Because the cabinet uses a tuned bass-reflex design, air moves efficiently out of the port to reinforce subterranean rumble without straining your amplifier. 2. The Midrange and High-Frequency Assembly cerwin vega at-40 specs

The is amplifier-friendly. Most solid-state receivers from the 1990s onward will have no trouble driving these. The crossover points— 500 Hz and 5 kHz —are well chosen. The woofer handles the lower frequencies where cone breakup isn’t an issue, the midrange covers the entire vocal and upper bass region, and the tweeter only handles the top octaves. This results in smooth polar response. The core appeal of the Cerwin-Vega AT-40 lies
