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.
Highlights
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
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.
