The power of paper

There's a reason that most electric bassists use paper speakers – it sounds warm! Memphis Audio uses a coated paper cone with a double-stitched butyl surround to build a sub that creates classic bass tone while still standing up to the power demands of today's bass-heavy music. The dual 4-ohm voice coils allow you to get maximum punch from your mono amp.

To drive this single subwoofer, we recommend a mono amplifier rated between 150 and 300 watts at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Great factory replacement

Scott N from SoCal on 10/5/2016

2001 Chevrolet Suburban

Verified customer (What's this?)

Bought this to replace blown factory sub driven by factory amp. To be placed in factory box. Wired it in parallel for 2 ohms. Only difficulty was it was a tad too deep to fit in factory box. Since factory sub had a cardboard collar that stood out from box I figured I might have enough space behind interior panel to bring the speaker out a bit. I made a spacer ring out of mdf and voila, all good. So nice to have some bases back in the system. And much cleaner than factory sub. It's not a 12" thumper but it does the job in our vehicle just fine.

Pros: Good value. Good sound

Cons:

Features

Dual Voice Coils: This woofer features dual 4Ω voice coils, offering wiring 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.

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.

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 volume of 0.45 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 less power. Memphis Audio recommends a ported enclosure volume of 0.7 ft³ with a 2" diameter x 5-3/4" long port, yielding a tuning frequency of 43 Hz.

Q
Can this woofer replace the 8" woofer in the Memphis subwoofer model SA108SP?

Hi Bruce, thank you for your question. I would recommend reaching out to Memphis Audio to check for replacement parts, or to obtain servicing on that powered subwoofer. Replacing the subwoofer of that setup with the Memphis Audio 15-PRX8D4, would not be recommended. You can reach out to Memphis Audio at 800-903-6979. If you would like to speak with an Advisor regarding the purchase of a new powered sub, feel free to chat with us online, or by phone at 1-800-324-9695.
