MYRA 218S

DESCRIPTION

MYRA system is a complete solution for mid to large size touring 

application  and  high-end  fixed  installation.  MYRA  214L  is  a 

full range variable curvature 3-WAY line array module, MYRA 
218S is a direct radiating dual 18” subwoofer featuring custom-

designed, very long excursion B&C drivers. 

 Designed without compromise, the MYRA establishes a new 
reference for SPL to size ratio, directivity control, coherence 

and  ease  of  use.  It’s  the  result  of  an  extensive  three  year  R&D 

program started from scratch to address the challenges of rental 
companies, FOH  and tour sound engineers.

The FBT MYRA 218S is a reference dual 18” subwoofer featuring 

FEM  optimized  reflex-tuned  enclosure  and  one  of  the  best 

low frequency transducers that technology can offer today, 
neodymium magnet, 4’’ voice coil and a/-22mm linear 

excursion.

Combining accurate cabinet resonance study and ingenious 
port arrangement which is designed to dramatically reduce 
turbulence and eliminate non-linearity, MYRA 218S delivers 
substantial low frequency energy down to 25Hz, and can offer 
standard or cardioid directivity with suitable DSP preset and 
physical deployment.

The  cabinet  construction  typifies  FBT’s  signature  “made  in 

Italy” production philosophy, completely fabricated in-house 
using  machined premium Baltic birch and tour-ready weather 

resistant polyurea coating. A two-point rigging system is flush-

mounted into the cabinet, allowing the suspension of up to 12 
enclosures with a 4:1 safety factor. Trucking and handling are 

made easy by the six comfortable, ergonomically placed handles, 

along with optional removable heavy-duty casters. To facilitate 
quicker transport and deployment, 218S subwoofers are stacked 
three per vertical transport cart in a 0-degree collapsed position.
