Welcome to AC 
If you have a hi sensitivity speaker as 100dB there is no much things to upgrade IMO. Today audiophiles can take advantage from inexpensive and transparent powerful Class D or GaN-FET amps and recently with Lii Audio, also take vantage from inexpensive big cones full range drivers, this will save a lot of money hence no crossover and no enclosure need.

This is a inexpensive DIY project from a AC member, it have only four(4) parts: Eminence Alpha15A + 4.7mH + Visaton B200 and a MDF baffle.


Other option are the Lii Audio F15 FR driver $399/pair, not each.
Here Decware OB with the Lii Audio F15 driver:

If one have a woodworker is possible try the Lii Audio F15($399/Pair, pair not each) 97dB/8Ω and benign impedance curve suited to OB or Bass Reflex box or the F18($540/pair), no Crossover, no Tweeter beaming, no Phase rotation, no driver sensitivity loss, no Harmonics loss, no Retail price.

My personal choice is the Lii F18 in Single Driver configuration, but if you make question of wanting a 2-Way speaker you may want a bigger woofer than the Alpha15A, so there are W18 inches and W21 inches from Lii Audio, personally I dont like these two VCs woofers, they are hard to drive with a small tube amp.
