Crossover Design References
Not all these papers and articles are referenced in the main text of this book. They are of varying value and significance. These references are to crossover design itself; references relating to peripheral matters like filter design are not included. Papers relating solely to digital crossovers have also not been included. The majority of these papers come from the JAES, the Journal of The Audio Engineering Society. These can be purchased on-line at www.aes.org/. The cost is currently $5 per paper for members and $20 per paper for non-members.
