System for reducing response anomalies in an acoustic pathway

An acoustic system comprising:

• an acoustic assembly including:
• a waveguide having a throat aligned along a first axis;
• a tube having a first end and a second end, wherein the first end is removably attached to the throat;
• and
• a compression driver having an output opening aligned along a second axis, wherein the second end of the tube is removably attached to the output opening;
• and
• a sound system configured to send an audio signal to the acoustic assembly for generating a sound wave, wherein the sound system includes a processor including a finite impulse response (FIR) filter, wherein the FIR filter includes a filter length based on an impulse response of the acoustic assembly to cancel one or more major reflections occurring within the acoustic assembly.

An acoustic system comprising:

• an acoustic assembly including:
• a deflector;
• a tube removably attached to the deflector;
• and
• a compression driver removably attached to the tube, wherein the tube and the compression driver are aligned along a common axis;
• and
• a sound system configured to send an audio signal to the acoustic assembly for generating a sound wave, wherein the sound system includes a processor including a finite impulse response (FIR) filter, wherein the FIR filter includes a filter length based on an impulse response of the acoustic assembly for canceling out one or more major reflections occurring within the acoustic assembly.

A method for operating an acoustic system that includes a sound system in communication with an acoustic assembly, the method comprising the steps of:

• in the sound system,
• sending a digital signal to a finite impulse response (FIR) filter;
• filtering the digital signal in the FIR filter according to a filter length that is based on an impulse response of the acoustic assembly to provide a filtered digital signal, wherein the impulse response of the acoustic assembly includes a direct portion, a tail portion, and one or more major reflections occurring within the acoustic assembly, wherein the filter length is set to at least cover a first major reflection of the one or more major reflections occurring within the acoustic assembly such that the FIR filter at least cancels out the first major reflection;
• converting the filtered digital signal to an analog signal in a DAC;
• amplifying the analog signal in an amplifier to provide an amplified analog signal;
• sending the amplified analog signal from the sound system to the acoustic assembly;
• and
• in the acoustic assembly,
• generating a sound wave in response to the amplified analog signal, and
• transitioning the sound wave from traveling in a first direction to traveling in a second direction.
