Description from the seller

ITT vintage loudspeakers, known for their compact spherical enclosure that minimizes resonances and offers an unusually wide dispersion of high and mid frequencies. Thanks to the spherical cabinet construction, diffraction is greatly reduced, resulting in an exceptionally natural stereo imaging and a clear, detailed sound character.

The speakers are equipped with a broadband driver with a lightweight cone and high sensitivity, making them easy to drive with both vintage receivers and modern amps with low to mid-high output power. The internal damping and acoustically optimized cabinet size ensure a controlled response in the midrange and a surprisingly full sound for their size.

The feet are custom Padauk wood stands that add an extra aesthetic dimension.

Technical specifications (generic ITT Kugel design):

- Broadband speaker with accurate high-frequency reproduction
- Spherical ABS or plastic enclosure for minimal cabinet coloration
- Nominal impedance: typically 4–8 ohms
- Power: 10–25 W RMS (depending on model)
- Frequency range: approx. 80 Hz – 18 kHz
- Wide dispersion due to omnidirectional geometry
- Suitable for near-field and room-filling applications

These speakers combine classic ITT engineering with a unique acoustic design, ideal for collectors, vintage hi-fi enthusiasts, or anyone seeking a precise, characterful broadband reproduction.
