Dayton Audio - DS115-8 - 4" Designer Series Woofer Speaker - 8 Ohm

Brand NEW!  
Including 90 Days USA Factory Warranty.
More than just a pretty speaker, the Dayton Audio Designer Series DS115-8 4" woofer features an extremely neutral response and high Xmax capability.
Key Features Coated paper cone, half roll rubber surround for durability and accurate reproduction Cosmetic frame with low profile lip, designed for front mounting—no countersinking required! Optimized to yield a low 3 dB down point and high potential output in a reasonably sized cabinet Vented pole piece for minimized power compression and maximized reliability Generous Xmax capability encourages use of moderate bass boost to tailor the response Smooth frequency response and linear roll-off simplify filter design, assuring good results with off-the-shelf crossovers Retains the same "family look" as the popular Dayton Audio DVC Series subwoofers and passive radiators  
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 each speaker in the series is capable of handling full rated power at the lowest possible frequencies—without exceeding Xmax.  
These speakers combine useful performance parameters with elegant style. Carefully optimized to provide superb audio reproduction when incorporated into a wide variety of enclosures and alignments, the Designer Series transducers put a beautiful face on audiophile excellence.  
• Suggested enclosures:
