About the Memphis Audio PRX1524
Rolling thunder
Rolling thunder
Memphis Audio built their Power Reference Series subwoofers to bring strong low-frequency punch into your vehicle. The PRX1524 15" subwoofer delivers big bass and high output, with a heavy-duty suspension that allows this sub to handle up to 300 watts RMS.
Easy to set up, easy to love
This Power Reference Series subwoofer is built to dish it out and take it. Its treated paper cone and double-stitched butyl rubber surround pump out the lows with toughness and precision. Improvements to the coil and suspension design give you even more of that great Memphis sound. Selectable Impedance Technology allows you to select 2- or 4-ohm impedance using the included colour-coded jumpers, making adjustments dead easy and giving you a wide range of installation and system options.
Do you hear a rumble in the distance? That's the bass you've been waiting for on its way to you from Memphis Audio.

Features
Terminals: One pair of spring-post input terminals offers easy connection of single banana plugs, pin connectors, or bare wire up to 10-gauge. The terminals are too far apart for standard ¾" width dual banana plugs.
Selectable Impedance: On the opposite side of the basket from the input terminals, there are four "shorting" terminals. Depending on how the included jumper wires are connected to these shorting terminals, the input terminals present either a 2Ω or 4Ω load. The power handling is the same for either setting: 300 watts RMS/600 watts peak.
Rubber Magnet Boot: A black rubber boot covers the outside edge of the magnet structure to improve the cosmetics of the woofer and protect the magnet during installation. The boot is removable if needed for tight installations. (No change in depth, only magnet diameter.)
Sealed Enclosures: Sealed enclosures provide the most control over a woofer and provide accurate sonic reproduction, making them suitable to all types of music. Memphis Audio recommends a sealed enclosure of 3.0 ft³.
Vented Enclosures: Vented (or ported) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from a given amount of power. Memphis Audio recommends a ported enclosure of 4.6 ft³ with a 15½" x 3" x 29" long port, yielding a tuning frequency of 32 Hz.
Thiele Small Parameters: Some specs change depending on the impedance:

For me this was the biggest bang for the buck when buying a 15 inch sub. Got here quick and was a great price. I'm from Tennessee, and here, Memphis means something!
