It seems like everyone these days has a multi-room speaker system – the latest entrant is Marshall, the amp maker that brought its signature style to portable consumer speakers in recent years. The speaker maker is introducing three new models today, each of which packs Wi-Fi connectivity and multi-room capabilities.

The Acton, Stanmore and Woburn multi-room models go up in size from compact to quite large, and each resembles the classic vintage Marshall amp styling that the company is known for. The Acton is $250, the Stanmore is $50 and the Woburn is $600, and features two 5.25-inch woofers along with 110 watts of output power.
