Merry Christmas!

Today I pulled another long-time waiting project from my shelf...a Phonola cathedral, built by Grimes Radio Corporation, which later became Dominion Electrohome Industries. I bought it 16 years ago...where did time go? It is a model #161, built in 1931. 

It uses two 235s, two 224s, a 247, and a 280 tube. 

But...it is missing it's speaker. And the schematics I have don't give any specifications, other than it would have a 1800 ohm voice coil. Would anyone be able to "reverse engineer" from the schematic, and give me an idea of what I should be looking for?
