18” subwoofers in combination with the hard hitting punch of horn loaded subwoofers. The VS21-MK3 brings the world of extended low frequency together with the world of high-impact: You’re no longer forced to choose either deep OR punchy, as the VS21 offers both. - Page 3 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. bassboss.com 3...

Provided the cabinets are physically aligned, any BASSBOSS sub can be combined with any BASSBOSS top and their outputs will be phase-coherent. This means no cancellations and no gaps in the response at the crossover frequency, regardless of which preset is selected. -
Page 5: Outboard Processor Warning
Outboard Processing Warning Third-party outboard processing (Drive Racks, etc.) are not recommended and are not necessary with BASSBOSS MK3 series powered loudspeakers. Outboard processing will not improve, and will very likely degrade the sound quality, reliability and output capacity. Using external processing inappropriately can cause driver damage that is not covered by warranty. -

1. Each preset includes all necessary low-pass and high-pass filters at the selected frequencies and all the necessary alignments to maintain phase coherence in the crossover range when used with other BASSBOSS powered speakers. Presets help you fine-tune the balance between the subwoofers and top speakers. More details on the different combinations are on page 7. -
Page 7: How To Use The Presets
It’s recommended that you try several, if not all, combinations when first setting up to determine which combination works best in each environment. You will likely choose different combinations for wood floors, concrete floors and outdoors. Experiment with different combinations to dial in your preferred combination in different environments. bassboss.com 7... -

Page 9: Power Distribution
Connect no more than one 5000W or two 2500W subwoofer amplifiers to a single 20A circuit. If you need to share circuits don’t exceed two BASSBOSS single-driver subwoofers or one double-driver subwoofer along with one or two top speakers on the same circuit. -
Page 10: Cardioid Mode
The main subwoofer cabinets face the audience and use one of the first 7 presets, while the cardioid cabinet faces away from the audience with Preset 8 selected. When two cabinets are facing forward and one is facing backward in cardioid mode, set the input levels the same for all cabinets, with the same signal going to all. When one cabinet is facing forward and one is facing backward in cardioid mode, set the cardioid cabinet’s level 6dB lower than the forward-facing cabinet, with both cabinets receiving the same signal. If there’s only one cabinet facing forward and another one facing backward in cardioid mode, you can place the cardioid cabinet on top of the forward-facing cabinet. If you place the cardioid cabinet next to the forward-facing cabinet, position the forward-facing cabinets further away from the stage or the area where you want to reduce sound levels. The most significant sound reduction happens along an imaginary line drawn from the center of the forward-facing cabinet’s woofer back through the center of the cardioid cabinet’s woofer. How and When to Use Cardioid Mode Cardioid mode doesn’t make the sound louder for the audience. Instead, it reduces the bass level behind the subwoofer stacks. When you have two subwoofers facing the audience and add a third one in cardioid mode, the sound level in front of the two subwoofers won’t change much. However, the sound level behind them will decrease. In some situations a wall or structure may reflect the sound radiating from the rear of the subwoofers back towards the audience. That reflected sound can cause phase cancellations leading to a loss of impact and uneven frequency response. Cardioid mode can help eliminate those cancellations before they happen, leading to better sound quality and impact for the audience.
