Know before you buy
The Folded Motion tweeter uses a thin, low-mass diaphragm that moves air by folding like an accordion. This design allows for a much larger surface area than a traditional dome, resulting in faster, more detailed high-frequency response with significantly less distortion.
Yes, but keep in mind that these speakers have a 4-ohm impedance. Ensure your receiver or amplifier is rated to handle 4-ohm loads to prevent overheating and ensure optimal performance.
Bi-wiring is optional. The speakers feature 5-way binding posts that support bi-wiring, which can potentially improve clarity by separating the high and low-frequency signals, but they will perform perfectly well with a standard single-wire connection.
The dual aluminum cone woofers are designed for rigidity and speed, which helps them produce tight, punchy bass without becoming muddy. By using two drivers, the speaker can move more air, providing a fuller, more authoritative low-end presence than a single-woofer design.
Yes, the speaker's internal design is specifically engineered to minimize acoustic interference caused by sound reflecting off the floor. This helps maintain a cleaner, more accurate soundstage regardless of your room's flooring material.
The Vojtko crossover is a proprietary circuit that seamlessly blends the output of the tweeter and the woofers. It ensures that the transition between drivers is smooth and balanced, preventing any harshness or gaps in the frequency range.
