If you have the H290C waveguide, it sounds like you're upgraded as far as you can go, at least as far as "factory upgrades" are concerned. You could replace the B&C driver with a TAD TD-2002, but I've never offered it because of the price. It isn't just "audio jewelry" though - its beryllium diaphragm provides extended HF without breakup modes in the top octave.

One other thing I might mention is multisubs. The four Pi design really benefits from at least a pair of flanking subs. Better still is to have a pair of flanking subs and a pair of distributed subs, placed further away and setup as multisubs.

So that gives you upgrade possibilities for both ends of the audio spectrum.
