Mackie SRM1850 overview

  • 1Description

The Mackie SRM1850 1600W 18" Powered Subwoofer is for extending the low-frequencies in a sound system. It is used in various environments for sound reinforcement applications such as portable DJ's, live stage, houses of worship, theater, rehearsals and more. It features 1600W of power and has an 18" subwoofer. The subwoofer is enclosed in a front ported internally-braced all-wooden cabinet and delivers maximum low-frequency extension and punch. It is built to provide tour level road-worthiness.

The SRM1850 subwoofer features stereo XLR inputs, full-range and high-pass outputs, and a variable digital crossover that includes presets for the SRM550 and SRM650 loudspeakers (sold separately). It features a Smart Protect DSP that protects the subwoofer from overloads if things get pushed a little too hard. The driver has its own compression circuit which helps protect it from damaging transient peaks. This compressor is designed to be transparent and is not noticeable under normal operating conditions. An AC power cord is included.

Note: The SRM1850 18" powered subwoofer is designed to sit on the floor or stage. It is not designed to be pole-mounted or suspended. The cabinet has no rigging points and is not suitable for rigging. Never attempt to suspend the subwoofer by its handles.

    Mackie SRM1850 reviews

    SRM1850 1600W 18" Powered Subwoofer is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from I have bought 2 and cannot be happier ! I've spent a lot of time doing research as to build a perfect active sound system, at least for my preference. This sub is flawless, powerful & true to it's name (built like a tank). The Mackie SRM 1850 has been said to be perfect for the srm 350 & srm 450. That's not true! However, they are set up perfectly for the Mackie SRM 550 & Mackie SRM 650. The panel indicator on the back specifically has a crossover switch for the 550, 650 & variable, which allows the option to use variable set of speakers like the 350's & 450's as well as others for top monitors. (SRM 150,350 & 450) vs (SRM 550, 650, 750 are the professional set & are HD). Smooth, Thunderous & Solid piece of work. The big brother of this line is the Mackie SRM 2850 (double 18) and has a crossover panel that supports the SRM 650, SRM 750 & variable.

    Rated 4 out of 5 by from Great Price Great Product As a Dj its very important to have subwoofers for any gig, this product is perfect match for me as i use Mackie srm 450's which goes with this subwoofer.I am happy with the fact that its lightweight and compact.Also i am very happy with the sound.i think the thump of bass should be little more compare to 600w..

    Rated 5 out of 5 by from Yes, these subs are awesome! I bought 2 Mackie 15's and 2 18's Thumps of them to replace my old Berhinger 800 watt satellites and subs. The Mackies weigh less, are loud and clear with fantastic range.
