These SP2-10s debuted at the Classic Rock Festival 2008 in Sandnes where the acts included Def Leppard, Led Zeppelin, Slade and Thin Lizzie. The sound system featured Sound Projects SP2-10s, Sound Projects Linex and 36 SP18 extra subs.
The self-powered SP2-10 complements the SP18 frontloaded vented sub-bass. With these identical shaped cabinets a wide variety of low-end configurations can be composed to augment the low end of any sound system, says the company. Physically the SP2-10 matches the Sound Projects Linex line array system.
Like the SP18, it's twin brother system, the SP2-10 is equipped with the same simple and elegant rigging or locking system. This means that, besides sound colour and headroom, the system engineer can also manipulate the radiation pattern. Both vertical beaming as well as different cardioide radiation patterns can readily be accomplished by any combination of stacking and/or rigging, augmented by digital beam steering if deemed necessary, says the company.
The SP2-10 is optimised to cover the most dynamic and the most powerful frequencies of music (60 - 160 Hz). Horn loading improves low frequency directivity and, because the horn also acts as an impedance-matching device, maximizes driver efficiency. The SP 2-10 offers more than double the efficiency over direct radiators and has the great musical benefits of fast transient performance. Because less amplifier power is required to achieve the same SPL relative to a large 15" or 18" direct radiating driver, driver excursion and, therefore, distortion are reduced.
