Dear All, I have a little knowlegde on Audio System. I did search and learn from Google, but I still not have answer for following question and I am really need your help: + MRA amplifier just have power rating of 25W. How can they match with Clipsal speaker of 60W? As google says: - if speaker have lower power rating, it can be hamfull - if amplifier have lower power rating, speaker may not reproduce some freqencies. + How big a room that 25W MRA amplifier can provide audio with good quality and sound volume? + I connect 4 x 6W ceiling speaker? Is this work well? Thank you very much for your help! BigBoyVn
