Having worked for Lafayette for 14 years, I'm certainly familiar with the Criterion lineup of speakers. Most are not particularly good, but many were good for the money. Where else could anyone get a speaker that actually sounded good for only $29.95?
The initial post says "big" 3-way speakers. How big is "big?"
Up until the mid 70's, all Criterion speakers were made in Japan. Then, for a couple of years, they were made in America and had CTS drivers, foam grilles that usually fell off, and horribly finished cabinetry. This lineup was designated with each model number yielding three numbers: the 333, 555, 666 and so on. The 666 and 777 were actually pretty good speakers., at $79.95 and $99.95 each.
Then, around '75, the 2001 was introduced, and was made by Utah. It was designed to sound more like BIC speakers than the previous, triple-digit lineup, and actually received a "Best buy" rating in Consumer Reports. Utah couldn't keep up with the demand, so its successor, the 2001+, was sourced again from Japan.
ESS made a number of Criterion speakers too, but they were all 2-way systems. Most ESS-sourced Criterion speakers were petty good values, and sounded fairly decent.
