Frequently asked questions
Are the drivers and power ratings identical between these two?
Yes. Both feature dual 2279F 18-inch drivers with 3-inch voice coils, 2000W peak power, 1500W continuous output, and 141dB maximum SPL. The sonic performance and power handling are identical.
What is B-stock, and does it affect sound quality?
B-stock means the unit is open-box, display, or refurbished—not new. Sound quality is unaffected; the difference is cosmetic condition, warranty coverage, and potentially the absence of original packaging. B-stock units are fully tested and functional.
What advantage does HiQnet Ethercon networking provide?
HiQnet allows remote DSP control, EQ adjustment, and monitoring of multiple SRX828SP units across a network using Audio Architect software or iOS/Android apps. Product B uses standard XLR, requiring manual control at each unit. Networked control is essential for large touring rigs with multiple subwoofers.
Which is better for a small touring company or rental inventory?
Product A is preferred for rental or multi-unit touring operations because HiQnet networking simplifies rapid reconfiguration across different venues and allows one technician to control multiple subs remotely. Product B suits smaller tours or single-unit applications where this capability is unnecessary.
