Diagram for a speakon series box

[Delberthot]

OK guys and gals. I know that this has been asked before but I'll be damned if I can find the thread about it.

Something like two 4 ohm speakers run in parallel will give a total load of 8ohms I think.

How would I then go about connecting 2 4ohm cabs to my amp so that the total load is 8ohms - special lead, box of tricks, work of the devil?

I think I've found the answer already - a series lead which will give me 320w @ 8 ohms total

Alternatively, I may look into getting a power amp to power the other cab. We'll see

In parallel it will be 2ohms, in series 8ohms

[Delberthot]

I knew it was one or the other

So did I.

And to wire two cabs together in series you will generally need a bespoke lead or two - things are generally set up to work in parallel.

So for my next question - does anyone have a simple, easy to read diagram so that I can build myself such a box?

I was thinking about a box with 6" of cable coming out of it terminating in a speakon plug to connect to the amp with 2 speakon sockets at the other end

I have seen them but they're expensive and I want cheap.

Sorry to hijack but could the same could be done with 2 8ohm speakers bringing them down to 16ohms?… and is it possible to run 2 lots of those normally bringing it back to eight?

[Delberthot]

Yes. Each amp output could have a series box connected to two eight ohm cabs giving 16 ohms. do that twice and your amp will see two 16ohm loads which will make it see 8ohms

That should be a doddle to build. Unfortunately I've not wired a speakon connector, so I can't advise how to wire these up. To be honest, rather than having an integral cable, I'd probably build the box with three connectors - one to amp, and two to speakers.

Al Healey was kind enough to PM me a link to this diagram




I've never wired a speakon before so don't know how this would translate to that from 1.4" jacks

Standard speakons just have a sleeve and tip the same as a jack so the only difference is the picture!

It's a 5 minute soldering job. 3 mono jack sockets from Maplins and a £2 mini plastic enclosure. Edited June 26, 2011 by Al Heeley
