from the US to get more of a bass reflex sound that suited local tone preferences for dancehall audiences, as the unmodified folded horn was found to be "too aggressive" sounding and "not deep enough for Jamaican listeners". In sound system culture, there are both "low and high bass bins" in "towering piles" that are "delivered in large trucks" and set up by a crew of "box boys", and then positioned and adjusted by the sound engineer in a process known as "stringing up", all to create the "sound of reggae music you can literally feel as it comes off these big speakers". Sound system crews hold 'sound clash' competitions, where each sound system is set up and then the two crews try to outdo each other, both in terms of loudness and the "bass it produced". In the 1980s, the Bose Acoustimass AM-5 became a popular subwoofer and small high-range satellite speaker system for home listening. Steve Feinstein stated that with the AM-5, the system's "appearance mattered as much as, if not more than, great sound" to consumers of this era, as it was considered to be a "cool" look. The success of the AM-5 led to other makers launching subwoofer-satellite speaker systems, including Boston Acoustics Sub Sat 6 and 7, and the Cambridge SoundWorks Ensemble systems (by Kloss). Claims that these sub-satellite systems showed manufacturers and designers that home theater systems with a hidden subwoofer could be "feasible and workable in a normal living room" for mainstream consumers. Despite criticism of the AM-5 from audio experts, regarding a lack of bass range below 60 Hz, an "acoustic hole" in the 120 to 200 Hz range and a lack of upper range above 13 kHz for the satellites, the AM-5 system represented 30% of the US speaker market in the early 1990s. In the 1980s, Origin Acoustics developed the first residential in-wall subwoofer named Composer. It used an aluminum 10-inch (25.4 cm) driver and a foam-lined enclosure designed to be mounted directly into wall studs during the construction of a new home. The frequency response for the Composer is 30 to 250 Hz. 1990s to 2010s While in the 1960s and 1970s deep bass speakers were once an exotic commodity owned by audiophiles, by the mid-1990s they were much more popular and widely used, with different sizes and capabilities of sound output.
