Can burn loudspeaker and transformer due DC flowing
Dc quite probably saturates transformer core-> lots of distortion and very little sound
Even if works the transformer is expensive and limits sound quality
Very low impedance sound input is less than 30 ohms – which means this circuit does not work properly with most sound sources, should be driven with an amplifier!

Due to its extremely low impedance sound input of less than 30 ohms, this circuit requires an amplifier in order to function correctly with the vast majority of audio sources.

DC flowing through a loudspeaker or transformer causes core saturation, heavy distortion, heat, and risk of damage. Transformers are costly and limit sound quality, and with input impedance under 30 Ω the circuit won’t work properly with most sources—it really needs an amplifier to drive it safely.
