MJ Acoustics Pro 80 MkI

Subwoofer

Relative price

below typical

Among the 24 subwoofers in the catalogue, this one is below 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

Mid-Pro tier music-focused — appropriate for medium-large rooms; for 102m³ room: workable as primary sub at this tier, may pair well with smaller monitors (P3ESR-XD2, Falcon Q7) where larger subs would overwhelm.

Class A/B MOSFET preserves MJ brand DNA tonal warmth.

D.A.M.P 2nd-generation — predecessor to the 3rd-generation D.A.M.P in Reference Radial series (802/805/800 Mk2).

Competition record

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