The original design used the same drivers as the current 5.1F sans the 50mm dome midrange. Furthermore, I dont think were any x-over differences between the US and Asian models, however there was an obvious x-over redesign with the added dome midrange unit.
Nicely done, sac8d4. The lineage of this model is this: Originally the Diva 5.1 was more or less a 2.1 with an added woofer and floorstanding cabinet. It was a 2.5-way, with staggered crossovers for the two otherwise identical 6.5" alloy midbass drivers: One extended to the tweeter's crossover point, the other did not.
TAI then introduced a taller, newer 5.1 with a dedicated dome midrange and configured as a true 3-way (the bass drivers now ran in parallel throughout their band) and for a time we called it a 5.2 so as to differentiate it from the original, discontinued 5.1. This 3-way model is now discontinued as well. Of the original Diva X.1 line, the 6.1, C3, and R3 live on, and the 2.1, 4.1, 5.1, R2, and C2 are discontinued, as is the Sub10.
With the advent of the current Diva X.2 range, we reverted the model to the original 5.1 naming, and allowed the 5.2 moniker to be reused for the completely new 5.2, which joins the 4.2, 6.2, and related centers and surround speakers.
It's nice to have some Swan historians out there to aid my memory...
