FinkTeam’s Borg is two-way floor standing design featuring a 10.25 inch high-power mid/bass driver and an Air Motion Transformer (AMT) tweeter.

Borg is a significant design exercise as knitting a 10.25 inch mid/bass, albeit an extremely fine one, with a HF unit is never easy. To combine the two drivers to achieve a flat frequency response and, more importantly, a slow even mid/HF roll off in the power response is a significant feat of engineering. There is no off-axis hole in the middle effect.

Borg is designed as a more domestic friendly loudspeaker than the WM-4. Borg’s low frequency tuning is designed to deliver weight and drama to music but without making it a total diva when it comes to room positioning.

Of course, it isn’t as good overall as the WM-4 but then neither does it demand a huge room and the finest amplifier and sources. Believe us when we say that Borg will rise to the challenge of the finest electronics, but they are not essential to enjoy Borg’s talents.

The rear of the cabinets are real wood veneer, except the white black colours. Borg fronts are finished in Nextel.

Cabinet

Typical loudspeaker cabinets have pronounced structural resonances which are very audible and reduce the speaker’s ‘signal-to-noise ratio’. At FinkTeam, we take this aspect of loudspeaker performance very seriously because we know that a quiet cabinet allows the reproduction of low-level detail in a recording that is otherwise swamped by spurious cabinet output. Listener fatigue is avoided by reducing colouration and time smear. Stereo image focus is improved.

Fink Borg cabinetThe design emphasis is on panel damping. It is impossible to force all the panel bending resonances above the passband, so instead, they are damped to reduce their amplitude to below audibility. This damping is achieved using a multilayer construction that combines multi-thickness MDF panels with a damping layer whose internal friction converts vibration into heat. FinkTeam developed algorithms help specify ideal material thicknesses to achieve the best results, but the ultimate determination is made by subjective assessment.

Enthusiasts spend thousands buying quieter equipment – products that seem to generate (or not in fact) more space between notes to have the effect considerably reduced by noisy loudspeaker cabinets. FinkTeam’s COMSOL modelling and Laser Scanning allow prediction and measurement of the results of cabinet designs.

An example of this was the cabinet opening to mount the 10.25 inch mid/bass driver. Even with the drivers rigidly mounted, there was some unwanted vibration. Almost invisible to the touch test, it was obvious under the laser scanner. A solid metal ring behind the driver mounting solved the problem and increased the signal to noise ratio.


The die-cast aluminium chassis is fully vented for low airspeed, as is the voice coil former. Both reduce distortion and compression.
All this brings a dynamic low-colouration drive unit with high power handling and very low thermal compression.

 

Mid/Bass Driver

As one would expect, Borg’s mid-bass driver is custom designed and manufactured precisely for the purpose.

10.25 inch mid/bass units are relatively unusual. Crossing them well to HF units is not trivial. Still, FinkTeam is a remarkable company: a significant technical challenge is just a design exercise that may take a little longer to solve.

Borg Mid/Bass driverThe benefits of a 10.25 inch mid/bass once heard are difficult to forget. A level of dynamics and naturalness around voices that is unusual and a richness to the sound without bloom or boom (in a well-designed system) that just sounds right. Smaller two-way systems sound anaemic after hearing a 10 inch.

The Borg’s mid/bass unit features similar thinking to the WM-4’s bass driver: low hysteresis surround (it too looks like a pro driver), a sizeable three-inch voice coil for better control and power handling and a low mass stiff paper cone.

Of course, it includes all the regular FinkTeam design essentials: an aluminium shorting ring on the centre pole to reduce voice coil inductance change with position and to reduce flux variation as a function of voice coil current.

AMT HF Unit

The tweeter is an Air Motion Transformer (AMT) operating according to the principles established by its inventor Oskar Heil.

Borg AMT HF UnitDeveloped by Mundorf together with FinkTeam and manufactured specifically for FinkTeam by Mundorf, the AMT has a strong 25um-thick pleated Kapton diaphragm with 50um aluminium strips.

This material has extremely good internal damping, resulting in particularly low distortion. A special etching process was developed to produce it and the diaphragm configuration optimized through a large number of tests.

Given the 10.25 inch mid/bass unit and a lower than average crossover frequency of 1600Hz, a larger AMT driver with a 6464mm2 surface area was ideal. Frequency response easily reaches up to 30kHz while distortion is very low and mainly second harmonic. The AMTs almost constant impedance also facilitates simplified crossover design.
