## Description

Product Description Square dome tweeter, 2.25", 20W rms, 8 Ohm Box Contains Square dome tweeter, 2.25", 20W rms, 8 Ohm

Review: Tweeting like a bird - 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.
Review: does not work, completely unresponsive. - 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.

## Questions & Answers

**Q: What is the distance between fixing holes?**
A: Hi the distance between the top left and bottom right holes to the center of each hole is 58mm

**Q: How do you wire these up? why is there 3 connectors? Am a wee bit confused..**
A: 3 connectors? dont remember having 3. anyway theyre not that fussy about plus and minus. you should have a speaker with a tweater and main driver speaker output coming from a crossover inside. if not connect a black wire to the minus wire coming in and a bipolor capacitor rated about 50 farads. if your speaker hasent got a crossover inside you can find them on amazon but they not cheap. i hope this helps.  fainling that have a look on wikipedia for speaker crossovers 2-way or 3-way depending how many speakers youve got in your enclosure.  they will sound a bit horrible if you wired them up to the speaker wired directly but they can handle a fair wattage.

**Q: What are thw dimensions? 2x2x2 cm quoted but can't be correct?**
A: 2.25 inch  - it says in the heading. But I was not impressed with the sound quality so never used / got rid of so unable to measure and tell you.

**Q: Is there just one in the box?**
A: Yes. One in a box. Order 2 for a pair.
