Your ESB subwoofer is a precision loudspeaker that has been designed to
produce very high-quality sub-bass frequency performance in your car. To
maximize the performance of your speaker we highly recommend using a dedicated
enclosure. Inside this manual, you will find specifications and two
recommended enclosures for your speaker: one is a sealed enclosure, and the
other is a ported design. Both types of enclosures will give you excellent
sound quality and low-frequency extension. The sealed enclosure is a better
choice if the space is extremely tight, but the ported enclosure will produce
3dB more output at the same power if you have the extra space to work with.

Recommended Sealed Enclosure
- Volume (include speaker displacement): 0.635 ft3/ 18 lit.
- External dimension (W,H,D): 16.73×11.81×9.44″ / 425x300x240 mm
Note: Dimensions are assumed with 3/4″ material (19mm).
This is the suggested thickness. Less thickness may compromise box rigidity
with leak bass response.
Add inside the damping material for about 75% of the volume.
Recommended Ported Enclosure (Reflex option A)
- Volume (include speaker displacement): 0.741 in3 / 21 lit.
- External dimension (W,H,D): 19.49×11.41 x10.23″ / 495x290x260 mm
- Reflex port dimension (R1,R2): 10×0.787″ / 254×20 mm
- Reflex port length (L1,L2): 8 74+6.61″ / 222+168 mm
Recommended Ported Enclosure (Reflex option B)
- Volume (include speaker displacement): 0.741 in3 / 21 lit.
- External dimension (W,H,D): 18.11×11.41×10.23″ / 460x290x260 mm
- Reflex tube internal diameter (ID): 3.07″ / 78 mm
- Reflex tube length (L): 14.48″ / 368 mm
Note: Dimensions are assumed with 3/4″ material (19mm). This is the suggested thickness. Less thickness may compromise box rigidity with leak bass response. Add inside the damping material for about 35% of the volume.
