MJ Acoustics Oxford

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

Entry to MJ Master-Class Series — represents "new approach to subwoofer design" per MJ marketing. Master-Class adds: balanced dual driver configuration potential (Kensington), double-height sealed cabinet, glass base plinth, dual digital displays.

Oxford specifically uses single 10" driver in double-height sealed cube — Master-Class entry-tier configuration. Hand-matched components per channel; technicians individually responsible for build and test of each Oxford.

For 102m³ room: appropriate primary sub at upper-mid tier where visual integration with audiophile systems matters. Master-Class aesthetic (glass plinth, dual displays) suits high-end visual environments more than utilitarian Reference Series cube.

Competition record

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