Key Technical Pain Points

* Wattage Inflation: Consumers are increasingly skeptical of "Peak Power" ratings, often finding that standard power supplies cannot reach the advertised 200W-600W outputs. Reddit

* Crossover Control: A major user complaint is the lack of a "true" adjustable crossover on entry-level boards, which often only offer simple bass volume knobs rather than frequency filtering. Thechargestations

* Connectivity Quality: Cheaper boards frequently suffer from high-frequency noise ("hiss") and inconsistent Bluetooth pairing stability. Thechargestations
