Okay...let's say I wanted to replace my F-3 speakers. I really like my F-3 speakers, but I'm having a custom media cabinet built in my basement that is going to run the entire length of the wall. The F-3's are huge in both depth and height. This is really causing me to think about replacing them with Bookshelf speakers. Bad idea? If it seems reasonable, what line would be recommended for under 500 bucks for the pair. Would getting a set of RB-61 II speakers be better quality, lower quality, same quality toward my overall HT setup. On paper, my F-3s kick their butt. But what's on paper isn't everything....and I'd be saving a lot of space in my cabinets. I am also really anoyed the F-3s aren't completely square haha. They are also listed as 16" deep but they are really about 18" with the grilles on. Looking forward to hearing more opinions, thanks!
