Infinity 2000 AXT (1973)
At 27.75 inches tall and armed with a modified Walsh tweeter, this speaker system commands attention — and demands a careful hand in restoration.
Overview
The Infinity 2000 AXT isn't a passive box of wood and drivers; it's a statement in active loudspeaker design from the early 1970s, Introduced in 1973, this 3-way ported system pairs a 10" Q-Woofer with a 4" midrange and a dual-tweeter array — one Walsh WTL and one EMIT — to cover a frequency range of 30 Hz to 21 kHz. But the real twist lies in its electronics: an external active crossover and equalization unit that 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 in tandem. Whether that complexity translates to musical coherence depends heavily on condition — and few remain in working order.
The suggested retail price for a pair was $600 in 1973, a significant investment that placed it in the upper tier of home audio systems. Yet a pair reportedly sold for $425 in 1976, suggesting depreciation was swift — perhaps due to complexity, perhaps due to competition. By 1984, a set of four speakers was listed for $350 or best offer, underscoring how quickly such niche systems could fall out of favor.

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. This scarcity is likely due to limited production, high complexity, and poor long-term reliability. The active crossover/equalizer unit, critical to operation, is prone to age-related failures — particularly capacitor degradation — and no documentation exists on circuit topology or repair procedures.
Original pricing shows a conflict: while one source cites a suggested retail price of $600 per pair, another lists $295 per speaker. Given that the $600 figure appears in a contemporaneous state news report from 1976 referencing a new pair, and aligns with the "suggested retail" designation, it is treated as authoritative. Historical resale data shows a one-year-old pair selling for $425 in 1976, indicating rapid depreciation. By 1984, a set of four was offered for $350 or best offer, reflecting declining market interest.
No current market prices are documented, and due to the system’s dependency on non-replaceable electronics, functional units likely command premiums among specialists — if they can be verified as operational. Restoration is not for the faint-hearted; without service manuals or spare parts, repairs rely entirely on component-level troubleshooting.
