In Reply to: Re: Again, have you ever measured drivers? posted by Brian Cheney on July 30, 2002 at 20:32:59:
My query concerning the T/S parameters of your drivers obviously an assertion concerning something else with in the speaker SYSTEM that is quantitatively measurable.Your avoidance of this issue is quite astounding. You are a most clever.
I have never hand trimmed or modified any drivers. It is quite obvious by your conveyance that you are more than eager to convey how accurate they are following your endeavors.
So, I'm ready. How close are the T/S parameters to 1/200%?
You eluded to it in your last post with, "What do woofer t/s parameters have to do with capacitor tolerance? They aren't part of the woofer crossover which is accomplished with a very high quality, 1% tolerance coil."
Are you saying that 1% is acceptable tolerance for a woofer inductor? Well, I have unwound them for value and totally agree. You still failed to mention anything about the T/S parameters.
I do understand and designed a few simple crossovers. This was accomplished by swapping a wall of components until I got everything satisfactorally correct. I understand what a respose curve is and how it moves/shifts when components are implemented. This is rather simple. It doesn't take an expert to understand this issue. It also doensn't take an expert to realize that trimming a capacitor to 1/200% isn't audible or measurable. At about 1% on my jig I can start to see a bit of movement, but this is "iffy".
Answering my question concerning the T/S tolerance of your drivers (especially after all of that fancy hand trimming) would be nice.
