Overview 

The triple 15″ Yorkville Sound SA315S is a professional, powered portable PA subwoofer from the Synergy Array Series system designed to be used as a dedicated subwoofer for the SA153 full-range top or used in conjunction with the SA153 and the SA221S powered subwoofer to create a scalable point-source sound system well suited for professional sound reinforcement companies, rental houses, touring bands, musicians, festivals, concerts, mobile DJs, and other sound providers.

Yorkville has invested a lot of time and research into developing and building their own amplifiers, customizing other raw speaker manufacture products and using sophisticated DSP to optimize performance/protection, resulting in remarkable peak power performance. The S315S provides a punchy transient, followed by an enveloping sustained bass tone, making it a great addition to any setup.

The rear panel provides a simplified set of controls for integrating the subwoofer into any environment. There are indicator LEDs for power, activity, input clip, X-Max limiting, and VC-Limiting. The integrated DSP provides processing to prevent over-excursion (X-Max), voice coil overheating (VC thermal) and clipping. With the use of IIR filters for crossover and equalization, the Synergy system provides clean and accurate audio reproduction.

A small delay is added to time align with the SA153 top box, while the X-Max limiter and the VC thermal limiter are both frequency sensitive and calibrated to match the characteristics of the driver and cabinet system. The Sub Level control knob attenuates or boosts the subwoofer’s output, while a dedicated Average Power Limit knob (100%, 75%, and 50%) can be advanced to limit the power draw in cases where there is less than ample power available. This is a huge benefit for touring and mobile applications, where the available power changes from night to night. By limiting the average power, you can ensure that you won’t trip that 15-amp breaker that happens to be sharing power with the ice machine.

The SA315S has a single XLR input with two parallel XLR outputs for connecting a SA153 speaker or additional SA315S or SA221S subwoofers. Up to 20 subwoofers/tops can be daisy-chained without signal loss (with balanced cables). The rugged enclosure is made from 15mm Birch plywood with a tough speaker paint coating. The subwoofer features a rail and lockbar rigging system makes flying the system a safe and simple affair. The lockbar also attaches to the cabinet dolly for safe and easy transport. Interlocking UHMW feet and cups are also on the top and bottom to ensure stability when stacking.  A power cable is included.
