Picking Subwoofers for Dubstep and Drum and Bass
As a concert producer, I'm frequently asked which subs I'd suggest. Subwoofers, like mains, are selected by the kind of music you will be playing even though them, and how they're going to be applied. For the purposes of this article, I'm going to restrict the conversation to just Dubstep, and Drum and Bass. Get far more details about 10 inch subwoofer
Dubstep and Drum and Bass have a massive level of content in the 20hz - 50hz range, and when you do the math, you might be going to will need about 5000 watts devoted to a that frequency variety to generate sufficient of that sound to become heard in addition to the rest of the music.
My larger setup is (5) QSC HPR181s across the front with the stage, (6) Martin Blackline dual 18's for the house, and two Bag End Dual 18's running 8000watts via an ELF processor committed to the 8hz - 50hz variety by way of a lab gruppen amp. When I play smaller sized shows, I just use my QSC HPR181, which are 700 watts each, but superior for ultra higher volume bass. The QSC's are self powered and take all of 5 minutes to setup, which also aids. Now I've heard the popular wisdom, don't mix subwoofers, but in reality, I've yet to find one particular sound manufacturing company that does it all, brief of a tour package that's created to get a offered show, as opposed to a form of music (a vital distinction). That mentioned, crossover points and maintaining each and every subwoofer plus the overall method in phase is very important when mixing subs.
Setting the crossover
Traditional crossovers, just like the pretty widespread dBx DriveRack PA have a great and pretty adjustable crossover that also consists of the potential to change the slope from the roll off. When matching and tuning subwoofer frequencies, I've noticed that while the crossover claims to possess rolled a frequency off, several of the content continues to become transmitted towards the sub. Clearly, when two brands of subwoofers are producing precisely the same tones, distortion is made. I, hence, separate the frequencies by about 5hz. Visually on the crossover, it seems that I am losing musical content material, on the other hand, with the amplification acquire, in reality I'm not, along with a RTA mic will confirm that the setting are right.
Sealed box enclosures and subharmonics
Bag End is actually the visit right here. You'll find other sub systems that do subharmonics, but Bag Finish was initial, so I am writing about them. The Infra processor, and before Ron Wickersham left, the Elf Processor would be the two important components. Dubstep and Drum and Bass need an enormous presence inside the 20hz - 50hz range. A lot of people can not hear music within this variety, but you'll be able to really feel it, and you can feel the distinction involving 20hz and 40 hz when the signal is clear and cost-free of clipping. The Infra processor is available in two types. The very first a single features a flat response down to 18hz, the second one to 8hz. 18hz is a lot more efficient for bigger systems. When you have an added 20k to burn, then go for the 8hz integrator and (4) dual 18's. You will need a substantial quantity of AC Energy to run the amps too, generally an extra 20amp 220 circuit for a Lab Gruppen or 4 20amp 110 ciruits for four QSC amps bridged into each sub. My Bag Ends typically pull about 3000 watts per dual 18 when producing content material STRICTLY Limited towards the 18hz - 50hz range. I ought to note that creating adjustments to your crossover at full volume can speedily destroy all of your equipment, so be careful, and know your equipment frequency response and energy handling ratings.
Subs differ tremendously in price tag. Within the reduce value range, I have heard the Peavey blackwidows, that are technically louder, but significantly significantly less musical. When you're mashing up two tracks, or promptly transitioning from one particular to another, it truly is challenging to hear a lot distinction together with the Peavey subs, they're just loud, not so much musical. JBL and Cerwin Vega subs are fart cans, and I think the majority of people know this. They're able to rumble and shake, however they don't have an articulated sound - a clarity inside the low end that's definitely important for Dubstep and more so for Drum and Bass.
Some other gear that I've tried, When you are wealthy, the D&B (not db technologies) audioteknic Q2 subs are killer, EAW 218z subs are pretty very good, McCauley does a pretty decent sub with good all around specs for Dubstep, and Bag End kills. All of these cabinets demand extremely expensive amplification even though. You'll be able to get 12,000 into amps alone ahead of you can even turn on a mid-sized program of this caliber.
A different alternative, is to build your own box. This is not a beginner project, but in case you love wood working, and have a spare 2500 bucks, you are able to build some pretty amazing cabinets. The best way to do this is to get on the forums and look at designs, then read the threads by way of. Often people post reviews over the course of years.
Look for a design that includes a good frequency response down to 40hz, as well as a driver that has exceptional frequency response. OHM (brand) makes a pretty incredible driver, and you can find a couple of high finish RCF subs that are bad towards the bone.
