The class-leading DSP750 is Meridian’s highest performing architectural loudspeaker.

Engineered using Meridian’s, core principles of acoustic design, the DSP750 delivers high-resolution audio that is perfect for architectural installations and dedicated home theatres.

Featuring all-new drive-units, including a beryllium tweeter, the DSP750 produces a natural and lifelike sound with high fidelity and perfect tonal balance. Its high dynamic range, incredibly low distortion, and outstanding signal-to-noise ratio combine to provide full-range audio with exceptional headroom and low listener-fatigue.

Where to buy

Reference Series In-Wall


With a host of exclusive Meridian technologies on-board, the DSP750 resets the standard of architectural loudspeaker performance. Ultra-shallow (100mm deep) design provides full DSP loudspeaker performance, while the rough-in box and frame system allows for easy installation and precise positioning. Grill can be painted to match décor.

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.

Image Elevation

Image Elevation psychoacoustically raises the sound image to the centre of a screen – where the listener would expect to hear it from.


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.

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.


Meridian's HPA (High Powered Array) processing technology minimises destructive interference between the multiple loudspeakers when used in an array configuration.

Architectural Reference Range

Our Architectural loudspeakers incorporate resolution enhancing technologies for the ultimate listening experience in a large range of installation applications.The DSP750 is joined by the DSP730 in the Reference series, with both loudspeakers delivering Hi-Res audio and the very best in dynamics and clarity.
