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?

Rated 5 out of 5 by from Big sound from a small packageI bought this Tweeter to replace the the tweeters in a pair of vintage Bose bookshelf speakers. I also replaced the woofers with Dayton Audio product. I removed theunbelievably cheap and simplistic crossover parts and replaced them with quality crossovers and the result was amazing. These tweeters are crystal clear with no coloration over a very wide frequency range.

Rated 4 out of 5 by from Great tweeterSee my review ofS650-8 61/2 inch woofer. I used this tweeter with that wooferfor a new system. Tweeter was better than a Klipsh bookshelfsystem.

Rated 5 out of 5 by from NiceI put these in a pair of bookshelf speakers along with Dayton 6 in reference woofers. The guy below me was exactly right, they are extremely clear without having any sharpness or shrillness. I have never heard tweeters that sound this good. They look really good too, the lip around the dome isn't bad at all like it is in the picture. I plan on building a whole set of speakers with these in them.

Rated 5 out of 5 by from Reference QualityThis little baby really has a reference quality sound,at low and at very high volume.These really are sleepers,they don't have that sizzle that impress at first, just a smooth natural sound with no shrillness, that gets better with time i have 2 pairs, had them for years.I give them 5 stars for being a budget reference tweeter

Tang Band 28-847SD Shielded Neodymium Dome Tweeter

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
I think the wrong spec sheet is posted by PE as well as the wrong name. I couldn't find any evidence of the 28-847sd on tang band's website. On the other hand the 28-1177sb seems to be what is pictured by parts express and what I received when I ordered the "28-847sd". I don't have measuring equipment to measure the specs to be sure but but it appears to be what is pictured in the tang band datasheet for the 1177sb.

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.
