The Lowther PX4: Power Is Not the Point. Most amps chase power. But Lowther speakers don’t need it. They’re efficient enough to fill a room at a whisper – and detailed enough to stop time while doing it.
That’s why we built the PX4. A classic British amp delivering just 10 watts of pure Class A beauty – no noise, no distortion, no struggle.
It’s not about driving the speaker. It’s about revealing it. The PX4 is designed pecifically for Lowther drive units – to let you hear everything, exactly as it is, even at low volumes. Other amps show off. Ours shows you the music.
