Let’s face it, these frequencies do exist. 200 Hertz and below. Are they relevant to music? The answer is, of course, yes. Is music reproduction impossible without them? The answer is no. Many beautiful and legendary recordings have been made that barely tickle this frequency range, but if you like to take it to the limit, these units provide muscle and accuracy to fulfill the needs within these frequencies. A bit of trial and adjustment provides your regular playback system with a stunning and theatrical low frequency presence. In other words, a perfect pairing with Specimen Horns.
