Ohm
The Dayton Audio Reference Series sets a new
standard of value in high-performance loudspeaker drivers. Utilizing a
low-distortion motor system with two short-circuit paths and a rigid aluminum
cone, the Reference Series can outperform drivers that cost several times the
price. Their low-distortion characteristics and high excursion capabilities
provide exceptional clarity, detail, and dynamics. Woofer features a black
anodized cone, heavy-duty 6-hole cast frame, low-loss rubber surround, solid
aluminum phase plug, and gold terminals.
