Dayton Audio RS75-4 3" Reference Full-Range Driver 4 Ohm

The Dayton Audio Reference Series sets a new standard of value in high-performance loudspeaker drivers. Incorporating a low-distortion motor system with a copper ring, a copper cap, and an aluminum phase plug, the RS75-4 can outperform "boutique" drivers that cost several times the price. Its low-distortion characteristics and smooth response provide exceptional clarity, detail, and dynamics. Features a black anodized cone, heavy-duty 4-hole cast frame, low-loss rubber surround, and gold terminals.
