1/2" Mylar Dome Shielded Tweeter 8 Ohm
1/2" Mylar Dome Shielded Tweeter 8 Ohm is rated 4.3333 out of 5 by 6.
Rated 5 out of 5 by from Great tweeters for the priceI bought 4 of these to use in my old truck, They are excellent tweeters for the price, and were a huge upgrade over my old coaxial set-up. I'm using electrolytic caps as 1st order crossovers set at 4225 Hz. Everything between 4200 and 900 Hz is covered by 2 5.25" drivers and 4 4" drivers. Everything between 850 and 80 Hz is covered by an 8" woofer. everything below 100 Hz is covered by a 12" subwoofer. I'm no audiophile and I don't compete, but this setup sounds better than anything I've heard. I also spent less on this setup than what I sold my coaxial speakers for, you just can't beat the prices on parts-express, especially if you find a buyout.

Rated 4 out of 5 by from Will reorder this product if it's still available.Can't beat the product for the price. Be a little careful if you are using a high power solder iron, as the plastic will melt if the iron is on the solder point's too long. A good economy tweeter.

Rated 5 out of 5 by from Sweet sounding tweeters!Don't let the low price offered on these tweeters fool you. I purchased a pair to replace blown Sony tweeters. They are sounding as good, if not better, than the originals.

Rated 5 out of 5 by from A very good deal!I used these as direct drop-ins for the blown tweets in some older Polk Mini Monitors. Perfect fit and sound quite good. I may try them w/out the resistors, as 3 o'clock on the treble knob is needed for "normal" sounding output.

Rated 3 out of 5 by from Nice priceFirst I have to say finding a tweeter like this for under 2 dollars is incredible, I threw 2 of them in my chart for grins,. However Its performance is about what you would expect for 2 bucks! Even in a economy speaker build I would step up to a 5-10 dollar fabric or metal tweeter.

Rated 4 out of 5 by from Can't beat the priceI replaced the 18 year old paper tweets in the dash of my Volvo with these. I crossed them over at 6000 hz and couldn't be happier with the sound and the ease of installation. (They fit right inder the factory grills and and are held in place with wire ties :))

I am trying to replace a tweeter that looks exactly like this but it is 6 ohm with something better. There is only 4" between the other two speakers. Any suggestions?

Asked by: BrettM63
We have many tweeters that are smaller than 4" that could possibly work. While I cannot give you a specific part number, I would recommend a dome style tweeter as a replacement since they are generally regarded as a nicer sounding tweeter than mylar. All dimensions are listed for cutout and faceplate diameters, so find something within your price range that will physically fit in the space you have available.
