Polk Audio RTi4 or Monitor 50?

[WalleO]

Thanks for taking the time to look into my thread people. Im in the market looking to buy a few speakers for my setup. Currently i have a pair TSi100 for my rears and a CS10 for my center. Im looking to buy speakers for my surrounds and Fronts. For my surrounds im thinking of the RM6751 but i cant decide what i would like for the fronts. Here's my prefence: i dont want to spend more than $200 for my fronts. I also would prefer not to get anything bulky or too space consuming but at the same time i dont want to sacriface too much quality either. Is the RTi4 comparable in sound quality to the monitor 50's? Please guys leave me your input, i'll like to order within the next 24 hours. Also what would you recommed for my surrounds? i dont want to send more than $330 for my sounds and fronts. thanks for looking guys
