Building upon the acclaimed and well received Fader Series studio monitors, Fluid Audio launches
the FPX (Fader Pro Coax) series. The new FPX-7 Studio Reference Monitor, featuring the world’s first coaxial driver with ribbon tweeter, leads the way.

The Fluid Audio FPX7 produces the most accurate monitoring experience in it’s price range. With it’s lightning fast response, the AMT (ribbon) tweeter provides detail and depth only seen in Professional studios. What makes the FPX7 so unique, however, is that the AMT tweeter is mounted in the center of the woofer, which makes this speaker the first of it’s kind.

Coaxial drivers provide accuracy and detail because all the frequencies radiate from the exact same position in space. This is critical for accurate off-axis response, as well as phase coherence. The AMT tweeter is mounted to a custom designed waveguide, which provides wide dispersion and an expansive sweet spot. The complex, DSP controlled crossover provides a perfect blending of the woofer to the AMT tweeter, and ensures that there is effectively zero variance speaker-to-speaker. The “engine” is DSP powered.

“Ribbon tweeters have certainly been used in studio monitors before. It’s a perfect use for them, actually.
However, I’ve never been that impressed by previous executions of the idea. I’ve always felt I could do a
ribbon monitor that sort of set the standard for ribbon monitors, and I believe this coax idea does that.
You get the lightning fast response of the ribbon, and the point-source goodness of being coaxial. As a
recording musician myself, I was always a little frustrated with the way a lot monitors would ‘Hi-Fi-ize’ my
live recordings. I would record something live in a room, but played back through the monitors, it already
sounded kind of slow and dull. With our new AMT ribbon tweeter, you get that immediate, live sound that
you recorded. That, coupled with the low distortion woofer and great off axis response of the FPX7, you have
a clear, honest view into your mixes,”
says Bill Loney of Fluid Audio.
