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.
The internal processing can accomplish everything an external processor could accomplish, but without degrading the sound quality and without putting components at risk. Before considering using an outboard processor, contact BASSBOSS customer service with your use-case scenario for assistance in setting up the internal processing to achieve your goals.
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.
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...

Ideally, you should have two cabinets facing the audience and one facing away from the audience. The cabinets facing the audience should have the same preset loaded in them. The cabinet facing away from the audience should be set to the Cardioid preset - Preset 8. The Cardioid Mode cabinet should be placed between the audience-facing cabinets for cancellation directly behind the array. 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.
