Many generic databases list the AT-40 crossover frequency incorrectly, or owners try to bi-amp them using wrong data points. The AT-40 utilizes a unique "Stroker" passive radiator setup. The crossover point between the massive 15-inch woofer and the midrange driver is roughly 500Hz to 600Hz , and then again from the midrange to the tweeter around 3.5kHz - 4kHz .

After the fix, measure impedance: you should see a twin-peak between 38 Hz and 65 Hz, and a single smooth rise after 2.5 kHz. The AT-40 utilizes a unique "Stroker" passive radiator setup

The bass sounds "flabby," distorted, or there's a noticeable "scratching" or "buzzing" sound, especially on low-frequency notes. This often gets worse with age.

However, a common "spec fix" mistake owners make is looking at the raw woofer specs. The 15-inch woofer in this cabinet is not designed to play full range; it relies on the passive radiator to control its excursion below 30Hz.
