But what I was saying is that people who are not audio nerds, those who just want good sound for the music they like, are less likely to want huge speakers since the equipment is not a big part of their life.
These people don't exist to any great extent that I can see. Few of the many people with seriously large record collections I know care very much about sound quality.
Either you want good sound and try to get it, or you don't care. The vast majority of people don't care and don't buy speakers on the basis of "good" sound quality anyway.
And as SM has pointed out, most audiophiles (in the west anyway) prefer dinky speakerettes and strange small-driver, narrow baffle designs to what IMO are proper full-range speakers.
Anyway, more mid-80s Japanese speaker pron, this time from Onkyo.
Yet another big, ported 3-way based not-very-loosely on the Yamaha NS-2000 / 1000x concept.
The S-3000 above is smaller and lighter than the Onkyo Scepter 5001 (w432, h756, d490 for 72kgs), but does share a similar concept for mounting the woofer (30cm on the Pioneer vs 35cm on the Onkyo).
The Onkyo were also much more expensive at around 800,000yen/pair in 1986.
The mid and HF domes use a very high-tech sounding diamond coated ceramic/Titanium material that was "laser etched" in someway to "minimise distortion" (my approximate translation, so beware

).
