Banging heads off the monolith :head_bang…again…:you_crazy:you_crazy:you_crazy..Played right into the hands of anybody who wants all raves to be dealt with by riot police…:you_crazy:you_crazy:you_crazy:you_crazy:you_crazy
Noising up the Police, and injuring the buggers is totally counter productive – they are only there doing their job for the most part…
If the landowner asks you not to do it, what is the point in going ahead regardless – the police have all the powers they need since the CJA (and yeah, I know the CJA sucks, and shouldn’t ever have been made law, but it was, and that’s the world we have to deal with now…)
If you’re doing a party, get permission from the landowner if you can. And if the nick turn up and say you’ve gotta turn it off – do so…Maybe then next time, they’ll be a bit more reasonable.
Another way is to do it right in the middle of nowhere – where there are no people to noise up (if you cannae get your head round the fact that some people don’t want to hear dance music at 20k all night, imagine how you’d feel if 500 country and western fans turned up next to your house, and played Dolly Parton for 2 days solid at 20k – I’d go raj, so I can see why people who don’t like raves do…:crazy::crazy::crazy::crazy:)
And people – can we get rid of the long throw subs on rigs please…They’re stupid, unnecessary, and in totally the wrong configuration for long throws on anything but the most excessive rig (like 50k with full infill etc)
On a rig with no bass fill (radiators to cover the area up to about 35yards), and no mid/high satellites half way down your stadium, set up with delayed phase compensation to aim your long throws at, all you get is no bass next to the rig where people are dancing, but lots of bass in the next field. Or poor farmer Giles 2 miles away cannae sleep cos all he can hear is repetitive bang bang on the wind…:rant::rant::rant::rant::rant:
Build ported radiators (you can easily do a party with 1000 people, using these, and about 4k of active amplification). That way, the jenny needn’t be huge, transporting is relatively easy (meaning if you are asked to leave, you can up and take the party somewhere else:wink:), and less of the general public are noised up.
Really, (and I’m gonna be brutal here cos I’m fed up with the mythology around sound systems) unless you are doing a party for 2,000+ people, you don’t need more than 4k…Anything else is just willy waving about how much juice your rig needs (I can get a good, un-distorted constant 115dB from 4k (actually running at about 3k, but the extra is headroom:biggreen:), with transient peaks up over 145dB. Good quality sound too, that won’t destroy your hearing with distortion (many rigs get this due to overdriving those long throws to try and compensate for the phase mis-match, and the fact that the 1st standing wave of the subs – the point where the fundamental, and harmonic resonances create a node and you can hear the sound properly – is about 12m or so from the rig, assuming perfect phase alignment with the rest of the speakers, and a perfect horn design that can manage to somehow be 4-6m in length – the flare is an exponential curve to maintain the acoustic transformer effect. Reality usually puts it at double that, as phase alignment is a difficult job:crazy:.) And we won’t even go into ‘scoop’ bins, cos I’ll just swear a lot…If you really want to know why not, go here and read:

The H & S regulations (which are relatively ridiculous, as they use the dB scale, with no account taken of acoustic power at different frequencies:you_crazy) say sound amplification should produce no more than a constant 95dB if people are in the presence of it for up to 4 hours, and no more than 140dB peak level. Both of which are more than produced by a 4k rig (I measured it with a dB meter, at 5m. I break those regs, but most of the acoustic volume was bass, which is far less dangerous at high SPL than high/mid)
If you really must have a spectacularly loud rig, go for sympathetic radiators (2 drivers playing exactly the same program material in a single ported box for each speaker). This really does drive the efficiency through the roof…raaa:cloud9::cloud9::cloud9:, but is still only short – medium throw, so has less likelihood of noising up said farmer Giles…:idea::idea::idea::you_crazy:you_crazy)
Anyhow, rant almost over…Just to drum it all in, from the site listed above:
As a result of this widespread pseudo-scientific situation a number of myths continue to circulate. Some are listed below; all are either untrue or only true within certain caveats:
Horn loudspeakers can be relied upon to provide a better bass response than direct-radiating loudspeakers (those whose cones face direct into the room).
Horns radiate with higher efficiencies than direct radiators
A small sealed enclosure (mistakenly called an “infinite baffle”) can produce good bass if it is driven hard enough.
Bass response is better from a loudspeaker in a corner of a room.
There is no directivity at low frequencies, therefore it does not matter where the bass loudspeakers are placed in the room.
How many of these do you subscribe to?

My roof is nice and high, and braced similarly….:bounce_fl:bounce_m::biggreen::biggreen:
The neighbours are gonna wish I’d never found this…..:groucho:
essex police raided this free party nr royston around 9pm last night (sat) smashing equipment,smashing ravers with batons and cs gas.admittedly our actions are illegal but they do not warrant this sort of violence from those who are meant to protect and to serve 
anyway to cut the story,35 arrests were made all equipment seized and numerous police and ravers were injured 
imo it was lucky they didnt start a full on riot,with what the police estimated as 600 ravers which was actully a lot nearer 1000 and rising and probabaly 100+ police(filth) with all the ravers parking up miles away outside the exclusion zone and trekking to the party,if the police had not of raided it,this was on to be a massive party,on land well out of the way and of minimum inconvenience to locals,in short we were only harming ourselves and should of been left alone to do so.in the end a lot of trouble was caused unecessarily and a lot of tax payers money wasted, and more importantly a another nail is hammered in to coffin of the free rave scene
