Hey all,
My friend and I recently picked up a pair of Audio Centron ce50 speakers. I’m powering them with a QSC amp.
The issue I am having is that the two speakers are not wired the same, even though they certainly are the same model. The one speaker is wired how I want it to be: full range. A single 1/4” input delivers to all speakers. The other speaker is wired for three-way, tri-amped input. A 1/4” input delivers to only some of the speakers, with the different input jacks corresponding to different speaker groups within the cabinet.
Can I please have some help figuring out how to modify the three-way speaker so it will accept a full range input?
I do understand the underlying principle at work here. The three-way speaker needs signals from 3 amplifiers, each of which receive a signal from a crossovers or band pass. The full-range input has the crossover inside the cabinet, and can be fed a full-range signal.
Despite doing some internet searching, I can’t find the info I want. I assume I can do this somewhat easily. Soldering and replacing transistors or capacitors is in my skill range.
I have no idea why the two are wired so differently. The full range input sounds good enough for us, if we can manage to get the other one working in the same way we will be in business.
Thanks I hope to learn something today.

Something like this; https://www.ebay.co.uk/itm/29653925...7Cxa68hPYNkZOb0FYJQ+sftA==|tkp:Bk9SR6bGoZGRZA
installed inside the cabinet will do what you want.

It would be simplest to make up an adapter cable for the tri-amped speaker.
One female 1/4" in-line input jack input goes to three 1/4" in-line output plugs (all in parallel)
Just be sure to keep all the ground leads connected together for the proper polarity of connections.

Yep there it is, looking fine. Good and sturdy, I like to sit on top of it after practice.
Ok so those boards look like a good, permanent solution. I wonder though, should I replace the other one as well to make sure they are matched up correctly? Or are these things pretty standard?
If I make an adapter myself, will I need to use speaker cable, or can I chop up some instrument cables I have around? I know it’s inadvisable to use a run of instrument cable to power a speaker, but how about small pieces?
To that end, could I use two (short) 1/4” TS Y cables? The first Y goes to a speaker and the second Y. The second Y goes to 2 speaker inputs.
Would that be parallel? I understand how that works with guitar pickup wiring but I can’t wrap my head around the logistics here.

Can we assume the separated ones simply need to be joined together or are the sides different in other ways? Can you create a schematic of each side?
Yes! 👍To that end, could I use two (short) 1/4” TS Y cables? The first Y goes to a speaker and the second Y. The second Y goes to 2 speaker inputs.

However, you need to make sure the speakers are still connected to the passive crossover.
If the passive crossover is bypassed or removed, the above connection will not work!
