COAX10
Co-axial 10” mid-range w/horn tweeter
Our newly released custom Coax10 center driver, was designed to push the sonic envelope to the edge, but without loosing the organic and emotionally moving presentation, warmth and musicality.
The Coax10 driver features a high-end 10′′ mid-woofer with a light-paper cone and a 1/4′′ Horn tweeter with Polymer dome (similar to our Horn1), but differently from typical configurations, both are mounted on the same axis, aka Coaxial design.
Such an advanced coaxial center driver, with mid and tweeter in the center and woofers in D’Appolito design form kind of a large-size point-source configuration that makes all sound organic, natural and no fatigue with the finest details and nuances while speakers disappear.

“The resolution and nuance retrieval capabilities of the 10” Coaxial driver are pleasantly beyond what I had expected! The larger mid-bass driver and the tweeter are able to send through to the listener as much information from the signal as I hear from the electrostatic, omni, or line source designs I have used.
…The Coaxial driver is so generous that it reveals the quickness in the fingering of the strings, and is plush enough to capture a wide range of detail, from the initial scraping and release of the string to the peak of its vibration. For the better part of twenty years, I have worked to get systems to present the bass line clearly. It is not easy to get an audio system to reveal the bass line distinctly.
…The Trio15 Coax10 is masterful in moderating shrillness, whether instrumental or vocal. In your system, relative to the other PureAudioProject center drivers, the Coax10 will be warmer sounding and riper sounding.
