FRANKFURT (Reuters) - Buyout group Ardian has picked investment bank Macquarie MQG.AX as its advisor for the sale of German professional loudspeaker maker d&b Audiotechnik, two people close to the matter said.
Ardian is expected to launch an auction shortly for the maker of speakers for stadiums, concert halls and conference rooms, in a deal that may value d&b at more than 600 million euros ($665 million), they said.
Ardian and Macquarie declined to comment.
