Morel SCM 634 Midrange

Morel SCM 634 Midrange

Supreme Coppersleeve 6" Midrange, 4Ω.

Morel Logo

The Morel SCM 634 Midrange drive unit combines many of the Morel proprietary technologies and innovations resulting in an exceptional drive unit: The Uniflow™ Aluminium diecast chassis gives maximum undisturbed airflow and minimal rear reflection; the Coppersleeve / Faraday pole piece negates rising voice coil impedance therefore maintaining linearity; the motor system is superbly engineered featuring a Hybrid™ Neodymium / Ferrite mixed magnet assembly and a large 3" voice coil wound with Hexatech™ Aluminum wire.

The SCM 634 features a sandwich cone composed of Carbon Fibre outer layers bonded to a Rohacell® structural foam core - a cutting edge technology more commonly found in the aerospace industry. The extremely rigid and light cone offers a highly dynamic sound with great pace and control.

The frequency response is tailored specifically for midrange reproduction and is very flat with superb linearity between 1-5 kHz; the useable response extends to 7 kHz. Power rating is 150w nominal and can withstand short term peaks of 1000 watts. A full datasheet can be downloaded from the bottom of this page.

Superb drive unit - highly recommended.
