As a concert producer, I'm often asked which subs I would propose. Subwoofers, like mains, are selected by the kind of music you will be playing though them, and how they are going to become made use of. For the purposes of this short article, I am going to restrict the conversation to just Dubstep, and Drum and Bass. Get much more information about Click here
Dubstep and Drum and Bass possess a substantial amount of content within the 20hz - 50hz range, and if you do the math, you happen to be going to will need about 5000 watts committed to a that frequency range to generate sufficient of that sound to become heard as well as the rest from the music.
My larger setup is (5) QSC HPR181s across the front in the stage, (6) Martin Blackline dual 18's for the home, and two Bag End Dual 18's operating 8000watts via an ELF processor dedicated towards the 8hz - 50hz range by means of a lab gruppen amp. When I play smaller sized shows, I just use my QSC HPR181, that are 700 watts each and every, but good for ultra high volume bass. The QSC's are self powered and take all of five minutes to setup, which also assists. Now I've heard the frequent wisdom, don't mix subwoofers, but in reality, I've however to locate one particular sound manufacturing business that does it all, short of a tour package that is produced for any offered show, instead of a sort of music (an important distinction). That said, crossover points and maintaining each and every subwoofer plus the overall technique in phase is very crucial when mixing subs.
Setting the crossover
Traditional crossovers, just like the really frequent dBx DriveRack PA possess a superior and fairly adjustable crossover that also contains the potential to change the slope in the roll off. When matching and tuning subwoofer frequencies, I've noticed that though the crossover claims to have rolled a frequency off, a few of the content material continues to become transmitted to the sub. Clearly, when two brands of subwoofers are creating precisely the same tones, distortion is created. I, hence, separate the frequencies by about 5hz. Visually around the crossover, it seems that I am losing musical content material, having said that, together with the amplification gain, the truth is I am not, as well as a RTA mic will confirm that the setting are correct.
Sealed box enclosures and subharmonics
Bag End is really the go to here. There are other sub systems that do subharmonics, but Bag Finish was initial, so I am writing about them. The Infra processor, and prior to Ron Wickersham left, the Elf Processor will be the two crucial elements. Dubstep and Drum and Bass need a huge presence inside the 20hz - 50hz range. Many people cannot hear music in this variety, but you could feel it, and also you can really feel the difference among 20hz and 40 hz when the signal is clear and cost-free of clipping. The Infra processor is available in two forms. The first a single includes a flat response down to 18hz, the second a single to 8hz. 18hz is a lot more efficient for bigger systems. Should you have an further 20k to burn, then go for the 8hz integrator and (4) dual 18's. You'll need a substantial level of AC Power to run the amps at the same time, normally an additional 20amp 220 circuit for a Lab Gruppen or four 20amp 110 ciruits for four QSC amps bridged into each sub. My Bag Ends usually pull about 3000 watts per dual 18 when creating content material STRICTLY Restricted to the 18hz - 50hz range. I ought to note that producing adjustments for your crossover at full volume can speedily destroy all your gear, so be careful, and know your gear frequency response and power handling ratings.
Subs vary tremendously in price tag. In the reduced cost range, I have heard the Peavey blackwidows, which are technically louder, but considerably much less musical. When you're mashing up two tracks, or rapidly transitioning from one particular to a different, it is tough to hear substantially difference with the Peavey subs, they are just loud, not a lot musical. JBL and Cerwin Vega subs are fart cans, and I consider a lot of people know this. They could rumble and shake, however they never have an articulated sound - a clarity in the low end that's absolutely required for Dubstep and much more so for Drum and Bass.
Some other equipment that I've tried, When you are wealthy, the D&B (not db technologies) audioteknic Q2 subs are killer, EAW 218z subs are pretty great, McCauley does a pretty decent sub with good all around specs for Dubstep, and Bag Finish kills. All of these cabinets call for extremely expensive amplification though. You may get 12,000 into amps alone before you'll be able to even turn on a mid-sized technique of this caliber.
An additional alternative, is to build your own box. This is not a beginner project, but when you love wood working, and possess a spare 2500 bucks, you are able to build some pretty amazing cabinets. The best way to do this is to get around the forums and look at designs, then read the threads by way of. Often people post reviews over the course of years.
Look to get a design that has a excellent frequency response down to 40hz, and also a driver that has exceptional frequency response. OHM (brand) makes a pretty incredible driver, and you can find a couple of higher end RCF subs that are bad towards the bone.
