Reviews

Tang Band W4-1798S 4" Neodymium Midrange Driver
Tang Band W4-1798S 4" Neodymium Midrange Driver is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Marvelously articulate...Used thes in an MTM with the 25-1743S tweeter, and they are one of my favorite sounding designs (Glucinium Amor). One of the cleanest sounds I've achieved, and quite adequate bass as well. Fix the energy storage at 1.5kHz with the right series notch filter, and these are shiny gems of sonic bliss.They are costly, but worth every penny!

Tang Band W4-1798S 4" Neodymium Midrange Driver

is 20k correct on the high end or a typo?

Asked by: richg1390
I would not recommend using this driver that high, and 10kHz is more logical with a supertweeter. It has awesome off-axis response, and actually quite nice bass in the right box. Very clear, articulate, and clean. There is some energy storage around 1.5khz, but the blemish disappears off-axis.Would I use it full-range? Not without some BSC and a notch on that issue.
