The DSP9 is the second product to emerge from Meridian’s groundbreaking Extreme Engineering Programme; a result of years of investment and research at the extreme edge of audio design.
The DSP9 features Meridian’s Precision Sonic Transport which uses innovative techniques and processes which ensure the entire journey taken by an audio signal through a product maintains maximum sonic fidelity, so that the listener is immersed in authentic and realistic sound.
The sculpted lines of the DSP9 provide enhanced sonic benefits, as the curvature of the exterior minimises unwanted diffraction of the sound produced by the loudspeakers. The subsonic bass drivers are housed in an isolated cavity and this separation prevents the forces created inside the loudspeaker by the bass-drivers from interfering with the performance of the midrange driver and tweeter.
BESPOKE SIGNAL MAPPING
Meridian Bespoke Signal Mapping utilises digital signal processing to apply tailored crossover filters that are designed specifically for each configuration of drive units within a loudspeaker.
E3 BASS
Meridian E3 Bass uses specifically designed filters to expand, extend and enhance the low-frequency response of the loudspeaker.
FFA
FFA (Full Frequency Alignment) is a combination of digital filters and delays to correct the group-delay of a loudspeakers. It ensures that all frequencies reach the listener’s ear at the same time.
Q-SYNC
Meridian Q-Sync deploys Meridian's multiple “First In, First Out” buffering system which minimises jitter, ensuring perfect timing and improved clarity.
PRO-ACTIVE BASS
Meridian Pro-Active Bass protects the bass drivers from over-excursion, ensuring maximum bass output without damaging the drive units.
PRO-ACTIVE THERMAL
Meridian Pro-Active Thermal monitors the audio being sent to the mid-range drivers and tweeters and limits the overall volume of the loudspeaker if there is a risk of the drive units getting too hot.
TRUE TIME
True Time is Meridian's proprietary Apodising Filter that avoids pre-ringing and cleans up the effects of early filters, converting pre-echo to post-echo.
TRUE LINK
Meridian True Link is an encryption method for transferring high-definition digital audio over SPDIF connections. It allows secure movement of digital audio whilst ensuring that the SPDIF clock signal can be transmitted with minimum degradation.
FREE-Q
Meridian Free-Q is used to compensate for acoustic problems associated with specific loudspeaker placement conditions.
