Manufacturer's Description from Dynaudio

Adding 18S to your monitors will open up a new world of performance that lets you mix and master with painstaking accuracy… and deliver tracks that translate beautifully to any playback system.


We’ve applied advanced DSP modelling technology that acoustically matches 18S to any Dynaudio Pro Studio Monitor from BM Classic, LYD and upwards, turning two-way systems into three-way set-ups. Its punch is delivered by two of our brand-new MSP+ Hybrid Drive units and a 500W amp for absolute control and power.


Getting the 18S to match seamlessly with our professional monitors is key for absolute accuracy when mixing and mastering. That has meant assessing the acoustic characteristics of each of our popular high-end studio speakers and creating custom performance maps for each one. And it’s future-proof: when we add new studio speakers to the line-up, we’ll release a firmware update for the 18S to add their performance maps – so it can grow along with your needs and equipment.


With this information at its disposal, the 18S’s display and menu system lets you select the specific Dynaudio speakers you’re using in your monitoring setup. This means the roll-off can be tailored perfectly to suit. And, if you combine a LYD 48 stereo or surround setup, you’ll essentially have a full-blown four-way monitoring system at your disposal.


The 18S has a selection of RCA or XLR connections for flexibility with your studio setup, and comes with a number of handy features to help more advanced systems too. This includes the ability to set a time delay to ensure the sub and speakers are working perfectly in sync: all you need to do is enter the distance from the sub to the speakers and the sub adjusts itself automatically using both time and phase delays.


There’s also a full three-filter parametric EQ to easily defeat room modes that could affect the accuracy of your final recording.



MSP+ Hybrid Drive

We’ve designed a brand-new driver for the 18S. This one is made from aluminium rather than our standard Magnesium Silicate Polymer material. It has paper backing and an MSP dust-cap on the front. Why the sandwich? Because a subwoofer requires a different balance between stiffness, lightness and damping than standard speaker drivers.


The new MSP+ Hybrid Drive units have been designed specifically with subwoofers in mind for the best performance possible. Adding 18S to your monitors will open up a new world of performance that lets you mix and master with painstaking accuracy… and deliver tracks that translate beautifully to any playback system.

Dynaudio Acoustics

About Manufacturer

The Vision A world where there is no difference between real / live sound and sound reproduced by a loudspeaker. A world where audio engineers, consumers, music-lovers and film viewers expects 100% accurate reproduction of sound - the perfect illusion with all the transparency, details and imaging we know from the real world. This is the vision of Dynaudio Acoustics - a world where you trust what you hear without even thinking about loudspeakers. The Mission Develop, innovate and manufacture state of the art monitors that can be trusted 100% by audio engineers and artists. Everything we do is centered at the artists that work with audio and demands transparent and accurate reproduction of sound - our customers. After all, it is the very same artists that in return give us productions and art that make it all worthwhile. We constantly challenge ourselves and innovate in search of further improvement and perfection of sound reproduction. Our customers Include some of the most demanding studios, engineers, producers and production environments throughout the world. We are proud of our customers and what they achieve. The Owl The great horned owl is known for its super hearing, sight for details, intelligence and precise judgement. Horned owls are active during night. They rely on and trust their ears 100% when navigating through the big woods searching for food. It is said that the great horned owl while in the air can hear small targets moving on the ground - they can also hear the exact distance and direction to the sound source. The ability to focus on, hear and judge the detail while working with the big picture is what makes working with audio an art. Engineers, like the great horned owl, must trust what they hear. Like the great horned owl, we believe that engineers deserve the freedom to navigate and judge the sound-scapes relying on their ears. That is the reason we have placed the Great Horned Owl in the centre of our Logo and that is the reason we build monitors that speak the truth - not more, not less.
