Single 18" Active Subwoofer


For the powered ATEC series we partnered with one of the world's leading amplifier manufacturers to create a high powered active double 18" subwoofer using the most efficient Class D amplifier design and the very latest high-current Switch-Mode Power Supply technology.

The ATL118BA-V2 is designed to be flown in AT208A line array systems and features extremely high quality cabinets made from Baltic birch plywood. Because we design and build our products in our own manufacturing facility in China you can be assured of our commitment to producing an extremely high quality product.

Furthermore our in-house R&D centre is also home to an impressive measurement and testing lab where we rigorously check every product for sonic quality safety of rigging systems exposure to dust and moisture and electronic safety and emissions. We stand by the quality of our products we build them right and we build them to go the distance.
