Glue the inner edge of the new foam ring to the speaker cone using speaker repair adhesive. Let it dry for two hours.
The crossover network uses capacitors that dry out over time. This affects sound quality, leading to "muddy" bass, rolled-off highs, and a general loss of clarity. While less urgent than refoaming, a "crossover recap" is often recommended to restore the speaker's original sonic balance. cerwin vega at40 specs fix

A: No. Speakers are designed as a system with the enclosure and crossover. Using an incorrect woofer will likely result in poor sound quality or even damage. Your best bet is to find an exact replacement or consult a professional about a suitable modern alternative. This affects sound quality, leading to "muddy" bass,
: Replace the old capacitors with modern film capacitors of the same value. This often restores the original "bright" and "lively" sound characteristic of the AT series. Level Control Cleaning : The Issue
The most common point of failure for any vintage Cerwin-Vega speaker is the foam surround on the 10-inch woofer. Cerwin-Vega famously used a vibrant red/orange foam. Over 30+ years, this polyurethane foam undergoes a process called chemically-induced rot. It becomes brittle, sticky, and eventually dissolves, leaving gaps around the cone.
Use a digital multimeter to measure the DC resistance across the speaker terminals. It should read consistently between 4 and 6 Ohms.
