This is a buyer’s market for exotic high-end horns, and EUR 16,500 looks like a fair-to-good entry point for a clean Avantgarde Trio Omega rather than an inflated ask. Direct used-market data is thin, so it is difficult to place the price precisely against quartiles, but the model’s rarity and original cost support the figure if this is a complete, well-presented pair.
The Trio Omega’s appeal is its huge scale, explosive dynamics, exceptional efficiency, and unusually open, low-compression presentation. Its roughly 109 dB sensitivity makes it superb with low-powered valve amplifiers, while the minimalist crossover and large Omega horns give voices and acoustic instruments startling immediacy. Check that both active bass sections, amplifiers, driver diaphragms, crossover units, grilles, bases, and adjustment hardware are present and healthy; replacement logistics can be awkward. If inspection confirms originality and quiet operation, EUR 16,500 is a worthwhile buy for someone equipped to accommodate these physically imposing speakers.
