CX4F Floorstanders

4-way Active Floorstanders

The natural design progression from the CX3B bookshelfs was of course a floorstander. Public request was to keep the enclosure slim without increasing the footprint too much more. And so we built the CX4Fs, a 7 driver 4-way system...

Conceptually, they're the bookshelfs with an extended cabinet that houses more bass drivers. But this time we've added another driver type into the mix. A purpose designed paper cone driver to take care of mid-bass duties, allowing the 4 bass drivers below to operate from 80Hz downwards essentially as subwoofers.

Floor bounce is often an issue with multi bass-driver floorstanders and is one of the reasons they're generally known to sound boomy. But not the CX4F! Our onboard active circuitry counter-acts floor bounce and eliminates the problem. Combine this with the critically damped sealed enclosure and we have a bass response most often sought after, fast and tight without being overdone or drawing attention to itself.

Designed & manufactured in Australia.
