While
CrossoverShop contains all of the features and parameters necessary to compute
the response of a system with very high accuracy, there are limiting factors
which will always produce some differences between the simulation and the
actual results. The calculation of a crossover system involves many elements
and data. Some of the data is measured and other elements such as component
values may be assumed ideal or unknown at the time of simulation. Some of
these factors include:
• Measurements of final results are generally
taken at a time much later than the original transducer measurements. Environmental
conditions (temp, boundaries, references, etc.) often change between those
periods of time and can affect the transducer response.
• Components may not be modeled accurately
enough to represent their real behavior. This is entirely under the control
of the user and the effort, time, and care they take to represent the components.
Often a problem for passive crossovers where component characteristics are
very complex. Modeling an inductor as a fixed resistance & inductance is
only a crude approximation.
• Measurements of drivers operating alone,
and then together as a system, will likely produce changes. Mutual coupling
is present when they are operated together in the crossover regions, which
was not the case when they were measured alone. |
