Pairing cabs

[jdt]

Hi, forgive the question, if i paired a same ohm, and speaker type, cab, with a
markbass, cab, would this be ok. would need to know what other cabs carry the same
spaekers.

Try it & see - just make sure they are not out-of-phase. (The old 9v battery trick....)

The [i]only[/i] rule when running 2 or more cabs is to keep the combined ohms within the limits of your amp.

After that it's down to preferences and your ears. Some cab combinations don't sound good and some do.


Which cab do you want to put with which MB cab.

Thanks, lost on the battery comment, just wanted a 2x10 to go with 2x10 markbass cab, was thinking of a 112 fender cab,

I know nothing about Fender cabs, but I'd start by suggesting you get another MB 210. That would sound best.

If you already own the Fender and the ohms are right (both 8 ohm cabs) connect it up and see what it sounds like.

There's two parts to your question. is this ok as far as the amps and speakers are concerned and how will it sound.

You can do this perfectly safely with a solid state amp if your existing cab is 8ohms or 16 ohms and the second cab matches the ohms of your Mark Bass. Two 8 ohm cabs will give you 4 ohms overall and two 16's will give you 8 ohms overall. If you use a valve amp you will have to match the output to the speakers overall impedance. In each case the power handling will be twice the power handling of the weakest cab.

If your speaker is 4 ohms it is possible to add a second cab but you will need some special leads or to rewire your cab, if you just plug them in your amp will struggle and may die on you. If you absolutely want to go ahead with 2x 4 ohm cabs then you need to come back to us.

As to how it will sound, if you add a second MB cab it will sound the same but louder. If you add anything else you will lose the identity of the MB in the sound and of the other speaker too, the sound sort of blurs together and the only practical way of knowing what you will get is to try it.

[/quote]Whatever you're thinking about don't pull the trigger until you've actually tried the two together, as there's no way to predct the result. The only safe combination to go with without hearing it first is two identical cabs, which will sound the same as one, but louder.
Beware the urge to add a different cab to make up for deficienies in your existing cab. If, volume aside, your current cab doesn't sound good, don't try mixed cab voodoo to fix it. Get rid of a cab that you don't fully like and replace it with one that you do.

Battery test......take a cabinet, plug in a speaker lead to it, take the other end, which has to be a jack plug, place the barrel of the jack plug onto a negative terminal of a 9v battery and then touch the jack tip onto the positive of the battery. All speakers should move outwards and with a very audible 'click'. If you find, say within a 2x10 cabinet, that one speaker moved in and the other outwards, then the speakers are deemed as 'out of phase' with each other and obviously the cabinet has been incorrectly wired within itself. This also applies to two cabinets, all the speakers of both cabinets should move outwards together so they are 'in phase' with each other.

From experience out of phase speakers sound cack.

I don't think the Fender 112 is a 2x10?
The 112 in the title suggests it may be a single 12".
