Koloss leads us to the limit of the sound. Stunning from every angle, it is characterized by its large, widespread and deep sound. It 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.


Koloss stands out for its prominent, large and wide performance. It is a wonderful speaker that can play magnificent sounds with unique accuracy and detail. Latest generation technology provides a superb sound quality optimized to play in perfect balance. It redefines the listening experience to a new level of perfection.


In Koloss™ we can observe a classic geometric structure, with fine vanguard details that provide its freshness. It has a considerable size, exactly 555 x 215 x 240 mm. The curved sides enable the light to be distributed smoothly through the edges. Its natural structure seeks to please senses through purity.


This technology provides smooth treble sounds, with extreme definition and sharpness. Cutting edge materials help extend the tweeter's operating range above the audible spectrum. Enjoy the subtlety and every detail of the sound.


This technology extends low frequencies to deliver a deep and powerful sound. This exclusive development of our R&D department allows sound to acquire a robust and voluminous character, while maintaining it clear and natural. Experience the beat of the bass, the power of sound.


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


It is a technology that allows you to isolate the sound of external interference, allowing a pure and crystal clear sound flow without noises’ irruptions.


This protective cloth works as a shield,protecting the drivers from any damage and from all kinds of harmful agents. This helps to take care of both sound quality and equipment performance.


The Bass Reflex Sound enhances the sound expelled through the rear of the diaphragm. This way the resonance system increases the bass response of the controller and optimizes the efficiency and performance of low frequencies.


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.


Bluetooth is the technology that allows this connection between devices. We use it to pair our speakers with playback devices, tablets, phones, MP3 players and laptops. Music, movies, TV, video games and social content with amazing sound.


Thanks to RCA stereo input you can connect your device to your computer easily to any player device that has stereo output: tablet, smartphone, notebook, pc, tv.


This type of digital connection reduces electrical noise interference, improving the quality of the signal received by the speaker and providing a pure and crystal clear sound.


On the control panel, you´ll find volume control, bass and treble controls, mute button, playback source selector, Bluetooth, RCA and SPDIF optical. It’s perfect for centralizing the management, enabling better spatial arrangements for the speakers.


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.


This technology allows greater precision in frequency-division, improving qualitatively and quantitatively the system’s response.


DSP technology optimizes playback of sound using digital processing. Removes noise and distortion, allowing you to hear crystal clear voices and music.

Auto Level Control (ALC):

This circuit adjusts the amplifier’s gain to a fix value when the input level exceeds a predetermined limit. This allows maintaining a low level of distortion even when using the maximum volume.


Saving energy is part of the preservation of the environment, one of our main goals. That´s why our equipments have an on/off switch that completely interrupts power to the equipment. This allows energy savings when the speaker is not being used.

I bought these for listening to Blues and Jazz music. I'm a Jazz aficionado, hence every note matters a lot to me. These speakers deliver just as promised, that too in a compact size. I can listen to classics without really having to tweak the eq. Yes they are that good. Thumbs Up


i purchased this set since i wanted to try something new apart from the regular ones available in the Indian market. From the moment i switched it on, i've been nothing less than thrilled and excited to play music on it again and again. The sound quality is crisp and clear, and it has really good aesthetic appeal overall. Thank you bajaao for making it available in india!
