Highlights
Why we love this product
The ULTIMA 25 ACTIVE Surround is our plug-and-play complete Surround Sound set. No need for a bulky amplifier or AV receiver - the speaker comes with a receiver built in. The subwoofer and rear speakers are paired wirelessly. And all that with the award-winning ULTIMA sound our fans know and love. What movies will you fall in love with next?

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.
