated as 450w/8ohms. Any power issues or issues concerning the tweeter/crossover??

I have the cabs and drivers to try out the swap, but I'd appreciate feedback from the experts out there before I start moving drivers, etc. Thanks

Bag End may have a custom version of the 3015LF? All you ever read about the 3015LF is how it's a great subwoofer but not useful as a full range for lack of mids, then again that might work in its favour mixing cabs.
