Use our wiring wizard for simple wiring of speakers and subwoofers! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The data sheet shows you which connection the respective amplifier is designed for!
Our port calculator shows you which tuning your enclosure has! The net volume is always particularly important here; calculate the pure chamber of the subwoofer beforehand to arrive at the correct result. The net volume is calculated minus all displacements and is important when designing the enclosure.
The ESX Quantum QDK2 is a high-quality, complete sound deadening kit designed to optimize the acoustics of two car doors. The combination of aluminum butyl and two different types of acoustic foam effectively reduces annoying vibrations, resonances, and rattling noises.
The self-adhesive aluminum-butyl mats stabilize vibrating body panels and reduce unwanted resonance. In addition, smooth and dimpled acoustic foams are used to provide acoustic decoupling and reduce disruptive noise.
The QDK2 is particularly well-suited for retrofitting high-quality car audio speaker systems. The improved door insulation creates better conditions for precise bass reproduction and a clean sound. All materials are self-adhesive and can be cut to size.
