Product review : Morel TSCW 636 Woofer

The perfect cone conundrum..

Morel logo

For decades loudspeaker designers and manufacturers have pursued the ultimate goal of the perfect cone composition. From paper / pulp to raw and loaded plastics such as bextrene, cobex and polypropylene, metal cones, glass fibre cones and sandwich cones - all looking for the elusive optimal mass vs. internal damping vs. linear output ratio. Of course perfection can never really be achieved as perceived sound quality is subjective and every aspect of a loudspeaker system is in some way a compromise.

There are some drive units that incorporate very innovative technologies and high-tech cone materials - one such unit is the Morel TSCW 636:

Morel TSCW 636

Morel drive unit coding:

TSCW = Titanium Supreme Coppersleeve Woofer.

So, this drive unit features a titanium voice coil former, is from the Supreme range and has a coppersleeved pole piece (essentially a Faraday ring).

636 = 6 inch chassis, 3 inch diameter voicecoil, 6 ohms impedance.

Morel use this coding system across their entire range of drive units.

TSCW 636 key features:

Many manufacturers now offer maximum airflow chassis - the Morel version is called the Uniflow™ chassis, it is diecast aluminium and gives maximum undisturbed airflow with minimal rear reflection; the heavily vented pole piece is sleeved with copper thus forming a Faraday ring to negate 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 - this winding technique removes the air gaps found when using round section wire and first featured on the legendary and still sought after MDT-33 from the early 1980s.

The TSCW 636 cone features a composite sandwich of woven carbon fibre outer layers bonded to a Rohacell® structural foam core - an ultra lightweight cutting edge technology more commonly found in the aerospace industry, notably the Airbus A380. This extremely rigid and light cone material offers excellent internal damping and a highly dynamic sound with great pace and control.

The frequency response is very broad with excellent bass weight and extends upwards to 7Khz with an almost pencil flat midband between 2-4 kHz. Power rating is 150w nominal and can withstand short term peaks of 1000 watts.

The first cone breakup peak occurs at around 6.5 Khz and is easily notched with an LCR network - if coupled to a 4th order LR alignment, a minimal phase 2 way system with a crossover point usefully away from the critical 2-4 Khz band is possible. Combine this drive unit with a high end tweeter such as the benchmark Hiquphon OW1 or Scanspeak D3004/660000 for an ultra high end home design.

An excellent exotic drive unit capable of top notch results.

Also available as a dedicated midrange unit: Morel TSCM 634 Midrange
