In overall great condition with no significant signs of use or any deep scratches. Tested with a sweep generator and working perfectly. From the E-Sub product brochure: "The e110’s can be used in a wide range of applications, from full home theater systems to dedicated two- channel music systems, to desktop audio workstations. A true, two-way onboard crossover with high-pass line outputs allows for seamless integration with two- channel systems, while high-level inputs even make it possible to add an e110 to systems lacking line outputs."
