If you like the Gallo's I think they use Dynaudio drivers.
You could always try a high end Dynaudio speaker if you are seeking improvements. Frankly I can't see how any driver could work very effectively in such a small cylindrical box as used in those Gallos Ref 3.1. ...it seems like it can't possibly be very efficient or free of distortion as pressure will vary significantly during woofer excursion.
