Gauder Akustik was founded in 1997 by Dr. Roland Gauder and Achim Knapp and every pair of Gauder Akustik speakers are hand made in their Renningen, Germany factory.
The Capello 100 are a 3-way bass reflex design comprised of an aluminum tweeter and Gauder Akustik XPulse 7″ midrange and 2x 7″ bass drivers in a bottom-ported ‘drop’ shaped cabinet. The review pair, and every pair sold in the US, come with Gauder Akustik’s Double Vision Gen II Symmetrical Crossover, Big Foot Spike Kit, and upgraded Aluminum Tweeter. The DoubleVision version adds “even more finely selected components from Mundorf, higher quality internal wiring, top quality WBT terminals and rhodium-plated bi-wiring bridges.”
The review pair of Capello 100s are finished in a black Piano high-gloss lacquer making them stealthier than a mirror and more difficult to photograph. Other finishes include a white Piano high-gloss lacquer and Olive and Walnut veneers. The Capello 100 have a claimed frequency response of 27-30,000 Hz with a 90dB sensitivity and 4 Ohm impedance.

I encourage you to take a long look at the Gauder Akustik website as they dig into some detail behind these technologies including their Time Delay Control. Here’s a snippet form the website:
As our speakers all have very low crossover frequencies from the bass to the midrange (120 Hz – 166 Hz) and the ear is very insensitive in the bass range, there is no need for a time delay between the midrange and the bass. In addition, instruments in this frequency range naturally resonate much more slowly than the time difference generated by the coils.
Thanks to the uninterrupted reproduction with TDC, there is no longer any distortion even in the acoustic phase of the loudspeaker and the music detaches itself wonderfully from the loudspeaker and plays from “wall to wall” in the listening room – resulting in a perfect illusion of spatial sound.
The TDC technology in combination with our ultra-steep crossover filters creates perfect impulse reproduction for the first time in hi-fi history and can absolutely be described as a game changer.
Around back we find two sets of speaker binding posts to allow for bi-wiring or bi-amping and two sets of jumpers for adjusting “Bass Control” and “Bass Extension”. Bass Control allows for an increase or decrease in bass response ± 1.5 dB.
The review pair of Capello 100s also shipped with the Bass Extension Modules, in a very nice wooden box, that allow for further adjustment as follows:
No Jumper: 0 dB
Red Module: + 1 dB
Blue Module: + 2 dB
Green Module: + 3 dB
White Module: +3.5 dB
Jumper Plugged: + 4 dB
These modules simply plug into those Bass Extension slots. The company provides more informationon Bass Extension in the manual:
All our loudspeakers are highpass-filtered. This means that there is always a capacitor in the signal lead. A highpass-filtered closed-box or bassreflex system is of higher order than the usual systems and therefore have a better performance: they have a lower f3-point (lower bass enhanced), have a higher efficiency and need a smaller cabinet volume. Such systems use the amplifier as source of energy which for digital amps, transistor amps or big tube amps is not a problem. If you do not use such an amp to drive the speaker you can pull out the “Bass Extension Jumper” and deactivate the system (plugged jumper is 4 dB amplification). The impedance then rises up to 10 Ohms and more in the low-bass region and requires much less power from the amp.
Moreover, if you place the speakers close to a wall or in a corner then the low bass is also enhanced enormously. Reducing this low bass frequency range by pulling the Bass Extension jumper is also an appropriate way to reduce this problem easily.
I plan to try every combination with all kinds of amps. Stay tuned!
