Lineup comparison

We think it's helpful to understand how their products compare. To learn more about each, scroll to the section above to click through to individual product pages.

8.0 MINI ELLIPSE BOLLARD:  

  • Positioning: A compact outdoor 2-way speaker designed for flexible installations.  
  • Description: Offers a 6.5-inch woofer paired with a pivoting 1-inch titanium tweeter for efficient and discreet outdoor audio performance with a broad 120° dispersion angle. Compared to larger offerings in the lineup like the 3-Way Ellipse and Line Source, it provides a cost-effective solution ideal for small spaces and basic functionality needs.

CONTOUR:  

  • Positioning: The entry-level outdoor speaker that emphasizes versatile installation in various landscapes.  
  • Description: Features a custom coaxial driver with a fractal wave guide that improves efficiency in a compact one-piece composite enclosure. When compared to premium products such as the 3-Way Ellipse and Line Source, its design prioritizes ease of integration and affordability over higher power handling and advanced driver configurations.

PATHFINDER:  

  • Positioning: A mid-range, omni-directional outdoor speaker focused on installer-centric flexibility and complete outdoor coverage.  
  • Description: Uses a patented acoustic suspension system and a unique design with dual full-range drivers and passive radiators to deliver consistent 30W performance from a compact form. In contrast to the simplicity of Contour and the more driver-intensive setups of the Ellipse Bollards and Line Source, it is optimized for filling larger outdoor areas with balanced sound while maintaining flexible mounting options.

10.0 3-WAY ELLIPSE BOLLARD:  

  • Positioning: A premium outdoor 3-way speaker engineered for bi-amplified, full-range sound in demanding installations.  
  • Description: Integrates separate satellite and subwoofer sections with dedicated Hi-Pass and Lo-Pass filters to achieve refined frequency control and deeper bass response. Compared to the simpler 8.0 Mini Ellipse and entry-level Contour models, it offers enhanced performance with higher power handling and a more sophisticated multi-driver configuration.

LINE SOURCE:  

  • Positioning: A flagship, high-performance outdoor line array system designed for long throw distances and uncompromised fidelity.  
  • Description: Features groundbreaking variable waveguide technology and a proprietary four-layer laminar flow grill system that protect drivers and direct sound with exceptional clarity and volume. When compared to the localized dispersion of Bollard speakers like the 3-Way Ellipse and Mini Ellipse, it delivers superior sound coverage over extended distances, making it the top choice for demanding, large-scale outdoor environments.

About the brand

Aerial Acoustics creates speakers with cabinets made from multiple layers of pressure-bonded MDF and uses custom drivers with unique materials like papyrus-blend cones for their distinctive sound. Their speakers are particularly noted for their ability to "disappear" into the soundstage, creating a holographic listening experience that's rare among dynamic speakers.

About the brand

Perlisten Audio's speakers feature a unique Directivity Pattern Control array that combines a beryllium tweeter with thin-ply carbon diaphragm midrange drivers to control sound dispersion and enhance imaging precision, and they're the first brand to achieve THX Dominus certification. Their speakers use proprietary thin-ply carbon diaphragm material that's 30% lighter than standard carbon fiber, with their DPC array designed to minimize floor and ceiling reflections while maintaining precise horizontal soundstage.

Our interview with the brand

What are two key technological innovations or strong opinions that differ you from other brands?

As for as tech breakthroughs, we have our patented DPC array: a tweeter inside two midranges. This improves sensitivity and dynamics through such light drivers (3g or less).

Across our entire line, you’re getting 3D soundstaging, detail, dynamics, and low distortion. Most noticeable to the listener is the way sound propagates throughout the room: we focus on a wide dispersion left and right, and slightly limit it top to bottom to minimize first reflections on the floor and ceiling. This makes the speakers easier to place.

As you move up price in our line, the extent to which we do this passive beamforming on the vertical axis descends into a lower and lower frequency.

What other products pair best with yours?

Perlistens are generally not difficult to run. Take the S7t for example: High 80s, low 90s sensitivity. That can run with anything. But, because Perlistens can play so loud, they do like a lot of power to fully show off.

Two brands we generally pair Perlisten with: On the upper end is Audioflight from Italy. On the budget friendly end, Primare. But they've been paired with so much—we haven't come across a pairing they don't work with unless it's a 3W triode tube amp due to insufficient power.
