Sold Out $3,099.99

The Diamond 11.5 is the flagship floorstanding speaker of the Diamond 11 Series — a three-way tower for large rooms and serious listening. Twin 8" (200 mm) woven Kevlar® bass drivers, a 4" (100 mm) Kevlar® midrange and a 1" (25 mm) textile-dome tweeter reach a deep 28 Hz bass extension.

Its large dual 8" bass section and separate 63 L and 10.7 L chambers deliver authoritative low end, while crossovers at 640 Hz and 3.5 kHz keep the midrange and treble clean across a 35 Hz – 20 kHz response and a 102 dB peak SPL. At 90 dB sensitivity and 8 Ω (3.5 Ω minimum), it makes the most of amplifiers from 25 to 200 W. Each speaker weighs 27.1 kg.

It is the most powerful speaker in the Diamond 11 Series; the 11.4 offers a similar three-way design for smaller rooms. Browse all our floorstanding speakers.
