QS 150i Two-way Passive Speaker If there is one rule for modern audio, it's "all small box systems will be pushed too hard!" If it has to be small and it's going to be driven hard, it's time for a QS 150i. This very compact multi-purpose live sound/installation speaker system is loaded with custom-designed Quest manufactured components including the new Quest HF rotatable wave-guide. Designed to be versatile, it is ideal for live micro PA, music installations and where ever you need small full range speakers to produce extra dB without the extra price.
