No kidding.  Good dealer and almost perfect timing (you got the use of the III for a month plus your wait time for the IV's).
As a current owner of Forte IIIs, I'd be curious about crossover improvements in the IVs. 

I've considered the Forte III upgrade kit from GR Research, it includes upgraded crossover, bracing and damping. 

The crossovers requiring soldering, however, which is not a skill i possess. 


They did a great job of keeping it quiet while they were working hard on the Forte IV...   mine arrived today,picking them up in the morning.
