Frequently asked questions
Which one should I pick for live sound reinforcement?
The SRX835 works well as a standalone main or fill speaker because it's a complete three-way system with 137 dB peak SPL and integrated crossovers. The AC118S is best paired with mid and high-frequency speakers to form a larger rig, since it's a subwoofer alone.
What's the key difference in how deep they go?
Both reach 32 Hz, but the AC118S uses an 18-inch woofer optimized specifically for sub-bass articulation and extension, while the SRX835's 15-inch woofer handles bass as part of a broader three-way design. The AC118S will feel heavier and more authoritative in the lowest octaves.
Which is easier to transport and set up?
The SRX835 is purpose-built for touring with ergonomic handles and twelve suspension points for flying or stacking. The AC118S at 32.3 kg is portable for a subwoofer, but you'll need separate mid and treble speakers to complete a system.
Can either one work as a standalone speaker for a DJ or small venue?
The SRX835 works as a standalone main speaker with its full three-way design, 137 dB SPL, and flexible mounting. The AC118S requires pairing with additional speakers and is not intended for full-range operation by itself.
