Aretai Contra 100S

A highly detailed and revealing soundstage with a surprisingly low yet impactful bass character that's entirely unique in this size category. 

A precision full-range performer

Designed for smaller and medium-sized rooms, the compact Contra 100S are quite unusual speakers, allowing you to “see” each instrument located right where the recording engineer intended it to be.

The unique and innovative filter design, bi-pole radiation pattern and the closed type enclosure enables Contra 100S two 6” drivers to deliver a surprisingly deep and well-textured bass combined with a coherent midbass and treble balance.

The bass response of this 2.5-way speaker extends down to 30Hz. To eliminate shifted phase summation typical for ported systems of similar size we deliberately designed a sealed enclosure to keep the bass perfectly tight.

Our custom-designed waveguide delivers a soundstage of impressive depth and width. The neodymium tweeter delivers pristine, undistorted clarity up to 25kHz even at higher volume levels.

To give your experience that extra edge, our bi-amping terminal option allows you to use two amplifiers for separate HF/LF amplification paths.

"Comparing the Aretai with an admittedly
more affordable pair of speakers was a bit like 
contrasting an oil painting with a cartoon.
