SEALED ENCLOSURE
The sealed enclosure combines three key aspects of a subwoofer box design:
- Audiophile sound through natural low frequency roll-off and tight bass;
- Extremely compact footprint design;
- Ease of construction and absence of air turbulence typical of duct/port
tuning in reflex designs.
ML 2500.3
SEALED - COMPACT (17 LITERS - 0.6 CUBIC FEET)
Best performance / space ratio. Enclosure size similar to that of a side
trunk installation.
ML 2500.3
SEALED - PERFORMANCE (25 LITERS - 0.88 CUBIC FEET)
Suggested for a tight yet solid audiophile bass. Use of subsonic filter is
advisable for clean reproduction in the lower range (10Hz - 24 dB Oct.).
