The black QSC E118SW Passive Subwoofer is a high-performance direct radiation subwoofer, well suited for sound reinforcement applications including live performance, DJ and dance music, karaoke, and event production. The E118SW requires an amplifier with a minimum of 800W continuous (3200W peak) to power the 18" woofer, which offers a frequency response of 37 to 230 Hz (-6 dB) with a peak SPL 133 dB.

QSC recommends the use of a speaker processor or a power amplifier with integrated DSP in order to set crossovers, limiting, and equalization to ensure the best performance. QSC's GXD or PLD amplifiers, as well as TouchMix digital mixers offer on-board DSP and factory-tuned presets, which provide settings for live sound reinforcement, stage monitoring, dance music, and karaoke.

The rugged plywood enclosure is coated in black textured paint and features a heavy-duty grille lined with foam for protection. A threaded, M20 pole socket and speaker pole are provided for sub/satellite use with any of the E-Series two-way full-range loudspeakers. For portable applications, the E118SW includes attachment points for four optional casters.

Q: 6. What's the difference between this DRM 18S cab and the SRM 1850 cab? Why is there no specific sub for the SRM215-V-Flex cabs? I want to get the latter but your Mackie sub lines are confusing.

A: There are several differences between the two models and the best option would be based on your system and the type of application you would be using the subwoofer for. The DRM18S-P is a passive subwoofer capable of handling 500W RMS and 2000W peak power from a separate power amp. The SRM1850 is an active subwoofer which has a built-in power amp capable of producing 800W RMS and 1600W peak. The frequency response range and threshold for SPL are the same for both models. The DRM18S-P can be mounted on a pole or suspended while the SRM1850 is designed to be placed on the floor or stage and should not be pole mounted or suspended. I hope this information is helpful.
