Philharmonic COLLECTION

Our most refined offering of instruments.

The Philharmonic Collection represents our most refined offering of instruments. This selection features only three exceptional designs - PM4A, PM7A, and our Field Coil - each chosen for their perfect embodiment of the Lowther sound that has captivated listeners for generations.

Distinctive, superior engineered metalwork with nickel chrome finishing elevates these instruments to objects of both acoustic and visual beauty. Our Philharmonic drive units combine aesthetic elegance with functional excellence.

The sound character of these instruments - natural, detailed, and emotionally engaging - has been refined through extensive listening tests by our most experienced craftsmen. Small enhancements across the entire spectrum come together to create sonic presentations that connect listeners more deeply with their cherished recordings.

These instruments are the standard fitment in our highest-tier acoustic masterpieces, chosen not only for their technical excellence but for their ability to reveal the heart and soul of musical performances.
