The Pro5100 driver has a lot of positive attributes, one being a good combination of sensitivity and efficiency mixed with a large amount of displacement. While it may not seem obvious to use a driver like this in a sealed enclosure due to the roll off starting up very high in frequency, this is due to extra sensitivity up top, not loss of sensitivity down low. As expected the 5100 provides a ton of upper bass capability and a smoothly extended response. It does not have the ability to move as much air as some of the top displacement drivers but it is no slouch and still has enough to get the job done. Despite being much better suited to bass reflex or horn alignments the 5100 can still provide a good showing in a sealed enclosure with the help of some boundary gain in room or vehicle and a little equalization. Subjectively it certainly sounded exceptionally good with music during listening sessions while still maintaining the guts for loud low bass when needed.
