Our new RCF HDL-20 line array system is built for events that need cleaner projection, more professional coverage, and a scalable deployment format. Whether your show calls for a compact ground-stacked system or a properly flown concert rig, Eden USA can configure the system around your audience size, venue conditions, and bass expectations.
If you are planning a concert, festival, corporate event, school production, worship service, or premium DJ event, this page will help you explore whether a ground-stacked or flown HDL-20 configuration may be the better fit for your audience size, venue layout, and bass expectations.
A line array format helps project more evenly across deeper audience areas than many basic left-right speaker systems.
The system can be configured for smaller premium events, medium outdoor shows, and larger concert-style productions.
Depending on the site, the rig can often be built as a clean ground stack or as a flown line array for larger coverage needs.
We can scale the low end based on whether your event is speech-focused, full-range musical, or built for serious impact.
This is often the best option when the venue does not support flying the PA, when the audience area is moderate, or when fast deployment matters. It is a strong choice for schools, community events, worship gatherings, corporate programs, and many medium-size outdoor events.
A flown HDL-20 line array is often the stronger solution for larger audiences, longer throw, cleaner sight lines, and more controlled coverage. A venue does not always need its own built-in fly infrastructure for this to be possible. Eden USA also owns a pair of premium Sumner Eventer 25 crank tower lifts, which can be deployed on qualifying events to support flown line-array configurations even when the venue does not provide its own roof or truss fly points.
As long as the site provides enough vertical clearance for the array to work effectively, a flown system can often deliver a more polished and better-controlled result than a ground-stacked approach. In general, we look for at least 10 feet of usable vertical clearance before recommending a flown line-array configuration.
Answer a few practical questions and get a starting recommendation for array format, boxes per side, and approximate subwoofer quantity.
The smart configuration tool below provides an approximate starting recommendation only. Final system size, flying suitability, and subwoofer count will still depend on venue layout, rigging availability, trim height, audience geometry, local noise restrictions, and event goals.
A great fit for outdoor stages, community concerts, music showcases, and festival-style coverage where stronger projection and scalable bass are important.
For premium presentations and entertainment segments where appearance, clarity, and controlled audience coverage all matter.
Useful where speech intelligibility matters but the event also benefits from musical support, performance reinforcement, or a more polished production standard.
We can finalize the right line array and subwoofer configuration once we know the venue, audience layout, event type, rigging conditions, and performance expectations.
A line array is often the better choice when your event has a deeper audience area, a wider crowd footprint, higher output expectations, or a more demanding production standard than a basic point-source system can comfortably handle. It is especially useful for concerts, festivals, worship events, school productions, corporate entertainment, and premium DJ events where smoother long-throw coverage and a more polished presentation are important.
Not always. If the venue already has proper rigging, roof support, or truss fly capability, that can certainly help. However, Eden USA also owns a pair of high-end Sumner Eventer 25 crank tower lifts that can support qualifying flown line-array configurations even when the venue does not provide its own built-in fly infrastructure. Final suitability still depends on clearance, layout, access, and safe deployment conditions.
As a practical starting point, we generally look for at least 10 feet of usable vertical clearance before recommending a flown HDL-20 configuration. More height is often better, especially when the audience is deeper, the coverage needs are more complex, or the show requires a more refined aiming angle. Final recommendations depend on the specific site, the audience geometry, and safe deployment constraints.
That depends on the audience size, throw distance, event type, and how much low-end impact you want. Smaller premium events may only need a few boxes per side and a light subwoofer package, while larger concerts or outdoor events can require more array elements and significantly more subwoofer support. The smart configuration tool on this page is meant to provide a fast approximate starting point, and our team can then refine the final package around your actual venue and production goals.
Yes. The HDL-20 system is a strong choice for both DJ playback and live music applications when the event calls for more output, better projection, and a more professional presentation than a small conventional speaker system. We can scale the subwoofer package, control package, monitors, microphones, and related support gear to match the type of show you are producing.
Yes. Eden USA can provide delivery, setup, safe deployment, tuning, operation support when needed, and post-event strike. For more advanced productions, we can also provide related sound-system components such as subwoofers, monitors, digital consoles, microphones, wireless systems, stage infrastructure, lighting, and technical crew support.
We provide line array and professional sound-system rentals throughout most of Southern California and surrounding event markets, including Los Angeles, Orange County, Riverside County, San Bernardino County, San Diego County, Ventura County, the Inland Empire, and Las Vegas. If your event falls outside those normal service areas, contact us and we can review travel and logistics options.
