Sound Projects SP15E_PERSPECTIVE.png

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 featherwieght of 50kg solid sub due to an inventive cabinet construciton loading a light, 4 inch coil, neodymium driver and ultralight 1500 Watts CCD amp.

Cabinet demensions are optimised for international tucksize.

Ergonomical grippoint layout, nano armor polyurethane coating and addtioanl corner protection with multiple slide bars facilitate easy transport. Protetive sildebars facilitate locked stacking of more cabinets. polemounting can be done standing or flat. The SP18E will endow any of F.O.H system with a rock solid foundation in the lowest audible octaves.

The S.A.L.C(Single Audio-Logic level control) speaker management is proprietray RMS based gain riding circuit which maintains the tonal balance of the sound as preceived bt the human ear and protects the drivers from over excursion or overheating. A recessed switch facilitates Sound Projects standard* or free external lowpass selection.
