Compact Active Reference Performance | Available at Trimira Audio
The JL Audio Primacy® S3 is a compact active loudspeaker designed to bring sophisticated DSP-controlled amplification and active crossover technology into a smaller two-way enclosure.
Rather than relying on a conventional passive crossover, the Primacy S3 uses dedicated internal amplification for its high- and low-frequency drivers, with onboard DSP managing crossover behaviour, driver alignment, and acoustic adjustment.
At Trimira Audio, we recommend the Primacy S3 for high-performance two-channel systems, desktop reference applications, compact listening rooms, and discreet home-theatre installations where active loudspeaker architecture is desirable.
Key Features & Technological Innovations
Fully Active 2-Way Architecture
The Primacy S3 uses an active two-way design, with the amplifier channels directly driving the individual acoustic sections.
The active architecture provides greater control over the relationship between the drivers than a conventional passive crossover arrangement.
Internal Bi-Amplification
Dedicated high-current amplifier channels are assigned independently to:
- High-frequency tweeter
- Mid-bass driver
This allows each transducer to receive its own amplification channel and enables the DSP to optimise the complete electro-acoustic system.
High-Precision Onboard DSP
The integrated DSP manages critical loudspeaker functions including:
- Active crossover filtering
- Driver time alignment
- Phase alignment
- Boundary equalisation
- Acoustic-response adjustment
This allows the speaker to be configured for its particular room and placement.
Custom Electro-Acoustic Drivers
The Primacy S3 combines a low-distortion mid-bass driver with a wide-dispersion high-frequency tweeter, designed to operate as a cohesive active system.
The direct amplification and DSP architecture allow the drivers to be individually controlled.
Acoustically Inert Sealed Enclosure
The compact cabinet uses high-density construction and internal bracing to reduce unwanted structural vibration and cabinet resonance.
The sealed enclosure architecture also provides a controlled acoustic foundation for the DSP-managed driver system.

Active System Architecture
The Primacy S3 is designed as a complete active loudspeaker rather than a conventional passive speaker requiring an external power amplifier.
The basic signal architecture is:
Digital / Analogue Source → DSP → Active Crossover → Dedicated Amplification → Tweeter & Mid-Bass Driver
This allows crossover behaviour, driver timing, phase, and boundary-response adjustments to be managed within the loudspeaker system.
Ideal Applications
The compact active architecture makes the Primacy S3 particularly suitable for:
- High-performance two-channel listening
- Desktop reference systems
- Compact listening rooms
- Nearfield monitoring
- Discreet home cinema
- Architecturally sensitive installations
Its integrated amplification also reduces the number of external system components required.
