About the Sugar Cube Speakers:
These tiny speakers are the best! Some say they sound better than much larger speakers, and I would have to agree. I’m use them exclusively for my HO collection. They are full-range speakers and are surprisingly loud for their size. They come with a baffle that I made. I ship them unassembled, assemble yourself and save!
