Testing Process:
Our speaker evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, dented tweeter domes, and cone damage. We also inspect the speaker connection points for loose or broken connectors.

After the initial visual inspection we connect the speakers to a reference amplifier with our preferred test tracks. With the speakers placed with proper distance we listen to each driver to make sure that they are producing the intended frequencies with no signs of distortion or rattle.

During listening tests with test tracks we check for proper stereo imaging and bass response at various listening levels. If there are any audible signs of issues, the speakers are taken to the bench where we perform a frequency sweep to isolate the issue so that it can be resolved by component repair or replacement.

Our subwoofer evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, cone damage, or rubbing voice coils. We also inspect the input connections for damage.

After the initial visual inspection we connect the sub at our bench and perform a sine wave sweep from about 200 Hz down to around 10 Hz. During this sweep we are listening for excessive rattle or other signs of improper function.

If the sweep passes we then increase the input level to evaluate how the woofer performs at high output levels. If the woofer has built-in crossover adjustments or multiple connection options these features are tested at this time.

We complete the subwoofer evaluation by feeding the unit with an audio signal in conjunction with our house music system to see how it responds to low frequency content in real world conditions while paired with a full range system.
