The MD-S215 and MD-S218 subwoofers offer dual  
15" or 18" front-loaded transducers, respectively.  
Large centrally located vents with radiused  
terminations eliminate port turbulence and noise.  
Transducers feature technically advanced 4" voice  
coils assembled with proprietary high temperature  
adhesives, vented ceramic magnet assemblies and  
highly optimized motor design to provide high linear  
excursion, low power compression, flat frequency  
response and a very low distortion figure.
