MJ Acoustics Pro 100 MkII

Subwoofer

Relative price

typical

Among the 24 subwoofers in the catalogue, this one is typical.

A band places a component against its peers and carries no price. It is deliberately the only price indicator on this page: a second one, measured against a different set, would narrow the two together far enough to give the figure away.

What it is

Per Origin Live retailer: "delivers vast punch and solid slam without the dreaded overhang down to a gut-wrenching 10Hz" — MJ marketing.

Pro 100 MkII has been in production since ~2020; long-running design. No remote/Smart Remote (vs Reference series Smart Remote feature).

Competition record

Assessed against 3 rivals across the sixty systems: it takes the slot in none of its 15 head-to-heads.
