We now hold good stock of the complete range of Intertechnik cascadable crossover network PCBs. This unique series of modular boards is available in 3 size ranges and 4 network derivatives that can be intermixed allowing ultimate design flexibility. They can be cascaded to suit your desired crossover alignment / drive unit complement. An example schematic is shown below:
In the main example above, the 2 way board is the motherboard; adding the low pass and high pass modular boards forms a comprehensive 3 way design with much scope for experimentation. This is just one illustration, these boards are highly adaptable and can be cascaded to suit literally any design.

These precison wound high - end inductors are available in a wide range of values of between 0.15mh - 15.0mH 1% tolerance and 3 wire gauges: 0.5mm x7, 0.6mm x7 and 0.8mm x7.
The thermally bonded Litz wire is configured as a concentric, hexagonally wound conductor consisting of 7 individually insulated high purity (99.99%) OFC strands. These air core inductors have low DCR resistance, high quality factor, very low skin effect, no saturation distortion, no hysteresis distortion, vibration / microphony immunity, very low self capacitance and a constant inductance characteristic regardless of current and load changes.
A perfect no compromise choice for the very highest fidelity loudspeakers.
Made in Germany by the long established and highly respected manufacturer Intertechnik / Audyn.
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.
We now supply Fountek Ribbon Tweeters, Full Range Drive units, Midrange Drive units, Midwoofers and Subwoofers.
The Fountek Electronic Company was established in 2003 and although in the loudspeaker world they are a relatively new company, they have established a reputation for top level R&D + manufacturing excellence. Their Ribbon tweeters such as the NeoCD3.0 are well known in the audiophile world and can be found in various high-end oem designs. Another stand out design is the large format 10" / 255mm ribbon tweeter NeoPro10i whose broad band response opens up 2 way design possibilities with 8 or 10 inch woofers.
Fountek specialise mainly in metal drive units, all but one of their range exclusively feature aluminium / alloy diaphragms and their expertise with the subject matter can be seen in the many good performing drive units they produce; a couple of examples being the full range FR135EX and the FW146 midwoofer, both excellent sounding, good value drive units.
We now stock genuine foam surrounds for the highly popular Scanspeak 18W Classic Series Midwoofers, thus enabling cost effective repair of various historic Proac loudspeakers that were fitted with oem versions of the 18W/8542 (and its polypropylene coned derivatives) without the expense of changing complete drive units.
Some of the models covered:
Super Tower 0, MkII
These spare parts are direct from the Scanspeak factory, for more info click on the image below or click HERE.

Following many customer requests we now have 50 watt 16 Ohm L-Pad attenuators ready for immediate dispatch from the UK. These elusive spare parts are perfect for restoring vintage loudspeaker models with L-Pads such as the classic AR 4x and many other 15-16 ohm models from the valve era; also suitable for vintage guitar amps featuring EL84 single ended or push - pull output stages with a fixed 16 ohm output tap.
Rather than using specific crossover capacitors, the 753 featured standard aluminium electrolytics wired in series to form non-polarised electrolytics- this far from ideal cost / space saving excercise was part of the price to performance balance, and to be fair worked reasonably well but is now a prime candidate for upgrade. Click on the picture for more details:
Another potential problem with the 753 is the very high tweeter failure rate and subsequent crossover damage:
The 753 often turns up on auction sites with dead tweeters - running these speakers with open circuit tweeters for extended periods of time causes the tweeter bypass inductors to heat up and melt; we supply a kit of components to cure this issue:
We now offer a rebuild / refurbishment service for selected Bowers and Wilkins tweeters. Current supported models are P4, P5, P6 and CDM1 - we will expand this list in line with demand. Please click the image above for full details or click here: B&W refurb.
This new service compliments our range of genuine spare parts for other manufacturers:
