Frequently asked questions
Can I use the AC115S on stage for live rock or hip-hop?
The AC115S is technically capable but is designed primarily as a subwoofer foundation rather than a full-range stage cab. You would need additional mid and high-frequency cabinets. The SRX815 is purpose-built as a complete two-way solution for those genres.
Which is better for a mobile DJ setup?
The AC115S excels when paired with satellite speakers for deep electronic bass control. The SRX815 offers more versatility as a standalone full-range cab if you want compact transport and don't need extreme sub-bass extension.
How do the frequency responses compare?
The SRX815 specifies 41 Hz–20 kHz full-range response, making it a complete speaker. The AC115S is a subwoofer optimized for the lowest frequencies; its exact low-end spec is not provided, but subwoofers typically operate below 200 Hz and pair with separate midrange/tweeter systems.
Which system is easier to integrate into an existing rig?
The SRX815's passive, two-way design works as a standalone unit or within larger PA systems with straightforward power requirements. The AC115S, as a subwoofer, requires integration with other frequency components, giving the SRX815 an edge for simple, all-in-one deployment.
