Solid and well made tweeters, A bit of a puzzle...there are three connectors on each tweeter, one on one side and two on the other. I ignored one of them and wired them up to my second speaker output on the amp. Works fine with a good sharp tweet. Better than the 10 watt Drok tweeters I bought only a few weeks ago. These are 20 watt and sound just about right for my system. Considering the price I paid for the Drok, this is really good value. I recommend this to anyone who wants to add tweeters. At this price, if you don't like the result, it's not a big gamble.

I bought three pairs of these - and none of them work! literally no movement whatsoever on any of the six units. All dead! I stupidly didn't test them before installing.

This is a good tweeter concerning the relation price/effect… Delivers very good sound... It does not have references about who manufacture it and the weight leads to believe that don't have strong built in materials, so don't expect that it will last for a long time… These kind of square dome tweeters are not easy to find on the market and if you want a good reliable one, with manufacture reference, you will pay around 90 € for it (I only found one, from Yamaha, that fits on my old speakers boxes - I search for the ones I had originally, which were “Westra” but I’m afraid that this manufacturer doesn’t exist anymore). Therefore, depending of the use you will give those tweeters you will see how much time they will last. My first one was frequently used and it last a little bit more than one year… For the price, I guess it is fair enough…
