SPL = More overall output and compact enclosure size, but sacrices some low bass and smooth overall output
Normal = Recommended for most listeners. Excellent blend of low bass, accurate and strong overall output
SQ = Smooth and exceptional low bass output, but larger enclosure size and sacrices some overall output
Additional Notes:
• For vented enclosures a subsonic lter set at 30Hz to 40Hz is highly recommended.
• Sealed enclosure volumes INCLUDE THE DISPLACEMENT of the subwoofer.
• Vented enclosure volumes INCLUDE THE DISPLACEMENT of the subwoofer. But DO NOT include
displacement of the vent.
• In many cases, a 4 inch round vent/port can be used instead of a rectangle/slot vent. This can reduce the vent
length and simplify the enclosure construction. However, in some rare cases at high power a small amount of
port noise maybe audible. The provided slot/rectangle ports will provide maximum performance and the most
predictable results. Contact technical support for additional enclosure options.
