Celestion Ruby

The Ruby is an alnico-magnet guitar speaker that’s purpose-built to

create vintage tones – and at 35-watts power handling, it’s ideal for

use with mid-powered amps and combos. Bringing the instantly familiar

Celestion alnico vibe with its glorious, dampened attack; the Ruby oozes a

richly musical vintage warmth, with mellow highs and a smooth,

sophisticated midrange.
