08X + KA18 Short Throw 8" Coaxial PA Speaker System | Sinbosen
The 08X + KA18 is a compact, pole-mount sound system built for venues where space is tight and performance is not negotiable. A true point-source coaxial top with 100° axisymmetric dispersion sits atop a high-output 18-inch subwoofer, delivering full-range, concert-grade sound from a footprint that fits almost anywhere. No truss. No fly-ware. No heavy lifting — one person can set it up in under five minutes.

1.Points & Advantages of Pole-Mounting
Exceptional Phase Alignment & Acoustic Integration
Coaxial Advantage: The 08X features coaxial design, aligning high and low frequencies on a single axis with 100° axisymmetric directivity. This eliminates crossover interference in near-field applications.
Seamless Crossover: The 08X frequency response extends down to 60 Hz, while the KA18 dips down to 32 Hz. Driven by Sinbosen DSP amplified controllers (e.g., A-4X / A-12X1) with dedicated factory presets, vertical pole-alignment provides flawless crossover transition and impactful low-end extension.
Minimal Footprint & Clean Sightlines
Compact Footprint: Instead of deploying heavy trusses or rigging, the system relies on the KA18’s solid weight (~52 kg / 115 lbs) as a stable base, requiring only a simple mounting pole.
Low Visual Intrusion: Weighing just 12 kg (26.5 lbs), the 08X is sleek and unobtrusive. It elevates the sound above the crowd without blocking LED screens, stage sightlines, or event backdrops.
Quick & Easy "Plug-and-Play" Setup
Single-Person Deployment: Simply screw an M20/35mm pole into the KA18 top mount and slide the 08X onto the pole. The entire system can be set up by one technician in under 5 minutes without fly-ware or heavy lifting gear.
Adjustable Height: The pole height can be quickly adjusted based on seated or standing audiences, ensuring high-frequency clarity passes over front-row heads to cover the full depth of the venue.
High Output Relative to Size
Despite its compact 8-inch enclosure, the 08X delivers a maximum SPL of 129 dB, while the SB18 produces up to 136 dB. This combination delivers concert-level clarity and dynamic headroom from a remarkably small footprint.
2. Typical Use Cases
|
Application / Scenario
|
Why Choose the 08X + KA18 Pole Mount?
|
|
Corporate Events & Product Launches
|
Crystal-clear speech intelligibility paired with premium background music playback—all while maintaining an elegant,
non-intrusive aesthetic. |
|
High-End Weddings & Private Parties
|
Covers everything from background lounge music and speeches to high-energy DJ sets and live band performances.
|
|
Small Livehouses & Jazz Clubs
|
Delivers "Concert Sound" warmth and detail, ideal for acoustic, jazz, pop, and intimate vocal performances.
|
|
Touring / Large Stage Fill
|
Acts as a high-fidelity side-fill, front-fill, or DJ monitor on larger concert stages.
|
|
Multi-Purpose Halls & Auditoriums
|
Perfect for temporary setups where ceiling rigging is not available, offering easy tear-down without damaging interior decor.
|
3. Coverage Capacity & Scale
Audience Size: A single stereo pair (1× 08X + 1× KA18 per side) comfortably covers 150 to 400 people in indoor or small outdoor settings.
Throw Distance:
Primary Coverage: 10 to 20 meters (~30 to 65 ft). The 100° point-source dispersion retains pristine high-frequency detail within this range.
For deeper venues (>20–25 meters), adding 08X delay speakers or upgrading to a line source system (e.g., Ka208/KA10/KA15) is recommended.
