- Krix Vortex Mk2 Centre speaker
- Krix Equinox Mk3 Surround bookshelf speakers

Krix Harmonix Mk2 Floorstanding Speakers

The Harmonix floorstanding speakers are equally brilliant at making movies sound amazing, but are also ideal for music listening.

These 3-way speakers feature two hefty 165mm (6.5") bass drivers in an extended bass shelf alignment, providing deep, tight bass. A dynamic non-fatiguing vocal mid-band is delivered by a 130mm (5") midrange driver, and lucid, detailed highs come from the 25mm (1") super audio tweeter with an extended frequency response up to 40kHz.

Producing a truly natural, all-encompassing sound, the Harmonix Mk2 features front facing ports which allow the speaker to be pushed up against a wall without compromising sound quality. They are also timbre matched with all Krix speakers for surround sound fidelity and come in a range of elegant cabinet finishes for definitive style and flexibility.

Key Features:
- 2 x 6.5" Bass/Mid Drivers with 1¼" voice coil
- 5" Mid range Driver
- 1" dual concentric diaphragm with wave-guide tweeter
- Power Handling: 50 - 250 Watts RMS
- Nominal 6 ohm impedance
- 35Hz > 40kHz Frequency response
- Dual chambers - sealed midrange chamber with bass reflex main chamber
- Front vented with internal and external flaring
- Dual gold plated bi-wire binding posts
- 28kg each


Krix Vortex Mk2 Centre Speaker

The Vortex Mk2 delivers vocal clarity, midrange depth and a dynamic bass response. The vertical arrangement of the tweeter and midrange drivers eliminates phasing problems if seated off-axis, ensuring even sound distribution so that every seat in the room is a good one.

Big, dual 165mm (6.5") bass drivers come with heavy-duty voice coils, wound on high-powered aluminium formers, while the 130mm midrange driver has an oversized magnet for lower distortion. The 26mm high frequency driver, with its wave-guide plug, also ensures controlled directivity.

Key Features:
- 2 x 6.5" Bass Drivers with 1¼" voice coil
- 5" Mid range Driver
- 1" dual concentric diaphragm with wave-guide tweeter
- Power Handling: 50 - 250 Watts RMS

Krix Equinox Mk3 Bookshelf Speakers

For a big sound from a small speaker, the Equinox Mk3 will astonish and surprise. With finesse and power punching well above its weight, it can be tucked-away while still filling the room with sound.

The mid-range and bass come from a high grade 130mm driver with a doped curvilinear paper cone, over-sized voice coil, and powerful magnet, while extended frequency response is delivered through a 26mm ring radiator tweeter. Combined with its bass reflex design, the result is an efficient but balanced bass sound with a revealing, detailed high end, performing well beyond the relatively small cabinet size of the speaker.

Key Features:
- 5" doped curvilinear paper cone woofer
- 1" dual concentric diaphragm with wave-guide tweeter
- Power Handling: Maximum 120W RMS
- Nominal 6 ohm impedance
- 45Hz > 40kHz Frequency response
- Rear vented enclosure

Krix Tektonix Subwoofer

Featuring the Krix sub amplifier with ICEpower® technology, the Tektonix delivers even greater levels of power and efficiency for distortion free bass.

Winner of Sound & Image Magazine's 2012 "Product of the Year, Subwoofer  Under $2,000" Award.

Feel the rumble as the quake strikes or the orchestra hits its crescendo. Expertly fitted into Krix’s popular Seismix 3 cabinet, the Tektonix is a reasonably compact subwoofer that is not only musical but it also delivers the deep bass movie experience that creates a truly real, “right there” feeling. What’s more, the front mounted digital control panel simplifies set-up and adjustment control.

The Krix designed amplifier with ICEpower® class D technology delivers power and efficiency, while the unique 275mm (11") long throw bass driver developed specifically by Krix, provides the earth moving bass. Easy to access controls sit behind the grille to avoid any jostling when adjusting settings, while an easy scrolling menu makes it as simple as pushing a button. The back-lit LCD display also fades within 45 seconds, to ensure nothing gets in the way of your movie viewing experience.
