Monoprice Monolith Dual 15” M-215 Overview

So let’s get into the nitty-gritty. Cards on the table, this is a monster of a sub. It measures 28” x 20” x 42” (L x W x H) and weighs in at a whopping 216 lbs. You read that right! The Monoprice Monolith Dual 15” M-215 THX Ultra subwoofer uses HDF in its construction. While that means it’s heavy, it’s also very well-braced and ready for whatever you can throw at it. 

Monoprice has dual 15” drivers powered by a 2000w (3600w peak) amplifier with a frequency response from 14Hz-200Hz in extended mode and 16Hz to 200Hz in THX mode. The Monoprice Monolith Dual 15” M-215 THX Ultra subwoofer has a single slotted port at the bottom that can be closed with an included foam port plug

Around the back are a trio of knobs for crossover, phase, and level. There are also switches for crossover on/off, EQ, and auto on/off. Monoprice has provided some options for connections with unbalanced RCA and balanced XLR input/output. 

Our Take 

The Monoprice Monolith Dual 15” M-215 THX Ultra is a beast of a sub. And this is an excellent price if you are in the market for a high-performing subwoofer with a reasonably small footprint. 

Sure, you will have to bribe a few of your buddies into helping you move it and probably reinforce your floor. But once you feel that boom rattle your teeth and your house, it will be worth it! 

And I think you all know how much I love my Monoprice Monolith M-10 V2. That has more than enough boom for my space. I couldn’t imagine having even more! But if you need and want it, the Monoprice Monolith Dual 15” M-215 THX Ultra is the subwoofer for you!
