Martin Audio Blackline X115 15" Passive Subwoofer

The Blackline X115 is a portable single-15 subwoofer designed to extend the low end of the Blackline X tops. A single 15" (380mm) long-excursion driver in a reflex plywood cabinet gives it useful output below 45Hz while staying light enough for one person to load, which makes it a popular sub-and-top pairing for mobile DJs, bands and event crews.

It handles 500W AES (2000W peak) at 8 ohms and reaches 135dB peak (half space), with response down to 40Hz (-10dB). A 35mm pole socket takes an X10 or X12 directly on top, M10 flying inserts allow suspension, and it accepts castors for rolling in and out. Three NL4 connectors handle through-wiring in a stacked system.
