That price shows what a mark-up the distributor takes (although remember the customs duties as well as the shipping costs), as the last price I recall in the US for the Sovereigns was in the $20,000+ range, and the Princesses (which I bought for $7700 list in 1987) were over $11,000. Duntech made some new designs after John Dunlavy left--one, called the Prince (LOVE the name) looked like the Dynaudio Temptations and listed in the $15,000+ range, I believe, though factory direct they should be far less. Much less wide than the Sovereigns, as they used multiple 8 or 10 inch drivers instead of the bigger 12 inch bass drivers of the Sovereigns.
As a note, when Harry Pearson reviewed the Sovereigns for TAS in the late 80s/early 90s, he gave what the market perceived as a lukewarm review (liked certain things about them but felt the design needed to be updated which, as turned out, Dunlavy himself did with his SC-V), and a whole slew of Sovereigns turned up on the used market in the AudioMart publication shortly thereafter for as low as $4000. If you match them with the right amplifiers in the right room, they can be quite competitive with modern designs, and that price they'd be a steal.
