In the early 1980s, some performers began using two-way or three-way cabinets, with 15" woofers, a vented midrange driver and a horn/driver, with an audio crossover directing the signal to the appropriate driver. Folded-horn bass guitar rigs have remained rare due to their size and weight. As well, since the 1990s, most clubs have PA systems with subwoofers that can handle the low range of the bass guitar. The more common use of tweeters in traditional bass guitar amplifiers in the 1990s helped bassists to use effects and perform more soloistic playing styles, which emphasize the higher range of the instrument.
