SEALED ENCLOSURES Sealed enclosures are the simplest to build.The most important part ofbuilding a sealed enclosure is to make sure that the enclosure is airtight.Using glue and some type of sealant on all seams will ensure solidconstruction and prevent air leaks.The box volume will directly impactthe performance of the speaker. Larger enclosures will provide flatterresponse and deeper bass where smaller boxes will provide a bump inthe response curve and generally higher output for greater SPL.Advantages of sealed enclosures:• Small enclosures• Linear (Flat) response• No port noise• High power handling at all frequencies• Excellent for sound quality• Extended low frequency output when compared to vented enclosures VENTED ENCLOSURES Vented enclosures vary only from the sealed enclosure in that a vent orport is added to “tune” the enclosure.The enclosures recommended aredesigned for great overall performance. Larger boxes tend to be easy totune to lower frequencies while medium and small boxes are easier totune to higher frequencies.The vented design is less linear in responsethan the sealed box but with noticeably more output at the tuning fre-quency.Advantages of vented enclosures:• Higher average output than sealed• Tuning frequency can be easily adjusted by changing port length• Deep bass response with lower power requirements• Great for high output with limited power

BUILDING AN ENCLOSURE

To work properly, the walls of the enclosure must be rigid and not flexwhen subjected to the high pressures generated by the speaker'soperation. For optimum performance, we recommend using 3/4" MDF(Medium Density Fiberboard) and internal bracing.The enclosure shouldbe glued together and secured with nails or screws. CALCULATING VOLUME Calculating volume is merely a matter of measuring the dimensions ininches and using the formula: H x W x D divided by 1728 (cubic feet).See block below.If two facing sides are of uneven length, add them together and divide bytwo to take the average. Using this number will give you the volumewithout the necessity of calculating the box in sections and adding thesections together.The thickness of the baffle material reduces the internalvolume so this must be subtracted from the outside dimensions todetermine the internal volume.The speaker itself also reduces theinternal volume.The amount of air displaced by each model is listed onthe specification sheet and should also be subtracted from the grossvolume calculation. SAFETY CARTON CONTENTS CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury.

PRACTICE SAFE SOUND™

Continuous exposure to sound pressure levels over 100dB maycause permanent hearing loss. High powered auto sound systemsmay produce sound pressure levels well over 130dB. Use commonsense and practice safe sound.• (1) Prime R2 Shallow Series Subwoofer RECOMMENDED ENCLOSURES
