1/2" Mylar Dome Shielded Tweeter 8 Ohm
1/2" Mylar Dome Shielded Tweeter 8 Ohm is rated 4.4118 out of 5 by 17.
Rated 5 out of 5 by from 1/2" Mylar Dome Shielded Tweeter 8 OhmI was able to repair the tweeter horns on two MTX speakers with these tweeters. The speakers sound great now.

Rated 4 out of 5 by from for a buck, ya cant go wrong!They work, sound decent enough for a non critical listening application. Bought 16 of them to use in a line array project on the cheap. Have yet to finish the build.

Rated 5 out of 5 by from Perfect drop-in replacement! 99 cents well spent!I bought 2 of these tweeters to use in a pair of Auvio 6.5" bookshelf speakers that had blown tweeters. These were a direct drop in replacement, no modification needed to the enclosure to get them to fit. Only modification I made was removing the 2ohm resistor and putting a 2.2uF 50V capacitor in its place, to act as a high pass filter at around 8kHz. Works like an treat; the new tweeters sound even better than the old ones!!!

Rated 5 out of 5 by from Very Supprised!Did not expect these little guys to sound nearly as good as they do for the price. They do not sound quite as good as top end equipment but pretty close. They brought my old speakers back to life.

Rated 4 out of 5 by from Can't beat for 99¢These little tweeters work great for bookshelf speakers match my tweeters to the tee and really don't sound bad at all. Can't ask for much more at that price uno! They did the trick for me.

1/2" Mylar Dome Shielded Tweeter 8 Ohm

I'm using a 2.2mf cap on the tweeter,the woofer has no crossover just it's natural roll off. Will putting a resistor between the amp and the cap on the tweeter affect the crossover point? (That is before the cap not after ) 

Asked by: jim80

I would like to use these tweeters in a budget garage speaker project along w/ the GRS 8" full range. What would a good starting point be for the crossover? I want to keep it simple (cap only), using a sealed cab design, powered by Lepai 2020A.

Asked by: safTguy
A 3 uF cap would be a good place to start for this tweeter. You can go lower in value for a higher crossover point, but I would not recommend larger than 3 uF.

Is the 88dB measured with the 2.2 Ohm  in series?

Asked by: MKEM
The Reason I asked this questions is because the tweeter was too load when paired with a HiVi B3N. However, tired of waiting for a reply, I just replaced the resistor with a 4 Ohm and like the balance much more. I used a simple first order crossover with 2.2uF (poly) and 0.1mH (air core). The B3Ns are tuned down to around 48Hz and these tweeters add a real crispy high end. Loving the sound as desktop speakers.

How well would these work with the Aura NS3-193-8A? Crossover around 8K?

Asked by: ScoWill
These should work well for that application.

I have a few pair of Dayton b652. Except for the color of the "cone", these look identical to the tweeter in them. Is it? If not, is this a higher or lower quality part? 

Asked by:
The 292-438 GRS 1TM-4 is a closer match for the original specifications of the B652 tweeter. This tweeter is similar quality, but has a dual magnet assembly that may result in different performance from the original B652 tweeter.

does the included res. work as a "crossover"

Asked by: rbair
No it does not,  it only buffers the output- a simple first order crossover could just be a 2.2 ufcapacitor in series , a shallow slope starting at about 9000 hrtz. Wire the capacitor in line onthe tweeters + terminal.   ERSE has a free online crossover calculator.
