• A double-wall sealed enclosure tuned for the best impulse response.
• Internal enclosure of cylindrical shape made of a dense cellulose tube. Just as in the case of a submarine, a "cigar-like" shape can resist much higher pressure than a rectangular shape. In addition, due to this shape there are no standing waves.
• External enclosure of 13/16" (20mm) MDF. Dual layer, pyramid-shaped back wall to prevent any possible resonance.
• The space between both walls can be filled with sand or lead shot therefore completely eliminating any enclosure vibrations.
• Specially selected 15" woofer with dual voice coils delivers a much better damping factor ?a key parameter for a subwoofer.
• Dual, all brass, gold plated posts, accept banana plugs or up to 2 AWG wires.
• Filled with 100% natural long hair wool for fine-tuning.

Specifications:

• One 15" dual coil driver in sealed, dual wall enclosure.

• SPL: 90 dB 1W/1m
• Impedance: 4/8/16 Ohms
• Dimensions: 18" H x 18"W x 19.4" D (45,6cm x 45,6cm x 49,3cm)
• Weight: 64.4 lbs (29 kg)

Carrying Cases

Rather than in paper boxes, all speakers and subwoofers are delivered in rugged black nylon carrying cases with side pockets, thereby simplifying transportation for personal reference monitoring in commercial studios, and for on-location jobs.
