Perfectly matched* active studio monitors

Handmade with passion in Switzerland

What studio monitor is best suited for me?

All PSI Audio monitors have similar frequency and phase response and therefore can be mixed and matched in any multichannel system.

The advantages of a bigger monitor compared to a smaller one are the following:

  • More powerful with higher sound pressure level output
  • Lower frequencies can be reached
  • Higher accuracy with tighter tolerances

So the choice of one monitor over another should be made taking into consideration:

  • Listening distance
  • Desired bandwidth
  • Accuracy of monitor

Measurement Protocol

Measurement protocol for active monitors - Environment: anechoic room, temperature: 23 ± 2 °C
- LEVEL and ROLL-OFF on CAL position
- Mains power supply: 230 ± 2 % Vac
 
Data[Unit]Input signalDescription
Potential peak power[W]Hann-burst of 1 cycle Frequency: middle of the bandwidth emitted by the driver in question Amplifier without limiter with dummy load resistors of the same resistance as a the nominal impedance. The squared peak output tension is divided by the resistance value to give the potential peak power.
Continuous max SPL@1m[dB]PSI-M weighted noise* Level:
Limiter led flashing +6 dB
The maximum SPL @ 1m on axis is retained in RMS with a time constant of 250 ms (fast).
Short term max. SPL@1m[dB]PSI-M weighted noise** 25 % Level: Limiter led flashing +6 dBThe maximum SPL @ 1m on axis is retained in RMS with a time constant of 35 ms (250db/s).
Peak max. SPL@1m[dB]PSI-M weighted noise** 25 % Level: Limiter led flashing +6 dBThe absolute value (positive or negative) of the instantaneous peak SPL @ 1m on axis is retained.
Signal to noise ratio (S/N) The signal to noise ratio is the difference between the continuous max SPL @ 1m and the background noise @ 1m.
Bandwidth at -6dB[Hz]sine sweep 10Hz-40KHzThe bandwidth is measured at 90dB @ 1m on axis in between the lowest frequency and the highest frequency crossing 84 dB.
SPL tolerances[dB]sine sweep 10Hz-40KHzThe SPL tolerances are the admissible variations in dB of the frequency response within the announced bandwidth.
System[Nb of ways]Number of drivers with different bandwidths.
Crossover frequency[Hz]Frequency at which both drivers have identical SPL (typically -6 dB).
Woofer ext. diam.[mm]The dimension is the diameter of the circle circumscribed around the transducer overall.
Woofer ext. diam.[in.]The dimension is the diameter of the circle circumscribed around the transducer overall.
Dimensions W x H x D[mm]The dimension of the cabinet without connectors, grilles, brackets, etc.
Dimensions W x H x D[in.]The dimension of the cabinet without connectors, grilles, brackets, etc.

Quiescent consumption[W]Same as above but with no phantom voltage.
RMS continuous consumption[W]PSI-M weighted noise*Level:
Limiter led flashing +6 dB
RMS electrical consumption measured during the signal reproduction.
* PSI-M weighted noisePink noise with statistical music weighting
** PSI-M weighted noise 25 %PSI-M weighted noise with pulsations 2.5 second ON 7.5 seconds OFF
*** Origin of SPLIs the point beyond which the attenuation is proportional to the distance. This is determined by measuring the distance corresponding to 6 dB attenuation and subtracting this distance from the distance of the measurement point.

* with how much time and effort we invest in developing, designing and building our products, you can expect them to be very coherent across the whole range. Transfer functions both in frequency and phase are immaculate. As a result, we do not match pairs of speakers – all our speakers are matched pairs.

This coherence even goes across models, so combining differently sized speakers in a surround setup, for example, will still achieve a homogenous sound image.
