Hi Fellas,
Thanks for all the thoughts. One goal of this project is to get some nice speakers. But another is to learn more about how speakers are designed. So discussions like this are great for me. Although I won’t touch the active versus passive debate for now.
Thanks for taking the time to provide such a detailed response. Everything you say makes perfect sense and is good for me to learn about. Let me ask you a seemingly simple question. Admitedly coming from a palce of ignorance. If everything is fine except my plots are running consistently high (in this case) or low, why not just subtract (in this case) or add a few ohms to all data points?
Like you say, it’s precise and inaccurate. But, as I understand it, the inaccuracy is consistent and could be corrected with a consistent correction. Then you’ve brought the plot to exactly what you are shooting for. If the error is systematic and consistent, this idea sounds OK to me. But if the variance in the baseline changed with frequency, this idea would be bad.
As far as I can tell, when comparing my plots to those of Seas and Scanspeak, all looks as expected except for the shift up in the baseline. I’ve got data reflecting these drivers in these cabinets. It seems like a simple way to proceed to me. But I suspect that you will tell me that there is a reason why it’s a bad idea. Thanks again.
