For the touring professional who requires full output with limited space, the BASSBOSS SSP215-MK3 is a dual 15" powered subwoofer that delivers massive low-end frequencies effortlessly, yet takes up 50% less space than the SSP218-MK3. The SSP215-MK3 is a vented direct radiating subwoofer that offers amazing versatility and practicality for those who need a lot of low end for a wide variety of applications, delivering massive output reliably, consistently, and with great fidelity.

The SSP215-MK3 is equipped with high-power long-excursion drivers in a carefully optimized cabinet that provides sufficient volume and port area to allow its 15" woofers to deliver as much depth as possible. It provides consistent output with minimal thermal compression thanks to the several effective but transparent protection systems that are part of the integrated signal processing. The SSP215-MK3 includes a Neutrik powerCON True1 TOP power cable.

MK3 Amp Update

• There are all-new amplifiers in the MK3 series. Total power has increased; however, power allocated to woofers increased substantially. The higher output voltages provide more impact. Universal input voltage compatibility of 90 to 250V provides more flexibility. Waterproof connections provide more peace of mind.

MK3 Enhanced DSP

• The MK3 features an all-new 96 kHz DSP. The push-button presets have doubled from 4 to 8, and up to 100 presets can now be stored in the DSP and loaded via LAN. The comprehensive suite of processing includes meticulously tuned equalization, all necessary high-pass and low-pass filters, and multiple protection systems and limiters to prevent driver overload in as many ways as possible.

ControlBASS Software

• ControlBASS software supports an essentially unlimited number of possible BASSBOSS-developed or customized user presets which integrate seamlessly and coherently with all other BASSBOSS products for effortlessly perfect setups. The latest in DSP programming developments can be added via easy remote updating.

• The SSP215-MK3 is equipped with extremely rugged, very high power handling long excursion drivers in a carefully optimized cabinet that provides sufficient volume and port area to allow its 15” woofers to deliver as much depth as possible. It provides consistent output with minimal thermal compression, thanks to the several effective but transparent protection systems that are part of the integrated signal processing. The multiple protection systems work independently to prevent over-excursion and thermal overload of the voice coils, and minimize long-term thermal compression. Since they work independently, reacting to different stimuli, their effect on the transient response and peak output of the loudspeaker is almost imperceptible.
• The SSP215-MK3 achieves an extremely flat frequency response, measuring ±1 dB from 35 Hz to 100 Hz. No equalization is utilized to achieve this response. Unlike designs that require equalization to achieve their specified response, the SSP215-MK3’s response is part of the cabinet design, so that the sensitivity of the speaker remains consistent through its operating range. This allows it to achieve a higher SPL at lower frequencies, using less power than systems that require bass-boost EQ to achieve their stated response. This design philosophy is how BASSBOSS subs can deliver more SPL at lower frequencies without needing more power.

• The cabinets are made from 18mm birch plywood, are extensively braced, and feature four ergonomic recessed handles. They are coated in weatherproof high-pressure polyurea, and the drivers are protected by a powder coated perforated steel grille. The cones also feature a waterproof coating.
• Versatility is one of the SSP215-MK3s greatest strengths. The performance of the SSP215 can be compared to almost any double 18” sub on the market but will fit where they don’t. Taking up 50% less space than the SSP218, and delivering almost the same sound levels over very nearly the same frequency range, the SSP215 allows big sound to be hidden in small spaces. If you need a serious sub to fit under a low stage, or need to fly a sub under a low ceiling, this is it.
• The enclosures feature four large rubber feet and corresponding recesses in their tops to facilitate interlocking the boxes when stacked. They share the same footprint as the SSP218, so the feet also interlock with available wheel carts, allowing multiple boxes to be stacked on a cart for rapid deployment with minimal effort. The stacked set’s footprint measures 29.5” x 48”, making it easy to fit them securely in almost any commercial truck. The carts can accommodate up to 5 subwoofers, allowing for extremely tight truck-pack density. Five-, four-, or three-high stacks or three-high cardioid stacks can be preconfigured on carts, ready to roll in and rock.

The SSP215-MK3 features a 5000W amplifier with an autosensing globally compatible power supply that can run on input voltages anywhere between 90 and 250V. Full output power is available on anything over 110V. The amplifier's peak output voltage provides for intense high SPL hits, while its sustained output is unparalleled in its ability to deliver the liquid lows. The amplifier is passively cooled via its external heatsink and by woofer-generated airflow through the port. When necessary, two large axial fans will engage to provide additional forced-air cooling capacity in more extreme conditions.

• Dual 15" woofers with neodymium motors and massive 4" voice coils
• Neodymium magnets provide higher intensity and efficiency, resulting in a lighter and louder cabinet than those with ferrite drivers

The comprehensive suite of processing includes 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 that can be used to control the cabinets from a computer or to load software or firmware updates. The Ethernet connectivity in conjunction with the DSP board allows signal to be sent via Milan AVB. Firmware updates will provide access to this feature.
• 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 and yet 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 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 Top Boxes and are also compatible with previous generation tops and subs.

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

Q: 1. can I connect it strait to Sony tv?

A: No - it needs to connect to a dedicated subwoofer output.

Q: 2. Can you adjust the angle of the mirror?

A: Yes you can.

Q: 3. I'm planning to use this SSD to record raw video in the Blackmagic Cinema Camera 2.5k. I'd like to confirm that the MK3 it's capable of doing that flawless without dropping frames, because the one in BMD approved list's for BMCC 2.5K it's the previous model, MK2. Thanks! ?

A: If the Mark II model worked, we believe this Mark III should work as well. Please keep in mind that Blackmagic has not updated that list since 2017, they have not tested more recent releases with the Cinema Camera 2.5K.
