Deciding on Subwoofers for Dubstep and Drum and Bass
As a concert producer, I am often asked which subs I would recommend. Subwoofers, like mains, are chosen by the kind of music you will be playing even though them, and how they may be going to become used. For the purposes of this article, I am going to restrict the conversation to just Dubstep, and Drum and Bass. Get extra details about 10 inch subwoofer
Dubstep and Drum and Bass have a large quantity of content inside the 20hz – 50hz variety, and for those who do the math, you happen to be going to require about 5000 watts devoted to a that frequency range to produce enough of that sound to be heard along with the rest with the music.
My larger setup is (five) QSC HPR181s across the front in the stage, (six) Martin Blackline dual 18’s for the home, and 2 Bag Finish Dual 18’s running 8000watts by way of an ELF processor dedicated for the 8hz – 50hz variety via a lab gruppen amp. When I play smaller shows, I just use my QSC HPR181, that are 700 watts each and every, but very 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 popular wisdom, don’t mix subwoofers, but in reality, I’ve yet to seek out a single sound manufacturing corporation that does it all, quick of a tour package which is developed for any offered show, in lieu of a form of music (a crucial distinction). That stated, crossover points and maintaining every single subwoofer plus the all round technique in phase is very essential when mixing subs.
Setting the crossover
Standard crossovers, just like the incredibly typical dBx DriveRack PA possess a great and pretty adjustable crossover that also includes the capability to adjust the slope of the roll off. When matching and tuning subwoofer frequencies, I’ve noticed that although the crossover claims to possess rolled a frequency off, a number of the content material continues to become transmitted towards the sub. Clearly, when two brands of subwoofers are creating exactly the same tones, distortion is created. I, consequently, separate the frequencies by about 5hz. Visually around the crossover, it seems that I am losing musical content material, nevertheless, with all the amplification get, the truth is I am not, along with a RTA mic will confirm that the setting are correct.
Sealed box enclosures and subharmonics
Bag Finish is really the go to here. There are other sub systems that do subharmonics, but Bag End was very first, so I’m writing about them. The Infra processor, and just before Ron Wickersham left, the Elf Processor are the two essential components. Dubstep and Drum and Bass demand a massive presence in the 20hz – 50hz range. Most of the people can not hear music in this range, but you can feel it, and also you can really feel the difference amongst 20hz and 40 hz when the signal is clear and free of charge of clipping. The Infra processor is available in two forms. The initial 1 has a flat response down to 18hz, the second one particular to 8hz. 18hz is a lot more efficient for bigger systems. Should you have an added 20k to burn, then go for the 8hz integrator and (4) dual 18’s. You’ll need a substantial volume of AC Energy to run the amps as well, ordinarily an added 20amp 220 circuit for any Lab Gruppen or 4 20amp 110 ciruits for 4 QSC amps bridged into every single sub. My Bag Ends normally pull about 3000 watts per dual 18 when producing content STRICTLY Restricted to the 18hz – 50hz range. I really should note that creating adjustments to your crossover at full volume can quickly destroy all of your equipment, so be careful, and know your equipment frequency response and power handling ratings.
Subs vary tremendously in price. In the lower value variety, I’ve heard the Peavey blackwidows, that are technically louder, but considerably significantly less musical. When you are mashing up two tracks, or promptly transitioning from one particular to another, it really is challenging to hear significantly distinction with all the Peavey subs, they are just loud, not a lot musical. JBL and Cerwin Vega subs are fart cans, and I feel most of the people know this. They can rumble and shake, but they never have an articulated sound – a clarity within the low end that may be completely vital for Dubstep and more so for Drum and Bass.
Some other equipment that I’ve tried, If 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 great all around specs for Dubstep, and Bag End kills. All of these cabinets need extremely expensive amplification though. You are able to get 12,000 into amps alone prior to it is possible to even turn on a mid-sized method of this caliber.
Another alternative, is to build your own box. This is not a beginner project, but if 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 on the forums and look at designs, then read the threads through. Often people post reviews over the course of years.
Look for any design that features a superior frequency response down to 40hz, and a driver that has exceptional frequency response. OHM (brand) makes a pretty incredible driver, and you will find a couple of high end RCF subs that are bad to the bone.
