With the availability of low-cost, PC-based acoustic data acquisition systems, experienced hobbyists can make highly accurate loudspeaker frequency-response measurements without an anechoic chamber. Popular systems include: Audiomatica's CLIO, MLSSA, Praxis (now part of the Dayton Audio OmniMic measurement bundle, available through Parts Express and Dayton Audio), and SoundEasy (also available though Parts Express), to name a few. The power of these systems comes at a price. These systems window the time-domain measurement to eliminate room reflections. This, in turn, limits low-frequency response.
Typically, response below 200 to 300 Hz is not possible in reasonably sized rooms.
