The SPX-65 is a full-range, self-powered sound reinforcement system with a tightly controlled vertical dispersion pattern, which improves the acoustic coupling at shorter distance. This feature enables several SPX-65’s to be flown or stacked to emulate a medium size curved line source. SPX-65 cabinets can be used in vertical configurations starting from one cabinet, up to six cabinets with the partly integrated rigging system.
The SPX-65 packs a carefully matched 12-inch mid/bass driver and two 1-inch HF drivers, each loaded on a Wave-shape-transformer™ entering the constant directivity horn with 65 degrees horizontal and 20 degrees vertical dispersion. The SPX-65 excels in smooth acoustic coupling, vocal transparency and SPL in small to medium sized configurations. Together with an accompanying sub low system, like an SP18 sub cabinet, the frequency response can be extended an octave downwards. For most programme material the power balance between one SPX-65 and one SP18 sub-low will be just right.
The SPX-65 is part of the SOUND PROJECTS Sigma Series (hybrid line-array line) and is the result of endeavours to create the ultimate modular sound reinforcement system. It encompasses a ribbon source line-array as well as more conventional point source systems.

Netherlands, SOUND PROJECTS introduces the new self-powered SPX-65 to augment the SPX-series of identical, yet acoustically complementary loudspeaker systems.
Within the SPX family each model is optimized for a specific coverage or function. In those situations where one point source cabinet will not deliver the necessary SPL or coverage, the SPX-65’s neatly fills the gap. Because of its constant horizontal coverage angle of 65 degrees and semi curved wide 15 degrees vertical radiation, it will deliver a flat slice of audio in the mid and higher frequencies. Wide enough to be used as a single infill en narrow enough to be used in multiples, a column or as a traditional sized line array module. The pragmatic fly frame and greatly simplified rigging hardware help the technician to quickly find the proper angles. For system designers and architects the SPX-series is a one stop shopping tool. Convenient for touring as well as fixed-installations. The plug and play - self powered design reduces or even omits complex external speaker management.
The visually identical appearance does justice to the growing consensus that loudspeakers should not distract audience attention but unobtrusively merge with the stage or listening environment. This holds for temporary, touring as well as fixed installations.
Additionally combinations with other SPX models can be made to create small or medium sized line of curved array columns. To create uniformity in sound, all SPX models share the same 12” long excursion driver to handle the low and mid band. The remaining and unavoidable differences between respective HF assemblies are virtually eliminated by SOUND PROJECTS proven proprietary speaker management and Micro Amps.
Musical stalwarts The Dubliners, who will celebrate their 50th Anniversary next year, are currently on the road across Europe with rental and production company Audio International, debuting Sound Projects’ SPX-65 loudspeakers.
“The Dubliners typically play in venues with capacities of between 1,200 to 3,000 people and I was looking for a system that was flexible enough to be used as ground stacks or be flown in a traditional line array,” comments Tom O’Brien, long-time chief FOH engineer with the band. “The Sound Projects SPX-65s afforded us the luxury of doing this with very little extra effort as the flying hardware can easily be adapted and used to ground stack the loudspeakers. The angling of the cabinets is simple and we are able to cover the smaller and medium auditoriums quite easily.”
The SPX-65 is a logical complement to the SPX range of speaker systems – the newest addition is designed to fill the gap where a one-point source cabinet is not delivering the required SPL or coverage. “Because of its constant horizontal coverage angle of 65º and semi-curved 15º vertical radiation, it will deliver a flat slice of audio in the mid and higher frequencies. It is wide enough to be used as a single infill yet narrow enough to be used in multiples, a column or as a traditional-sized line array module,” comments Margien Dikken, of Netherlands-based Sound Projects.
The SPX-65’s self-powered plug and play design avoids complex eternal speaker management – each unit houses one 12” mid/bass excursion driver and two 1” HF drivers, which are loaded on a double Wave-shape-transformer, terminated by a constant directivity horn with 65º horizontal and a 15º vertical dispersion.
O’Brien adds that he chose the SPX-65s primarily on their sonic quality. “The response is very smooth throughout the vocal range with excellent intelligibility and a high SPL. As Irish folk music tells stories through song and music it is important that the audience understands the text. We were impressed with the coverage of the SPX-65s and we also like the fact that they are self-powered, which means not having to hump around heavy amp racks. All in all the SPX-65 is a great speaker with a lot going for it. The Dubliners have been on the road for 49 years and they do not want to be worrying about the logistics and complexities of touring a sound system, so they trust me to look after their FOH sound and have done for 23 years, but they do want their music heard!”
