Tang Band 25-1166SJ 1" Neodymium Tweeter

This compact neodymium tweeter offers very refined performance that is unusual for this size and price range. An enhanced dome damping technique gives excellent high frequency extension as well as good low-end response. With ferrofluid in the gap and a damped rear chamber, crossover design becomes much simpler. The small mounting flange is excellent for compact multimedia and home theater systems.

Tang Band 25-1166SJ 1" Neodymium Tweeter
Tang Band 25-1166SJ 1" Neodymium Tweeter is rated 4.4286 out of 5 by 7.
Rated 4 out of 5 by from very nice, well priced.I purchased these a few months ago but just now got to install them. I mounted these in the kick panel areas of my car. Power is being supplied by a very old Rockford 22.5watt per channel amp. Crossover duties come from an Alpine head unit in 3 way mode. I have them crossed over at 3.2k with an 18db slope. I have only been able to play/listen to them for a few hours now (I have a 45min commute) so they aren't broken in yet, but I can say that compared to the "out of the box" component tweeters I was using these are worlds smoother, the detail is much improved and they are not fatiguing. Using time alignment to cheat for mediocre placement has me convinced that for the money these are great!

Rated 4 out of 5 by from Replaced M-Audio MonitorKids destroyed the tweeters. I installed a pair of these. The size diameter is not a match but they are close and they sound great. Great Value.

Rated 5 out of 5 by from very natural and smoothI used these in a customer's car and am very impressed with this inexpensive tweeter. I used mdt39's in my vehicle and wanted a similar sound for my customer, inexpensively. The small size let me put them where they needed to go, instead of where they would fit. Excellent soundstage. Never sound harsh or pushed. Effortless. I will use these again.

Rated 5 out of 5 by from Great valueI am using these with Dayton 2" midranges which I also recently purchased, in a 4-way car system. These are actively crossed at 5k up. Not completely broken in yet, but they are producing an effortless sound - I can't detect harshness like I had with my previous CDT Audio tweeters. I marked performance at 4.5 instead of 5 since it seems the frequency response trails off in the upper end. It could be due to placement/position of the tweeters, I need to investigate it.

Rated 5 out of 5 by from Excellent tweeter for the money!I bought a pair of these about two years ago for my car's high end. I run a 3-way active crossover pioneer setup, with pioneer mids, infinity perfect 10" low, and these for the highs. Most people can't believe what type of sound i get from 5 speakers. My favorite part about these speakers is their frequency range. The soundstage that they present is truly amazing. For $20 each they are a great buy.

Rated 4 out of 5 by from High Quality looks, OK soundI tried to like this tweeter. As with other TB products, I was impressed with its apparent build quality. Its versatile size and good looks are a plus. I tested several speaker arrangements and dozens of crossover variations for over a year, finally concluding it was not good enough for main speaker duty. I settled on a 6" MT used as rear surrounds. While it does have a well damped sound that is never harsh, it lacks the impact, resolution and effortless highs of some larger drivers. For best sound, avoid first-order crossovers. Try 12db at 3000hz as a starting point, since these do not work well down low.

Tang Band 25-1166SJ 1" Neodymium Tweeter

Since you guys were so helpful on another product, let's go for another. I have a set of Dayton RS75-4 and they sound awesome. What cap would you recommend for them. I love natural sounding mids that have a little low end, but not too much.

Asked by: Lawnboy
are you looking for advice on crossing the RS75, or the the tang band tweeter with the rs 75?
Answered by: Chrisf

Is a capacitor recommended for this tweeter? If, so, which one would be best?

Asked by: Lawnboy
This would require a capacitor with a value of 8.2 uF or lower. The Dayton cap in the link below would work for you.

Is the wider terminal the positive terminal??

I am trying to match the phases of my speakers. I need to know which terminal is the positive terminal.
Asked by: Sinayu
Yes, the wider terminal indicates positive polarity. Keep in mind that some crossover designs will do better when the tweeter is wired out of phase. I suggest listening to the speakers with the tweeter in and out of phase, and the way that sounds best to your ear is going to be the right way to wire them.
