From PRS:

PRS Archon speaker cabinets feature a closed back design, delivering punch and tight low end. The Celestion V-Type speaker was chosen for its ability to maintain a balanced tonal signature from the Archon’s exceptional clean channel through classic crunch and modern metal gain. Wrapped in black vinyl and outfitted with British-style knitted weave grill cloth and PRS Signature logo, Archon speaker cabinets have a clean and powerful look. Their rugged construction means players can trust them out on the road for years to come.
