MS218. compact, self-powered, dual-18.

MS218 delivers classic dual-18 punch within ultra-compact dimensions, and at a very comfortable weight. This extreme level of performance is made possible by the ulta-fast, ultra-precision, Neodymium powered 18 inch drivers: even in an enclosure with such compact dimensions, the class-leading B/L factor delivers full excursion with full control. Utilising the renowned Chameleon ultra-linear circuit achitecture, the in-built power amplifier guarantees full performance, total precision and instant response: all the time.


Signal input

Each unit accepts a +4 dBu balanced input via 3 pin XLR male and female connectors, and collects power via Neutrik PowerCON connector. The product features a simple yet easy to read signal / peak light system on the rear.


The MS218 has been equipped with the same OverBlast™ technology as other Hill amplified products. This enables the fan circuit to follow the audio input and act accordingly. Loud music allows the fan to blast, but silence causes the fan system to slow down.



The classic Hill taper-reflex design, features premium grade 18" drivers with an immense 64mm linear excursion capacity, housed in an enclosure constructed from 13 ply Baltic birch. This combines with the ultra-linear Chameleon™ amplifier to deliver precise, tight, wide-band LF performance. The result is true recreation of the punch from a kick drum, the heavy flow of a bass guitar and the depth of a keyboard with equal assurance.

Absolute Precision

The MS218 delivers exceptional low frequency pattern control and can be configured in multiple array formats to minimize back-stage and off-site spill. With no internal destructive limiting DSP, the MS218 delivers full impact, all the time.


Pure Style

Among its class, the MS218 form factor is small but extremely impressive. Being only 49.8cm / 19.6" tall enables it to sit perfectly understage, or double stacked for even more power. Couple this with considerately designed handles and castors and you have the ideal touring sub.
