Ok I went down to Tweeter. Listened to the RB3 and the RF3II and came away quite impressed with the bookshelf model. Now I also understand the RB5 has an 8" woofer compared to the RB3 which has a 6.5" woofer. Has anyone auditioned these two bookshelves, and what were your impressions? Unfortunately, Tweeter only has the RB5 as a special order item, and I could not find another to listen to. Also, I plan to pair these new fronts with the RC3II center channel and a Denon 3803.
