Morel BMW Integration Reference IR-BMW42-CTR 2-way plug-and-play centre speaker

The IR-BMW42-CTR uses a unique chassis design with snap-in tweeters and factory wire connections for straightforward installation in modern BMW models. No modification is required. Based on Morel's Hybrid speaker series, it delivers high power handling and tight cone control at Reference level.

The 4-inch (100mm) woofer uses a 2.1" (54mm) voice coil with Morel's hybrid EVC™ motor design. The tweeter uses a proprietary 28mm Acuflex™ silk dome with a dual neodymium magnet motor. The result is a high-performance plug-and-play speaker designed specifically for BMW centre channel positions.

DPC Cone

DPC (Damped Polymer Cone) is derived from the cones Morel has built its reputation on. High self-damping characteristics deliver sound quality without colouration or harshness.

EVC Motor

EVC™ technology uses large voice coils for improved heat dissipation, power handling, and linearity. The motor system sits within the voice coil, directing all magnetic energy there and eliminating stray magnetic flux. The result is a compact, magnetically shielded, efficient design.

Handcrafted Acuflex Soft Dome

A specially engineered damping compound is hand-applied to the soft dome, adding rigidity and damping to improve clarity and bandwidth. The Acuflex™ diaphragm uses controlled cancelling break-up (accurate–flexing), where each break-up mode is counteracted by another in the opposite direction, producing a smooth frequency response.

Hybrid Magnet Motor

The Hybrid motor combines a ferrite magnet with a powerful neodymium magnet to create a compact, lightweight, and powerful motor system. More amplified power is converted into sonic energy, delivering strong performance even from a small driver.
