I have considered the IB configuration for some time. Does an IB system reduce room placement problems associated with sealed or ported configurations?

IB’s are the same concerning placement to avoid room modes as any sub is. Ported subs may have some other subtle problems in addition to this.

No. IB is subject to the same room interaction as any other subwoofer. The primary advantage of the IB is the lack of an air spring behind the woofers acting as a low pass filter. This allows the woofers to achieve high output with less power and eq, thus, in theory, lower distortion and higher performance.

Bass interacts with your room regardless of how it is reproduced.

Corner placement is not always the best, but is usually where you will find the greatest gain for the lower frequencies. Placement of an IB is *ideally done the same as for a boxed sub, but obviously ideal locations are not always available for this type of design.
