    Nice Horn For The Money

    Overall: 4 out of 5

    I purchased 2 of these and mounted them in prefab enclosures cut out for a square 8" woofer. I also added a L-Pad to allow me to match their level to the rest of the sound system. I first tried crossing them over at 2K but the mids were a bit too strong as compared to the high end and they sounded to "horny" - like a nasal sound and the higher frequencies were overpowered by the mids. I next tried crossing them over at 6K as a contrast. The nasal sound was gone but the horns lost most of their power and I had to turn the L-Pads up full. I next tried crossing them over at 4K and that seemed to be the best of the 3 crossover points I tried. I didn't have a filter cap to try crossing them over at 3K so I stuck with the 4K crossover point. The horns once again came to life and had plenty of volume at 4K. If you are going to use them in a 2 way system you may want to try crossing them at 3K and see how they sound. A great horn of the price.

    1.35'' Compression Horn Tweeter - 9'' x 9'' 200W RMS

    Overall: 4.5 out of 5

    To be honest, I wasn't expecting super duper high end audio from a 20 dollar tweeter. They were purchased purely out of curiosity , experimentation and a new toy with which to play. I'm not one of those so called audiophiles but more of a practical experimenter who often finds inexpensive components that perform as well as or better than some priced several times higher. I measured the impedance and frequency response using a computer driven circuit board that cost close to $3000, mfr. name withheld for obvious reasons. The impedance curves between 200hz and 20khz are close to indentical. The frequency response of one was about 6 dB lower that its twin above 10khz and dropped faster below about 500 hz. The unit was disassembled and inspected but no obvious differientiation could be made. There is no logical reason to speculate on the reason(s) at this point.. The response was done with a gated pulse to reduce/eliminate room reflections and much the same results were obtained with a continuous sweep vs gated sweep and at 1m and 2m. The responses were smoother running in gated mode which was expected. The input was a constant 0.7v and the SPL at 1m was about 79 dB. The impedance between 900 and 6500 is almost a straight line at 7 ohms. That equates to about 0.07w in that passband which is 23 dB below 1 w. Add to that the 79 dB measured and one comes up with 102dB, darned close to advertised spec. and I won't argue the accuracy of my measurements with such a close result.

    The diaphragm is metal, most likely aluminum or some alloy thereof (a test on this was not performed) and the speech coil is immersed in a magnetic fluid in the gap which accounts for the high power handling capacity. This was not mentioned in the specs but is considered a good advertising fact.

    These 2 units will undoubtedly be used to compliment a horn loaded 12 inch speaker being designed and tested for a friend's guitar. The response of the 12, a 55 year old unit with a massive alnico magnet and a very high mass corner frequency close to 900 hz. This compression horn will compliment that old 12 very well as the efficiencies of both in their passbands are equal within a few dB.

    Overall, the tweeter is quite satisfactory and considering the price, even better.

    Hoping nothing important was forgotten to include.
