Good to know
- The top has an M20 thread, so you need an M20 speaker pole (for example the Mackie SPM400) to mount a speaker above it.
- The high-pass outputs send everything above the crossover to your top speakers, so they do not have to work on deep bass.
- At about 30 kg, plan for two people to load it.
FAQ
Can I use two Thump118S subwoofers together?
Yes. The stereo or mono summing switch is made for single or dual subwoofer setups.
Which voicing mode should I use for DJ sets?
Mackie suggests Deep for dance, rap and electronic music, and Punch when you need the highest output for bands and rock.
