Tiziano Posted July 21, 2018 Share Posted July 21, 2018 Hello everyone, I wanted to know if it was possible to use the T2A autotransformer on the Heresy 2 klipsch to attenuate the squawker at 12db thanks a lot Inviato dal mio G8141 utilizzando Tapatalk Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted July 21, 2018 Share Posted July 21, 2018 Here you go. You will need to calc the capacitor. Quote Link to comment Share on other sites More sharing options...
Tiziano Posted July 21, 2018 Author Share Posted July 21, 2018 Could you help me on how to do it?Inviato dal mio G8141 utilizzando Tapatalk Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 21, 2018 Share Posted July 21, 2018 Which crossover does your H2s have? Type E2? Try this experiment first to see if you like it. Quote Link to comment Share on other sites More sharing options...
Tiziano Posted July 22, 2018 Author Share Posted July 22, 2018 This is the crossover that I use on heresy, when I took these speakers practically had the mobile destroyed and totally missed the crossover, looking for I arrived here and I saw that this model was given as crossover for Heresy 2 and built it, not having the original autotransformer a friend gave me two T2A to try, and was practically used with the output - 9 dB, but I've never been convinced it was the right thing, so I ask you if you can adapt this T2A on my heresy.Sorry for my bad English (Google) Inviato dal mio G8141 utilizzando Tapatalk Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 26, 2018 Share Posted July 26, 2018 Tiziano, First, which Heresies do you have? Are the horns mounted to the front of the motorboard (front panel) or to the rear side (Heresy I)? If Heresy 1, use the circuit diagram I posted above and build it according to the black lines. If that is too bright (too much treble), try changing it according to the red lines. A Heresy II crossover would not be good in a Heresy I. All of the drivers are different. I do not know what kind of capacitors are available in Italia, but Solen capacitors are made in France and are acceptable and inexpensive. If you have Heresy IIs, you will probably be happier just building a -10 dB L-pad to get the squawker to the right dB level. Finding that 3504 transformer will be tough, even in the US, unless you buy a set of Type E2 crossovers. If you can follow this page, it will do your calculations for you. http://ccs.exl.info/installation/crossovers-installation-tweaking/crossover-calculators/#first Begin Google TranslateInizia Google Translate Tiziano, Primo, quali eresie hai? Le trombe sono montate sulla parte anteriore del motore (pannello anteriore) o sul lato posteriore (Heresy I)? Se Heresy 1, usa lo schema del circuito che ho postato sopra e lo costruisco secondo le linee nere. Se è troppo luminoso (troppi alti), prova a cambiarlo in base alle linee rosse. Un crossover di Heresy II non sarebbe buono in un'eresia I. Tutti i piloti sono diversi.Non so quale tipo di condensatore sia disponibile in Italia, ma i condensatori Solen sono fabbricati in Francia e sono accettabili e poco costosi.Se hai Heresy IIs, probabilmente sarai più contento di costruire solo un L-pad da -10 dB per ottenere lo squawker al livello di dB corretto. Trovando che il trasformatore 3504 sarà duro, anche negli Stati Uniti, a meno che non acquisti un set di crossover di tipo E2.Se puoi seguire questa pagina, farà i tuoi calcoli per te.http://ccs.exl.info/installation/crossovers-installation-tweaking/crossover-calculators/#first Quote Link to comment Share on other sites More sharing options...
Tiziano Posted July 27, 2018 Author Share Posted July 27, 2018 Thanks for your kind explanation. I have version 2 of heresy. I will try as you advised me.Inviato dal mio G8141 utilizzando Tapatalk Quote Link to comment Share on other sites More sharing options...
Tiziano Posted July 27, 2018 Author Share Posted July 27, 2018 On the Driver impedance box, do I have to set the nominal impedance or do I have to measure it with a multimeter?Inviato dal mio G8141 utilizzando Tapatalk Quote Link to comment Share on other sites More sharing options...
JohnA Posted July 29, 2018 Share Posted July 29, 2018 I would measure the DC resistance and use that to estimate the actual impedance. Expect the squawker (midrange) to be 16 ohms and its DCR would be about 12 Ohms. If you use an L-pad, the crossover will see a 16 ohm squawker instead of the 120 or so ohms it sees now. You will need to change the 1.5 uF cap to about 12.5. Quote Link to comment Share on other sites More sharing options...
Tiziano Posted August 18, 2018 Author Share Posted August 18, 2018 I measured the DC resistance and it is 11.3 ohms, so what should I put as an impedance? what capacitor value should I use? Thank you so much if you can help me Quote Link to comment Share on other sites More sharing options...

Thank you so much if you can help me The easiest thing to do us put an adjustable L-pad in. No guessing values, it's cheaper plus if you don't like the ammount of attenuation you don't have to buy more resistors. The mids were too hot for my liking on my KP-2500s and these were the best solution. I played with the mid attenuation for several days until I got the sound I liked. It's hard to do that with fixed value resistors. Sound quality did not suffer. Quote Link to comment Share on other sites More sharing options...
