lARrybody Posted July 26, 2018 Report Share Posted July 26, 2018 Valkyrie's suggestion of removing the 2500uf capacitor is interesting. After doing some online research and reading many threads and opinions his arguments are starting to make perfect sense to me. If I was to install a on/off switch right after the 2500uf capacitor as depicted by the red line below, wouldn't this also disable the 10MH double inductor from the circuit. This way I could listen to material in both configurations and decide for myself if I perceived a difference. Link to comment Share on other sites More sharing options...
ligs Posted July 26, 2018 Report Share Posted July 26, 2018 Just want to point out Infinity QLS-2 used a similar LC(20 mh and 1100 uf) network to deal with Waltkin woofer(V.C.2) with only 2 ohms impedance for the purpose of extending low bass. http://www.infinity-classics.de/technik/manuals/Quantum_2_technical_sheet.pdf According to the article below, the large capacitor adds up to 6 db in the low bass area but also acts as a subsonic filter for 20 hz or below. Most powered subwoofers have built in subsonic filter. Therefore, I would view the original AR9 crossover was a very clever design. http://www.lautsprechershop.de/index_hifi_en.htm?http://www.lautsprechershop.de/hifi/aka_tief_c_en.htm Link to comment Share on other sites More sharing options...

If the goal is to eliminate the 2500uF cap, wire the switch across the leads of the cap. The switch will either short out the cap (i.e. bypassing it) or do nothing.
