Some years ago I was asked to visit Plattenwerk.at. They spoke about low frequency (LF) issues … The problem See the initial situation below: Simulation confirmed measured LF response abberations of the KH monitors at work, due to strong room interference. They liked the look of their room too much Weiterlesen…
Few loudspeakers achieve linear response and perfect step response with short signal path. Now include perfect phase at crossover and do it purely analog. Finally, add a few extras, again with very few additional analog parts, to adapt this system to the LF (low frequency) room characteristic to build an Weiterlesen…
Besides improving regular Haigner loudspeakers I work on room acoustics, custom loudspeaker designs and our app, TestHiFi. Custom horns range from large venue (old analog picture scan, sorry, but: 23 Hz @ 120 dB / W / m concrete horn casting mould) and midsize PA (picture courtesy DanubianDub) to domestic Weiterlesen…
