SP-21E

The SP21E is a compact self-powered high SPL sublow system.

The cabinet is constructed of rigid, multilayer-birch ply reinforced with

multiple bracing and finished with a sturdy coating.

Cabinet dimensions are optimised for international trucksize.

Ergonomical grippoint layout, nano Armor polyurethane coating and

additional corner protection with multiple slide bars facilitate easy transport. Protective slidebars facilitate locked stacking of more  cabinets.

Polemounting can be done standing or flat. The SP21E will endow any F.O.H

system with a rock solid foundation in the lowest audioable 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.

To match the desired cabinet and to obtaion maximum effciency, state-of-the-art computer aided modeling techniques and acoustic calculation programs are used to precisely indicate the mainfold reinforcing ribs and port tuning.
