You can't go wrong with the ULTIMA 25. The excellent price to sound ratio, the modern ULTIMA sound and its many connection options will win over you and your friends.

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.
