The different projects

3/9/13

The T27 has a peak at 10 kHz as well as dropof above that when crossed over by a 18 dB filter, KEF then made a more advanced one.





So this is what it looks when I connect crossover built as this. I use a 2.5 mH coil and low resistance in series with the bass driver.  All caps are plastic not electrolytics.

This is the result for the tweeter section, how it will work I have to measure.
This is the woofer and woofer plus crossover, there is a minor rise in system Q from 0.95 to 1.05

The work will be to match the woofer and tweeter, I am pretty confident that the woofer section will work, but not so sure that the tweeter section will tame the T27. Time will tell.

  1. How about a Zobel network across the T27??
