RECOMMENDED ENCLOSURES

Diamond's M6 Series subwoofers are primarily designed for use with small sealed
enclosures. Good results have also been achieved in vented and bandpass
enclosures. Although “free-air” (infinite-baffle) applications are NOT recommended,
they may be used successfully in low-power systems (e.g., 75W or less per sub).
HIGH PASS ("SUBSONIC") FILTERS MUST BE USED WITH NON-SEALED APPLICATIONS
TO PREVENT OVER-EXCURSION AT INFRASONIC FREQUENCIES.
The enclosure volumes shown below are NET INTERNAL VOLUMES. Driver, vent and
brace displacement must be taken into account when designing your enclosure.

The installations and enclosures shown in this manual are offered as a suggestion
only. Since enclosure design is as important to sound quality as the speaker itself, it
is recommended that your Authorized Diamond Retailer assist you in designing and
building an enclosure to suit your vehicle. For more information on selecting the
best subwoofer enclosure, consult the "FAQ" page of our web site,
