A small sub with a monster footprint. Fly it, hide it, hang it, as an ultra-compact passive sub bass for mobile audio or permanent installation, the HPI12S is a spectacular performer. Light in weight and high in LF output, the HPI12S is ideally suited to small medium sized venues that require authentic sub bass with a very low visual profile.

A Closer Look

The custom built 12" driver in the HPI12S is one of the very few loudspeakers with cone material made from Australian eucalyptus hardwood. This material has strength like a composite material but the warm sound of a cardboard cone; much loved by hi-fi enthusiasts. The benefit with the Quest driver is it can take serious punishment while still sounding like high end studio.

A (small) Pro Package

Internal rigging points allow the sub bass to be flown for permanent ceiling installation with four top mounter reinforced inserts and one extra on each side. A 35mm top hat can accommodate a standard speaker pole for mounting a satellite mid-high box. Power handling is high for such a small system with a power amplifier recommendation of 600W nominal.

Compact & Clean

The birch ply casing looks serious and is built to last the distance in a high performance environment. The angled connector panel is a thoughtful addition to act as a strain relief to the speaker connection and also make it possible to mount the box next to a wall if necessary.

Power Me Up

The HPI12S is a serious compact sub. Quest Engineering recommends an amplifier capable of delivering 500-600W (nominal) to ensure full performance. The perfect solution are Quest's QM1000P, QA2004 or the new QX4500
