    I have a speaker cabinet with 8 ohm Celestion Vintage 30. If I were to get the MT-15, could I use this cabinet and plug into one of the 8 ohm input jacks where it says 8 ohm parallel or do I need a 16 ohm speaker?

    If all the speakers in parallel have the same impedance, then the calculation is easy. Simply divide the impedance by the number of speakers in parallel.

    Example 1: Four 8 ohm speakers in parallel: 8 divided by 4 = 2 ohms.

    Example 2: Two 16 ohm speakers in parallel: 16 divided by 2 = 8 ohms

    Through the magic of Math, a 8 ohm and 16 ohm speaker in parallel works out to 5.3 ohms impedance

    here's a link that has a calculator built in, that will be more helpful than I am.

    You’d plug an 8 Ohm speaker into one of the 8 Ohm output jacks. The HXDA and DG30 have parallel 8 Ohm jacks, and that’s how an 8 Ohm speaker cab is connected to them as well.

    If you’re at all concerned, give PRS Customer Service a shout.
