Speaker wattage rating

Speaker wattage rating - 03/04/03 01:14 AM

My Paradigm Monitor 5's are rated to 175 watts, and my Mini Monitors (surrounds) are only rated to 100 watts. Does this mean that I would damage them if they were paired with either the Outlaw monoblocks or the 755?? Or would that only be a problem if I ran them above reference level or higher? Thanks

I wouldn't worry about that. Although it may seem counter intuititive, you are more likely to damage a speaker by using an underpowered amplifier than an over powered one. This is because an underpowered amp might be driven into clipping. When this happens, the resulting waveforms are extremely rich in high frequency harmonics which can damage the tweeters in your speakers. As long as you keep the volume within less than ear bleeding levels, you probably are quite safe using your speaker combination.

Are the Paradigms 4 or 8 ohms? If they are 4, that might be a stretch giving them 300 watts, the surrounds especially, but it is doable if you're careful with the volume. I have used the monoblocks on Bose 301s (150 watts RMS input). They had 200 watts put into them. It didn't hurt them a bit as I played at very loud volumes. This was a workout unit I took to the gym. Yeah, I got a workout going to the gym too. Many people here would not believe the bass that the amps were able to generate from them. I have never heard any Bose sound like that before.

I've driven speakers rated 150 watts with over 600 watts of clean power for hours without damage. YMMV, but the only speakers I've managed to break were (1) tweeters due to clipping (not enough power) and (2) a woofer from over-excursion (to much power at a very low frequency), other than that, more power is safer in my experience.
