BassBoss Sublim8 MK3 Description

BassBoss Sublim8 MK3 brings the output and depth of a professional PA system into a streamlined column speaker format. Designed for mobile DJs, lounges, bars, houses of worship, schools, event centers, and corporate events, it delivers powerful bass, clean mids, and crisp highs from a visually understated system that sets up quickly.

The tri-amplified 4000W Class-D amplifier provides 2400W to the 18" subwoofer, 800W to the dual 8" midrange section, and 800W to the 3" compression driver. This driver configuration produces a 35 Hz to 19 kHz frequency response and up to 133 dB SPL, giving the system enough output and headroom for demanding small to medium venue applications.

The top section uses dual 8" midrange drivers and a 3" horn-loaded compression driver on an isophasic waveguide, delivering wide 120° horizontal coverage with controlled 20° vertical dispersion. The result is consistent, intelligible sound across the audience area while helping reduce unwanted floor and ceiling reflections.

The system is built from CNC-machined birch plywood with extensive bracing and dado joinery for durability and acoustic strength. A high-pressure bonded polyurea coating, perforated powder-coated steel grilles, integrated handles, and bottom wheels support professional mobile use.

The BassBoss Sublim8 MK3 also includes comprehensive 24-bit / 96 kHz DSP with equalization, phase alignment, high-pass and low-pass filters, and multistage limiting. Eight push-button presets are available directly from the system, with storage capacity for up to 100 presets.
