I have limited space and need two polk speakers for the L/R front speakers. I already have a CS2 center, PSW125 sub and 4 OWM3 speakers for the rears and back rears. For the two fronts I was thinking of Monitor 40's or TSI200's or 2 more OWM3's . Any suggestions on those three choices or something else of similar size and not over $400 for the pair. Any info would be appreciated. This is my first home theater system I'm putting together. Thanks.
