Krix Cyclonix 18 Passive Series SX In Room Subwoofer

Ships in 2 to 3 weeks

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.

Krix Cyclonix
The Krix Cyclonix offers a unique solution for those seeking to recreate the lowest possible audible frequencies in their home cinemas. This is achieved through the use of a high excursion 18 inch bass driver, featuring a 4.5” coil, powerful vented magnetic circuit, optimum cooling system which provides fast heat exchange, reduced thermal power compression and double spider assembly. Mounted in a dual front vented enclosure and tuned to achieve maximum output, the result is an incredibly efficient subwoofer for high drive level applications. Being front vented, the Cyclonix is room friendly and can be easily mounted into a false baffle wall or behind an acoustically transparent screen. The enclosure is constructed of high quality MDF and heavily braced to eliminate panel resonances. Complementary speakers: Scenix, Fanatix, Megaphonix Flat, Dramatix, Phonix, Ultraphonix, Megaphonix.

Key Features:
- In room subwoofer
- High excursion 18" bass driver
- Incredibly efficient for maxiumum output
- Heavily braced enclosure
