wiring horn into small cabinet

[ceilidhswinger]

Ive just recently bought an Ashdown Little Giant that I plan to use with a 1200w cabinet (the kind boy racers use in their cars and they go boom! boom! boom!) which I bought for sweeties at a car boot sale. I think I will need to add a tweeter to cab as a bit too heavy on the bass side. If it works, it will be a fine small space saver set-up for long haul gigs and might double up for double bass? All I need is a wiring diagram, anybody out there know how to add a horn to a cabinet or should I get a pro to do it?

Cheers Straight six, will have a look at link, my mates got an old high powered horn from his keyboard amp, will hook it up externally first. I will have to check Ohms and stuff I suppose, dont want to blow new amp.

That depends on the type of horn you decide to use.

If you are looking at piezo types then they are treated as not having an impedance.

If you are looking at the more expensive compression driver types then those do have an impedance and will also need a proper crossover

Thanks for your reply icastle, I will get a look at my mates at the weekend. Am I right in saying that compression type are like little sealed units or land mines? little stubby things!

Well I generally work on the principle that if it's light and made of plastic it's a piezo but the landmine description of the compression type works for me...

Mmm! got me thinking now, picked up hornfrom mate tonight, it was in his Behringer amp hooked up to 15 inch 4ohm spkr, horn rated at 40w 8ohm , screw on plastic horn which looks like land mine or magnet, will hook up and test at the weekend.

Forgot to say, I also disconnected a pcb which speaker and horn were connected to,pcb had resistor and capasitor on board, I will connect dry and see if it all works,

You're going to need that PCB...

Hooked it all up this morning and very low output volume wise. Gonna get a man that know what he's doing to have a look.
