I purchased a VOX AC15 Heritage this evening. As with all VOX amps, the 1x12 cabinet is fitted with a 16 Ohm speaker. I have an 8 Ohm Alnico Cream that I want to use in the cabinet, but I'm not familiar enough with the AC15 circuit to know if this will cause a change in the sound. I've used 8 and 16 Ohm speakers in Marshall's for years, and have never noticed a difference. Maybe a slight difference, but nothing that would make me choose one over the other. Question: Should I sell the 8 Ohm Cream, and purchase a 16 Ohm, or just use the 8 Ohm speaker?
