These have been kept in a smoke free home studio. Selling only as a pair. I am only selling these as I have to move studios and do a build out. PSU has just been tested and is like new. 100% perfect working condition cosmetically great. Super cool compression curves and flexibility with these things. I'm sad to see them go. Buyer pays shipping. $49.00If buyer fully insured then please contact me as shipping price may have to change as it is very expensive to do so. Thx!
