Eminence LAWG10 Line Array Horn
Best for: venues needing wide horizontal coverage with reliable bolt-on compatibility. The LAWG10 delivers a 140° x 15° dispersion, ideal for tight-fitting line array systems where you want smooth high-frequency reproduction across a broad stage or audience area. The design aligns with 1″ exit bolt-on compression drivers, providing clean, transparent highs when paired with compatible drivers. Limitations include relying on a suitable crossover and compatible drivers to realize its full potential.
Why it was selected
- Wide dispersion supports even coverage in rectangular venues.
- Compact, bolt-on design simplifies installation with existing hardware.
- Clear high-frequency response helps reduce hot spots near the front row.
Best used for
Professional systems where installers want predictable horizontal coverage without complex aiming. It pairs well with a matching 1″ exit driver for clean highs across the venue.
Caution
Ensure the driver and crossover are compatible to avoid mismatched frequency response or unintended dispersion anomalies.
LASE 12.75″ x 6.6″ Dual 1.4″ Line Array Horn
Best for: mid-range and tweeter-frequency applications requiring a robust, long-throw line array horn. The dual 1.4″ throat configuration supports precise high-frequency focus while maintaining a compact footprint. This horn is suited for systems needing controlled vertical dispersion and extended reach in larger rooms or outdoor stages.
Why it was selected
- Long-throw capability helps reach rear audience areas with clarity.
- Balanced design supports smooth, natural highs without harshness.
Best used for
Installations where a balance of throw and precision is essential, such as mid-sized halls or outdoor stages with moderate audience depth.
Caution
Verify mounting compatibility with your existing compression driver and cabinet dimensions to ensure a proper fit.
LASE 12″ x 6″ Dual 1.4″ Line Array Horn Long Throw
Best for: long-throw line array systems that demand consistent high-frequency output across a wide audience. The 12″ x 6″ form factor with a 1.4″ throat supports strong mid-to-high-frequency performance while maintaining a compact package for stacking and mounting versatility.
Why it was selected
- Long throw enables front-to-back intelligibility at larger venues.
- Compact size facilitates convenient integration in standard line array builds.
Best used for
Installations emphasizing projection to rear seating areas without sacrificing vocal clarity or detail in the highs.
Caution
Careful alignment is needed to avoid phase issues between adjacent elements in dense line arrays.
LASE 8″ x 4.5″ Dual 1 3/8″ Screw-On Line Array Horn
Best for: compact line array setups needing a solid high-frequency extension. The 8″ x 4.5″ dual throat design is screw-on with a 2″ to 1 3/8″ adapter compatibility, making it flexible for various compression drivers. Ideal for smaller venues or stage monitors requiring tight vertical dispersion without losing HF clarity.
Why it was selected
- Smaller footprint with reliable high-frequency control.
- Versatile mounting options via screw-on interface.
Best used for
Small-to-medium rooms where space is limited but you still need crisp highs with controlled dispersion.
Startbuymore Line Array Waveguide for Pro Audio
Best for: a budget-friendly waveguide that offers optimized sound projection for line array systems. The 87x109mm dimensions are designed to provide precise mounting for compression drivers and tweeters while maintaining a stable, predictable output across listening areas.
Why it was selected
- Precise mounting design reduces vibration and improves stability during loud playback.
- Plastic construction delivers durability with a lightweight profile.
Best used for
Systems where a cost-effective, straightforward upgrade to horn loading is desired without sacrificing directional control.
Caution
Check the exact driver throat size and mounting pattern to ensure a secure fit and optimal alignment with your cabinet.
Buying Guide
What to look for when choosing a line array waveguide horn
- Dispersion pattern: Consider venues and seating layouts. Wider horizontal dispersion helps with even coverage, while specific vertical patterns focus energy where listeners are seated.
- Driver compatibility: Confirm throat size (commonly 1″ or 2″), mounting type (bolt-on, screw-on), and the system’s crossover design to ensure clean highs without phase anomalies.
- Build quality: Aluminum and high-grade plastics offer durability under transport and stage use. Weight matters for installation and rigging.
- Throw distance: Long-throw horns support rear seating areas; short-throw designs suit intimate spaces. Select based on venue dimensions and audience depth.
- Ease of installation: Look for compatible mounting hardware and simple, repeatable alignment to minimize setup time.
FAQ
- What is a line array waveguide horn?
Answer: It is a horn-shaped accessory that shapes and directs high-frequency energy from line array drivers, improving coverage and reducing dispersion losses. - How do I know which horn matches my driver?
Answer: Check throat size, mounting type, and compatibility with your compression drivers and cabinet dimensions. - Can I use plastic horns for professional venues?
Answer: Yes, but ensure durability and mounting stability; aluminum horns generally offer higher rigidity and heat dissipation. - Is wider dispersion always better?
Answer: Not always; it depends on room acoustics and seating. Too-wide dispersion may create diffuse sound in small rooms. - Do waveguides affect high-frequency response significantly?
Answer: Yes, they concentrate and shape HF energy, improving intelligibility and reducing off-axis coloration. - What maintenance is required for line array horns?
Answer: Periodic inspection for cracks, secure mounting, and ensuring no debris blocks the horn aperture.
