Hi Steve,

Yes, flatten the curve first (ideally to about 1.5 octaves past the crossover frequency), then apply the LR4 Lowpass. After this, use ARTA's target curve to compare your results with. The two responses should closely overlap to about 1.5 octaves past the crossover frequency.

Please keep in mind my comment in post No.103 (last paragraph) that the accuracy of a nearfield response is limited at high frequencies. This limit is dependant on the drivers diameter! For your 15 inch driver, an accurate response can only be guarenteed to about 332Hz!

Peter
