hi folks, just picked up a matching 1x15 to go with my rumble combo. The guy I bought it from said that I should use a jack to speakon lead to connect them up.
the combo only has a jack out and the cab has either a jack or speakon connection. I've been trying it out with just an ordinary jack to jack speaker cable and all seems fine. I can't find any info out there about this specific jack to speakon connection but there is mention of a live wire connection between combo & cab.
should I be cautious here? I don't really understand this live wire connection thing. It's sounding very nice but I don't want to blow anything up!

You can get away with using a normal guitar cable at low volumes (home practice level), but it’s risky as the volume goes up.
But I’ll go back and edit my post to clarify what I mean by “low volumes”.
The only real reasons to use Speakons are if the current is too high for 1/4" connectors (in theory anything over 6A*, but in practice many companies get away with more) or if you're worried about the plug coming out. Or just to distinguish it from an instrument cable, but a speaker cable should be short and fat anyway, so fairly easy to tell apart.
There is no "live wire connection" between the amp and the cab.
(*6A is equivalent to 288W into an 8-ohm load, or 144W into 4 ohms - continuous or average power, so if it's a musical signal you can get away with at least double that.

(I’m speaking from direct experience - this happened to me last weekend. In fact I’ve just bought a new speaker cable to give to that guy to try to ensure he stops using a guitar cable).
Please go back and read my first post, the one that says “it should be a proper speaker cable” and realise that we both entirely agree on what is best practice.
