Genius Audio's powerful line of GFD-135 amplifiers was designed to offer the same sound quality as the ones of A class amplifiers and the efficiency of D class ones. With very careful selection of high quality SMD electronic components, transformers that offer power stability, and a high-density heat sink. It also comes with a professional generation crossover, allowing to greatly raise the frequencies selected under both the HPF and LPF features (from 20 Hz up to 4000 kHz for HPF, and from 40 Hz up to 4000 kHz for LPF), allowing to manage the cutoff frequency of most speakers.
