A look at the twin down-firing subwoofers

The anchor of your in-cabin audio system

The MS-AB206 features a 6" dual voice-coil, down-firing woofer and a matching passive radiator for exceptional bass reproduction. The passive radiator is used to augment the output the 6" driver for better low-frequency performance from a truly compact enclosure.

A built-in 4-channel Class-D amplifier delivers high output and high efficiency. Two channels are dedicated to the subwoofer, while the other two channels are tuned to power Fusion's MS-BX3020 cabin speakers -- a highly-recommended combo that sounds great in any boat.

This sub is designed for cabin use, but Fusion still engineers it to withstand moisture and heat just as well as their outdoor marine speakers. This rugged speaker is backed by Fusion's True Marine 3-year warranty.

Product Research

Features

Overview: The Fusion MS-AB206 is an active subwoofer designed for marine use. The subwoofer features a down-firing 6" dual voice coil woofer and a 6" passive radiator. The woofer is powered by a built-in 4-channel Class D amplifier. Two speaker outputs allow you to connect a pair of Fusion MS-BX3020 speakers (or other Fusion speakers) for a full-range system.

Installation Kit: The MS-AB206 comes with all of the power and signal wires you need to install the subwoofer. A harness with 20' of 8-gauge red power wire, 20' of 8-gauge black ground wire, and 20' of 18-gauge blue turn-on lead is supplied, as well as a 19.5' Stereo RCA patch cable. The power/ground/turn-on harness is terminated with a 6-pin Molex connector that plugs directly into the subwoofer's control panel.

Control Panel: On one end of the enclosure is the active subwoofer's control panel. The panel is protected by a cover held in place by two screws. The control panel features the following:

  • Power Receptacle: Female 6-pin Molex connector accepts the plug for the supplied power/ground/turn-on harness.
  • Fuse: A 15A ATO fuse is inserted into the control panel.
  • Input: Recessed Stereo RCA jacks for plugging in the supplied RCA patch cable.
  • Speaker Output: Left and right spring clip speaker terminals for connecting an optional pair of speakers.
  • Auto On Switch: When a remote turn-on lead is unavailable, the Auto On feature will turn on the built-in amplifier when an audio signal is present at the input. When the audio signal is no longer detected, the unit will switch itself off after 90 seconds. The switch should be turned to Off when a turn-on lead is used.
  • LPF: The MS-AB206 has both a fixed and variable low pass filter (LPF). When a pair of MS-BX3020 speakers is connected, the LPF should be switched off (making it fixed at 200Hz). If other Fusion speakers are connected, the LPF should be switched on (making it variable) and the cutoff frequency adjusted between 25Hz and 200Hz using the rotary control.
  • Sub Level: You can adjust the subwoofer's level, relative to the rest of the system, using the rotary level control.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?

Replacement for my previous Fusion Sub that got flooded out when my auto bilge pump switch was not working. This unit is close in physical dimensions compared to the old one to fit in the cargo hold. Really get Darryl's seat bumping. [ Randall  Apr 24, 2018 ]

Q
water resistance Is the unit capable of performing if it gets rained on or is any direct moisture a no-no?
[ Edward  Jun 23, 2018 ]

A
I think it might survive a rain shower that couldn't be avoided but I don't think it's intended for wet applications. I mounted mine under a bench seat in my Parker 21 Sport Cabin so it's pretty well protected. An awesome product.
