Mundorf TWARON® Angel Hair Wadding.

Mundorf logo

What on earth is Twaron ?

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.

Mundorf MCap Evo Polypropylene Capacitors.

Mundorf logo

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.

In stock for immediate dispatch:

All values available from  0.1uf - 47uf, 450V (smaller values rated at 650V).

Scanspeak Ellipticor Drive Units

Ellipticor logo

 NEW PRODUCTS.

Scanspeak have released 2 new drive units - these state of the art units feature elliptical voice coils with copper clad pole pieces and airflow optimised magnet systems. The original concept was the brain child of the late great Birger Jorgensen, the project design being finalised and brought to production by respected designers Dennis Hansen and Simon Møller Nielsen.

The elliptical motor assemblies break traditional drive symmetry: the electro-magnetic driving force from the voice coil is not equidistant to the cone / dome surround therefore the usual breakup and high order bell modes do not propagate - mistermination and antiphase issues at the diaphragm / surround junction are also absent. Both drive units are very wide banded with no breakup modes that require any damping. Distortion figures are incredibly low whilst sensitivity is high. These drive units have discrete mountings - various colour trim rings are available.

The Ellipticor range are no compromise designs that set a new bar for high end drive units.

New old stock drive units from Audax.

 Audax logo

Audax were true innovators and released many cutting edge technologies never seen before such as the HDA (High Definition Aerogel) cone - a unique product based on acrylic polymer gel containing carbon and kevlar fibres in perfect molecular alignment. HDA was the product of extensive research for the perfect cone material that is both lightweight, rigid and displays high internal damping. Another breakthrough technology was the brilliant but sadly short lived 'gold eye' HD-3P: the  Audax HD-3P  tweeter was a piece of exotic, visionary engineering from the 1990s. Fundamentally a piezo tweeter, it featured a gold spattered elliptical diaphragm formed onto a nitrogen filled balloon. Technically and sonically brilliant but fatally flawed due to gas loss and barometric pressure changes; many are now defunct with low / no output or exhibit the 'crinkle of doom'. We supply a replacement kit for the HD-3P here:  Audax HD-3P replacement kit.

Here are some drive units for HFW Design range and others - click the links:

HFW KLS4     HFW KLS7

HFW KLS5     HFW KLS9

Heybrook Octet - HM170C4

Most of the Audax units that we stock are in their original boxes - some are incredibly rare and are probably the only ones available anywhere.
