Important Notes:
- Watts: The guaranteed long term power rating throughout the usable frequency range of the speaker. (Translation: the speaker will operate continuously at any frequency within the speakers specified frequency range when driven at this power. The "Watts" rating is similar to RMS, but is really more indicative of long term thermal capability.)
- Music Program: The speaker will safely and reliably handle the varying frequencies of musical content at this power rating. The "Music Program" rating is more indicative of what you can expect in the real world with the speaker operating within the appropriate enclosure reproducing music or vocal audio program.
