Dayton Audio CS622C 6-1/2" Stereo Ceiling Speaker

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

.

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)
