The Dayton Audio PS Series drivers do it all: true bass, articulate
midrange, and balanced, extended highs.
Key Features
High sensitivity/minimal distortion—an ideal match for lower powered
amplifiers
Parasitic HF cone and carefully engineered phase plug extend on- and
off-axis response
Solid bass performance, thanks to usefully high excursion capability (4.8
mm Xmax)
Optimized neodymium magnet provides high motor strength
Low-mass copper clad aluminum voice coil
Copper cap and copper ring on pole piece reduce inductance and
distortion
Kevlar reinforced paper cone is lightweight yet rigid and well
controlled.
The Dayton Audio PS Series drivers do it all: true bass, articulate
midrange, and balanced, extended highs. An intensive program of design and
testing has yielded full-range speakers that feature high sensitivity and smooth
response, both on- and off-axis. Although an ideal match for lower powered Class
A and Class T designs, the PS220-8 8" driver's superb resolution and natural
sound quality make it a viable option for an even wider variety of applications.
The PS Series' audio performance is complemented by the speaker's striking
appearance—they look great in dipole and other open back designs, too!
