Question for Andy, Duke, Alex and the other knowledgeable amp / speaker folk. How would you feel about a 3x cab with speakers that dip to 7.4 ohms @ 150Hz, so 2.47 ohms minimum? Could you conscionably say it's good to use with any given 4 ohm capable class D head at gig levels? As another example, a deltalite 2512 II dips to 5.2-ish ohms at 200Hz, so a 2x cab would be 2.70 ohms minimum. I think there are some Eminence drivers that are a touch lower, but this is one that comes to mind and is a common commercial base model, so it's been proven to not melt amps. TIA!
