JL Audio 8W3V3-4: 8" 250 W RMS 4-Ohms W3V3-Series SVC Subwoofer
About the JL Audio 8W3V3-4: 8" 250 W RMS 4-Ohms W3V3-Series SVC Subwoofer
If you need an 8" Subwoofer that can create outstanding bass in extremely small enclosures, the 8W3V3-4 will do the job and surprise you through its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.4" (10 mm) of controlled, 1 way, linear excursion.
The 8W3V3-4 is best used through amplifier power in the 75 - 250 W range and is optimized to operate in a tiny 0.3 cubic FT (8.5 L) sealed enclosure, or a 0.4 cubic FT (9.9 L) ported enclosure.
Enclosure notes:
- The enclosure recommendations listed above are external dimensions which assume the use of 0.8" (19 mm) thick material. If you are using 0.6" (16 mm) thick material, subtract 0.3" (6.5 mm) from each dimension. Do not use any material through a thickness of less than 0.6" (16 mm) as this may compromise the rigidity of the enclosure
- All enclosure volumes listed above are net internal volumes! Driver, port and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account
- When using multiple Subwoofers in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or technical support
- We recommend the use of this speaker in a bi amplified system using high quality satellite speakers and an amplifier. We do not recommend the use of this Subwoofer through a passive crossover (coil), as this type of device will adversely affect performance
- All specifications are subject to change without notice
Safety notice:
- Prolonged exposure to sound pressure levels in excess of 100 dB can cause permanent hearing loss. This high performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity
- When installing a Subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle through large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van
