Bookshelf Speakers — Triangle Signature - Theta

The Signature - Theta is a bookshelf loudspeaker from Triangle, part of the brand's flagship Signature series, built with notably high sensitivity and a wide amplifier-power tolerance. The Signature - Theta brings Triangle's most accomplished current engineering to a substantial compact stand-mount format.

Key specs that matter

Rated response is 45Hz to 22,000Hz within plus-or-minus 3dB. Sensitivity is a notably high 90dB into the standard 8 ohm load, with a wide recommended amplifier power range of 25-130W. At 23.3 x 46.5 x 37.2cm and 11.5kg, the Signature - Theta's considerable weight for a bookshelf design reflects Triangle's flagship-tier internal driver and cabinet engineering.

Sound and use context

Expect the refined, musically engaging character Triangle's flagship Signature series is broadly known for, with the notably high 90dB sensitivity providing genuine dynamic ease across the wide power tolerance.

Pairing

The standard 8 ohm impedance and wide 25-130W recommended range suit a broad selection of amplifiers.

Alternatives

Triangle's own Borea - BR08 offers genuine floorstanding scale within a different, more accessible series.
