I didn't know British speaker maker Castle, but its new 70s-inspired stereo speakers look really cool — and I'm intrigued by the unusual driver layout on one model

The Castle Tantagel and Walmer speakers, in a dramatic black room.

• Castle unveils four new loudspeakers in two ranges
• Castle Tintagel sell for lower prices, with refined driver combos
• Castle Walmer are a higher price, and one has an unusual driver layout

When you think about British Castle, you probably think about Windsor, Warwick or the Tower of London; little did I know that the name also referred to a brand making old-school-looking loudspeakers.
