INSTALLATION

Thiele/Small data and suggested enclosure volumes for Diamond CM3 Subwwofers are shown below. The enclosures specified here 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, visit www.diamondaudio.com Diamond's CM3 Series subwoofers are primarily designed for use with small sealed enclosures. Good results have been achieved in vented and bandpass enclosures also.

HIGH PASS ("SUBSONIC") FILTERS MUST BE USED WITH NON-SEALED APPLICATIONS TO PREVENT OVER-EXCURSION AT INFRASONIC FREQUENCIES.
