ALTAN active – concentrated energy

A new star has been born with the new AURUM ALTAN active and this compact speaker takes centre stage: Elegant, top quality craftsmanship combined with state-of-the-art technology means that you now can have everything that your audiophile heart has been longing for.

The active electronics, the rich 200W power and the sophisticated pre-amplifier circuitry have been combined in a superb way to give the ALTAN active the advantages of a small 2-way system with the frequency response range of a mature upright speaker.

You will be captivated by this speaker the very first time you listen to it: Deep, controlled bass, dynamic, non-discoloured mid-tones and high definition as well as brilliant high-tones all provide an unforgettable bond with the ALTAN active. The integrated and well-proven AURUM components also play their part in controlling the system in addition to the integrated amplifier technology: The ALTIMA membrane in the bass/mid-tone drivers ensures naturalness and superb dynamics together with the ribbon tweeter with its incomparable ability to reproduce the music’s finest structures.

For placing the speaker on a stand, we recommend using the DESIGN STATIV G, which is available in black, silver or white.


1. A switchable high-pass filter lets the listener choose between expanded deep bass or increased maximum levels. This can also result in a higher working frequency that clearly reduces strong room resonances below 50Hz. Furthermore, this circuit also produces an additional sub-sonic filter, whereby the speaker is relieved for extremely deep bass. You can see from illustrations 1 and 2 that this filter does not have any effect in its neutral position and the interconnected high-pass for ALTAN and ORKAN can be defined separately.
2. The so-called semi-parametrical equalizer gives you the option of processing a specific small frequency range. The set 1/3 octave bandwidth and the freely selectable frequency and peaks will enable you to make room corrections as well as individual tone adjustments. This will give you a tremendous number of options for eliminating positioning problems, especially when used in conjunction with the switchable high-pass filter.

Why have active speakers?

You only have the option of lowering the SPL in a particular frequency range with passive speakers. This results in a considerable loss of amplifier power and the acoustic engineer is very restricted when it comes to adjusting the frequency responses.
Conversely, many filters and tone controls can be used with an active speaker at very low cost and its own amplifier can be used to directly control the individual sound transducers. This allows to adjust the complete speaker very precisely. An active box will play far more dynamically at the same amplified power as the filter does not cause any losses.
Another advantage, making our active models more efficient is that the owner always has the option of making fine and precise tone adjustments. This means that you can either eliminate any problems arising in a specific room or merely nuance the tone to the type of music being played or to suit your personal tastes.

“Quadral has succeeded in developing an excellent and compact active box. The Altan active should be hidden from your colleagues because of its superb appearance, never mind its sound!

Active box fans will get tremendous hi-fi value at a price of 2,800 euros per pair.”

+ Realistic and exceptional sound & workmanship.

Audio Recommendation, Homogeneous image, December 2013



With the Altan aktiv Quadral Aurum deliver an impressive debut in the compact active speaker category. With its three-stage bass roll-off, assignable notch filter and treble trim the featurization is real-world practical and the sound relative to price and size is a real hammer. Meanwhile the lot is elegantly packaged and finished flawlessly. I'd be surprised if this model wasn't a success to prompt further active offspring from this Hannover firm.
