I think this criticism assumes the T44 is trying to be something it is not.
The T44 is not really designed as a high-output SPL monitor or a large-room reference speaker meant to play at punishing levels. It is better understood as a high-fidelity tower for modern listening spaces: compact footprint, powered bass integration, good imaging, strong tonal balance, and enough output for sane real-world listening levels.
Could you argue that a 4.5-inch driver crossed that low has theoretical dynamic limits? Sure. But that does not automatically make it a design failure. Crossover frequency by itself does not tell the whole story. Driver excursion, enclosure loading, filter slopes, DSP, powered bass behavior, protection, and the speaker’s intended listening distance and playback level all matter.
A limitation that may show up when you push the speaker beyond its intended use may not be meaningful at the levels and room sizes this product was actually designed for. Not every speaker is engineered to be a studio main monitor, a PA speaker, or a large-room cinema system. Some are engineered to sound refined, coherent, and full-range in normal living rooms.
GoldenEar has earned a pretty solid reputation for sound quality, imaging, and clever bass integration. Sandy Gross may no longer be directly involved, but the design philosophy associated with GoldenEar did not suddenly disappear. You may not like the design tradeoff, and that is fair, but calling it “insane” or “stupidity” seems like judging the speaker against a use case it was never really intended to serve.
