SUB

[Ghis]

Je viens d'acheter un Mark Bass Marcus Miller 500. J'ai aussi un sub 15". Sur l'ampli J'ai juste 1 sortie. Puis-je mettre un splitter pour aller au haut-parleur de l'ampli et au sub?

Thanks to Google Translate:

I just bought a Mark Bass Marcus Miller 500. I also have a 15" sub. On the amp I only have 1 output. Can I put a splitter to go to the amp speaker and the sub?

We'd need the impedance (Ohms) rating for both the amp and the cabs.

Amp 4 ohm, sub 8 ohm

Do you mean a 15" bass guitar cabinet or a 15" PA subwoofer? There is a huge difference.

Is your Markbass just an amplifier or is it a combo? The Marcus Miller 500 could be either one.

Non, tu ne peux pas faire cela sans connaître l'impédance de ton speaker du combo. Si l'impédance de ton speaker est aussi de 8ohms alors tu peux faire une « Daisy chain » aussi. Je ne connais pas des câbles « splitter » pour speaker

It would be helpful to translate comments into English when being posted.

FWIW: The Google Translation for the original post is pretty spot on, though it's more obvious in French that they're talking about a combo Markbass amplifier.

Fonkamex is saying you can't connect the extra speaker to the Markbass combo amplifier without knowing the impedance of the combo's speaker. They say if both speakers are 8 ohms, then you can daisy chain them, but that he's not aware of any "splitter cable" for speakers.

But OP said the Markbass combo speaker is 4 ohms and the sub speaker is 8.

If the combo speaker is 4 ohms, than it can't support an extension speaker if the amp's minimum load is 4 ohms.

Usually a combo won't have an extension speaker out if it can't safely drive an extension. However there are exceptions, so it's best to be cautious and do a bit of research.

The Marcus Miller 500 head is 4 ohms minimum. I believe the power rating is 500W at 4 ohms and 300W at 8 ohms.

AFAIK the OM does not specify the impedance of the internal speaker. If the speakers in the combo presents a 4 ohm load, you can't add an extension. If the load is 8 ohms, you can use an 8 ohm extension cab.

I suggest checking the impedance of the internal speaker array. I would be very surprised if it's not 8 ohms. FYI the Marcus Miller 102 extension cab is 8 ohms.

Looks like the CMD 102 500 Marcus Miller has a large port on the back.

This means you should be able to view the back of at least one of the drivers.


The impedance of the individual drivers may be marked on a label in the center of the magnet.

The total impedance of the internal speakers should be either 1/2 or 2 times the impedance indicated on the driver. For 8 ohms you need either two 16 ohm drivers in parallel or two 4 ohm drivers in series.
