The products of this premium DIY audio brand are produced in North America, Europe, and Asia. Dayton Audio products have received acclaim worldwide throughout the years and are often compared favourably to similar items costing far more.

Dayton Audio woofers

The dominant component in a majority of loudspeaker designs, woofers are responsible for much of a system's tone and character. Don't underestimate this cornerstone element—Dayton Audio has the perfect woofer for every application and budget. Discover some of Dayton’s high-quality audio woofers, such as the popular Dayton Audio Ultimax UM18-22 from the powerful Ultimax Series, the Dayton Audio RSS390HF-4 featuring ultra-low distortion or check out the never-failing Dayton Audio PS95-8 full-range woofer.

Tweeters from Dayton Audio

Although they are the smallest driver in most loudspeakers, tweeters play an important role in our auditory information perception. Clarity, articulation, imaging—Dayton Audio tweeters make your speaker system come alive! Discover the immense popular Dayton Audio air motion tweeters and dome tweeters! Dayton Audio tweeters, such as the Dayton Audio AMTPRO-4, provide ultra-clean, detailed, and dynamic treble output.

Dayton Audio Designer Series

The Designer Series by Dayton Audio was developed specifically with the speaker designer in mind. It is an affordable, attractive line of drivers that puts performance first. Careful engineering ensures that the Dayton Audio DS135-8 5" Designer Series Woofer can handle full rated power at the lowest possible frequencies—without exceeding Xmax. The series combines useful performance parameters with elegant style.

Ultimax DVC subwoofers by Dayton Audio, such as the Dayton Audio UM12-22 woofer, sweep a higher volume of air while preventing false, deceptive reproduction. They are designed to deliver powerful low-end response from modest-sized enclosures.
