Does anyone out there know if AV 123 changes their prices fairly regularly, or if they stay the same from month to month. The reason is that I am slowly working up the bank for a complete 7.1 system, but it is going to be some time (early to mid 2003). If anyone has purchased the Diva's in the last 2 years, and wouldn't mind telling me what they spent, that'd be awesome . What I want to get is 6.1's for the front, 2 pairs of the R-3's for the rear surrounds and centers, and the C3 for the center front. Next, regarding driving the R-3's particularly, can anyone tell me how much, if any, they had to cut the output to the rear surround channels assuming you have the same output to all channels. I suppose I don't really understand having rears rated at 4 ohms, unless it is to make up for some amp manufacturers building lower rear amp output which few seem to do any longer. Does anyone know if the R3's might be upgraded to 8 ohms some time in the future? If anyone has any input, I'd appreciate the info.
