martthebass Posted January 17, 2014 Posted January 17, 2014 Despite playing for longer than I care to remember I've always used combos or single cab solutions. I'm looking at going for a two 12" cab solution running from from MB LM3. My stoopid question is; with a single speakon output and cabs with a single speak on input how do I connect up the 2 cabs for a 4 ohm load? Quote

The speakons would be connected inside the box in parallel. OBBM, a recommended BCer, has been known to build such boxes, if you can't do it yourself. You'll need three speakon cables.

LukeFRC Posted January 17, 2014 Posted January 17, 2014 do either of the cabs have two sockets? if they are wired in parallel then just plug the second cab into the first as well? Quote
0175westwood29 Posted January 18, 2014 Posted January 18, 2014 Just go out of the head into the first cab and then link the cabs together Andy Quote
xgsjx Posted January 18, 2014 Posted January 18, 2014 Why not just use both outs on the back of the LM3? One to each cab. Quote
chris_b Posted January 18, 2014 Posted January 18, 2014 (edited) +1 The LM3 is a great amp and does have 2 speaker ouputs. It has 1 speakon and one 1/4", so you just need 2 different leads. Edited January 18, 2014 by chris_b Quote
chris_b Posted January 18, 2014 Posted January 18, 2014 Have you bought the cabs yet? IMO, a 500 watt amp with 2 12" cabs is an ideal rig, but I'd always get a cab with 2 sockets so you can daisy chain if you need to. Quote
martthebass Posted January 19, 2014 Author Posted January 19, 2014 Thanks for the answers guys. Cabs will be a pair of NY121s. Not sure if there are two inputs on the back of these....there was on my old 151HR. If there are 2 then ill daisy chain if not then different leads. I was concerned about using standard jack speaker leads, I thought it was necessary to use speakons with 500W output amps? Quote

[/quote] good quality jack to jack leads will be fine, or you can always get a speakon to jack lead, i have one aswell as a standard speakon lead as some cabs we use on gigs like old marshalls or ampegs have a jack input. andy Quote
chris_b Posted January 19, 2014 Posted January 19, 2014 Find out what you need and get your leads from OBBM, BC member. Quote
xgsjx Posted January 19, 2014 Posted January 19, 2014 The Markbass combos use the jack socket to connect to the head & I use a jack to jack lead to connect another cab (the speakon on the LM head is a dual speakon/jack socket. Before speakons came to be, all cabs & PA systems used 1/4" jacks. Quote
