Section 3.1 – In Your Room

Introduction

Thor’s Hammer is unmatched in its ability to reproduce the deepest portion of the 

bass region in any musical event. However, room acoustics and boundary interactions 

affect the sound of a loudspeaker to such a large degree that poor setup can seriously 

degrade your enjoyment of Thor’s Hammer. 

Therefore, we offer the following section, which will present some guidelines on 

room acoustics and their interactions with subwoofers. While we will also outline some 

guidelines on the setup of the Thor’s Hammer, we strongly suggest that you have your 

local Wilson Audio dealer perform the subwoofer’s setup and crossover settings - as 

well as the final “voicing” of your primary loudspeakers. If you are using Thor’s Ham-

mer with Wilson loudspeakers, our dealers are specially trained in setting up Wilson 

loudspeakers and will ensure that you realize the full value of your purchase. 

Section 3.2 – Room Acoustics and Subwoofers

Room Resonance

Resonance in listening rooms is generally caused by two sources:

• Structures within the listening room.

• The volume of air itself within the listening room.

Structural Resonance

Structural resonances are familiar to most people as buzzes and rattles, but this 

type of resonance usually only occurs at extremely high volume levels and is usually 

masked by the music. In many wood frame rooms the most common type of structural 

resonance problem is “booming” of walls and floors. You can test for these very easily
