Sound Performance Lab (SPL) is based in Niederkrüchten, in North Rhine-Westphalia, Germany, and has manufactured professional and home audio gear since 1983. With a deep background in studio mastering, SPL founder and chief designer Wolfgang Neumann got the idea of starting his own company while managing a recording studio in rural Germany in the late 1970s. In those days, the US dollar was valued at roughly 3.5 times the deutschmark, and importing US-made studio gear wasn’t cheap. This led Neumann to begin the tinkering that ultimately convinced him he could design and build better-sounding products and sell them at prices significantly below those of imported US equivalents. By 1983, he’d begun selling his products under the SPL brand, but struggled with distribution until, in 1985, he met Hermann Gier.
