Infinity 2000 AXT (1973)
The speaker stands 27.75 inches tall and uses a modified Walsh tweeter. It takes a careful hand to restore.
Overview
The Infinity 2000 AXT is an active loudspeaker system from the early 1970s. Introduced in 1973, it is a 3-way ported design with a 10" Q-Woofer, a 4" midrange and a dual-tweeter array - one Walsh WTL and one EMIT. It covers 30 Hz to 21 kHz. The electronics are the odd part. An external active crossover and equalization unit separates and conditions the signal before it reaches the drivers,
Instead, it blends concepts: ported bass loading, active filtering, and dual high-frequency drivers working together. Whether that complexity adds up to musical coherence depends heavily on condition, and few remain in working order.
The suggested retail price for a pair was $600 in 1973, which put it in the upper tier of home audio systems. A pair reportedly sold for $425 in 1976, so depreciation was swift. Maybe it was the complexity, maybe the competition. By 1984, a set of four speakers was listed for $350 or best offer.

Collectibility & Value
The Infinity 2000 AXT is widely regarded as super rare, with anecdotal evidence suggesting only a handful exist in regions like Australia. A 2017 forum post described a set as possibly the only ones in Western Australia, and one of few on the continent. The scarcity is likely due to limited production, high complexity, and poor long-term reliability. The active crossover/equalizer unit is critical to operation and prone to age-related failures, particularly capacitor degradation. No documentation exists on circuit topology or repair procedures.
Original pricing conflicts. One source cites a suggested retail price of $600 per pair, and another lists $295 per speaker. The $600 figure appears in a contemporaneous state news report from 1976 referencing a new pair, and it matches the "suggested retail" designation, so it is treated as authoritative. Resale data shows a one-year-old pair selling for $425 in 1976. By 1984, a set of four was offered for $350 or best offer.
No current market prices are documented. The system depends on non-replaceable electronics, so functional units likely command premiums among specialists, if they can be verified as operational. Without service manuals or spare parts, repairs rely entirely on component-level troubleshooting.
