Hi everyone. Currently building my first home theater system on a budget and limited knowledge . I currently have a denon avr-s910w, 2 klipsch r-28f , and a klipsch r-25c . Looking to add a sub and rear speakers in the near future but also feel like my center is a bit quiet. So basically not sure if I chose the right center speaker for my set up. Looking for some suggestions for those new speakers or even changes to the speakers I currently have. Thanks in advance for any advice!
