Hi all,   What amp would you recommend for 2 pairs of  Polk Audio RC60i In-Ceiling speakers and/or a single pair of RC60i's. I'm looking for an amp that has good value and preferably something I can purchase on amazon.   Recommended Amplification per channel is 20 - 100 wats   Thank...

Hi all,   I'm looking for decent ceiling speakers for a classroom. Preferably speakers that sound good but also have a reasonable price point. I was looking at the Polk Audio RC80i's but I'm not too sure if they're a good buy.   Any input is appreciated, Thanks
