[TA Forbes]

The Wells-Gardner 2DL series often used two speakers. They were similar in many ways to your S.W.

You find the 2DL chassis in Coronado, Airline, Truetone, and, of course, W.G. sets. They range from 20 to 30 watts output.

Funny thing... with the exception of the Airline movie-dial sets that used this chassis, you often find them for VERY cheap. In fact, a Truetone model recently sold on eBay for 80.00!!
