The enclosure is pressure die-cast aluminium that maximises rigidity and lends it a unique form.

A new 50W + 50W bi-amplifier drives the transducers optimally while providing adequate headroom and dynamics. The maximum SPL measures in at an impressive 104dB.

The 4.5 inch CURV cone woofer produces impressive bass and transient response.

The silk dome tweeter is nested in a custom waveguide to produce on and off axis linearity and a wide, detailed soundstage.

On the front is a level control ranging from mute to +6dB with centre detent at 0dB.

The SRP 400 accepts XLR and TRS balanced inputs

Tapped inserts at the rear and bottom allow for various mounting options.

The SRP range is ideal for: Music producers Recording and mastering engineers Broadcast professionals Content creators Home studio enthusiasts Educational institutions and audio training centres
All SRP monitors are active speakers with built-in bi-amplification. Each driver has its own dedicated amplifier, ensuring precise crossover performance, improved dynamics and lower distortion
The pressure die-cast aluminium enclosure is significantly more rigid than conventional MDF cabinets. This reduces cabinet resonance and coloration, resulting in tighter bass, greater clarity and improved overall accuracy.
The custom-designed waveguide improves on-axis and off-axis response, creating a wider listening sweet spot with excellent stereo imaging and consistent tonal balance.
Absolutely. The SRP range is available in multiple sizes, making it suitable for compact home studios as well as larger professional control rooms.
No. Since every SRP monitor has built-in amplification, simply connect your audio interface, mixer or monitor controller using balanced XLR or TRS cables and you're ready to work.
For the best audio quality, it is recommended to connect the monitors through an external USB audio interface or mixer. This provides balanced outputs, better signal quality and lower noise.
Yes. The SRP monitors include acoustic tuning controls that allow you to adjust bass and treble response to compensate for room acoustics and speaker placement.
The right model depends on your workspace and application: Smaller models are ideal for desktop and compact studios. Mid-sized models offer greater bass extension for general music production. Larger models are suited for professional studios requiring higher SPL and extended low-frequency performance.
