In recent years there has been much debate about how effective equalization is in reducing the negative impact of room modes. Room modes are characterized by a peak in the frequency response and extended ringing in the time domain.

This weeks blog posts covers some of my favorite disks that I use when I am out at a customer's house diagnosing their room's unique acoustical issues or setting up their system. They have been chosen because they are high quality recordings that contain elements that are useful to test a system's sound quality.

This article continues the theme of the last two blog postings in whic we outlined some ways in which subwoofers can be used to improve sound quality. This week we introduce the Welti / Devantier and Geddes multi-sub methodologies. Both involve using multiple subwoofers as a way to smooth bass response and reduce the impact of modal resonances.

Deep nulls in the frequency response in the bass region can be caused by phase cancellation between the direct sound wave from a sound producing device and the indirect sound wave that has reflected from a nearby boundary such as the floor, ceiling or walls. This phenomenon is called speaker boundary interference or SBIR for short. This article introduces SBIR and explains how these deep nulls can be ameliorated through use of a subwoofer.
