About the Memphis Audio MJM822

Bob Bihlmayer

Over 100 years of heritage

With deep roots in over a century of country-blues and jazz, it's no surprise that Memphis saw the beginnings of modern blues, rock and roll, soul, and alternative rock, and it's no accident that all these styles of music rely on powerful, evocative bass lines. Memphis Audio's MOJO Series subwoofers bring this tradition to life with low end to make your feet move and your spirits soar in a speaker that fits a broad variety of installations.

Features

Dual Voice Coils: This woofer features two 2Ω voice coils, allowing wiring flexibility. When the voice coils are wired in parallel, the woofer presents a 1Ω load. When the voice coils are wired in series, the woofer presents a 4Ω load.

Terminals: The two sets of spring post terminals are on opposite sides 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.

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 0.6 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 1.0 ft³ with a 3½" diameter x 16" long port, yielding a tuning frequency of 39 Hz.

Q
Can you tune lower to 33 hertz?

A
Memphis does not advise tuning lower than 39Hz for this sub.

Q
What would you recommend for a amplifier for just 1.?
marvin  Dec 07, 2022

A
If you are just planning on a single Mojo 8" subwoofer Robert, you'll need something in the 8-900 watts RMS range at 2-ohms. The MTX Jackhammer JH10001 in the first link is a solid contender, and if you need something in a small physical footprint the Soundstream Reserve RSM1.4000D in the second link packs a major punch in a small size. Both these would sound great pushing the single Memphis Mojo 8"! https://www.crutchfield.com/p_236JH10001/MTX-JackHammer-JH10001.html https://www.crutchfield.com/p_530RSM1400/Soundstream-Reserve-RSM1-4000D.html

Q
How do these really compare to the Sundown 800 watt 8 inch?
jabaar  May 23, 2022

A
I wish I had better news, but since we don't carry Sundown products we have never been able to compare the Memphis Audio MJM844 to the 8" Sundown sub to give you an idea of how they stack up against each other.

Q
What size screws do I need to mount these. I have 2 of the 8" mojo Mini's and the screw holes look much smaller than what I'm used to or do I just drive a normal size wood screw through the rubber looking hole on the sub?
josh  Apr 02, 2022

A
We do not have information on the screw size that will work with the 8 holes on this subwoofer and I cannot find it in the owner's manual. You might check with Memphis Customer support to see if they can supply that information. We have 800-903-6979 for their support phone number

Q
Will a kicker cxa800.1 be a good match for this sub?
wyatt  Mar 20, 2022

A
Thanks for your question. For information on selecting the best amp/sub combo I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.
