1/2" Mylar Dome Shielded Tweeter 8 Ohm
1/2" Mylar Dome Shielded Tweeter 8 Ohm is rated 4.3333 out of 5 by 9.
Rated 5 out of 5 by from Sounded goodBought 2 of these and used 4.7 mf capacitors and 2 292-405 woofers for an old set of Jensen bookshelf speakers that were my Dad's. Although the cabinets were twice the size of the sealed box recommended size for the woofers they still sounded pretty good.

Rated 4 out of 5 by from Replaced tweeters in Bose 201 Series IIIThese Speakers definitely did the job at less than $2 each. Just note.... the small lead is the negative, I used the far positive across the magnet and not the close one bypassing the use of the resistor. Be careful and use minimal time in soldering the connections as they will QUICKLY melt at the speaker connection point. If this happens, you may have to reset the mount with your solder iron quickly heating it up and melting the plastic and having the speaker powered up to make sure a new position connection is made. It happened to both my speaker. I also had to re-drill three new holes. Other than that, the speakers sound perfect in my Bose and look great too. Great replacements that made my Bose come alive again!

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.

1/2" Mylar Dome Shielded Tweeter 8 Ohm

hi will this fit a Yamaha N 6490 bookshelf speaker?

Asked by: SMF63
Unfortunately we do not have a cross reference guide for speaker sizes. You will have to verify the dimensions with the cutout the enclosure has to see if it will fit. As long as the impedance matches the original is will work without any crossover mods.

Is this 8 ohm with the resistor in series?

Asked by: j_doggggggggggg
The DCR is 8.27 with the resistor in series, this can still be classified as an 8 ohm load.

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.
