Since the manufacturer doesn't specify what your existing speaker's impedance is, you will have to determine that from the markings on the existing speaker. If there are none, you will have to measure it.

If any of those tasks are beyond your skill level (and based on your questions, I suspect you might not have a lot of experience with this sort of thing), you should get help from someone who has the skills.
They can demonstrate how to do it, and help you learn.

Those are both very different questions, and get very different answers.]]> Live Sound kent_eh https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366178 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366112 Wed, 27 Apr 2011 12:39:16 +0000 Live Sound ApaItuGempark https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366112 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366082 Mon, 25 Apr 2011 22:20:47 +0000 http://www.teamrocs.com/technical/pages/connectingspeakers.htm]]> Live Sound greybeard https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366082 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366078 Mon, 25 Apr 2011 17:14:46 +0000 Live Sound ApaItuGempark https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366078 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366064 Sun, 24 Apr 2011 21:28:57 +0000
The cab doesn't need "power", it gets its energy from the signal to the driver (i.e. speaker).

The problem with speakers is that they like to have the signal presented "just so" - 8 Ohms, 16 Ohms, etc.. You can connect speakers so that their resultant impedance is modified by the way that they are connected, So, you can connect two 8 Ohm speakers to give 4 Ohms (parallel) or 16 Ohms (series) - but not 8 Ohms. You can connect 4 8 Ohm speakers to give 8 Ohms ( two parallel pairs, connected in series or two serially connected pairs in parallel).

Whether your Nux will feed the cabs depends very much on their impedance.]]> Live Sound greybeard https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366064 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366061 Sun, 24 Apr 2011 17:29:52 +0000 Live Sound ApaItuGempark https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366061 https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366058 Sun, 24 Apr 2011 11:16:54 +0000

You'd have to check the impedance of the speaker cabs, in relation to your Nux. If one of them is 8 Ohms - you have a match. If they are 16 Ohms, you could connect two of them in parallel to get 8 Ohms. If they're 4 Ohms, connecting two in series will give you 8 Ohms.]]> Live Sound greybeard https://guitarnoise.forum/live-sound/combo-speaker-to-cabs/#post-366058
