Altec 500W

Almost nothing is documented about the Altec 500W as a distinct model. The designation shows up in period advertising for the A7-500W-1, a variant of Altec's "Voice of the Theatre" speaker system. High Fidelity (July 1966, p.19) listed the A7-500W-1 alongside the 846A Valencia. It noted the Valencia shared "same components as famous A-7 'Voice of the Theatre' system" at $333. That ad suggested the A7-500W-1 was the full-sized professional reference system, sold into studios and larger home installations.

It is unclear from the surviving record whether "500W" ever existed as a standalone product separate from the A7-500W-1 assembly. No specifications, driver complement, crossover details, dimensions, or production dates have been found for a model called simply "500W." The available documentation treats the A7-500W-1 as a complete system - not a component sold under the 500W label alone. The 500W is known only as a suffix on the better-documented A7 system.
