The first speaker to utilise the Hybridtec system is the all-new QM 450A compact powered speaker system designed and built in Melbourne, Australia. The QM450A delivers a full 450W RMS output and uses the same birch plywood timber chassis as the extremely popular QM350i. With a chassis designed to deliver optimal linearity in its passive form, it proved the logical foundation for an active system.
 
Revealing Details
Lightweight, reliable, powerful and sonically impressive… This is the discerning criteria demanded by every professional for a powered speaker system. While every manufacturer has these goals in mind, achieving these deliverables can prove a difficult task, especially when a realistic price point is also a driving factor.
 
Hybridtec Amplification
Quest has broken the moulds of orthodox design yet again with a revolutionary concept in professional audio amplifier design. Quest Hybridtec is an Australian developed digitalanalogue hybrid amplifier module which utilises the best of both worlds.
 
The design philosophy behind Hybridtec was simple: “use each type of technology according to its strengths as opposed to trying to make less appropriate technology suit just to meet a budget”.
 
The result, an amplifier with a digital low end component and an analogue high frequency section.
 
Accuracy & Control
The QM450A features a purpose designed high frequency driver coupled to Quest’s custom designed asymmetrical wave-guide. The wave-guide can be rotated through four dispersion plains maximizing the QM450A’s application potential further.
 
The 12” horn sports a wide 90-100 degree coverage at the base of the flare and a long throw 40 degrees at the top. This feature means that the HF energy can be directed accurately wherever it is needed without adding unnecessary reverberation.
 
 
This unique horn geometry design minimizes “hot zones” making instances where microphones are positioned closely to speaker systems a non-issue for monitor and FOH engineers.
 
Wooden Body, Steel Faced
The QM450A chassis is made of the same heavy duty birch ply wood as our high performance and industry trusted HPI systems. Finished with an extremely resilient black coating and fitted with a wrap-around heavy gauge protective steel grille, the QM450A has been crafted to endure even the most demanding environments and is built to last.
