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.

6,000 + (and growing) factories in our existing network are eager to make it for you.
When it comes to selling in stock products, we are no difference from many other Internet retailers, but we take pride in going extra miles to do something special for you: Have some products custom made for you.
We cannot do everything, but we usually can accommodate a certain changes in product options such as color, size, material, or minor design twist. We primarily work with vendors or factories, not individual artist or craftsman. For custom made products, we usually only cater to bulk size order that meets the minimum quantity requirement of a single factory run. Don't be shy. Ask. What we can accomplish may surprise you!
