Frequently asked questions
Can I use the 3733-M/HF without a separate bass cabinet?
No. The 3733-M/HF is a mid-high section only and requires the separate JBL 4739 low-frequency cabinet to form a complete three-way cinema system. It cannot function as a standalone full-range speaker.
Which speaker is better for live touring and events?
The CWT128 is designed for live performance with wide 160° coverage, high SPL output (129 dB), compact weight (40.9 lbs), and multiple mounting options. The 3733-M/HF is fixed-installation cinema-only and not suited for touring.
What is the frequency response difference between these two?
The 3733-M/HF paired with the 4739 LF delivers 40 Hz to 19 kHz full-range. The CWT128 spans 96 Hz to 19 kHz (±3 dB), extending to 71 Hz at –10 dB, making the complete 3733 system reach deeper low frequencies but requiring separate amplification and integration.
Can the CWT128 work in 70V distributed systems?
Yes. The CWT128 includes an integrated 70/100V transformer with multiple power taps (110W, 55W, 28W) and an 8-ohm bypass for direct amplification, enabling flexible commercial and hospitality installations. The 3733-M/HF requires custom bi-amp crossover integration.
