The ESX Audio Quantum QXE series stand-alone kits are at a level of material and finish that is usually seen on much more expensive speakers. Cones made with a combination of polypropylene and fiberglass are rigid but in addition to excellent performance, the sensitivity has been considered good. The elements can withstand even higher powers and cracks remain low, thanks to 30mm voice coils and strong magnets. The bass reproduction in the QXE series is clean and very dynamic.
The 25mm textile dome tweeters have clear but unstressed sound. Of course, good installation accessories for various surface and flush mounting sites are included. Installation friendliness has been taken to a new level by splitting the crossover filter in half, both the treble and bass filters are separate so the car’s original wiring can be fully utilized. This simplifies installation, especially when the treble is in the a-pillar or dashboard instead of the door.
