Sound colouration emerges from the combined loudspeaker and room properties

Evidence

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. The colouration of sound depends both on the loudspeaker and the room properties in a complex way. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 474
