Take your sound system to the next level with the Dayton Audio UM18-22 18" Ultimax DVC Subwoofer. This powerful subwoofer is designed to deliver massive low-end power and articulate bass response, making it perfect for car audio systems, home theaters, and music listening rooms.

Ultimate Bass Power

With a power handling of 1000 watts RMS, the UM18-22 can handle even the most demanding audio applications. Its dual 2 ohm voice coils allow for stereo 2 ohm operation, or mono operation in 1 ohm or 4 ohm configurations, giving you ultimate design flexibility.

Design Flexibility

The UM18-22's 3-inch voice coil diameter allows for even more thermal dissipation area, making it perfect for continuous high-power operation. Its dual mirror-imaged linear spiders ensure distortion-free excursion, and its large vented pole piece and under-spider venting provide maximum airflow.

Cabinet Recommendations

For optimal performance, pair the UM18-22 with a suitable cabinet. For sealed enclosures, a 4 cubic ft. cabinet produces an f3 of 33 Hz with a 0.85 Qtc alignment. For vented enclosures, a 6 cubic ft. cabinet produces an f3 of 22 Hz. Larger cabinets and lower tuning frequencies are possible.
