I'm going to build myself a 2x12 cabinet for my AC15. I'm putting the Celestion Alnico Blue inside the 2x12 cabinet, but I want to pair it with something different for the second speaker. I'm already well versed when it comes to wiring it all up, series vs parallel, matching ohms, all that stuff. So my question is more about tonality... I've seen a lot of cabinet makers pair a Celestion Blue with a Celestion G12H Anniversary (pairing the alnico with a ceramic). I kinda like that idea. Is that a good way to go? The other thing I'm wondering about is how to properly pair my Alnico Blue with an equally (or similarly) efficient speaker... That alnico blue is very "efficient" (loud), and I don't want it to drown out the other speaker I pair it with. Any thoughts would be helpful!
