Great Purposeful Sub!

I used to gig with just mains and then I recently added the K-Sub. The difference was night & day. Hit the high-pass filters on the mains and your system actually runs louder & cleaner with less strain because the K-Sub will take the "lows" burden off of the mains. The K-Sub is meant for small to medium venues when you just want to really fill the lower spectrum of your sound and not shake the dentures loose off grandpa! The K-Sub give me a tight, punchy bass and made my sound really full. So then picked up the KW 181 when I need earth-shaking bass. Now I have the beauty & the BEAST....the best of both worlds! Great Job QSC!!

Sick

Sounds amazing..easy to transport, easy to set up. Don't worry about crossovers and everything. QSC engineers figured that all out for you.

Sweet Addition To Audio System

Just finishing up a church A/V update project. Decided to add one KSub to round out the sound in the sanctuary of our small church. I dropped by to see how the contractor was doing and he says "listen to this". He played a few tunes off his iPod and I could not believe the difference. The speaker placement is totally out of view on the stage but the sound seems to be coming right from the speaker cluster on the ceiling. I think more than a few parishioners will be scratching their heads trying to fiqure out how that could happen considering we are still using the same original speaker cluster! Great product QSC!

A huge improvement to our sound

The low-end "push" from the KSub, in addition to a pair of K10's made an instant impression on my 9-piece soul band, The Real Deal, and our friends and fans. The shaking on the dance floor proved to be the ultimate test and the KSub passed with flying colors. Now I'm saving my gig $$$ for another! Many thanks to Sweetwater and to QSC !

Amazingly Powerful and Clear

I recently purchased the 18 Inch KW 181 from QSC. I loved the sub, but found that it was more than what I wanted, and the extra bulk didn't make it any easier.

I decided to purchase a K Sub instead, and I'm blown away by the power. Like many people purchasing a sub, I was curious how powerful 2 12 inch speakers would be compared to 18, and I must say I'm impressed.

If you're using this for a full band (drums, bass, etc), I would definitely reccomend purchasing 2 of these subs, to fill in the bass, but I use just one my solo/duo/small band and it's plenty enough power, and the clarity is unmatched. It's powerful but not overpowering if that's make sense :). Another amazing product from QSC.

GOTTA HAVE ONE THESE

I HAVE A PAIR OF K12 SPEAKERS. AND YES YES YES THEY ARE AWSOME. BUT WHEN HOOKED UP TO THIS KSUB IT IS THE ICING ON THE CAKE. IF YOU HAVE A PAIR OF K12'S AND WANT THE BEST SOUND IN THE WORLD THEN FORK OUT THE CABBAGE FOR ONE OF THESE BECAUSE IT ADD'S THAT PERFECT BASS DEPTH THAT IS NEEDED.

working band's dream sub!

The K-Sub is the most compact AND powerful sub I've ever used. My band, 7k, recently used them on a 7-week US Tour and used them in every kind of venue imaginable. We also loaded them in and out of every one of those places! They are truly well-designed, reliable, and sound fantastic. In addition to live vocals and instruments, we also ran full-range loops through them and we never ran out of headroom ... ever! For even more detail, please watch my YouTube videos.

Making 18" subwoofers obsolete dinosaurs?

I have 2 of these (Along with 2 k12 tops) and they are AMAZING. Plenty of low end kick, and in a warm, pulse-your-heart way. They deliver the results needed, and sound fantastic. A 4000 watt system that can cover a large crowd but be moved in and out of a small vehicle by 1 person in about 5 minutes? I remember only 10 years ago it took twice the van, manpower, space and 4x the weight to deliver half the power.

A great specialty product

This isn't a pounding dance club sub. It's a musical and punchy sounding well designed solution to a very specific need: how to fill out your frequencies with a small, portable, relatively light design. If you've got a truck, an assistant and more than 200 guests to entertain, you're probably lugging around at least two 18's. This is not for you. If you're running small solo gigs that need a full sound but not boom, here's your sub. There are smaller less expensive options, but I prefer the extended warranty and reliability of QSC.

One piping hot bowl of deep dish bass!

I own the K12's and added these to complement the setup. WOW does it sound great! I vacillated between the new KW181 as I've seen lots of reviews of people using the K12's & KW181 setup, but decided to go with the Ksub as it's small and fits into my SUV with the rest of my gear.

Because of it's 12" design, I noticed that the bass is really tight as opposed to 15": and 18" designs that tend to be boomier. With the drivers enclosed in the box, it doesn't get as loud as a direct radiating driver (if the power amp was identical), but it's plenty loud all the same.

If size/weight is an issue, I would definitly go with this sub....especially for a tighter, but not as loud sound. If you want to make your chest (and other body parts) vibrate, go with the KW181. Either way, you will not go wrong using QSC!
