2-way PA cabinet wiring - help needed

[Tom Watkin]

Hi guys, new here, been looking around and it seems like a great community!

Anyway, down to business:

Ok so i'm currently attempting to build a 3-way PA system, and my top pair of speakers are going to be twin 15" Eminence beta 15a's (300W each) with 100W 2" compression drivers.

I have a digital crossover and NL4 sockets and plugs. My question is, whats the best way to wire them inside the cabinet and power them both?

Basically i'm not sure how to wire the 1+ 1- 2+ 2- to the drivers.

Any help would be much appreciated.

Cheers,

Tom

Same as all other interconnects.
Twisted pairs for every Flow and Return.

Hi, it's up to you to decide if the 1s or 2s will be the Mids or the HF.

I presume the 15s are 8 Ohms each & will we wired in parallel ?

For eg,

Both 15s + to 1+ * Both 15s - to 1-

HF + to 2+ * HF - to 2-

Hi guys, thanks for the reply. I forgot to mention if it's not already obvious, I will be bi amping the cabinets. So the 15"'a and the 2" comps will have different amps.

Will this effect the wiring?


So far I'm going to wire the 2" comp to 1 nl4 connector 1+ and 1-
But the 15" drivers will be in parallel yes, so is it not just a case of sending the power from 1+ and 1- to both of them, or sending power to one from 1+ and 1- and the other 2+ and 2-?
