Before the Popori Acoustics Ultra became a standalone creation, its ancestor already existed — hidden within the legendary XR1 system.
That earlier version, then called HR1, covered 700 Hz to 22 kHz and used a diaphragm just half the size of today’s model.
Now, with a frequency range extended down to 500 Hz and nearly twice the radiating surface, the Ultra delivers superior resolution, transparency, and effortless dynamics — the result of meticulous re-engineering and more than two decades of electrostatic expertise.
Once available only as part of the XR1, it now stands proudly on its own — or pairs perfectly as the ultimate upgrade for the WR1 Sicambria, completing the evolution in the WR1 Sicambria Ultra system.
