I need to replace the power adapter for my Mirage LFX-3 crossover.
The supplied adapter puts out 18 volts AC. However, the back of the crossover where the output of the adapter goes indicated that it takes 16 volts AC. See attached photo.
So, looking for a replacement power supply, should I look for a 18 volt AC output or a 16 volt AC output. Aside from 2 volts, what is the difference between using 18 volt or 16 volt supply? Is there a downside or an upside to using 18 volts if 16 volts is specified by design. Why? I assume that Mirage thought that 18 volts was OK (probably what was available off the shelf). But, I would prefer to do what is best rather than what is potentially just OK. I would ask Mirage, but they don't really exist.
Thanks for the help!

I would probably go with the 16VAC unless you tend to have low AC line voltage, but also make sure the power rating is adequate,
similar to the one originally supplied. Do you have a schematic?

Thanks. I have a schematic (attached), but it is not clear to me from that (a corner of that schematic is cut off --- that all that could be found, but the corner that is cut off is the same as for the Mirage LFX-2 crossover (also attached)
I asked Klipsch product support (they bought and eventually killed the brand) and they gave me an answer that didn't make much sense to me (I'm not an electrical engineer, but do have a science/engineering background). They said, "You want to replace the adapter with an 18 volt to keep in aligned with the speaker."
Does that make sense? The only connection between the crossover and the subwoofers (BPSS-210's) is the line level output from the crossover(1-2 volts?). The BPSS-210 subwoofers run on 120 Volts AC house current (although I assume there is a transformer in the sub). I have the schematics for the subwoofers if that of interest.
Thanks!
