Krix Ultraphonix Series SX Pair Surround Loudspeakers

Call to order

Perfection can take time

Krix speakers are usually made-to-order in South Australia, with construction beginning once your order has been placed. This process ensures great attention to detail is applied to each and every speaker, but it can also take time — sometimes around 2 weeks.

A premium product like this deserves the personal touch, so we would love to speak with you to ensure everything is perfect from start to finish. Please feel free to call us (or visit us in-store) to discuss your new system.

Experience Immersion

For powerful home cinema sound that is sensitive enough to produce a whisper but controlled enough to reduce distortion on loud on-screen effects, the Ultraphonix is the perfect partner to your home cinema system.

A dedicated home cinema on wall side and rear surround speaker, the Ultraphonix offers high power handling and high sensitivity with low distortion, as well as bass extension down to 40Hz. Replicating the wedge-shaped design used in Krix’s commercial cinema surround speakers with a 15-degree baffle, the Ultraphonix can be mounted high and away from the listener to maintain excellent pattern control and audio coverage to all listening positions.

The massive 205mm bass driver featuring a 38mm voice coil has been developed to provide the smoothest possible response with a dynamic and non-fatiguing vocal mid-band. The high frequency drive unit is a specially-damped, high power, 26mm doped fabric dome tweeter that combines with the bass driver via a crossover network that has been designed and built using close-tolerance, professional-grade components, for an exceptionally smooth and well controlled sound.

Complete with an enclosure that is braced, critically-damped, and finished with a neat black cloth grille, this on wall speaker has it all.

Key Features:
- On wall surround speaker
- 15 degree angled baffle
- High sensitivity, very low distortion
- Grille and keyhook mount included
- Sold as a pair
