Altec 606 (1945–late 1960s)
A bass reflex corner enclosure designed for 12″ and 15″ speakers, produced by Altec from 1945 to the late 1960s.
Overview
The Altec 606 is a bass reflex corner enclosure from Altec Lansing. It goes in a room corner. It was produced from 1945 into the late 1960s and is often paired with high-efficiency drivers like the 604D Duplex. The corner placement gives the cabinet a better acoustic loading environment, which improves bass response and efficiency. It has a lively sound with strong midrange and high-frequency reproduction, particularly with original components.

Design
The 606 is a corner cabinet. The room corners act as part of the enclosure, which effectively increases its volume and improves low-frequency response. It was intended for high-efficiency drivers such as the 604D Duplex and can be paired with the N1600B crossover. Some units have been modified with other drivers, like the Tannoy dual concentric, or with Altec 416 and 511b components in DIY builds.
Market
Current asking prices reach $2,950 for a single 606 cabinet and up to $5,000 for a pair. It stays popular with audiophiles and DIY builders who use it as a base for builds with other Altec or vintage components.
