crossover breaks the signal into frequency bands which are fed to amps then speakers
so in my rig I have 2 4way xovers feeding one pair CD [constant directivity] horns for the high, one pair 12″ drivers for high mid, one pair 15″ drivers for low mid and one pair of paired 18″ drivers for bass [yes thats 4 18″ drivers for the bottom end] because I use 4 way stereo on the rig. All of my drivers are in radiator cabs
the xovers in question are the behringer ones and when I dont want the bass bins we sometimes use the rig on a 3 way split which is handled by just one xover for the whole rig
make sure you get a good frequency range by making sure your cabs cover the full frequency range [this is done via the specs for the drivers and their thiele small parameters used to design suitable cabs for them]
i also carry a spade at free parties [nothing less attractive than shit everywhere] and below is a packing list I wrote for someone a few years back.
Generator stuff
– the generator [make sure it has the right oil level, that you know how to start it, how to work any power distros it come with it and that it starts before you pack it for the party]
– generator power cables: hire gennies come with various kinds of connections so make sure you have the right plugs to power your rig
– generator earth spike: this is vital IMO and easy to make. It could literally save your life one day so make one and ALWAYS ALWAYS USE IT
– generator fuel- make sure you know what it takes and have asmuch as you will need on hand for the party; also ensure you have the correct containers for storing it
– funnel for filling the genny: you will likely need one so either have one at the ready or learn how to improvise oneTent stuff
– tent poles
– tent connectors
– tent canvas
– spikes for tying it down
– rope for tying it down
– hammer for using with the pegs
– cable ties [big and strong is what we recommend]Rig stuff
– decks and a mixer [vinyl and or cds]
– a table for your decks
– a mixing desk for the rig [we consider this essential as it gives you more detailed control of the sound output]
– amplifiers and speakers and crossovers etc as required by the soundsystem setup
– the cables to connect all of the above – make sure you have them all as it would be real frustrating to get there and find you are one short…
– a light for the decks and maybe another if you are setting up after dark….
– a pallet for the amps [keeps them dry]
– pallets for the speaker stacks
– power distributions to power it all
nothing worse than being short ot 13a plugs
– decorations
– gaffer tape
– ratchet straps for securing the speaker stacks
– monitor amp and speakers
– spare needles for the decksLighting stuff
– stand for lights
– lights or lasers
– dmx controller
– cables to connect the lights
– power distros for lighting equipment
– smoke machine
– smoke machine fluid
Health and safety stuff
{this is the stuff that marks the difference between serious and pretend party crews in my opinion; serious party crews should have it for both their own safety and that of their punters }
– fire extinguishers [powder or CO2] in case of fire in the equipment – 1kg or 2 kg should be ideal for most small rigs
– first aid kit for at least 50 people or as many as you are expecting at the party – venues are ideally pretty darn remote and first aid must be possible
– first aider [preferably with a current certificate but experience counts for a lot – if you dont have one on your crew make a point of asking your punters if any of them would be able to help in an emergency as you dont want to be finding that shit out when someone is bleeding everywhere]
– bin bags bring twice as many as you think you will need or one for every person you are expecting to turn up – some sites need cleaning before the party starts and not having bin liners is a pain
– water containers for crew and punters to drink if they orget water/ run out of it a 25l container is cheap to buy and easy to move – remember to fill it
– spade for burying shit – who wants to stand in that and unburied it can cause serious enviromental pollution – always have a prominently displayed spade for people to use should they forget to bring their own
– midge repellantA vehicle to move it all in
There is an essential equipment list. In addition to that we also carry spares and toolkits for those little disasters which need to fixed during a party. So there are two toolboxes, spare cables, spare connectors, to name but a few
