The “Micro Statements “ by Jim Holtz and Curt Campbell
In contrast to the Finalists Monitors, the MicroStatement crossover is rather complex. Due to the frequency limitations of the ribbon, I needed to push the
NE149 out to at least 3.5 kHz. While this was straightforward, it took the addition of a couple of notch filters to the 2nd order electrical
LP filter to provide the proper transfer function, phase, and impedance properties.
The tweeter is a more traditional 3rd order electrical filter with a couple of attenuation resistors thrown in for good measure. The crossover is at 3.5K although due to the steeper cross of the tweeter it appears to be 3.2K. Regardless of what we define the crossover point to be, the performance of the ribbon was not affected.
How Do They Sound?
Curt says, “I built and designed these after designing and voicing the Finalist Monitors. I expected some differences due to the tweeter change but was not prepared for the differences I heard after voicing these in. If you look at the response plots and off-axis plots, there is not a lot of measurable difference. Nor is
there much difference in the HD plots between the two. I’m not measuring whatever it is that makes them sound differently. ‘
‘Don’t get me wrong. The Finalist Monitors sound great. There is something about the MicroStatements that I find very appealing. The icing on the cake, so to
speak. To me, they have a more relaxing, coherent sound. I suspect it is the higher crossover point, but for all I know, I got the correct mix of
dark energy to dark matter in these. Since I’ve yet to see a quantitative measurement for either, I’ll leave it up to you all to decide which is better and why.”
