Product Description
Manufacturer Part Number: CX120-8
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.
Key Features:
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
Specifications: Power handling: 40 watts RMS/80 watts max VCdia: 1" Le: 0.62 mH Impedance: 8 ohms Re: 6.2 ohms Frequency response: 90-5,500 Hz Fs: 87.5 Hz SPL: 88.5 dB 2.83V/1m Vas: 0.10 ft³ (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
High pass filter required (not included)
Specifications: Power handling: 20 watts RMS/40 watts max VCdia: 3/4" Le: 0.04 mH @ 10 kHz Impedance: 8 ohms Re: 5.6 ohms Frequency response: 4,500-20,000 Hz Fs: 2,745 Hz SPL: 89.2 dB 2.83V/1m Qms: 2.20 Qes: 7.91 Qts: 1.72.
