Morel TSCM 634 Midrange
The Morel TSCM 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, a Titanium voice coil bobbin and a large 3" voice coil wound with Hexatech™ Aluminum wire.
The TSCM 634 features a composite 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. 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.
