REL T/5x

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

REL T-series entry. High-level connection from speaker terminals preferred for music systems.

Competition record

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