Memphis Audio 15-M615D4
M6 Series 15" dual 4-ohm voice coil subwoofer
Our take on the Memphis Audio 15-M615D4 by Crutchfield's Dominic DeVito
Big bass, Memphis style
From Elvis to Stax, the "Memphis Sound" has always relied on a foundation of deep, rich bass to tie the music together. Now, Memphis Audio brings that bass tradition to your ride with their M6 Series subwoofers.
Ready to pound
Memphis Audio created the M6 Series 15-M615D4 15" subwoofer for high-performance bass reproduction. The fiberglass reinforced cone offers exceptional rigidity so it maintains accuracy at high levels, while its double-stitched rubber surround helps to maximize and control excursion. The vented cast aluminum basket keeps things cool, and virtually eliminates resonances that can color your bass.
Handles plenty of power
The 2.5" voice coils combine with a 120-ounce magnet to handle up to 900 watts RMS, so make sure you feed this sub plenty of power. The dual 4-ohm voice coils allow you to wire the sub for 2 or 8 ohms for system flexibility.
To drive this single subwoofer, we recommend a mono amplifier rated between 650 and 1350 watts at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Dual Voice Coils: This woofer features two 4Ω voice coils, allowing impedance flexibility. When the voice coils are wired in parallel, the woofer presents a 2Ω load. When the voice coils are wired in series, the woofer presents an 8Ω load.
Terminals: The two sets of spring post terminals are on the same side of the subwoofer. They will accommodate bare speaker wire up to 10 gauge. They will also accommodate many single banana plugs, but the post is slightly recessed, so some single banana plugs will not fit well. The binding posts are spaced too far apart to accept standard dual banana plugs (¾").
Sealed Box Volume: Memphis Audio recommends a sealed box volume of 3.0 ft³. A sealed enclosure design gives the smoothest response with increased energy at the lowest frequencies.
Ported Box Volume: The recommended ported box volume is 4.75 ft³ with a 15½" x 3" x 16½" slot port; this yields a tuning frequency of 38 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed, maximizing bass output for a given amplifier.
