*Power ratings alone cannot predict actual sound output. Loudspeaker efficiency is by far the most important factor in determining how loud your system will play. For this reason we also specify the calculated maximum sound output of the RMDS-1 system in a 2825 cu ft. room (for example, one measuring approximately 15'W x 22'L x 81⁄2'H). The maximum SPL (volume) of the RMDS-1 in such a room would be 105 dB, as loud as

a rock band at 150 feet; certainly loud enough to get you evicted from a New York City apartment. There are worse fates.
