Morel Classic Advanced CAW 428 4.5" Woofer

The Classic Advanced CAW 428D 4" Woofer from Morel represents a refined approach to mid-bass reproduction, engineered to deliver controlled low-end extension with exceptional clarity. This compact driver is ideally suited for audiophiles seeking to upgrade factory sound systems or build custom enclosures where space is at a premium, offering a seamless blend of punch and precision that elevates both music and home theatre applications.

At the heart of the CAW 428D lies a damped polymer composite cone, meticulously formulated to suppress unwanted resonances and ensure accurate transient response. The Hexatech™ aluminium voice coil further enhances performance by providing superior thermal management and low moving mass, resulting in an impressive sensitivity of 88 dB and a total Q factor of 0.33 for tight, well-defined bass. With a maximum linear excursion of 4 mm and a DC resistance of 5.5 ohms, this woofer handles dynamic passages with ease while maintaining low distortion. The 101.6 mm nominal diameter and four mounting holes facilitate straightforward installation, making it a versatile choice for sealed or ported designs. Whether used as a dedicated mid-bass driver or part of a multi-way system, the CAW 428D delivers the authentic, articulate low-end that discerning listeners demand.
