The timing is favorable: this is the current 40th-anniversary generation, released in 2022, rather than an ageing model awaiting replacement. At €2,500, though, it is an ambitious ask against the broader comparable market: the median is €381, with the 75th percentile at €1,331. That does not prove it is poor value—specialist anniversary editions can command a premium—but it needs to be a complete, near-mint pair with original packaging and accessories to justify the gap.
The Duetto 40th is a serious standmount, not a lightweight bookshelf speaker: it weighs roughly 17 kg each and combines Triangle’s lively, fast presentation with a smooth magnesium horn tweeter and natural-paper mid/bass driver. Expect punchy transients, vivid midrange clarity and good dynamics, with relatively easy 88 dB sensitivity, though proper stands are essential. At this money, confirm matching serials, undamaged drivers and cabinets, grille and terminal hardware, and ideally original boxes; otherwise, negotiation is warranted.
