for a 300-500 people party 2 k12 and 2 k subs with a behringer ddm4000 mixer and 2 pioneer cdj1000mk3 with mixtrack pro or vms4 controller and mac? is that good?
You guys talking about low freq. extension. Pro Audio subs in general are NOT made for deep extension. They are made for high output from 45-80hz and that's about it. The lowest box tuning freq. you'll typically see is around 38hz for a pro audio sub. This means below that frequency the speaker will be unloaded from the box and a great chance you will damage it with any real power. I suggest at least a 40hz 12db/octave high pass for pro audio subs unless specially designed for extension
@DJJORGEMOJICA have not heard anything good about the Mackie's yet, you have to determine, size, weight, and cost to determine what's best for you....
@DJJORGEMOJICA I Had A Pair Of Mackie SA1521 (The Italian Made Ones) And They Sounded AWESOME But They Both Blew On Me. Try To Stay Away From Mackie Products. My Suggestion?. Try To Find A Used HPR151. 15 Inch Subs Have A Much Tighter, Cleaner, Punchier Bass.
how would you get this thing up and down stairs by yourself....i just bought one and im shitting my pants as to how im gonna get this beast up and down my 7 steps into my house....i mean i know it has wheels but thats not gonna wor for stairs
these fuker actually shakes my neighbors bed. all my living room windows have cracks on them maybe they had hairlines and bb shot cracks but once you put this baby on those small cracks get really big quick. i don't like the shape of it hard to handle with one person and is abt 130 lbs, but i love it and in combo with the k series speakers is a combo hard to beat.
Bagofsucks22: car audio and pro audio are different worlds. you put that type r outside your car and it will have hardly any thump. This qsc 18 is 700w and is designed for indoor or outdoor. you basically need 2 times the watts for outdoor.
SRVjediknight: Getting to 25hz all has to do with tuning the port of the box. Bands dont need low hz, only to about 45hz or so. Which is why they sell it like this. Build custom box to 30hz or lower if needed. This sub is best for the money.
Yes, I have 2 of the SRX718's running in bridge mono using an xti-4000, that's 1600watts per speaker....You happen to know the settings for the crossover in the xti-4000 to match up with the JBL SRX718's?
@mike71flores Settings for the Xti-4000 running a Srx718 are:
Highpass@ 31.5Hz using Butterworth 18dB/Oct
Lowpass@ 80Hz using LinkwizRiley (LR) 24dB/Oct
IMO You can run the lowpass with higher value as well (like 120Hz) to get the desired midbass punch if you top cabs lack the kick. The lowpass freq is more like a tweak and give it a listen type of a thing. Adjust the freq where you like the sound the most. But don't tweak the highpass. It's protecting your drivers when they are pushed hard.
@SRVjediknight JBL srx 718 is a great sub, but doesn't go down to 25hz. 25hz is around the -25dB point which isn't that usable. Only PA subs with real world 25hz performance I can recall are Danley TH-221 (22Hz) and the McCauley M421 (20Hz).. Too bad that both of these cabs are over 400 pounds a piece, so definitely not a sub that a mobile DJ might want to use =D
@SRVjediknight i know this was wrote 1 year ago, but people still read this. i had the jbl's 718 and i got now the 181 qsc sub. and NO, the jbl's don't blow nothing out nowere. SORRY! don't put jbl and qsc in the same sentence please. i'm not saying jbls are junk. by no means, and is true jbls do sound good untill you put a qsc 181 next to them. again people favor what they like so this is my opinion.
hey buddy, nice video...i got a question. Can i hook up this powered sub with two other powered 15 inch QSCs on a regular dj mixer or do i need a mixer such as a mackie dfx of some sort? thanks for your help!
just run your left and right channels to the back of the subwoofer, then take 2 more cables and run to your 15's, left and right. If you notice on the back of the subwoofer you will see 6 different ports 2 are for input from the mixer , other 2 are for ouput to your 15's.
this sub is great, got mines 2 years ago im still paying for this baby, but i would not dj with out my main and only sub, really pro shit here. i had play this thing inside my apartment and my neigbor had told me that her coffe table walks across the floor. is like a roaring thunder. i can't imagine how 2 of these things sound...wow
i have two QSC HPR153i 15" 3-Way Powered Loudspeakers and a B52 18 inch Active X powered subwoofer and that combo has been so great to me djing in clubs and parties...so fucking loud
i am running two 152i's. if i could just afford to buy one of these 181's for right now, how would i hook it up? i am coming out of a rane empath that only has one left and one right xlr out. i currently run one of the 152s on left, and one on right.
Oh, its real easy to do. Just plug your left and right XLR out channels into the back of the SUBWOOFER. Then run cables from the subwoofer to your left and right channels. This means you will need 4 cables
Kyle, I think I know what you are trying to say..but If I have one AMP and 2 speakers and the amp dies...that means 2 speakers gone...With powered speakers and powered sub I have 3 points of failure....if my sub dies my HPR153I's are still strong enough to kick some bass...thanks for your comment though...not to mention they come with a 6 year WARRANTY
im hoping to get one of these very soon, qsc is very respected by the dj community. quality is no#1. my soon to be ex-neighbor is going to help me carry it to my apartment..
I use one sub in the middle......I have had lots of people tell me how great the sound is...very clear...channels are seperated by built in crossovers..
Yea, the wheels make this thing easy to roll , it glides really smooth over bumps and the heavy grill makes it actually easy to carry stuff on it...I know that sounds crazy ...but very nice...
Ahh yes great subs. Heavy yes but very very well constructed. I have never had a problem with the casters vibrating and I pound the lows fairly well. That is the older model you got, the newer ones the gain goes from -30 to 0 db. Otherwise they have the same components. I'm sure you will enjoy it as they are a great sub.
I bought the demo unit for $750 from Guitar Center. It retails at about $1200 ..$100 to ship...I picked mine up locally so had to pay sales tax. Did not plan on buying when I went in the store but took good of deal to pass up.
