Short and simple, This subwoofer is very similar to the Skar ZVX or the Sundown Zv4 but with a T Frame. 10 inch spider, 300+oz ferrite triple stack. Ive owned this sub for 4 months now. Really beat the crap out of it quite a bit. Its very comfortable at 2k RMS. In a 3.6 cubic ft box tuned at 30hz and it hits that tune with authority. Harmony may be a relatively new company with some questionable stuff in the lower price ranges but the Monolith i can say with confidence is a serious sub that will meet all doubts you have of it by beating the back of your skull with low 140's. And i have the 15. Im plenty sure the 18 inch version would put a grin on your face after kicking your ass. ... show more

    • Unbelievable.
Size: 2 Ohm Style: Single Pack
For the cost, these subwoofers are incredible. Also purchased the HA-A1500.1 to drive this beast. In a ported 5 cube box tuned to 32hz it beats my car apart. I think this speaker can definitely compete with some of the big names in car audio.

The media could not be loaded. This ML151 is 57 pounds of loud and low bass. I've got it in a custom box tuned to 32 HZ. I'm still braking this beast in. Honestly I wish it had more peak to peak travel. I've got an old Quantum Audio 3000 watt mono block pushing it. With an XS battery.

    • You will be shocked at the size of this and wonder why someone let you do this.
Size: 2 Ohm Style: Single Pack
update after 2.5 years ... it hasn't let me down at all. Its the last sub that you'll ever have to buy. Hits the lowest notes and is built like a tank with Pennsylvania steel. Show up your friends instead of showing off how much you spent on a sundown or skar.
