Domestic hi-fi listening is dominated by reverberant rather than direct sound
Evidence
Clearly the level of the reverberant field is strongly affected by the level of average absorption. The first example would be typical of an extremely “dead” acoustic environment, as found in some studios, whereas the second is typical of an average living room. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1776 (

One more important acoustic property of a loudspeaker is its directivity pattern. In an anechoic room, we are only interested in the direct radiation to the listener, but in normal spaces with wall reflections and reverberation the listener receives all these delayed signal counterparts as well. In a relatively reverberant room, it is desirable to use a loudspeaker that has some directivity; that is, it radiates more sound along the main axis than in other directions, especially at middle to high frequencies. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 474 (
