Overview

The QSC KSub Powered Subwoofer is the ideal supplement to QSC K Series 2-way speakers for live reinforcement of bass instruments and drums, or higher-level playback of recorded music. Its 1000W Class-D power module never fails to deliver. The KSub subwoofer's M20 threaded pole socket (pole included) provides a secure, wobble-free method of elevating a mid-high speaker over the subwoofer. The KSub subwoofer's compact footprint won't take over the stage, dance floor, or seating area of smaller venues. A pair of high-power 12" speakers in an optimized band-pass enclosure will handle everything the 1,000-watt power module can give them. Compact in size, the QSC KSub has ergonomically designed handles and 3" noise-free casters ease load-in and load-out.

1000 Watts is really loud. The bass from the KSUB sounds smooth and clear, with deep solid chest thumping hits. The dual 12" speakers inside really are amazing in how QSC managed to produce the powerful bass this sub gives. I bought this KSUB new from my local GC and in the pictures the casters are silver, but the cab i bought had BLK casters and they didn't rattle either when i tested the sub. I went straight home and set it up and was amazed. 18 inch subs produce a low frequency of 30 Hz, and this sub produces as low as 44 Hz. But 12's are punchier than 18's. The payoff for me in this sub is the full sounding bass of the KSUB and that it's light enough for me to lift and load alone. If you get an 18 in favor of a deeper 30 Hz bass, you'll definitely sacrifice the lightness and need a second person to help you lift it. PROS: It's very light (72 lbs.), it's compact, it sounds great, looks very professional, quality craftsmanship. I'm 100% satisfied. CONS: seriously no downside to this sub.

I bought one of these subs along with two k12's from my local guitar center. My overal first impressions of this sub was that it sounded good but didn't really have the output or the bottom end that I was expecting. So I bought another. 2 ksubs with the k12's mounted on top sounded great. I have used these for both DJ gigs and running sound for my Dad's band. After having these for about 6 months I finally decided that I wanted more and sold both of them and bought a KW181. Big difference. I can't wait to get another. The ksub's just simply don't have that impact that I was looking for. If your looking for chest thumping bass and you like QSC buy a KW181.

The real deal.

By Crabfat Slim

from Westminster, MD

Comments about QSC KSub Powered Subwoofer:

This is what I expect to be the final PA purchase (other than a 2nd K-Sub) for my band. (7 Piece R&B, Blues. I was origionally looking for 2 passive Mains and Subs but considering I did not need power amps and the light weight and the awesome clean punchy sound thsi was the way to go. I will use our PA amp (Yamaha 512) to power the floor monitors.

Chest thumping bass

By Good Time Entertainment

from Middletown CT.

Comments about QSC KSub Powered Subwoofer:

Great sounding Bass, very crisp, clean and loud. I am a mobile DJ so size and weight is a big factor for me and this sub fit the bill. Before I bought this I was running the B52 Matrix 1000, so I'll compare it to that. The Matrix with a 15" 400 watt sub puts out deeper bass which is great for hip hop but it distorts when turned up loud plus the Matrix weighs 120lbs. The QSC gets much louder and still sounds great, like I said crisp, clean, chest thumping and the QSC is much easier to handle at 72lbs. and about half the size. Overall I am very happy with this sub...QSC says they're passionate about sound and from what I hear they mean it.

Super Portable "one tone" Bass

By FOHtonefreak

from Chicago, IL

Comments about QSC KSub Powered Subwoofer:

If you are interested in portability alone, these are an excellent choice. If you care about sound quality AT ALL, please go demo these. I played a variety of music (I'm an experience FOH tech) and couldn't hear more than just some rumble. I did not hear the bass NOTES. The in store sales people agreed that they did not sound musical at all at ANY volume. Use your ears and stay clear. If you need recommendations, ask or check a pro audio forum.

Clean portable bass for almost all applications!

By Cris

from Algonquin, Il

Comments about QSC KSub Powered Subwoofer:

i have 2 Ksubs and these things rock! I have found that subwoofer placement is the key to getting big bass out of these things. I rarely use both, I just did a party for 180 people and 1 Ksub had enough to knock off some liquor bottles from the bar shelf! I find having the subs facing a wall or even better a corner really amplifies the output. And since they are super portable and low key, it helps them keep out of sight. I can have the sub 10 to 20 ft away from me and the whole room gets filled with loud clean bass! When using the pair, i couple them together side by side and the output is amazing. They work well for dance and hip hop music, which is what I mostly play. Only a few songs with the lowest of frequency I notice the limitations of a 12" woofer. But really that's only about 5% of the music out there. I feel the pair of Ksubs is louder than my previous PRX718 sub but just don't go as low. The build quality is excellent so no worries there. You' ll pay a pretty penny for them, but for me portabilty and flexability were key. When I had 1 PRX sub, sometimes it was too much to bring for parties with 100 people or so, now I have option to bring 1 sub, and with the pair 350-400 people is no problem.

Ksub is a winner

By Shawn Beckner

from Charleston, SC

Comments about QSC KSub Powered Subwoofer:

To those of you dissuaded by a couple of the negative reviews...please ignore them. I have a pair of K12's on top of two Ksubs...will soon be getting two K10's to use as floor wedges. We are a four piece wedding/corporate event band....and this set-up helped get us bigger money, many more referrals and better gigs in general. In fact, since purchasing all of this QSC gear we've also landed a booking agent and have already paid everything off plus some...only a couple months later. I'm not joking...I was surprised at the difference it made all around. It's an investment you only have to make once (6 year warranty!) Seriously professional quality sound...like a hi-fi home audio system only ON STAGE!!! I would rather bring my system to almost any venue than use the house system. The bass thumps (I'm also the bassist) and the kick drum kicks. When we play bumper music before or between sets it's funky and clear. Truthfully, it's a very balanced little system...and tear down and transportation is a snap. We get compliments about our sound, and it's just so clear that even at higher volume nobody is running for the doors...hard to explain, but it's a pleasant effect...the sound from this rig is just so clear. If you are a DJ playing blast beats down in the -35hz range, then maybe you should look into carrying around 4 18inch subs and a couple tops...but that's not our gig. We're a funky dance band and this system seems to have been specifically designed for our use.

QSC KSUB

By Ken F.

from Brnachburg, NJ

Comments about QSC KSub Powered Subwoofer:

I recently upgraded to all new QSC K series, from Behringer B215A (yes a huge upgrade). Everything about QSC is better. You get what you pay for in the speaker market. Everything now is super clear, and bass from the K12 is surprisingly good (down to 47-48hz). If you need lower bass, you can get one or two of the Ksubs. The only reason I gave it 4 stars was because of the lack of SUB-Bass. This cabinet only gets down to 44 Hz, which does not really cut it for high output bass dance, club and, hip-hop music. If you want warm punchy bass, this is fine, but for larger venues, you will need the 18" tranducer. I am deciding between the JBL EON 518, PRX 618S, 618SXLF, and the QSC KW 118. All of those produce frequencies lower than 44 Hz, which provide sub-bass I need. Now, this thing is SUPER PORTABLE, and sounds fantastic, but does not go low enough for me. A great unit, but I just prefer larger sized tranducers as opposed to the dual 12" transducers, especially for subwoofers. QSC is seriously stepping up in the audio world.

bought this sub a few days after doing weeks of research. Picked this sub over the JBL's and glad I did! I dj house and dubstep music and the precision bass is what I needed! I dj last night and the bass was amazing and powerful! People were coming up to me and said they heard my music a few blocks away! Truly amazing sub!!!!

NO MORE HEAVY SUBS!!!!!

By Josh E.

from Slidell, LA

Comments about QSC KSub Powered Subwoofer:

To the review above giving it two starts; Sir I have no idea what you are hearing or what your definition of a sub should be but last time I checked subs do one thing and that is provide a deep amount of low end to compliment the music. I own this sub and was skeptical at first but after hearing it I was pleasantly surprised because now not only is it more portable it provides WAY better tone than any 18 ever could. The bass "Notes" are tighter thanks to the two 12's and not so sustained when playing any music. I love this sub and the only complaint that I have is that I don�ۡ���t own two of them, but if you don�ۡ���t like yours I would gladly take the KSub off your hands. QSC knocked a home run with this sub. For the mobile DJ, you can do better than this.

NOT for Hip Hop/Electro/Reggae DJ's GREAT for bands/musicians

By DJ Rhythmic

from Los Angeles, CA

Comments about QSC KSub Powered Subwoofer:

QSC is and amazing company with excellent Pro Audio gear. The KSUB is a fantastic piece of equipment... IF... you're a band/musician playing small, indoor venues and would like to add some low end to your sound. I own a number of Yamaha DSR 15's and the matching 18" subs. I'm resident DJ at Havana House Whittier, a small indoor venue, and take my own sound. I got the KSUB hoping to leave it there so I wouldn't have to lug so much gear in every Saturday. Unfortunately, It puts out as much low end as one of my DSR 15's (I use three at H.H.). I gave it 3 stars 'cause it should've been advertised a little differently. It would've been helpful if G.C. & QSC would've marketed the KSUB to bands/musicians as it would be MORE than enough low end. If you're a DJ or play Electronic music and need your frequency range to go lower than say... and kick drum... then the KSUB is NOT for you. If you're willing to spend the cash and need reliable speakers that put out great sub base indoors and out... go with an 18" sub made by QSC, Yamaha, JBL, Yorkville or Turbosound!

Awesome product

By Tim Simmons

from Woodland, CA

Comments about QSC KSub Powered Subwoofer:

I started out with just QSC K12's then purchased two QSC KW181's and while I love the thump, I wanted to go smaller and add to my list of QSC Speakers. So I purchased two QSC K8's and the KSub. My first gig was last Friday night and I was amazed at how well the sound filled the room. I do use a DBX DriveRack PX Powered Speaker Optimizer and I love it, simple one man operation that allows me to setup quickly and for A local hall that I work several times a year and it all fits in the Prius! I will get one more, just because I like the look of mounting the mains on top, but what an awesome sounding sub!

No chest thumbing sound from ksubs

By SHANTANU

from Franklin,TN

Comments about QSC KSub Powered Subwoofer:

I have purchased two K12 and two ksubs in order to get chest thumping experience what some reviewer wrote here. All those speakers are connected to a brand new Allen & Heath Zed 12fx mixer. Now, I tried to play music with lots of drums in it from my iPad which is connected to mixer line with a 1/8 inch cord. I am not experiencing any special sound boom or nice bass out of KSUB. Those are just two big rocks for me. I called QSC but their tech support was useless and half of the time I had to repeat what I am saying. He definitely doesn't speak or understand English well. totally frustrated at this point. I am seriously considering to return these expensive KSUB rocks. Customer service lady Krista at Guitar Center, Cool Spring,TN was excellent.

Comments about QSC KSub Powered Subwoofer:

i purchased this sub at GC and paired it with two K12's. The sound is fantastic. Punchy bass from the ksub and the K12's cover the highs very clearly. The Ksub is extremely mobile, the casters on the bottom are very high quality. I have received many compliments on this setup. Great job QSC!

I just wanted to i lovee this sub it's the best in my opinon it's like the apple ipod the price never change that much that's how you know it's the best.The reason i love this sub is b/c it looks simple and small, but don't thnik it wont throw down this thing will bring it,The bass i very nice for it's size and it's light compared to other subs that look big, that's why i love the ksub.But to rap it all up i think anyone that love bass or the is a Dj should get this b/c QSC is the best.

By Nick Whitaker

from pgh pa

Comments about QSC KSub Powered Subwoofer:

i rented one of these for a live show i was putting on. We had a VFW with about 200people. This sub did not impress me, it has bass to rumble your chest, but no tone what so ever. We used this sub for kick drum, which was not that loud, and for bass drops (sample pad) All the mixes were ran through a mixer and compressor and crossover, and the sub still didnt have that punch that i usually get from my Yamaha Club Series 18in subs

Beware. Not made for kick drum and bass guitar.

By curt beasley

from central Florida

Comments about QSC KSub Powered Subwoofer:

I had a Harbinger powered sub that sounded killer for my band's live sound. I sold it and bought a Ksub because it weighed so much less. Worst mistake of my life. This speaker does not do live sound. When I play my ipod on breaks it sounds great but it simple does not reproduce live sound the way a front firing 18" speaker does. If I was a DJ, this would be the only sub I ever owned. I can easily load and unload it by myself and its plenty loud.
