Frequently asked questions
Can I use the 3739 as a standalone subwoofer?
No. The 3739 is a bass-only cabinet component with no mid or high-frequency drivers. It requires a matching JBL ScreenArray mid/high top section (sold separately) to produce full-range audio. The AWC15LF, by contrast, is a complete subwoofer ready to use independently.
Which one is suitable for outdoor use?
Only the AWC15LF is designed for outdoor environments. It carries an IP-56 weather rating, corrosion-resistant construction, and outdoor-rated terminals. The 3739 is an indoor cinema/theater component with no weather protection.
How much amplifier power do I need for each?
The AWC15LF includes a 300W transformer and handles 500W continuous internally. The 3739 requires a 600W amplifier and presents a 4 ohm impedance, so you must source and purchase a separate amplifier for it.
Which delivers louder bass output?
The 3739 is more efficient, with 104 dB sensitivity compared to the AWC15LF's 94 dB, meaning it produces louder bass from the same amplifier input. However, the AWC15LF delivers sufficient output for outdoor events and is optimized for weather resistance rather than maximum cinema-style power density.
