Orion 3.3

About the Orion 3.3

The Orion 3.3 loudspeaker system by Linkwitz Lab is a high-performance, full-range open-baffle speaker designed for audiophiles seeking exceptional sound quality. It is a 3-way active system requiring multiple power amplifier channels and an electronic crossover/equalizer (ASP). The system uses four drivers per speaker: two 10" Peerless XLS woofers in push-pull configuration for bass below 120 Hz, an 8" SEAS midrange driver covering 120 Hz to 1.55 kHz, and a 1" SEAS soft-dome tweeter for frequencies above 1.55 kHz up to about 27 kHz. The drivers are mounted on an open baffle, firing forwards and backwards to create a dipole radiation pattern. The cabinet is a rigid box with no front or back panel, carefully dimensioned for acoustic performance. The crossover/equalizer is an active 3-way design with balanced inputs and optimized filters for a perceptually neutral frequency response. The system requires 6 to 8 amplifier channels, with recommended power around 60-75 watts per channel. The total material cost for building the Orion 3.3 is approximately plus about 80 hours of assembly time. The system is sold as a DIY project with detailed documentation, circuit boards, and optional construction kits. It is praised for its spaciousness, resolution, dynamic range, and holographic realism, offering performance comparable to much more expensive commercial speakers.
