Availability: Translation missing: en.general.icons.icon_check_circle icon In stock, ready to be shipped

Separated Notch Edge Surround
The woofer surround features another proprietary technology, with distinctive curved notches improving the vertical amplitude symmetry, for dramatically reduced distortion and enhanced clarity.

Five-beam Frame Structure and Dynamic Air Diffuser
The Five-beam Frame design disperses resonance while the integrated Dynamic Air Diffuser ensures efficient air circulation for smooth cone travel and cooling of the voice coil.

Progressive Height Rate Spider
The acoustically optimized spider allows for higher power handling and airflow, with a profile designed for more rapid and precise cushioning of the speaker cone.

Phase plugs
The resonance damping phase plugs on the XS-163ES woofer and mid-range driver help realize ideal frequency response, right up to the crossover points. A rigid aluminum bobbin in the woofer and Dynamic Air Diffuser further support the speaker's wide frequency response, for controlled and dynamic sound delivery.

Tweeters to hit the high notes
Compatible with High-Resolution Audio, a soft-dome tweeter diaphragm is directly attached on the voice coil, designed to cover your music's ultra-high ends, with a frequency range extending up to 40 kHz.

Bi-amp capable crossover with gain selector
The audiophile-grade crossover features optimized, low-resistance film capacitors for clear high frequency reproduction. Plus inductive winding and air cored coils deliver crisp mid and powerful sound on demand. You will enjoy astonishingly low distortion across all frequencies, and the precision of crossover gain control, even when driving the components with a single amplifier.

Shallow mid-range driver
The newly developed mid-range driver is driven via a compact but incredibly powerful neodymium magnet. The result is a shallower basket, designed to perform even in confined spaces and challenging installations.
