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:
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.
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

We've been having a good sort out in the warehouse recently to make room for a large quantity of incoming products - truth be told, we've been putting this job off for a while as it's a major task, however every cloud has a silver lining: we've found various treasures tucked away and will be adding them to this website over the coming weeks.

These tweeter kits significantly upgrade the far eastern sourced Linn tweeters type 015/1, 015/3, 015/5 and 038/2 (very early 'mesh' type and all 3 bar ceramic versions). Our Hiquphon upgrade tweeters are fastidiously hand produced in Denmark exclusively for us by tweeter supremo and former long time Scanspeak technical manager Oskar Wrønding.
Oskar's tweeters are designed and built to the highest exacting standards and take the performance of the popular Linn Keilidh to new levels of detail and transparency. Simple direct fit - no cabinet modifications required.
Each pair of tweeters are matched to 0.5db and supplied with individual response graphs.

TWARON® is a p-phenylene terephthalamide (PpPTA) Aramid synthetic fibre (phew..), a close relative of Kevlar and as such has unique properties that can be utilised for very effective sound absorption within speaker cabinets. The mechanism for attenuation is Twarons ability to efficiently convert vibration into low level heat. This innovative product is very different to standard wadding.
Twaron Angel hair is easy to work with and non-aging. It has a very high expansion ratio and will always try to fill the available space - all that is required is 3-5 grams of Twaron per litre of internal cabinet volume, making it very economical and far less likely to overdamp the midrange which can happen with traditional waddings such as wool, polyester or bonded acetate fibre (BAF).
Produced by Thüringische Institut für Textil- und Kunststoff-Forschung (TITK), exclusively for MUNDORF, Germany.

17v3.4.4
High grade MKP crossover capacitors from the worlds leading capacitor supplier.
3% tolerance 0.33uf - 47uf.
Featuring the proprietary Mundorf high precision EVOLUTION winding technology, these capacitors have an unusually narrow ultra high purity base foil that is metallised to the highest possible molecular thickness before being parallel wound in disc form - this process results in a very large active surface area with ultra low microphony; the cores are then potted into special non-resonant housings.
These hand spooled capacitors offer an extremely low ESR (equivalent series resistance). Asymmetric leads (larger values) allow for x or y mounting.
Highly dynamic sound with great transparency.
All values available from 0.1uf - 47uf, 450V (smaller values rated at 650V).
