• What are the dangers with running amps of a higher power rating than your speakers? Giving some consideration to buying a pair of Crown XLS 1002 power amps, the YouTube hype kit of the moment, bridged as monoblocks to run those Klipsch Heresys, plus a subwoofer if there’s any money left when work returns to normal.

    All reports say that those speakers work well with minimal power due to their 99dB sensitivity but I have 50wpc driving them and I feel like they have a lot left to give with more oomph. I’m turning it up beyond 12 o’clock regularly and the sound improves a lot.

    So will I kill them or will it be so unbearably loud before danger sets in that I’m unlikely to get there?

  • 99db/w/m is very high sensitivity.

    99db is loud

    Remember that an increase in 10w is a doubling of loudness.

    You could drive them to uncomfortable levels with a handful of watts.

    Consumer amp ratings are mostly about marketing and dick waving.

  • Yep. Agree about willy waving.

    I have 50w per channel with 87dB and they go very loud without clipping in a fairly normal room.

  • Also the amp I’m using is approaching 20 years old so might be in need of some component refreshing.
