    Exquisite And Elegant

    This bookshelf speaker has a classic geometric structure and considerable size, designed to fill any room with the best sound. It is a device that can overcome all barriers, and it’s the perfect balance between purity and extreme power.

    The Best Home Audio

    This 2.0 speaker stands out for its power and sound quality, not only because its precision, but also because its able to reproduce in detail the full range of sounds.

    HDAA™ Wood

    It is a natural polymer of high density that generates a rigid and dense material. These properties prevent vibration and leakage of sound, enabling a more accurate, efficient and sustainable performance.


    This protection allows safeguarding the drivers from any damage and of all kinds of harmful agents. This ensures both sound quality and equipment performance.

    Bass Reflex

    It is a resonance system that increases– the bass response of the controller and optimizes the efficiency and performance of the low frequencies.

    Side Panel

    Ergonomic controls are made of cutting edge materials, which allow optimizing the selection range by regulating in a precise and detailed way the volume, bass and treble.

    Remote Control

    The speaker has a wireless remote control. This allows you to turn it on, select the playback source, raise and lower the volume, adjust bass and treble, use the mute function and reset the selected EQ setup without approximating the speaker.

    On/Off Power Switch

    The preservation of the environment is one of our main goals. That´s why our speakers have an on/off switch that completely interrupts the power supply. This allows energy savings when the speaker is not being used.


    Its 1 inch tweeter is made entirely in silk. This type of fiber is known for being very light and responsive, allowing reproducing treble frequencies in a pure and crystalline way. The suspending ring also contains silk, which optimizes the accuracy by allowing extremely thin beats.


    The speaker has two 6.5– inch woofers made entirely of aramid fiber in its characteristic yellow color. This material is extremely rigid and light, enabling a high performance. The upper suspension ring is made of highly elastic rubber, allowing larger displacement sensitivity and resistance to the beats of sound.

    Rage Bass™

    RAGE BASS™ extends low frequencies to deliver an extremely deep and powerful sound. This way, sound acquires a robust and voluminous character, while maintaining its clear and natural note.

    Glow FX™

    GLOW FX™ provides smooth treble sounds, with extreme definition and sharpness. Cutting edge materials help extend the tweeter's operating range above the audible spectrum.
