A bit geeky, but this device enables routing of up to four amps into four speakers in any combination. Entirely passive, but has dummy loads for when amps aren’t connected to a speaker.
We all know speakers differ widely and are probably the biggest single influence on amp sound. This unit is great for making instant comparisons between speakers and cabinets, as well as exploring different combinations.
Thanks to Jim Sweet of Sweet Amps for the kind intro to this excellent product and maker.
