Celestion c90 90w 8 ohm mesa b. 7635

celestion custom 90 (an english made mesa exclusive) used in open back cabinets and our widebody closed back cabinet. the c-90 (also often referred to as a black shadow or mc-90) bestows upon cabinets a tight e controlled low-end, abundant high bass e low mids, authoritative mid-range attack and an assertive yet composed top end. it is superb at cutting through the mix while not being piercing. a favorite of lead guitarists for its 90 watts of headroom, its voice and dynamic response. this speaker is best suited for open back and ported, closed back cabinet designs due it its thick e robust low end and not one we tend to recommend for strictly closed back cabinets.

this speaker ships individually in its own box.
