Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter
I want to build a boombox with 2 Dayton ND91-4 and 2 ND20fa all in a single .23 enclosure. Can you recommend assembled passive crossover? Will be using Dayton DTA-120 to power the build.
Was the new stock really delayed from late December 2014 to early March 2015? I was hoping to get a pair of these for some Overnight Sensations MTMs. Being an overseas customer I need everything to be available at the time of purchase.
The current ETA for this tweeter (as of 1/5/2015) is January 9th. That is a Friday so they may not show up in stock until the following week.

what kind of filters do you recommend for this tweeters?
I would recommend a second order filter at 5,000 Hz.

I have them in use with a Dayton DC160-8 and a RS52AN-8 2" Dome Midrange. I am x-over at what I believe 650/8000. Can I attenuate the tweeter with Ωs to tone it down. I had to add 8Ω to the mid and that helped. Or do I need different x-over points.tweeter:21.54uF/0.41mHmid: 21.54uF/4.22mH 0.41mh/1.75uF (bandpass)woofer: 4.21mH/15.76.IN a .57 cuft box tuned to 45hz. Bass is ok. The rest is just too much. Tweeters are mounted in a baffle-less "egg" setup
Usually, a resistor will lower the volume w/o changing the crossover point "IF" it is inserted between the crossover's input stage and the high pass filter. An 8 ohm resistor will decrease the volume of this 6 ohm tweet by about -3 or -4db. A 16 ohm would be around -6 or-7 db. Check PE's "building crossovers" or "building loudspeakers" for the exact numbers. You can always use a pre-made variable"L" pad for this as well.

Im trying to make a small speaker project and this is the only tweeter that will fit, so im going to put two 4 inch woofers PN 292-404 with a 1.5 MH coil PN 255-052 what capacitor should I use now heres the thing. I will be using this on the Sherwood RX-4109 receiver PN 252-230 and it will only accept a 8 ohm load or else it overheats and shuts off but these are 6 ohm so will it just get warm or still shut off
With a tweeter like that you will want to use a small cap, something like 2.5 or 3 uF. Crossing the tweeter this high will not hurt the receiver, there is very little current draw at those frequencies.

another crossover question
Hi , i was wondeirng if i can do a 3rd order high pass filter(18db) at 3500 hz on these tweeters ? or should i go higher like 5-6-7 k ?thanks
I would not recommend anything lower than 4,500 Hz with a third order filter.
