I bet the 308p can go a few dB higher.
I'd be curious to see similar measurements for the LSR32 as its woofer has an integrated brake system.
But that is utterly off topic, sorry for the digression :D
Back on the topic of compression drivers, did you ever measure a difference between the different 1.5" cores?
When I compared a few of these 12 years ago I remember that the 2452 core sounded way worse to my hears compared to the 2450SL one (less "realistic" dynamic), both equipped with the exact same diaphragm.
I don't know if this was due to the magnetic field ("optimized" at half the weight, both neo), the smaller back cap or the somewhat shorter phasing plug.
That might also just be my personal bias (bigger=better)... or my failure to reliably/consistently install diaphragms :)
