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 Mk5 Bookshelf Speakers

For a big sound from a small speaker, the Equinox Mk5 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 (minimum 3.6 Ohms)
- 45Hz > 40kHz Frequency response
- Rear vented enclosure with internal bracing

Krix Seismix 3 Mk7 Subwoofer

For a deep bass experience that will move the earth without costing the earth, the Seismix 3 Mk7 subwoofer is sure to rock your world. You won’t have to sacrifice musicality for low frequency output with this tuneful speaker that will allow you to truly feel the rumble of bass with supreme clarity.

A front-firing, vented subwoofer, the Seismix 3 Mk7 features a Krix designed 275mm (11") long throw bass driver, developed specifically for high-level low frequency reinforcement. Enhanced geometry within the magnet structure increases linear cone travel by a whopping 30 percent and allows superior driver control, while the built-in high performance class D amplifier delivers increased sound efficiency with lower power consumption.


Key Features:
- 1 x 11" bass driver, 2" voice coil
- Power Handling: 300W RMS
- Frequency Range: 22Hz-200Hz in-room response
- Output: 122dB maximum SPL in-room response
- Enclosure Type: Bass reflex, front firing, front ported
- Low Pass Filter: 50Hz-200Hz or bypass
- Phase Select: 0º to 180º continuously variable (relative to input signal)
- Inputs: Stereo line-level RCA



[Optional] Make it a Dolby Atmos pack with additional speakers!

If the Equinox bookshelf speakers aren't quite what you want or you're looking for a Dolby Atmos speaker setup (5.1.2), you're welcome to select a more discreet option instead: the Krix Atmospherix AS in-ceiling speakers.

Part of the Krix Architectural Series, the Atmospherix AS is tonally balanced to the Krix floorstanding and bookshelf speaker ranges, making it an ideal speaker system for matching with a Krix home theatre. A large 130mm (5") bass driver with large magnet and copper shorting ring delivers bass and midrange clarity, while a 26mm (1") ring radiator provides extended high frequency performance.

The moving components of the Atmospherix AS are protected from dust and debris through a fully-enclosed back box, designed to optimise the performance from the bass driver, allowing maximum controlled bass and consistency while drastically reducing sound leakage to other rooms. The attractively styled, slim bezel grille is made from rust-resistant stainless steel and snaps into place with magnets, making installation easy. Being paintable, these speakers will involve you in their sound, while disappearing to be heard, but not seen.

Key Features:
- Sound directed toward your listening position
- Easy install
- Discreet home cinema
- 45Hz - 40kHz in-room response
- 90dB sensitivity
- 5 inch, 2-way speakers
- 1" ring radiator tweeter
