Martin (Azura horn ) is making for me extension to 2.75" (BC 8p21)and 1.4" for 204 Hz (altec 288c) .He also developed 550 hz horn for S2 . He understands importance of smooth driver -throat transition . It would be ready to go solution for you with matching aesthetics and sound of your lower midrange and mid channels.I think you could use Jesse's technique of adding plaster to the back surface of horns for reinforcing their walls. Unlike for us in US (dolar depreciation ) those horns are still relatively unexpensive for EU customers .My listening space is simmilar to yours and I can't imagine 160hz horns with Le'Cleach flare for lower midrange and additional 50-60 Hz midbass not to mention that you'll have to fit somehow a bass channels too.
The drag is that it may take a few months to get those horns from Australia. There is also BD -Design variety of tantrix Oris horns (second hand??) made for 8" for which you could just make an extension to fit your driver. Check out E-pay for German or Balkanian horn manufacturer . Those are really well made tick ,heavy plastic horns which may fit a budget and they are local .
