Product Details

Dayton Audio QT385-4 15" Quatro Subwoofer 4 Ohm

The Quatro™ Series subwoofers have been designed and built based on the well-respected platform of the Dayton Series II woofers. By implementing a 4 ohm voice coil and extending the excursion capabilities, the Quatro™ woofers now become serious contenders for home theatre and automotive use. The long excursion design and high sensitivity allows you to take advantage of modest power amplifiers, while the relatively high DC resistance makes them very friendly to 4-ohm stable amps and will not cause overheating or other amplifier stability problems.
