Ladies and gents,
Could someone help me with the backplate on my Ashdown ABM 2x15? ie what all the sockets do?
Many thanks.

Gives you the choice of standard jack plug or the more modern Neutrik speakon type.

Think that's all it is.

They're all inputs, probably wired in parallel. Two jacks and one speakon. They would also act as a link to another cab, although I wouldn't recommend playing with this as your cab is 4 ohm impedance. Most amps have 4 ohms as the minimum impedance they'll work with. Adding another 4 ohm cab (in parallel as it usually is) would take the load down to 2 ohms - not many amps like that.

Cheers guys. I'm happy with the ohmage thing and I was pretty sure that the two jacks were an in and out for a second cab. If I ever do that I'll get one of those series cables and halve my output.

I'm wondering why there are two blacks and two reds going in to the enclosure. Unless there is a separate feed to the tweeter (with no cross-over)

There isn't a tweeter.

One pair of cables for each speaker.

They're wired in parallel at the socket end, presumably to make manufacture a bit quicker and easier.

Not the first time I've been described like that.

To get two speakers in parallel you can either join them together at the speaker end or the socket end.

Joining them at the speaker end in a front loaded cab is more awkward than just gathering the two cables at the backplate and soldering them in one hit.

It also means that you still have a connection to one speaker if one of the cables fails.

Ok thanks guys, stop now, I dipped my 11+ as a kid and my brain hurts I'll have the bugger to bits sometime though!

Hi Mark,

All the connectors on the back of the cab are internally connected together, so you have a choice
of inputs to use..
The speakers are connected in parallel internally so you get a 4 ohm cab..
