I agree to an extend. The Corner Positioning is something that i guess is a here nor there aspect but there is no way in hell i would ever turn my sub to face a wall. Here is my reasoning…you may get more dB out of your sub for an overall louder sub…but the wall only reflects certian frequencies…and it will absorb others…now the problem with this is that I like to be able to feel that punch in my chest when im on the dancefloor, and you cannot achive that same punch feeling when 1/2 the frequencies are being absorbed with the wall.

As well another issue you face is that when your sub is at a different distance from your crowd than your speakers you get out of phase. The videos i posted below will give u a general idea of what i am talking about

If you have time i want you to do a little test…Grab your phone turn a song onto it and put it into a Metal or plastic cup. You will notice that the sound will be greatly amplified BUT you will get almost like an echo effect happening. The results are that you get a louder sound at a reduced quality as the sound bounces between the walls of the cup before it is audible to your ears.

sub woofers always need to be in one group. Low frequency sound (bass) spread 360 degree around the speakers and reflection from walls and floor kill direct radiating sound. If you separate sub woofers you add additionally problems because sound from stacks kill each other because is out of phase, you will get comb filtering.

the only flaw in your logic that i can find is that most articles on google regarding sub placement is based on home theater or something of that nature…which is totally different than in a night club…I forgot where i read it but it had said that you want to keep all your sound restricted towards the dance floor. As patrons want to be able to still communicate with each other you want to maximize the sound directly to the dance floor and keep it there oppose to going in every direction.

Most Home Theater setups this is the exact opposite of what you are looking for. Subs are meant more to feel the bass than hear the bass so you want that bass to be non directional that is why you would place it in a corner or near a wall as it would reflect the sub and spread it across the whole listening space.

That is why you will see a lot of the higher end home theater subs with a downfiring speak oppose to front firing…but you will NEVER see a downfire sub in a music setting.

This goes the same for your car sub…as the distance from the wall of ur trunk will reflect the sub bass oppose to facing the seats where the seats will absorb a lot of the bass before you can hear it.

Let me dig around and find this page that i have bookmarked on my home computer…it explains how sound frequencies work and how they interact with each other its really interesting to read and explains things like Noise cancelling, sound dissapation, amplification, resonance, and interaction with objects and matter.

Well I always like to have more than i need because i can always keep my volumes down if need be…The more stress you put onto your equipment the bigger chance that problems can happen in the long run.

As well this is also very dependant on the type of equipment you are using…You can blow your subs if you are using an amp and Speaker system as there is no limiter in the sub. With newer active systems there usually is a built in limiter and the sub will auto shut off if there is a chance you are going to damage your sub.

But I also have to add in that I am a huge believer of Equal sound…proper levels within your sound system as well.

I often see too many times where people just crank their entire system and yeah its loud but it sounds like shit…the highs overpower your lows and you get what i refer to the tin can effect(think of laptop speakers at their max).

I have a buddy that works with PK and his golden rules are:

Create a wall of sound all speakers in a row together
Equal amount of Subs to Speakers…and if need be stack your Speakers
There is never a thing as too much when it comes to speakers…but your show will suck if you dont have enough.
You can make people feel the bass without hearing a damn thing, and ive blown windows to prove it (his words)

Yeah its a bitch when stuff like that happens…I’ve had my Traktor Crash on me once during a gig.

What i do now a days to make sure stuff like this doesnt create problems for my sets are:

I always use a DJ mixer as well as my S4…most of the times i am not the only DJ so there will be 2 cdjs a mixer and my S4.
I always keep a couple of USB sticks around with all my current music as well as my Iphone with my latest pre recorded mix just in case stuff goes wrong…For smaller gigs like bars and what not its not that big of a deal…but when you are playing for 1000+ people and you have the entire dancefloor gripped by their proverbial ballz the last thing u want is your gear to cut out.

I’m happy you were able to just keep going and not make it awkward for your entire dance floor…that is the most important part.

you can still use the sample decks as sample decks with any controller…you just cant use them as Remix Decks

Its not about the gear…its about what you do with it.

Dont get too Gear Hungry, practice on what you have now and master it….master every little button fader and knob on your gear so you are always using them in some form…THEN when you get to a point where you want to do something else and you have created your own direction as to where you want to go THEN invest in something that you want…going up and buying this and that will often leave pieces of your gear collecting dust.

It totally depends on the genre and how my set is built. Sometimes i will just use a 1 min of a track othertimes i will let it play out there is just no set rhyme or way that i mix it all is about the flow of the music. IMO if there is a good flow to the music and the dance floor is bumpin thats all that matters.

I would assume that PN does not compress the song it just amplifies all the frequencies…this is the cause of your distortion.

PN will increase all the Frequencies equally. You would be better off using something like Audacity and use the compressor.

If a song is 100% perfectly mastered then PN will work as all the frequencies are balanced.
