NB!


Previously owned in good condition with minimal scratching. SOLD AS A PAIR! R52000 Great deal for Bi-Amping or Bridged Monoblock mode!

Upgraded fuses: External fuses have been upgraded to German HiFi Tuning Fuses (5 behind each Amp). Internal fuses have been upgraded to Japanese Furutech Light-Blue Fuses (4 in each Amp)
