About the MB Quart PWE 304

The PWE 304 12" subwoofer offers the exceptional performance you'd expect from an MB Quart Premium Series speaker. Its sturdy cast alloy frame suppresses resonances that can distort your bass. And a special-design dustcap strengthens and stiffens the treated-paper cone, so it holds its shape when you crank the volume.

Got enough juice? Get an amp for your new sub The PWE 304 12" subwoofer offers the exceptional performance you'd expect from an MB Quart Premium Series speaker. Its sturdy cast alloy frame suppresses resonances that can distort your bass. And a special-design dustcap strengthens and stiffens the treated-paper cone, so it holds its shape when you crank the volume.

The durable Santoprene rubber surround attaches to the bottom of the cone for enhanced excursion and a clean look. And you can wire up this 12" speaker as either an 8-ohm or 2-ohm sub, so you'll have plenty of options when building your system. MB Quart has created a subwoofer that handles plenty of power and produces deep, clean bass.

Features

Woofer Construction: This MB Quart Premium Series woofer is equipped with a treated paper diaphragm with an inverted parabolic polypropylene dust cap and a Santoprene synthetic rubber, inverted roll surround.

Basket: The PWE 304's motor structure is supported by a high-strength, non-resonant cast alloy basket.

Kapton Voice Coil Former: Kapton is a highly temperature-resistant, completely non-magnetic plastic foil. Because it has no affect on the magnetic field, the woofer provides more precise, distortion-free music reproduction.

Speaker Terminals: This dual-voice-coil subwoofer has a unique speaker terminal which can accept up to 10-gauge wire. The one-piece terminal block holds the speaker wire in place using set screws (2mm Allen wrench supplied). A plastic cover protects the terminal strip from unwanted contact.

Wiring: The woofer can be connected in the following ways:

  • Standard: You can connect the woofer to two separate amplifier channels, and each channel will see a 4-ohm load. Connections are made to the woofer's +1, +2, -1, and -2 terminals.
  • Parallel: You can connect the woofer to a single amplifier channel which will see a 2-ohm load. Connections are made to the woofer's +1, and -2 terminals. Two supplied short terminal jumpers are attached to the terminal block to link together the two positive terminals and the two negative terminals.
  • Series: You can connect the woofer to a single amplifier channel which will see an 8-ohm load. Connections are made to the woofer's +1, and -2 terminals. The supplied long terminal jumper is attached to the terminal block to link together the +2 and -1 terminals.

Logo Badge: The self-adhesive MB Quart Premium Logo badge can be mounted on the top of the screw cover ring in either direction.

Specifications

Enclosure Recommendation: MB Quart recommends a sealed enclosure with an internal volume of 1.0 cu.ft. for this woofer.

Mounting Recommendations: The PWE 304 can only be top-mounted into the enclosure. The supplied self-adhesive rubber gasket should be placed on the woofer to ensure a tight seal. No mounting hardware is included, however, MB Quart recommends M5 hex-head screws and lock nuts. After installation, the supplied screw cover ring can be fitted to the woofer's outer ring for a custom look.

Miscellaneous Specs:

  • Power Handling: 600 watts RMS (300 watts per voice coil)
  • Mounting Height: 0.224" without cover ring, 0.522" with ring installed
