"For the metal player."

First and foremost, I mainly play all types of metal. I tried these speakers on a whim from various different reviews and from reading all of the info that Eminence has to offer on their website. I recommend checking out their website before you purchase one of their loudspeakers. They have tons of info there and you can download a PDF selection guide or even email their tech support for help on exactly what you're looking for. I am very pleased with my choice. The distorted sound of this speaker is great; it excels in the low end and has a nice, clean high end that isn't ice picky. It has TONS of headroom due to the wattage it can handle. I loaded a Swamp Thang with a Governor in a vertical 2x12 with two 2 1/2" ports in the middle. Governor on top, Swamp on the bottom. Definitely my favorite combo of speakers now. The Governor has the V30'ish mid-range British sound that most metal players desire, and the Swamp rounds it off with its powerful low end. This cab is a completely different animal now. I definitely recommend it for metal. And the best part, made in the USA!
