Big league tech
In contrast to our passive ULTIMA 20, the ULTIMA 25 has particularly rich bass and a maximum volume that's a good deal higher. Additional acoustic highlights include the phase plug, wave guide, and fiberglass diaphragm.
Wave Guide for extremely precise localization of individual sound sources and detailed soundstage structure .
Phase Plug to mitigate phase-shift related wave cancellations, improving transparency and directional sound output.
Fiberglass diaphragm for high impulse fidelity and capacitance.
