Crossovers

A deep look at the time-aligned, high-order passive crossovers built for Sunship loudspeakers — component selection, construction methods, and the design philosophy behind them.

The crossovers at the heart of Sunship loudspeakers are engineered with a time-aligned philosophy that prioritizes coherent sound above all else. Each passive network is carefully designed to integrate the horn drivers and woofers so that frequencies arrive at the listener's ear in proper phase relationship, preserving the natural timing of the original recording. The high-order slopes are chosen to minimize interference between drivers in their crossover region, reducing distortion and keeping the frequency response flat across the audible spectrum. This attention to phase and alignment is what separates a truly refined loudspeaker from one that merely plays loud.

Component selection for these crossover networks is taken seriously, with every capacitor, inductor, and resistor chosen for its sonic character as well as its electrical performance. The design team evaluates each part for consistency, stability, and long-term reliability, understanding that a crossover is only as good as its weakest link. Wiring is kept clean and direct, with solid connections that resist degradation over years of use. The result is a network that remains transparent and musical, allowing the character of the TAD drivers to shine through without coloration or smearing of the signal.

Construction of each crossover reflects the same artisan approach that defines the rest of the Sunship cabinetry. Networks are built by hand, with components carefully mounted and braced inside the cabinet to resist vibration and microphonic effects. The crossover boards are laid out with attention to signal path length and separation, minimizing interaction between stages and keeping noise low. Every unit is tested and measured before installation, with the builder listening critically to confirm that the assembled network performs as designed. This hand-built process is time-consuming, but it ensures consistency and quality that mass production simply cannot match.

The design philosophy behind these crossovers is rooted in the belief that the loudspeaker system should vanish in the listening room, leaving only the music. By keeping the network simple in concept yet meticulous in execution, the crossover allows each driver to operate within its ideal range while blending seamlessly with its neighbors. The result is coherent imaging, natural tonal balance, and a sense of ease that invites long listening sessions. Whether paired with TAD compression drivers and woofers or other high-performance transducers, these crossover designs are built to serve the music first and foremost.
