Not any louder in what way? I mean for a given driver there's not going to be much difference in peak efficiency, just as it gets bigger, tuned lower it will maintain it to a lower frequency when properly tuned. AFAIK the H110 was limited to single drivers, so may need a lower cab tuning.
Me, no, other than being a 'talking head' I haven't been active in any DIY audio for nearly two decades and > three decades in prosound apps, though you might bhave some luck posting them on FB: https://www.facebook.com/groups/1598234160391737/
