Reference Monitor Loudspeaker 
JEM M7s Reference

Result of a 5 year quest to create the best performing
monitor platform ever.


 
 

· Exceptionally coherent
· Powerfull stereo imaging
·
Heavy inert cabinet
· Ultra low noise floor
· Extended low frequencies
· Neutral response
· Low compression design
· Large sweet spot
· Gentle High Definition
· True 8 Ohm system

   
 


The JEM M7s Reference benefits from the simplicity of the two-way with its mere one crossover point. The filter is designed for maximum driver integration and retention of dynamics. The system is also optimized for relative close proximity to walls and usability in the challenging acoustic environment of the modern living room.

A large chunk of the design focus was aimed at reducing harmonic and intermodulation distortions. Especially the latter being of special interest to two-ways. Multiple technologies have been employed so that the system is capable of unchanged undistorted music at higher play levels.

 
 






 

The Cabinet

A highly resistent and inert cabinet is the basis of any true high end loudspeaker system. The cabinet is made from solid hardwood. About 70% is Walnut taken from the oldest parts of the trunk for their dramatic grain patterns. The cabinets are designed and produced in-house. Improved facetting for smoother frequency response and powerful stereo imaging.


Components used  

All of the best materials are used. Almost all manufactured in Europe. A 6.9 inch Magnesium woofer with new specifications from SEAS in Norway and the latest much improved 25mm concave Corundum tweeter from Accuton in Germany form the moving heart of the system. The drivers receive the JEM RST® treatment to avoid harshness as so many times heard in high resolution systems. Specially selected Paper-in-Oil series capacitors, oil impregnated MKP caps and ultra quiet Jantzen Copper Foil inductors also contribute and make for a very black musical background and

 

 

high resolution but gentle laid back performance. Filters and drivers are all hard-wired and fixated with silver solder. Inner cables are silver plated OFC with a large (>35%) content of silver for constant crystal clear performance over the years.

Individual Tuning

In quality control every pair is measured and heard. When necessary individually tuned to compensate for any driver or filter component spec deviation. Plus user adjustable tweeter level in the most audiophile way with external Jantzen Superes resistor jumpers.

Contact

I demonstrate my loudspeakers in an environment where the chance of client judgement error is the lowest. A residential setting; my own living room. Because of this we do require appointments. Perhaps a little inconvenient but you will have an uninterrupted private session plus my full attention. In addition there are demonstration days throughout the year. I will put the dates in my blog (under construction) soon.
