Frequently asked questions
Can these products work together?
No. The 3733-M/HF is a mid-high cinema component that requires a separate 4739 low-frequency cabinet and external amplification to function as part of a complete three-way theater system. The SRX918SF is a standalone powered subwoofer designed for live sound reinforcement venues and touring applications, operating independently with its own 2,500-watt amplifier.
What frequency ranges does each cover?
The 3733-M/HF covers mid and high frequencies only; when paired with the 4739 LF cabinet, the complete 3733 system spans 40 Hz to 19 kHz. The SRX918SF focuses on low frequencies with a linear response down to 35 Hz, designed to complement main loudspeaker arrays in live sound systems.
Which is better for my venue?
If your venue has a fixed screen (cinema, theater, or permanent installation), the 3733-M/HF is purpose-built for that application. If you need mobile low-end reinforcement, touring capability, or festival deployment, the SRX918SF's powered design, rigging options, and networked control make it the professional choice.
What are the power requirements?
The 3733-M/HF requires external amplification rated for 300 W input and demands a separate bi-amplified system including the 4739 bass cabinet. The SRX918SF is entirely self-contained with a 2,500-watt integrated amplifier requiring only AC mains power and audio input.
