Dayton Audio ND20FA-6 3/4" Neodymium Dome Tweeter
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.

How well do these do off-axis?
For information of this type, you can get manufacturer graphs and data in the manuals and resources area on the same page just to the right of the product description. From use and testing, this driver has fairly good off axis response, generally above 6k the response drops off as you move away from dc. Most notably 10k - 20kHz. But in listening, I personally prefer slightly off axis as many tweeters of this type can be overly bright on axis. This driver is less fatiguing, and is more open and airy, than other "budget" tweeters.

What size disconnects should I use with these?
These are 1/8" wide spade lugs, so you need 1/8" 18ga minimum slip-on lugs, crimp or solder.As a rule, I solder all speaker connections and restrain wiring with tie-wraps to the speaker frames. This does not require lugs, but mainly for troubleshooting; knowing the speakers are soldered, a failure [no sound] is likley something else [on the outside]. This goes especially for HT ceiling and wall installations.
