The Dayton Audio MX12-22 Max-X 12" dual voice coil subwoofer is designed to deliver maximum performance at an unbeatable price. It has all the features and performance you expect from a premium subwoofer without the high price tag. The MX12-22 offers high bass output with remarkably low distortion and is designed for use in compact enclosures, making it suitable for both home and car audio systems. With  37.8  mm peak excursion (Klippel tested at 70% Bl) this speaker can move large amounts of air.

• Many inexpensive subwoofers look powerful but do not offer high performance.
• In developing the MX12-22, Dayton Audio has gone to great lengths to keep costs down without sacrificing performance or reliability. A large, inverted dust cap completely covers the rigid pulp paper cone, creating an extremely rigid, layered cone with a sleek and modern look. The narrow but tall custom surround has been optimized to allow for high excursion without reducing the cone area to ensure maximum excursion with improved efficiency. In addition, the surround extends to the back of the mounting flange, providing maximum adhesion surface that easily withstands the stresses of the large excursion. To keep the cone linear, the MX12-22 two spiders at a great distance so that it does not wobble even when it is pushed to its limits.

• High output subwoofers can generate a lot of heat. Excessive heat buildup causes the temperature to rise, which in turn increases resistance. This leads to lower performance, power compression, and premature failure.
• The MX12-22 has everything needed to get as much air through the 2-1/2" voice coil as possible to dissipate excess heat. Six large diameter ports in the diaphragm combined with a widened pole piece opening provide a continuous airflow directly through the center of the voice coil. The outside of the coil is cooled by eight ports under the spider in the frame and six peripheral slit openings in the back plate. This airflow not only ensures that power compression is kept to a minimum, but also that the MX12-22 operates extremely quietly even at high excursions and the mechanical noise that occurs with many of today's subwoofer drivers is virtually eliminated.

• Another problem with many subwoofer drivers in today's price range is the lack of motor power. As a result, the drivers are inefficient or can only produce "one-note bass", which is the result of high Q drivers.
• The massive, double-stacked, high-energy ferrite magnets have been optimized to drive the 2-1/2" voice coil efficiently and precisely. The magnet gap has also been kept tight to ensure the least possible loss of magnetic force. This powerful motor unit gives the MX12-22 an impressive Bl of 21.5 T/m with a Qts of 0.35, making it suitable for use in compact sealed or vented enclosures with excellent bass extension.
  
• With its two 2-ohm voice coils, the MX12-22 can be used in a variety of configurations to help you get the maximum power out of your amplifier in almost any application. In most home theater systems, the coils are connected in series to create a 4 ohm load. When used in automotive audio systems, you have the option of running the coils individually to create a dual 2 ohm load, or connecting them in parallel to 1 ohm to get the maximum power out of today's high current amplifiers.

• Thanks to extensive optimizations and advanced design, the Dayton Audio MX12-22 is an affordable, powerful subwoofer that offers incredible output power and low distortion in a compact size. The Max-X speakers are the perfect choice for building a powerful home stereo system, a high SPL mobile audio system, or a high-quality car audio system without breaking the bank.
