Krix Hemispherix A20 5.1 Pack

This discreet In-ceiling 5.1 speaker system features Australian Made speakers from award-winning loudspeaker manufacturer, Krix. This package of in-ceiling speakers are not only designed for a minimal modern look, thanks to Krix's specially designed back-boxes they also have quality sound to make your living room sing. The Atmospherix A20 speakers feature angled drivers to aim the sound towards the seating position providing a more direct soundstage from in-ceiling speakers.

What's Included:

- 3x Krix Hemispherix A20 Front & Centre In-Ceiling Speakers
- 2x Krix Holographix Surround In-Ceiling Speakers
- 1x Krix Seismix 1 Mk5 Subwoofer


Krix Hemispherix A20 In-Ceiling Speakers (x3)

The little brother to the Atmospherix A20, these in-ceiling speakers feature angled baffles behind the slim magnetic grilles. The Hemispherix A20 speakers direct sound towards your seating position for improved clarity in high definition music and movies.

Superior to traditional in-ceiling speakers, the Hemispherix A20s make your experience clearer and more powerful. There is a more three-dimensional soundstage, better definition for music listening, more articulate dialogue, and more realistic and involving sound effects in movies.

The fully-enclosed back box maximises and controls bass, protects from ceiling debris and drastically reduces sound leakage into adjoining rooms. With speaker components mounted directly to the front baffle of the speaker, the Hemispherix A20 delivers a true high fidelity sound in a neat package.

Key Features:

- Sound directed to your listening position
- High fidelity performance in your ceiling
- Fully-enclosed back box
- 4" doped paper cone woofer
- 0.75" ring radiator tweeter
- Power Handling: 20 - 100W RMS
- Nominal 6 ohm impedance
- 65Hz > 40kHz Frequency response
- Bass reflex, front vented

Krix Holographix In-Ceiling Speakers

With a smooth, accurate frequency response and good low frequency extension, the Holographix deliver the kind of high quality performance you wouldn’t usually expect from a speaker this size (about the size of a downlight!), thanks to the full range 75mm polypropolene cone and corresponding large voice coil and magnet. At only 108mm mounting depth, the Holographix will fit in most roof cavities, with a simple twist-and-lock mounting system making installation a breeze.

Multiple pairs can be wired together for even sound distribution over large areas and can be easily painted to blend in to your colour scheme. When lined up with downlights or set in each corner, they virtually disappear, for a surrounding background sound you can hear but can’t see.

Key Features:
3" Polypropylene cone, neodymium magnet
Power Handling: 10 - 80W RMS
- Power Handling: Maximum 120W RMS
- Nominal 8 ohm impedance
- Frequency response: 90Hz > 20khz
- Acoustically treated infinite baffle
- About the size of a downlight
