another ohms question

#2
Don't do that unless you know for certain you have a series cable. If you are not sure if you have a series cable or not, chances are you don't. (3 connections-- one ONLY for the amp, and one for each cab-- all wired extra special in one cable). If your amp has two outputs, you will be putting a 2 ohm load on your amp with those cabs using those outputs. Two 4 ohm cabs is 2 ohms. Two 8 ohm cabs is 4 ohms. Connecting the amp to one cab, then from that cab to the other is NOT series connection with standard factory connections. You need two 8 ohm cabs, another amp, or to use just one cab. (or buy/make a series cable)

To reinforce Basscooker's comments, you can't connect speaker cabinets in series using ordinary speaker cables. It can't be done. Don't try. Hweg7, this isn't so much for you as for all the others who haven't asked, but were thinking about the same question.

^^ I reread the op and was thinking the same thing. IIRC the Backline 250 is like that. I also stated in my response that you could use only one cab..... nope. You shouldn't be using either of those cabs if your amp is 8 ohm minimum.

BBBBut wait. If you're wiring a cabinet, you can use them, wired series, and then you'll have 8 ohms. If the "speakers" you mention in the OP are cabs, then no, but if you need an 8 ohm cab and have two 4 ohm speakers to put in, then wire series and you're fine.

The problem is that you need a special cable or box to do that. Daisy chaining the cabs still puts them in parallel. I have made numerous series cables. I know of a store that stocks them and will make custom ones to your spec.

Right,right. I mentioned this in my first reply. What I didn't clarify was that I didn't see in the OP he specifically mention "cabs", just 'speakers'. I thought there may have been some confusion on my part. If you have a cab that you're putting two four ohm speakers in, yes you can use them both, just wire them series. Thanks, Munji for highlighting my confusing post.

So, OP, a bit more info? Are you looking to hook up cabs, or are you wiring speakers? You can only use one if you're hooking up cabs (without a special cable). If you do buy a series cable, your amp will likely sound a teeny bit louder, but taking SS from 4 to 8 ohms drops output. While doubling cone area increases volume.... it may be a wash, or even a loss in net.
