My school has 2 different sets of speakers. We have 2 Peavey 400 watt speaker cabinets, and 4 JBL 250 watt speakers. None of these are powered. I just got the hardware today to run the JBL speakers, and I'm not sure if I should use them in place of the Peavey's. The reason why I'm wondering is because we only have a 250 watt amp. So, I am not sure if it would be better to run stronger, bigger speakers at 150 watts less then they should have, or run the JBL's at there correct wattage. Also, the JBL's are set up so that the the output of one of the speakers can go to another speaker. If I did this, would I need double the wattage of the amp, or would the same 250 watts run down the line to the secound speaker in each chain. I'm not sure i'm explaining this very well, so let me attempt to draw a diagram: ----- l.......l ---------l_l-----------------l_l l.......l l____l----------l_l-----------------l_l Amp.........Speaker 1..........Speaker 2 I hope that diagram helps (and works).
