My DIY speakers are sounding very nice. Hard to believe that these small speakers sound so good. If I haven't mentioned before I am also using 2 JL Audio F-113 subs.
Best Capacitors for Crossovers
I am now in the tweaking stage of trying different caps in my crossovers for my DIY homemade 2 way. I presently have and will soon try a 5.6uf 800 vdc +/- 2% Jantzen Audio Silver Z-cap.
I see that Mundorf, V Cap get a lot of accolades, and the Dueland are quite pricey.
Does anyone have a favorite?
I am trying to cross over at about 4500HZ at 6db.

Hi Ozzy, Yes, resistors in the tweeter section are usually to pad down the level. Tweeters tend to be very sensitive, around 98 dB for instance at 2.83V, while woofers, when all is said and done, may be around 87 dB for a small diameter woofer. So that's 11 dB difference. It's close to 10x the power needed in the woofer than the tweeter. I just posted sample files for my own DIY kit. It includes simulation files so you can play with the design and see how each part contributes to the sound. Best, Erik |
Ozzy, Here is a link to the LM-1 speaker kit. This particular page discusses the crossover, and how the tweeter level is set. http://speakermakersjourney.blogspot.com/2016/05/lm-1-bookshelf-crossover.html Best, Erik |
Eric, I can't open your sample files. The woofer I'm using is 90db and crossing over at 4500hz seems to be quite fine. Perhaps the tweeter is a little too much but with my "old" ears sounds pretty good to me. Even at this early stage of breakin my DIY 2-way sounds better than many of my other high priced speakers including B&W's. I tried to limit the amount of components in the crossover networks. As I stated earlier I made the crossover in a external box. They were made bi-wired, with separate wbt posts . For the woofer, I used military spec cryoed 12 gauge silver/copper wire. The inductor is also 12 gauge. With the tweeters I used 14 gauge pure .9999 silver wire internally and the Jantzan Silver 5.6uf Cap. I just ordered a DEQX Premate, with my JL Audio F-113 subs this ought to turn into something really special. |
