Point-to-point hand-soldered crossover wiring mechanically secured against movement, is a construction technique more commonly associated with the finest tube amplifiers than with loudspeakers, and Odeon Audio applies it consistently across its horn-loaded range, including the flagship Carnegie shown here. Hifiverse's own Munich 2025 verdict, an impressive scale that "literally" fills the room with a genuine presence effect, is precisely what a 97dB spherical-wave horn design is engineered to deliver.
The system at a glance
One component, a massive German three-way horn floorstander weighing 115kg per side and priced around $120,000 per pair, built specifically to demonstrate what spherical-wave horn loading can achieve. The Carnegie anchored Odeon's Munich room as its main exhibit, Odeon Audio's top-end model rather than a documented multi-brand electronics chain.
Why these components work together
The Carnegie's tweeter is a 38mm Mylar-diaphragm compression driver using ring-radiator technology, driven by a neodymium magnet generating a substantial 2.4 Tesla magnetic force, paired with a 13cm midrange driver and a 38cm woofer, all loaded through Odeon's proprietary spherical-wave horns built from 24mm multiplex plywood chosen because its cross-glued veneer layers deliver exceptional stiffness and low resonance. That combination delivers 97dB sensitivity into a straightforward 8-ohm load, an efficiency figure the manufacturer states explicitly lets the Carnegie be driven by "any high-quality amplifier concept," including low-power triodes such as 300B and 2A3 designs that would struggle to move a conventional dynamic loudspeaker's cone at all. The cabinet's design keeps every driver positioned exactly on a single acoustic axis for ideal phase alignment across the crossover points at 420Hz and 2,200Hz, an engineering priority that matters considerably more for horn-loaded designs, where driver-to-driver timing errors are more audible than in typical dynamic-driver cabinets, than for conventional multi-way loudspeakers.
How it sounds
Independent owners describe the Carnegie as delivering exceptional build quality alongside a level of everyday listening pleasure that has made it, for at least one longtime reviewer, "the last big speakers I will ever own," while Odeon's own description of the model turning music listening into "a live event" where voices and instruments appear at lifelike scale tracks directly with Hifiverse's own Munich assessment of a system whose scale fills the room and creates a genuine sense of presence.

CARNEGIE
by Odeon Audio
The top-end ODEON Audio Carnegie speakers flaunt 97 dB sensitivity and work great with low-power tube amplification. A 38 mm mylar compression tweeter with a 2.4Tesla magnetic system, a 13 cm midrange driver and a 38 cm woofer are all enclosed in branded horns made of multilayer wood composite.
