HIGHLINE™ A Player-Facing Amplifier Experience

More Info/Specifications

Traditional horizontal cabinets disperse sound unevenly, often forcing players to rely on monitors, tilt-backs, or guesswork. Highline changes that physics.

  • A vertical speaker array:
  • Places critical frequencies at ear level
  • Reduces beaminess and floor coupling
  • Delivers a more coherent, room-filling sound
  • Preserves feel and dynamics at real-world stage volumes

The result is a more immersive, controlled, and inspiring playing experience — whether on stage, in the studio, or at home.

The Highline Platform
Highline™ is a modular enclosure platform offered in three distinct configurations, each engineered to deliver a unique balance of punch, clarity, and dimensionality.

Highline 212
A focused yet expansive vertical 2×12 design that delivers classic authority with enhanced articulation and player-facing presence.

Highline 310
A powerful vertical 3×10 configuration that combines fast transient response with surprising low-end depth and room coverage.

Highline 10 + 15
A hybrid vertical system pairing the immediacy of a 10″ speaker with the depth and bloom of a 15″ — delivering exceptional dimensionality and harmonic complexity.
Each Highline enclosure is tuned to maintain balance, phase coherence, and feel across the full frequency range.

Designed for the Player
Highline enclosures are intentionally tall and compact, placing the sound where your ears and hands live. The experience is immediate, inspiring, and confidence‑building.

Players don’t describe Highline as louder.

They describe it as present, connected, and alive.

Available with 3rd Power Amplifiers
Highline™ vertical enclosures are available with select 3rd Power amplifiers, including:

  • Lyra
  • Aurora 35

Additional models and configurations will be introduced as the Highline platform expands.

Built Like an Instrument
As with every 3rd Power creation, Highline enclosures are built with the same care, precision, and intention as the amplifiers they support, designed not as accessories, but as integral parts of the instrument.

Highline is the missing link between your hands, your amplifier, and the room.

“Highline was created so players could finally hear and feel what their amplifier is truly doing, without compromise.”
-Dylana Nova Scott, Founder & Designer

Stand inside of your tone.

For decades, guitar amplification has been designed to project sound past the player, toward the audience, the room, or the back wall of a stage. Highline™ rethinks that relationship entirely.

Highline is a vertical enclosure platform designed to place the sound field where it matters most: around the player. By elevating and aligning the speakers vertically, Highline surrounds you with clarity, depth, and dynamic response, allowing you to stand inside your tone rather than chasing it.

This is not a new cabinet size. It is a new way to experience your amplifier.
