This superb bass enclosure is made from 13 ply high density 18mm birch
plywood, with tough skids on the base of the cabinet for enhanced stage
protection. The skids also act to couple the enclosure to the floor, thereby
increasing bass response. Internally, the enclosure is acoustically
compartmented for strength and anti-vibration. The OBC115 is side-ported,
allowing for speaker
self-correction.
