Why the Rawrawk Quasar Guitar Cabinet is Different

Most guitar speaker cabinets follow the same story: they’re either copies of traditional designs or built around a particular amplifier, with very little science or innovation behind them. For decades, guitarists have accepted this “that’s just how it’s done” approach. At Rawrawk, we thought it was time to challenge that.

The Rawrawk Quasar wasn’t designed by chance or by recycling the past. Every detail was engineered with a clear purpose: better tone, better feel, and better reliability on stage. Here’s what makes it different.

Rawrawk Quasar Guitar Cabinet

A Unified Cabinet Body

Most cabinets are a patchwork of panels, screws, and nails. Each joint is a potential weak point, and over time, these small parts can loosen, rattle, or colour the sound.

The Rawrawk Quasar Guitar Cabinet is fully glued as a single structure. No screws, no nails. This creates a rigid, resonant-controlled body that behaves more like a musical instrument than a flat box. The result: less energy lost to rattles and vibrations, more energy dedicated to your sound.

Precision-Tuned Ports for a Bigger Sound

Closed-back and open-back cabinets each have their compromises. Closed-backs are punchy but can sound boxy, while open-backs breathe but often lose definition in the lows.

The Quasar uses carefully engineered ports to extend the bass response without making the tone muddy. These ports are tuned to the cabinet’s dimensions and the physics of the driver, so you get a fuller low-end that still stays tight and musical. In short: it sounds bigger than it looks.

Internal Bracing for Strength and Clarity

Thin walls or poorly supported panels flex when the speaker moves air. That flexing eats into definition and makes the cabinet less predictable at higher volumes.

Inside the Quasar, a custom bracing system keeps every panel locked in place. This doesn’t just make the cabinet tougher on the road—it raises the cabinet natural resonant frequencies making it feel more lively.

Air-Tight Construction

Most cabinets leak. Tiny gaps in assembly, screw holes, or poorly fitted back panels allow air to escape, which slows down the speaker cone’s return to its resting position.

The Quasar is completely air-tight, meaning the speaker cone can move out, return quickly, and be ready for the next note. This fast response translates directly into better definition and articulation, especially when playing fast, complex passages.

Internal Reflective Chamber

Most guitar cabinets either leave the inside completely empty or stuff it with foam and other damping materials. Both of those choices change how the speaker interacts with the air inside the box.

When you fill a cabinet with foam, you’re essentially creating thermal losses inside the air volume. The sound energy gets partially absorbed and turned into heat. Acoustically, this makes the cabinet behave as if it were slightly larger, which can extend the low-end response. That’s why studio monitors and hi-fi speakers often use heavy damping — they aim for smoothness and neutrality.

But a guitar cabinet is not a hi-fi speaker. The Quasar takes a different path: its internal chamber is highly reflective. The reflective quality is deliberate — the inside of the cabinet is painted and lightly varnished.

Crucially, this approach only works because the Quasar’s internal modes have been reduced as much as practically possible. The interlocking bracing system and the carefully selected internal dimensions minimise standing waves. Once those resonances are under control, the reflective chamber can safely contribute to the sound without adding unwanted boxiness.

By preserving controlled reflections inside, the sound that leaves the speaker cone is enriched by subtle delayed energy. The result is a cabinet that feels more alive, resonant, and harmonically rich.

Another advantage of a reflective chamber is that it doesn’t only feed the ports at their tuned low-frequency resonance. Because the interior surfaces encourage reflections, higher-frequency energy radiating through the ports is also facilitated. This contributes to the Quasar’s sense of size and spaciousness, making it feel bigger than its footprint and helping it spread sound more evenly across the stage.

In other words:

Foam damping gives you smoother bass, but flattens the life out of the mids and highs.
A reflective chamber + tuned ports give you punchy lows and a lively mid/high contribution that projects with character.

That’s why the Quasar doesn’t just sound powerful — it sounds three-dimensional.

6. Designed with Acoustics Software—not Guesswork

Here’s where Quasar truly breaks away from tradition. Its internal dimensions (X, Y, Z) weren’t chosen at random or copied from a vintage cabinet. They were calculated using wave-based acoustic software to reduce internal standing waves (resonances that create “peaks” and “dips” in tone).

By minimising these modes, the Quasar avoids the highly “coloured” sound many cabinets suffer from. What you get instead is a more natural, balanced response that lets the guitar and amp shine.

6. Built for Musicians, not for Tradition

Every decision in the Quasar came back to one principle: what actually makes a better cabinet?

Stronger and lightweight unified build for reliability.
Tuned ports for controlled low-end.
Internal bracing for higher resonant frequencies and clarity.
Air-tight design for fast, articulate response.
An internal reflective chamber.
Dimensions chosen with science, not nostalgia.

It’s not about looking vintage, and it’s not about copying what worked in the ’60s. It’s about giving players a cabinet that is light in weight, sounds bigger, clearer, and more defined, whether on stage or in the studio.
