Tang Band 28-847SD Shielded Neodymium Dome Tweeter
Tang Band 28-847SD Shielded Neodymium Dome Tweeter is rated 4.25 out of 5 by 20.
Rated 5 out of 5 by from Nailed it!!I wanted a natural and realistic sounding low distortion tweeter to use in my pictured 3 way paper woofers speaker design and that is what I got. I like it so much that at $27, it might be hard to try a different one on my next project.

Rated 2 out of 5 by from Good design/ Cheaply made.I used this in a 2way .23 box matches with the Dayton RS180P 8. The sound is OK in the lower Frequencies but at the very top it is a little harsh and tiring to listen to. Voices are good and are reproduced nice, music is decent but not great. All in all it ok for the price but NOT great by any means!

Rated 4 out of 5 by from GOOD SOUNDI BOUGHT THESE TWEETERS TO REPLACE THE 70740 TITANIUM JBL TWEETER, THEY MATCH WELL WITH THE SPEAKERS YOU MAY THINK THEY SOUND LIKE THE ORIGINAL, MY REVIEW IS LOW TO MED VOLUME THEY STAY CLEAR AND A TOUCH OF CRISP, LOW VOLUME WILL COME LATER

Rated 4 out of 5 by from Great sound.I auditioned this great sounding tweeter in a 2-way rebuild and found it to be clear and crisp throughout it's range. Due to it's size I was unable to use it but I know it's a great sounding tweeter and I'll keep it in mind for a future build.

Rated 5 out of 5 by from Excellent BrillianceI did not want to change the size of the OEM.Very satisfied with results for the size and price.

Rated 5 out of 5 by from Having a blastI put a pair of these into a pair of bookshelf BIC Venturi speakers that about 20 years ago (rated number one by Consumer Reports!). I can't believe I've been lugging these things around for 20+ years, but when one of the tweeters stopped working I replaced them with these. As I began reading the forums here, I thought, hey, why not build a crossover? I decided on a 4th order linkwitz-riley, even though I knew the X-over would take up a 1/4 of the cabinet. I used peg board and put the tweeter on one square, and the woofer on the other, being careful to align the coils perpendicular. Each was mounted on opposite sides of the speaker. I used solid strand copper wiring, and 3-waypush connectors (no soldering). I am not an engineer, and interpreting the first one (woofer) for wiring was tough, but the second much easier. I've only done one speaker, and have no software for calculating Zobel networks or L-pads(?!). However, just the 'cap and coil' difference in sound between the rebuilt speaker to the factory speaker was incredible. I put on Santana's ' Moonflower,' and was floored by the detail I was getting from this rebuild. About 30 minutes in, however, right when Carlos was starting to rip a solo in 'Black Magic Woman,' my Denon kicked off on what I assume was an overheat protection. That suprised me as I used an online calculator for the crossover set to 8 ohms at 2000hz.Back to the review of the tweeters. These sound fantastic, and my crossover really brought this little speaker to life. If anyone who reads this knows why my amp kicked off based on my rebuild (at 8 0hms), I'd love some feedback. Is it just a question of more robust amplification?

Is this a good replacement tweeter for Technics SB-TA310 (technics part # EAST25KH10A6)?

Asked by: Adrie
Unfortunately we do not have a cross reference available for this type of thing. As long as the impedance matches and physical dimensions are similar or the cabinet can be modified it should work fine.

What is the difference between the -847SD (displayed) and the -847SE (product page displayed)?

Asked by: Perkins
These tweeters are identicle with the exception of the trip rim color. The SE model had a silver trim ring and has been discontinued. The SD is all black and is still available. They are interchangeable.

The specs for the Tang Band 28-847SD (parts express item #264-822) are different from those of the manufacturer.

Is this an error in your published specs or is the 28-847SD different from the 28-847SE which displays when the Manufacturer Specification link is clicked upon? See Fs & Power handling.
Asked by: lignm
Thanks for pointing that out! We have updated the spec sheet.
