Oh lord
Best speakers ever, give 100000 points
Ks118
All that waiting is finally finish, can't ask for nothing better ks118 is powerful bass, love it
Music background: Djkid
Probably the best sub in the world.
I had the bose f1 subwoofer but when I discovered this subwoofer right here I was interested, I really wondered if this thing can blow the bose sub away, I heard a demo on the ks118 sub at guitar center and I wasn't actually in shock like I felt the bose f1 sub was about with it, but when the live sound employee put on a dubstep song and felt that bass hit I was like woah!!! Holy crap! I was tooken away, I needed this sub, I sold my bose f1 subwoofer saved up for this one and I'm more than happy with this sub, it has extreme output and sounds phenomenal, the bose f1 subwoofer is a phenomenal unit too, but only can go low to a certain extent just like the ks118, but the ks118 goes lower sounds better and goes a lot louder its really a shocker.. I've heard of the Yamaha dxs18xlf subwoofer too, I looked into that one too, but I went with this one, I'm pretty sure it's as good as this one or not as good, I don't see any single 18 going louder than this one can do, seriously.. or sound as good as this one at high levels, the ks118 looks rugged clean, very professional looking, and powerful looking, the Yamaha dxs18xlf is ugly looking no offense Yamaha haha..

Holly was more than helpful and accommodated all of my needs. First time purchasing through Sweetwater and will definitely purchase more of my live audio from here. Cant wait to test out these KS118's, I've heard them live before and they sound great!

Kicked but and very pleased!
We used our New K118 pair for the first time on a small EDM show for about a 100 people. I was pretty nervous that they would not be enough, however, not only did they keep up but they did kick but! The crowd was very happy and got tons of compliments.
i did put a high pass filter to about 30HZ and had the subs on deep. Helped keep them punchy and prevented any clipping.
