    I’m going to order an custom-made, open-back speaker cabinet for a 12” speaker and I wonder if it might be a good idea to have an extra 10” speaker hole for adding a second speaker in the future, to switch between them or using them simultaneously.

    The reason is that the single cab would take up less space that having 2 separate cabinets.

    I now wonder if strange tonal anomalies will happen as long as the second sound hole is not used or when just one of two speakers is in use.

    Does anybody have some experience which he might share?

    There's no reason you can't mix them, but impedance should match, and choose speakers of about the same efficiency. Otherwise one will overwhelm the other.

    Hi, thanks for your replies! Yeah, I need to figure out the right combination of speaker impedance and wiring schematic.

    Meanwhile, I found a really informative video about tonal differences when not all speakers are installed vs. the standard, full configuration of closed and open back cabinets:

    I would imagine that mixing the sizes of a pair of speakers could be a good thing. Why not also consider mixing magnet types? Say on the 12 inch, Alnico and a 10 inch, Ceramic or vice versa. (Or is the second speaker an 8 inch?)

    I made a Bandmaster Reverb into a combo amp years ago, I used one 10" and one 12" Eminence alnico speakers and it was a good blend, really don't know why I sold that amp .....
    Some folks do mix alnico and ceramic speakers too, no experience with trying that.

    I picked up a 1x12 open backed cab made by Zilla that came with a second baffle with a 10 and 12 in it I put some curious wiring in on a champ using a stereo jack that allowed an 8 ohm 10" to be in series with the combo speaker with a 16 ohm 12" in parallel so the overall load to the amp was still maintained at 8 ohms

    Worked really well
