Blaze Audio BL118SSi-B 18-Inch 2500W Passive Subwoofer

Designed as a high-output sub-bass companion subwoofer, the BL118SS offers extended low frequency and high-level output in a tour grade enclosure.

The Blaze BL118SS is designed for low-frequency sections in multi-way speaker systems, or as a sub bass section in any sound system requiring extended low frequency response and the highest quality audio reproduction. Featuring close integration with Blaze power amplifiers and the ability to handle high power levels, the BL118SS is designed to satisfy the need for an extreme high SPL sub bass loudspeaker system.

The Blaze BL118SS utilizes a direct radiating 18-inch, 2,500W cone driver in a tuned enclosure—providing maximum output with minimal distortion and smooth extended low frequency response. The tour-tested, 21-ply Baltic Birch highly braced enclosure and 24 mm thick baffle board construction provide unsurpassed rigidity and strength and are mated with a powder coated steel grille with a high transmission ratio. The enclosure is configurable for use in cardioid or end-fire arrays.
