I have had Belles, Heresy II, Heresy III, Cornwall II, Cornwall III, Forte I, Forte II and Forte III. The only one I did not like was the Belles. They had a cabinet resonance or a hump around 200hz (estimated) that I just could not live with. The Heresy II bass response was not only limited in extension,(as all Heresy, Belle and La Scala are) but basically shelved down about 3dB the whole range of the woofer. Heresy III corrected that. I actually prefer the Forte I or Forte II over the Forte III. The Forte III is not as smooth in the midrange as the Forte II to my ears.
You can get by without a subwoofer with Forte or Cornwall (and of course K-horn) but you will be missing at least another full octave with Belle, La Scala or Heresy.
