The ported cabinet on Leon Speakers’ new A3 Subwoofer is only 4” deep even though it holds an 8” woofer. It can be used as an in-wall, on-wall, or in-room subwoofer and is a great match for the company’s new Horizon 212 single-cabinet LCR that’s only 2” deep. As with all Leon Speakers speakers, the cabinets can be totally customized when it comes to size, finish, color, and etc. The base price of the A3 is $1,195. The Horizon 212 starts at around $1,500.
