Benefits of Active Bi-Amping:
Quote:
1.
Effectively (up to) twice the 'real' power of the amplifiers themselves.
2. Reduced intermodulation distortion.
3. Elimination of the low frequency passive crossover, its inherent losses, potentially poor linearity and crossover point inaccuracy.
4. Reduction of the difficulty of the load presented to the power amplifier.
5. No padding is required to align the driver sensitivities, so we are not simply wasting power.
6. The damping factor is greatly improved for both the low and midrange loudspeakers.
7. Complete freedom from any interaction between the loudspeaker driver (and its environment) and the crossover network.
8. Cost savings, since complex passive crossover networks are not needed
9. Bi-wiring is included free!
10. The flexibility to choose amplifiers which are at their best within a defined frequency range.
11. Ability to match amplifier power to the exact requirements of the drivers for maximum overall efficiency.

Nó tăng công suất về mặt lý thuyết. Tăng công suất đâu có nghĩa là cháy loa, chỉ mạnh hơn thôi khi mình mở volume vừa phải. Ví dụ như receiver 140W kéo loa 100W thì nếu mở vừa phải sẽ vẫn nghe tốt và còn hay hơn 140W kéo loa 140W.
Em nghĩ thế thôi chứ cũng không chắc, để tối về test mà mở volume lớn bằng lúc chưa bi-amp mà âm thanh nghe lớn hơn thì chắc chắn là công suất tăng lên rùi.
