I just left my local HT place and the sales guy did not recommend mixing my Polk LSI 9's and a Monotor Audio Bronze Center channel speaker because the sound would not match. I held off on buying them. SO, my question is: Would getting another center from Polk such as the C3i work? It is fairly affordable. The best thing for me to do is save up for the LSi center speaker. Your thoughts are appreciated. I have the LSi 9's HK AVR 330 and Klipsch R8 Sub in a medium sized room with hardwood floor. thanks for reading.
