Sound Characteristics 

• Tight and controlled bass 
  
• Excellent soundstage depth 
• Coherent midrange and treble 

Note: This speaker can be positioned away from the front wall. (It should not be placed in the corner) The cabinet is shaped to reduce internal standing waves in the critical 300Hz-600Hz region where most square enclosures fail. 

Speaker system No.1815 features very high sensitivity for those using low power tube amplification. This design utilized a 15” woofer from SB Acoustics which does extremely well in a sealed enclosure. The result is clean and articulate bass. 

Rated at 95dB sensitivity (anechoic) or 102dB (in-room), providing bass extension flat to 50Hz (40Hz F6) in a compact form factor.
