BB15 MK3 Technical Overview

BASSBOSS continues to push the envelope of design for the “most bass out of the least space” mobile-optimized subwoofers. The BB15-MK3 subwoofer’s compact size and excellent output-to-price ratio were designed for gigging DJs, home studio bass-heads, or venue owners with limited floor area.

A powerful, easily portable system that delivers superior sound quality, the BB15-MK3 offers remarkably deep bass for its size. An integrated DSP facilitates plug-and-play ease of use while a 2500-watt amplifier and a 4.5” coil neodymium woofer make the compact, lightweight design extremely effective at rockin’ the house. Although only 21” x 17” x 24” and 71lbs, its output SPL and low-frequency extension capabilities exceed many larger subs.

The BB15-MK3 is the smallest, lightest, and most effective solution for DJs and venues seeking high levels in tight spaces. Perfectly capable of providing high SPL starting from 40Hz, there’s barely any event this little box can’t do. When you want the biggest output from the smallest sub, the BB15-MK3 is your go-to sub.

The BB15-MK3 is a single 15-inch direct-radiating subwoofer featuring a long excursion woofer loaded into a vented enclosure that is tuned to optimize low-frequency output using a large port. The amplifier is loaded at the interior port end to utilize the airflow at high output for additional cooling.

The BB15-MK3 features a 2500W amplifier with an auto-sensing, globally compatible power supply that can run on mains supplies between 90 and 250 Volts. Full output power is available over 110 Volts. The amplifier’s high peak-output voltage provides for intense high SPL hits, and its sustained output is unparalleled in its ability to deliver the punchy lows. The amplifier is passively cooled via its external heat-sink and by woofer-generated air-flow through the port. When necessary, two blower-fans will engage to provide additional forced-air cooling capacity in more extreme conditions.

Electrical power is converted into the much more desirable acoustical power by a robust, neodymium motor, 15-inch woofer with a massive 4.5-inch (115mm) copper-wound voice coil. Neodymium magnets are lighter, and their higher intensity provides increased efficiency, resulting in a lighter and louder cabinet than those with ferrite drivers.

New to the MK3 are Neutrik powerCON True 1 TOP (Total Outdoor Protection) waterproof mains connectors. These waterproof connectors coupled with a totally isolated input connection section and cones that are waterproofed make the MK3 series powered loudspeakers able to be used outdoors without fear of what the weather will bring, or used indoors without fear of what the partiers bring!

The MK3 features an all-new DSP with a comprehensive suite of processing including high-pass and low-pass filters, as well as multiple protection systems and limiters to prevent driver overload in as many ways as possible, including thermal, excursion and clipping. The five levels of protection actively prevent overheating of the voice coil, minimize long-term thermal compression and limit excursion. Because they operate in 5 different modes, the limiters are sophisticated enough to have a largely unnoticeable effect on the transient response and allow the subwoofer to deliver peak output safely.

The new DSP features an Ethernet interface. This can be used to control the cabinets from a computer or to load settings updates. Within the software, multiple cabinets can be grouped together, allowing them to respond to commands simultaneously. This permits the levels of multiple loudspeakers to be adjusted together as well as independently from the levels of other groups of loudspeakers. In addition to individual and grouped level controls, presets can be loaded and signal levels and temperatures can be monitored. Each cabinet includes a two-port switch so multiple cabinets can be chained on the same data cable.

The MK3 DSP features a storage capacity of up to 100 presets, eight of which can be accessed at the touch of a button with no need for a connected computer. The eight directly accessible presets are compatible with all the presets in the MK3 products and are also phase compatible with previous generation tops and subs.
