Do whatever floats you boat. There's always more than one choice. In the case of my Indianapolis system, I finally found a Tweeter driver that had the same sensitivity as a K-1133 driver on a K-402 horn. I only had 1 capacitor in series with each driver. Only 2 capacitors and Zero Autoformers and L-pads. IOW, the simplest possible. Then I used a Behringer 2496 on the bass section with no PEQ, and only a bandpass from 50-300 Hz. The Danley DTS-10 subs were driven by a sub output on my AVR set to 50 Hz. Simple and VERY effective, not to mention sonically impressive for all who heard it.

Deang Posted April 6, 2020 Share Posted April 6, 2020 I think so. There were quite a few of them. Quote Link to comment Share on other sites More sharing options...

There are phase issues with Autoformers, but if you look at a Khorn, now or old, phase coherence is not one of it's primary benefits, especially to those whose hearing mechanisms are insensitive to that aspect of speaker performance.

It's actually a good idea if you want stepped attenuation without having to change a Capacitor values in a first order network. 1 Quote Link to comment Share on other sites More sharing options...

I have and ALK network that has one. I tried a passive top end with Tractrix horn and JBL Large Phenolic drivers on a Jubilee bin as a 3-way with DaveA's LMAHL tweeters. Sounded really good, similar to TADs on a K402 with Xilica Xover, but if was not for long or for critical measurement or comparison. I was just playing before I sold the Jubes and plugged my dormant SH-50's back in and added big TH subs........a much better use of space, which is at a premium for me. So I never listened critically or measured the effect of the swamping resistor on the Xover point, but it is a useful component in an Autoformer based network.
