The SP15E is a compact self-powered high SPL subbass system. The cabinet is constructed of a rigid, multilayer birch ply reinforced with multiple bracing and finished with a sturdy coating. An impressive featherweight of 50 kg solid sub due to an inventive cabinet construction loading a light, 4 inch coil, neodymium driver and ultralight 2500 Watt CCD amp.

Cabinet dimensions are optimised for international trucksize. Eight barhandles placed in an ergonomical grippoint layout, Nano Armor polyurethane coating and additional corner protection with muliple slide bars facilitate easy transport. Locked, stable stacking of several cabinets is easy because of the protective slidebars. Polemounting can be done both standing or flat depending on available floorspace. The SP15E will endow any F.O.H. system with a rock solid foundation in the lowest audible octaves.

A recessed switch facilitates Sound Projects’ standard* or free external lowpass selection. The SALC (Single Audio-logic Level Control) speaker management maintains the tonal balance of the sound as perceived by the human ear and protects the drivers from over excursion or overheating. Maximum sub efficiency for the desired cabinet dimensions is obtained by creativity as well as state-of-the-art computer aided modelling techniques and acoustic calculation programs.
