## Overview

The LD Systems ICOA SUB 18 A is a high-performance powered subwoofer featuring an 18-inch driver, delivering powerful low-end frequencies down to 29 Hz.

## Description

Music starts to really groove when you can feel the bass in your body. The ICOA SUB can deliver as much bass as you want - to get the people rocking and entice them to the dance floor. It can even lend a multimedia presentation that special oomph it needs to reach its audience. The ICOA SUB pumps out serious bass and gives you greater headroom and a clearer sound. This is because your subwoofer relieves the main speaker, whose woofers are now less burdened by high-energy bass impulses, resulting in less intermodulation distortion. Even at higher volumes, the sound doesn't get muffled. Voices and instruments stay crystal clear.

Review: Better Than Expected!! - I did a ton of research before making the decision to purchase the LD Systems Icoa 18a subwoofer. Iplay in a variety cover band and we need to have solid low freq to drive the bottom end for the dance floor. This does the job very well by itself! I would love to have two of these, but just don’t have room in my vehicle for a second one. I have played with the gain levels and kept a close eye out for peaking, but did not get there even at incredibly high volumes. I was astonished by the clean low end this sub gets down to! 29Hz! And you can definitely hear it. The sub is an absolute must if you want clean deep bass for low-freq reinforcement for your band or DJ rig. Thanks to LD Systems for creating such a fine subwoofer!
Review: It's not what everyone says that it is. - Our of the box it had some damage, the box was clean. The paint is cheap and it makes a little rattle when is playing. I put them next to my Yorkvilles and they they just can't compete. My Yorkvilles sound 2.5 louder than the LD. I paid over a thousand dollars and they just can't compete. They sound the same as the $400 Rockville. So disappointed. For that price get something else. The original cover for it is so big that the speaker is swimming in there. Another negative is that it doesn't come with weals.

### ⭐⭐⭐⭐⭐ Excellent low end!
*by J***S on May 18, 2024*

I have two and the cardioid mode is terrific! It makes it extra loud in front of the subs, but kills the bass behind the subs, making it not so punishing to be behind them. They are big and heavy, but they are so worth the money!
