If you were given the choice of one of these tweeters, which one would you pick?

1. DRIVER TYPE: phenolic compression. MAGNET WEIGHT: 20 ounces. BODY DIAMETER: 4 3/4 inches. WATTS RMS.: 75. WATTS PEAK: 150. FREQUENCY RESPONSE: 1K to 15k Hz. SENSITIVITY (dB@1w/1m): 105. Now with 2 inch voice coil, 8 ohms. NOTE: Although a phenolic horn driver and a Piezo horn driver can reproduce about the same range, the phenolic driver does it much smoother with less harshness. That means its easier on your ears. This is a very popular driver. We've seen it in many catalogs with specs varying dramatically. Some list it as 80 watts with a high end of 12k to 20k. Size: 4.75 x 3.0 Weight 4.75 lb.

2. Threaded driver with titanium diaphragm and 1.5 voice coil. 50 watts RMS., 100 watts peak. Can be used in cabinets with a continuous power rating of up to 400 watts (Should NOT be used without a crossover). Frequency response- 1.5 kHz to 20 kHz. Sensitivity- 102 ±2dB (1w @ 1m). 8 ohms. 25 oz magnet. Size: 4.375 x 2.625 Weight 3.0 lb.

I wouldn't pick any until I saw a response curve of each in the horn I was planning to use showing both on axis a whatever was available for off-axis results. Once I had the curves in front of me I would need the response curves of the woofer or midrange that would be under it. Then I would need to know the intended purpose of the speaker unit. Is it being used as a ceiling PA speaker, a home audio speaker, stage monitor, keyboard monitor, FOH main, side fill, near field studio monitor, etc.

I prefer compression drivers myself. #3 looks to be the best choice.

For use with what other components? I'm with Fred, in general, on compression drivers.

Ok let me make this a bit simpler.If you were building a simple three way system using a three way electronic crossover Tweeter box, Midrange box and Woofer cabinet/enclosure.......... off the cuff which would be your first choice (Remember you can set the electronic crossover to whatever roll off frequency you may want.) BTW the horn would be a 4" by 10" simple horn. Lets concentrate on the driver,eh!
