One pair of Funktion One Bass Reflex BR121 in awesome condition, including wheels, M20 mounting plate and high quality custom protective covers.


There are some slight scuffs on some edges but these are only surface marks, however these scuffs will be fully refurbished and repainted with F1 Violet paint so the units will look almost brand new.


They are in full working order, sounding superb!

This new range of Bass Reflex enclosures from Funktion-One address applications requiring deep, strong bass at close range including clubs and high performance monitoring.  The unique tuning of these designs results in relatively compact size yet with more definition than is usually available from this type of enclosure.  This extra definition means they can also be used for higher bass frequencies, leading to use in a wide variety of configurations, extending Funktion-One systems by delivering plush elastic bass with plenty of low frequency extension.


BR121 / BR221 - Provides deep sub-bass extension from a single enclosure.  Well matched with products including F215Mk2, R2, R3 etc.
