Full Range Speakers | High-Efficiency Wideband Drivers | Lii Audio
High-efficiency full-range speakers and wideband drivers designed for tube amplifiers, open baffle systems, horn speakers and large enclosure systems.
At Lii Audio, we design full-range speaker drivers with a simple goal: preserve coherence, reduce unnecessary complexity and let music flow naturally from a single source.
What Is a Full Range Speaker?
A full-range speaker uses a single driver to reproduce most or all of the audible frequency range. Instead of dividing the signal between multiple drivers and complex crossover networks, a wideband driver works as a unified source.
This approach is valued for coherence, phase integrity and natural tone. Vocals, acoustic instruments and analog recordings often benefit from the continuity and directness of full-range reproduction.
Why Choose Full Range?
- Better phase coherence from a single source
- No complex crossover required for full-range operation
- Natural midrange and vocal reproduction
- Excellent match with tube amplifiers and high-efficiency systems
- Simple speaker design with fewer parts and less signal loss
Built for Real Systems
Lii Audio full-range speakers are designed for more than just open baffle. They are equally at home in large volume enclosures, horn speaker systems and high-efficiency setups driven by low-power tube amplifiers.
Some listeners prefer a single-driver system. Others combine a full-range driver with a dedicated woofer such as the Lii Audio W21 for deeper bass extension while preserving overall coherence.
Less parts. Less power. More music.
