CX3B Bookshelves

3-way Active Bookshelves

Small and elegant form factor with high WAF
3-way design for optimal midrange performance
Completely sealed enclosure with low bass response

They say that necessity is the mother of invention. Or in other words 'without the need for anything, nothing would have been invented'.

We had so many requests for a product like the CX3B's that it was quite obvious the market had the need. So why hadn't it been fulfilled? The answer was simple, it wasn't that easy!

It took 3 purpose designed drivers combined with a highly engineered enclosure and specialised active circuitry to create one of the most linear and accurate bookshelf speakers currently available.

Whilst they do get down low, we don't claim they compare to a large powerful subwoofer. After all, they're a 6" driver! But after listening you may be quite surprised at what we've been able to make it do...

Designed & manufactured in Australia.
