Audimax 2 a huge floorstanding loudspeaker with drivers of high quality.

Audimax has been introduced in Hobby HiFi 3/2012. It is one of the best loudspeaker available for DIY. But it is really huge.

The new housing of Audimax II appears less weighty. It reaches very deep bass with passive radiators. The mids have cones made of ceramics with 80 mm voice coil. An air motion transformer Audaphon AMT-1i is used as tweeter.

The cabinet of Audimax II ist built of four single boxes, one placed on top of another.

The crossover consists of 2rd order high-pass and low-pass filters (12 dB per octave slope) .

The frequency response of this speaker a very linear. The decay spectrum is nearly perfect. At medium volume, i.e. 90 dB at 1 m, the nonlinear distortions are lower than 0.1%.

Impedance correction

If you want to use a valve amplifier with this speaker an impedance correction should be employed. In this case the component quality is less important; therefore, we offer only one kit (upon request higher quality components are available).


Price per impedance correction for one speaker, to be mounted on a small wooden board.     EUR 12,00 excl. VAT: € 10.08 / $ 11.39
