The world's lightest 1x15 bass cabinet. The AT 115 is ideal for any type of concert, from small clubs to large stages. It is absolutely a full-range cabinet with a warm and deep sound that only a 15" woofer can guarantee. It can be used independently or as a cabinet to add to a 1x12 or 2x10 or even 4x10. The 15" woofer has been designed to be much more efficient than many other 15" woofers.
