Speco Technologies Top Hat Back Can for 8″ Speaker Combinations

The STI SpecSeal® 8″ FireStop Ready Sleeve — correction: Speco Technologies Top Hat Back Can for 8″ Speaker Combinations (STH8) — is a durable speaker enclosure designed to protect and support 8-inch ceiling speaker installations in commercial audio systems. Constructed from heavy-gauge steel, this back can shields the rear of the speaker from debris, dust, and environmental disturbances while improving acoustic performance.

The enclosure includes perforated mounting straps and four J-clips, allowing technicians to easily mount compatible 8-inch speaker and grille assemblies. Its undercoated interior helps reduce vibration and mechanical resonance, which can improve sound clarity in paging and distributed audio systems.

Designed for installation in ceilings or walls, the STH8 features combination knockouts for conduit entry and a rust-resistant finish for long-term durability. This makes it ideal for commercial audio systems, paging installations, retail environments, offices, and public buildings where reliable speaker protection and performance are required.
