The high resolution DSP730 architectural loudspeaker combines incredible performance within a compact design. It is perfectly suited to small and medium-sized room installations where performance is paramount.

Designed for easy and flexible installation the DSP730 delivers a maximum output of 115dB@1m and bass extension down to 38Hz. Its array of drive units includes a high performance beryllium tweeter for ultimate Hi-Res fidelity. It is capable of playing over 40kHz and has superb off axis performance enabling it to produce a uniform and lifelike stereo image over a wide listening area.

Where to Buy

Reference Series In-Wall


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. Grille 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 DSP730 joins the DSP750 in the Reference series, with both loudspeakers delivering Hi-Res audio and the very best in dynamics and clarity.
