Some offerings of Klipsch speakers over time made more sense to be offered at the time the were offered, then now.
PWK Heritage: These stand alone, and I think Klipsch should always continue to make them, and tweak them as needed, or when advancements are available.
KG Series: Klipsch was going against the big box speakers at the time, but those aren't really a thing now; for better or worse.
Forte Chorus: These were the most popular line offered at the time, with each able to be outside the corners or walls and still be "full range." The Chorus II and Forte II are nearly the same speaker, with the Forte trading efficiency for extension, and more mid bass bunch compared to the more linear and efficient Chorus. Yes, the Chorus would be closer to the Cornwall III of today, with the Cornwall III better in nearly all respects outside placement freedom; an advantage that I don't think would appeal to as many consumers in today's market.
