More Scanspeak Ellipticor units.

Scanspeak logo

We have added 3 more products to the flagship Ellipticor range:

18WE/8542T00  8 ohm 6½ inch Midwoofer

21WE/4542T00  4 ohm 8 inch Midwoofer

21WE/8542T00  8 ohm 8 inch Midwoofer

Scanspeak Ellipticor info:

Traditional (round) drive units are relatively easy to produce but come with many inherent issues such as ringing (bell modes), break up, high Q peaks and poor edge termination. To counter these problems Scanspeak started the Ellipse project under the guidance of the late great designer Birger Jørgensen, sadly Birger passed away before seeing the completed drive units. The Ellipse project was completed and brought to production by Dennis Hansen and Simon Møller Nielsen under the trade name 'Ellipticor'.

The design aim of the elliptical motor system is to break any symmetry within the voice coil former and provide the cone with a non symmetrical driving force so that bell modes and other distortions cannot propagate. Machining and building the elliptical parts for the motor system provided many R&D and engineering challenges that Scanspeak have overcome with custom built tooling and new assembly techniques.

The Ellipticor drive units are ground breaking products that are extremely well behaved, broad banded and truly represent the state of the art. You can read custom loudspeaker design supremo Troels Gravesens comments on the Ellipticor units here.

New products: Heil Air Motion Transformer Tweeters.


Air motion transformers (AMT) are a unique type of high-end ribbon tweeter which were developed by German physicist Oskar Heil during his research into the characteristics of the human ear.

Although AMTs are members of the ribbon family, they have a radically different mode of operation: these tweeters feature a specially pleated Kapton / aluminium diaphragm that has no forward / aft motion, instead it expands and contracts along its length like a bellows, transforming an electrical signal into air waves and can therefore technically be viewed as a type of sound modulated air pump. The folding of the AMT diaphragm offers a surprisingly large radiating area in the minimum of space; a 25mm wide AMT diaphragm has a similar active radiating area to an 8 inch drive unit.

AMT tweeters have a highly dynamic sound with an excellent transient response, very high efficiency and low harmonic distortion.

  • EU PSD2 14/9/19 compliant (**what's this ??**)

A set of extra features are in development and will be integrated later this year.

What is EU PSD2 Directive ?


The revised Payments Services Directive (PSD2) regulates the payments industry in the European Union. One of the major updates that comes into effect this year is stronger protection for customers who shop online using their debit and credit cards.

To comply with these new regulations, online sellers need to make sure they have Strong Customer Authentication (SCA) for payments they accept from European buyers to help mitigate card-not-present fraud.

Strong Customer Authentication is similar to what many people refer to as two-factor authentication: if a customer is buying online using their debit or credit card, SCA may require them to use two forms of authentication. As an example, instead of just entering their PIN or password, Strong Customer Authentication would prompt a customer to enter a code generated on their banking app as a second step. This makes it harder for fraudulent transactions to get through.

Customers are asked to enter this information only when it’s required through a technology known as 3D Secure—an extra layer of security that customers have to enter during checkout to authenticate themselves. Our customers will see the 3D Secure indicator start to show up on orders after PSD2 comes into effect.

Whilst PSD2 may initially seem like another layer of bureaucracy, it is in fact a major security upgrade that will protect both buyers and sellers from scammers using stolen cards.

The technology is already in place and we are already compliant with the upcoming EU PSD2.
