Funk Audio
Classic 18.0
Introduced 2013$9,875 MSRP
The Classic 18.0 is a sealed, single-18-inch-driver subwoofer hand-built to order by Funk Audio, a tiny Alberta, Canada shop that designs and assembles its own cabinets and offers near-limitless custom wood finish options, selling direct with no mass retail presence. Audioholics' measurement-based review called it "flawless" for its combination of performance, build quality, and value, and it is a recurring recommendation on AVSForum and Audioholics forums as a top-tier compact high-output subwoofer (Audioholics review).
