The Legatia X1 employs advanced ring radiator geometry—notorious for delivering flat, extended frequency response but historically plagued by poor off-axis performance. Hybrid Audio engineers solved this fundamental challenge through proprietary wave guide design that prevents phase cancellation, ensuring uniform frequency response and uniform polar radiation. This makes the X1 exceptional in car environments with the end-user's choice of either on-axis or off-axis operation with superior polar response—a breakthrough for in-vehicle installations.
With a resonant frequency of just 570Hz, the X1 transcends typical tweeter limitations, enabling use down into the vocal spectrum for two-way systems or seamless integration in three-way configurations. This wide-bandwidth capability (570Hz-20kHz) provides enormous installation flexibility—from high-crossover two-way systems to ultra-refined three-way active setups where the tweeter handles only the uppermost octaves with no strain or distortion.
The polypropylene tuned and damped chamber at the rear of the motor assembly represents proprietary Hybrid Audio engineering—reducing backwave distortion and significantly lowering the tweeter's resonance frequency to enable faithful low-octave reproduction should the system design require it. This chamber delivers reduced distortion, low-octave authority, and greater dynamics compared to conventional designs, while integrated spring-loaded push terminals ensure robust connectivity with large-gauge wiring.
One-piece machined 6061 aircraft-grade aluminum body and flange—not poured or cast—ensures the dense metal structure lacks interstitial voids that cause resonance. This precision construction reduces vibrations within the tweeter body to abate resonance and ensure effective reproduction of extremely low music tones. The machined 47.5mm knurled attachment nut provides optimized clamping strength, while the shallow 23mm depth is 4.5mm shallower than the sibling L1 Pro R2, fitting virtually any OEM or custom location.
The proprietary Hybrid Audio wave guide geometry prevents phase cancellation that plagues conventional ring radiator designs, ensuring uniform frequency response across all listening angles. This engineering breakthrough enables the X1 to work exceptionally well in car environments with both on-axis and off-axis installations—providing good polar response regardless of mounting location or listener position within the vehicle.
Unlike conventional dome tweeters where the diaphragm is terminated only at its edges, the X1 wave guide terminates the diaphragm at both edges and center. This dual-termination approach dramatically improves damping of modal distortion and resonance, resulting in cleaner transient response and reduced coloration across the tweeter's operating range—critical for accurate reproduction of cymbal crashes, vocal sibilance, and upper harmonic content.
The ring radiator diaphragm utilizes treated fine cloth material to ensure smooth frequency response while providing optimal damping characteristics. This material choice, combined with the wave guide geometry, delivers the extended bandwidth and flat response ring radiators are known for while eliminating the harsh peaks and off-axis irregularities that compromise lesser designs. The result is effortless, fatigue-free listening even during extended sessions.
Large open-space perforated metal grille protects the delicate diaphragm from physical damage while minimizing acoustic interference. The grille can be removed if desired for applications where maximum visual integration is required or where the tweeter will be mounted behind factory grilles. The perforations are acoustically transparent, ensuring grille-on performance rivals grille-off measurements.
The motor assembly features high-grade 24.5mm × 3.5mm NdFeB neodymium magnet structure with double-stacked configuration for exceptional magnetic field strength in an ultra-compact footprint. This neodymium motor delivers high force factor (12.21 T*m BL) for excellent control and damping of the diaphragm, ensuring accurate transient response and low distortion even at high output levels—crucial for competition-level performance.
At just 23mm mounting depth, the X1 is one of the shallowest tuned chamber tweeters available—4.5mm shallower than even the L1 Pro R2 predecessor. This compact profile enables installation in virtually any location, from OEM tweeter pods in A-pillars and sail panels to custom installations in kick panels, dash locations, or door-mounted configurations. Small size and low weight (enhanced by neodymium motor) further simplify mounting while improving acoustic performance.
The 25mm voice coil diameter and neodymium motor design ensure excellent thermal power handling despite the compact size. When properly filtered at the recommended minimum 2.5kHz crossover point, the X1 handles up to 120W of suggested power—far more than required for even high-output systems. The efficient motor design and integrated cooling through the tuned chamber prevent thermal compression during demanding playback, maintaining consistent performance.
Every aspect of the X1 motor and chamber design targets minimized resonance and distortion. The tuned polypropylene chamber reduces backwave reflections that color output, while the machined aluminum body provides rigid, non-resonant mounting. The 570Hz resonant frequency is exceptionally low for a tweeter, enabling use in two-way systems where the tweeter must handle lower midrange frequencies without strain—ideal for systems with 8" or 10" midbass drivers requiring lower crossover points.
The one-piece body and flange is precision-machined from 6061 aircraft-grade aluminum—not poured or cast. This manufacturing approach ensures the dense metal structure completely lacks the interstitial voids found in cast aluminum that cause unwanted resonances. The result is a tweeter body that remains inert during operation, refusing to add coloration or distortion to the output. The solid aluminum construction also provides exceptional durability and dimensional stability across temperature extremes.
The machined aluminum 47.5mm knurled attachment nut at the base of the tweeter provides optimized clamping strength to any mounting media—from factory tweeter pods to custom fiberglass or acrylic panels. The 3mm-larger-than-L1V2 mounting flange provides a solid-aluminum mounting surface without requiring mounting cups or external hardware. This integrated approach simplifies installation while ensuring rigid coupling between tweeter and mounting surface for optimal acoustic performance.
Nickel-plated spring-loaded push terminals integrated into the extruded polypropylene tuned chamber provide flexible connectivity options. These high-quality terminals accept large-gauge tinned wiring directly without requiring crimp terminals—simplifying installation and ensuring low-resistance connections. The spring-loaded design maintains consistent contact pressure over time despite thermal cycling and vehicle vibration, ensuring long-term reliability in demanding automotive environments.
The X1 shares dimensional design with the Legatia Pro, Pro SE, and Pro R2 for seamless upgrade potential. If you currently own L1 Pro or L1 Pro SE/R2 tweeters, the X1 drops directly into place without modification to mounting or wiring. This upgrade path allows existing Hybrid Audio users to experience the enhanced ring radiator topology and improved off-axis response of the X1 without fabrication work—simply swap tweeters and enjoy the performance improvement.
The X1 advances beyond the L1 Pro dome design with ring radiator geometry and proprietary wave guide engineering. This topology delivers more authoritative upper-range frequency response ability—six full octaves of information—with significantly improved off-axis performance. The ring radiator geometry combined with Hybrid Audio's proprietary wave guide prevents the phase cancellation and off-axis irregularities that plague conventional ring radiators, delivering uniform polar response critical for in-car applications.
Compared to the original L1 Pro, the X1 features lower inductance for improved high-frequency extension and transient response, while simultaneously achieving lower moving mass for better transient accuracy. This combination—typically a trade-off in tweeter design—results from advanced motor and diaphragm engineering. The slightly heavier moving mass than L1 Pro (without negatively affecting transient response) affords more damping character, reducing distortion and enhancing detail retrieval.
Nominal and thermal power handling has been improved over the original L1 Pro R2 transducer through enhanced motor cooling, voice coil design, and diaphragm material selection. The X1 handles very high power with proper filtering (120W suggested with crossover), while the diaphragm is much less susceptible to mechanical deformation than other designs. This robust power handling ensures the X1 remains composed during high-output playback without thermal compression or power compression affecting performance.
At 23mm mounting depth, the X1 is 4.5mm shallower than the L1 Pro R2 predecessor—already one of the shallowest tuned chamber tweeters available. This ultra-compact profile, combined with the small footprint from the neodymium motor, enables installation in locations where depth or space constraints would prevent use of larger tweeters. The shallow depth doesn't compromise performance; rather, it expands installation possibilities for achieving optimal acoustic placement without fabrication compromises.
The Legatia X1 is the tweeter of choice for IASCA, MECA, and international sound quality competitions—proven by Team Hybrid's consistent championship dominance. The combination of flat frequency response, exceptional polar response, low distortion, and fatigue-free tonal balance allows competitors to achieve the subjective listening scores and measurement excellence judges demand. Pair with Legatia X3 or X6 midranges and proper DSP tuning for podium-winning performance.
The 570Hz low resonance frequency enables the X1 to cross as low as 2.5kHz, making it ideal for sophisticated two-way active systems. Pair with high-quality 8" or 10" midbass drivers (like Unity U69-S or Legatia L8/L10 series) and use DSP active crossovers at 3-4kHz with precise phase alignment. This configuration delivers three-way-like performance with simplified installation—perfect for enthusiasts seeking reference sound quality without the complexity of three-way systems.
In three-way configurations, the X1 handles uppermost octaves with effortless precision. Cross the X1 at 5-8kHz using steep 24dB/octave slopes, allowing dedicated midrange drivers to handle the critical vocal range without upper-frequency burden. This division of labor enables each driver to operate in its optimal range—the hallmark of championship three-way systems. The X1's superior off-axis response ensures proper soundstage even when physical constraints prevent ideal on-axis aiming.
The X1's 23mm shallow depth and 58mm footprint fit virtually all factory tweeter locations, from A-pillar pods to dash-mounted locations to sail panel positions. The superior off-axis response compensates for the less-than-ideal aiming typical of OEM locations, while the wide bandwidth enables integration with factory midbass or aftermarket component replacements. For enthusiasts seeking maximum sound quality improvement with minimal fabrication, the X1 delivers reference-grade performance in factory locations.
Advanced builders creating custom kick panel or door-mounted installations benefit from the X1's shallow 23mm depth and exceptional polar response. Mount tweeters on-axis aimed at the listener for maximum detail and imaging precision, or angle them off-axis for wider soundstage—the proprietary wave guide ensures excellent performance regardless of orientation. The compact size, light weight, and integrated mounting system simplify fabrication while the ring radiator topology delivers the resolution and extension that custom builds demand.
For enthusiasts seeking home-audio-like fidelity in their vehicles, the X1 delivers the resolution, tonal balance, and fatigue-free character that defines true high-fidelity playback.
