Recommended power ratings
Polyglass subwoofers are already highly efficient, with improved sensitivity. Therefore, their use
with amplifiers will produce comfortable listening pleasure. However used in a more high-end
system, with more powerful amplification, the audio quality will be greatly improved. It is very
important to check that rated power of the amplifier is suitable to the subwoofers. Otherwise they
may distort, or possible damage could occur. Always consult the owners manual of the principal
source (head unit/amplifier), to ensure the power rating is compatible. A safe guide is to ensure
the maximum power of the amplifier is not greater than the nominal power of the speakers.
