    Product description

    With a natural sounding 3/4" soft dome tweeter concentrically mounted in a long throw poly cone 4" woofer Dayton Audio's CX120-8 will produce extremely smooth response on and off-axis while avoiding the phase and lobing issues associated with standard 2-way designs. This driver is perfect for compact designs, portable speakers, or even custom car audio systems.



    • Full-range with accurate bass and extended high frequency response
    • Coaxial mounted 3/4" silk dome tweeter
    • Open cast frame for improved air flow and minimal power compression
    • 4" curvilinear poly cone woofer with rubber half roll surround

    Dayton Audio CX120-8 4" Coaxial Driver with 3/4" Silk Dome Tweeter 8 Ohm


    The Dayton Audio CX120-8 is a full-range coaxial loudspeaker providing high quality sound in a very compact format featuring a 4" curved linear poly cone woofer mated with a 3/4" silk dome tweeter. The poly cone woofer provides a good balance between stiffness, low mass and damping making for a very natural sounding driver with a smooth frequency response. The silk dome tweeter provides detailed and clear high frequencies with minimal distortion. In addition, the optimized tweeter placement and flaring reduces the phase issues with the woofer that is commonplace with even the BIG brand coaxes. Designed for use as a full-range in a small bookshelf speaker, an extended range (i.e. midrange/tweeter) driver in a 3-way system, or even car audio systems.


    4" Woofer:

    • 1" voice coil wound on an aluminum former for high power handling
    • Curved linear shaped poly cone provides a good balance between stiffness, low mass and damping making for a natural sounding driver with a smooth frequency response
    • Optimized rubber surround for reduced break up in the midrange band
    • Attractive rigid open cast frame cast frame to minimize reflections, resonances and improve air flow
    • High energy ceramic magnet for greater cone control and improved efficiency

(2.99 liters) • Qms: 2.89 • Qes: 0.57 • Qts: 0.48 • Xmax: 3.0 mm • Dimensions: Overall diameter: 4-3/4", Cutout diameter: 3-7/8", Depth: 2".


    3/4" Tweeter:

    • Silk dome provides detail and clarity of high frequencies
    • Coaxially mounted to pole piece of woofer cone
    • Optimized placement and trimmed flaring to reduce phase issue interaction with woofer
    • Strong neodymium magnet
    • Trimmed flared throat to minimize phase issues causing suck-out with woofer

    Nice and resolving rivers. I have not noticed the IMD issues that many warn about using coaxials. Using them in a 1.6 liter sealed enclosure with a subwoofer.
    Imaging and separation is some of the best I have heard and the frequency response is nice and even with a simple 3 component crossover. These drivers in the right enclosure sound very "high-end".

    very detailed sound from this speaker even at loud volumes. Was surprised by the clarity. Suitable for small to medium size speakers and does exceptionally well in portable projects since it eliminates the need for a midrange woofer and tweeter. So basically less components and no crossover needed. Only bad thing is that it isn’t available as a 4 ohm version.
