[Elecraft] Speakers - Optimal Frequency Range?

[Fred Jensen]

The Hallicrafters bass reflex speaker cabinet for the SX-28 had fabulous 
flat response ... down to the deep bass if you drove it with that.  It 
also employed a fairly large speaker and was big ... very big, and took 
a few watts [8 peak, I think] to drive it.

In the late 50's, in college and on a limited budget, it was common for 
students to use 5 or 6" speakers in tight cubic boxes made of 3/4" 
plywood and stuffed with some wall insulation for the then-new stereo 
records.  They sounded pretty good and doubled as supports for the 
ubiquitous cinder-block shelving.  My roomie and I painted ours black.

Why wouldn't one of those work?
