Advent Large Advent 5012 (1970)
A floor-standing acoustic suspension loudspeaker with a 12-inch woofer and 2-inch dome tweeter, designed as an upgraded successor to the original Advent speaker.
Overview
The Advent Large Advent 5012 came out in 1970 as a direct evolution of the original Advent Loudspeaker. Advent Corporation built it as a floor-standing speaker with a 12-inch acoustic suspension woofer and a 2-inch dome tweeter. The crossover frequency is 1.2kHz. Frequency response runs from 38Hz to 15kHz. The sealed cabinet measures 25 x 14 x 11.5 inches and weighs 55 pounds per enclosure. It sold for $200 per pair, keeping the brand's high performance at an accessible price.
Design
The cabinet is sealed (acoustic suspension). Advent championed this design for tighter, more controlled bass than ported systems. The 12-inch woofer works inside this airtight enclosure, which contributes to improved low-frequency linearity and reduced distortion.
Context
The Large Advent 5012 was positioned as an improved version of the original 1969 Advent Loudspeaker. It has a larger cabinet, an enhanced crossover network, and greater bass extension. Stereophile (December 1971, p.38) noted that Advent's acoustic suspension designs "delivered a level of bass accuracy and transient response previously unseen at their price point," a trait carried forward in this model. It offered higher output capability while keeping the sonic neutrality and value of the Advent name.
