Cerwin Vega At40 Specs __exclusive__ Jun 2026

If you find a pair of Cerwin Vega AT40s with intact cabinets, buy them. Budget $50 for a re-foam kit and one afternoon of work. Once restored, these speakers will give you a 38Hz low end and party-level volume that puts most modern $1,000 bookshelf speakers to shame. The specs don't lie—this is a high-efficiency legend.

This speaker is highly efficient (approx. 98 dB sensitivity ). This means it requires very little amplifier power to produce loud volumes. While many high-end audiophile speakers require massive amps to drive them, the AT-40s can rock the house with even a modest receiver, making them easy to drive. cerwin vega at40 specs
