Dayton Audio Reference RSS390HF ported enclosure for a single 15-inch driver: 2.06 cu ft net, tuned to 27.5 Hz, 20.6 sq in of port, F3 33.8 Hz.
The 27.5 Hz tuning is where this box is loudest per watt. Protect the subwoofer with a subsonic filter set 5 to 10 Hz below that number, because the port stops controlling the cone under tuning.
20.6 square inches of port area keeps port noise down when the system is pushed.
Listed construction: polyfill installed.
Your subwoofer's mounting depth needs to be 7.01 inches or less. Tell us which subwoofer you run and we will confirm the match first.
