Members girevik Posted April 12, 2007 Members Share Posted April 12, 2007 If a speaker is rated at 135W peak power handling and 45W continous power, and a cabinet has 6 of these speakers, does it mean the speaker cabinet has a peak power handling rating of 135W x 6 = 810W?

Members agedhorse Posted April 12, 2007 Members Share Posted April 12, 2007 Just be sure you understand the manufacturer's definition of peak. MOST are pretty optimistic. What driver is it? The cabinet type and bandwidth will also affect the power handling. Link to comment Share on other sites More sharing options...

With the given speaker specs, is it reasonable to calculate total power handling (continuous, not peak) by adding the wattage of the speakers together? This would apply to all speakers, regardless of application, right? That's the info I'm trying to gather. Thanks! Link to comment Share on other sites More sharing options...

Just multiply it by the number being used. Link to comment Share on other sites More sharing options...

Nope, not a trick question. Your previous answer was about peak power handling, so my followup question was about continuous power handling. I asked because I honestly didn't know and wasn't sure if continous power handling had to be calculated differently. Thanks! Link to comment Share on other sites More sharing options...

I asked because I honestly didn't know and wasn't sure if continous power handling had to be calculated differently. Thanks! Here you go dude. Peak = 4 x RMS = 800 Continuous Program Power = 2 X RMS = 400 RMS = 200 Add whatever wattage you like where I started from 200 and start multiplying. Just remember once you go beyond Continuous Program Power, you are more likely to kill your speakers. Only those that know what they are doing venture outside Continuous Program Power. PS I know RMS is not the right term, but it's the most used. And, I'm going to bed. Link to comment Share on other sites More sharing options...
Members agedhorse Posted April 13, 2007 Members Share Posted April 13, 2007 Yes you will add up the respective power. I would power them with an amp rated at no more than the "continuous" rating... that would be an amp that delivers 45 watts into a 4 ohm load, or if 2 are paralleled that would be 90 watts into a 2 ohm load. You will probably need to arrive at a higher impedance by a combination of series and parallel connection to limit the power to those little guys.

CMS Author Craig Vecchione Posted April 13, 2007 CMS Author Share Posted April 13, 2007 $600 for that? Subtracting the cost of the speakers, that MDF box is almost $300. Link to comment Share on other sites More sharing options...
