User manual FOCAL ACCESS SUBWOOFERS

[. . . ] Inverted mounting helps increasing the volume for the given space available. When choosing inverted mounting the phase must be inverted (thus swap the positive / to negative connections) so that the polarity is correctly observed. Multi-subwoofer installations To obtain a more powerful acoustic presence, we recommend the introduction of multiple subwoofers for your chosen installation. Using multiple subwoofers, various series or parallel or combinations of both can be used, but always check the specifications of the power source (amplifier) before attempting any installation. [. . . ] Damping material (foam etc) covering all the internal walls of the enclosure, will further ensure it is free from unwanted resonances. It is imperative that your custom designed subwoofer enclosure remains securely mounted at all times to the vehicle. The improved power handling has allowed Focal subwoofers to play at very loud sound volumes. For this reason, we recommend caution be wisely applied, especially during long listening periods. Excessive volume levels of more than 110dB can cause permanent hearing damage. 4 Access Subwoofers Manual Recommended power ratings Access 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. 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. Guarantee All Focal loudspeakers are covered by guarantee drawn up by the official Focal distributor in your country. Your distributor can provide all details concerning the conditions of guarantee. Guarantee cover extends at least to that granted by the legal guarantee in force in the country where the original purchase invoice was issued.
