I'm looking to replace some old onkyo speakers from a htib i bought almost 10 years ago. I already have a rhythmic audio lv12r subwoofer and a denon 2313ci. My room will be pre-wired for every channel except for the center (which I can probably do myself). The wires are near the roof so the speakers are mounted near the roof. I am hopping that i can find a bracket or something to angle the speakers downward. Anyway, that means floor standing front speakers are going to be a problem and I need to go with bookshelves. I was browsing around and I came across the pioneer speaker set SP-PK52FS. However since it is only 5.1 and has a sub/floor standing speakers it won't exactly work for me. I then set out to try to piece together a set of speakers that I thought would compare. I opted for the same center channel and 3 pairs of the bookshelves for front, surround, and rear channels. is there any problem with using 3 pairs of identical speakers like this? Can you come up with better options ?
