🔊 Goldwood Sound GT-1005 - 8ohm Piezo Horn Speaker Tweeter, 75 Watts, Black Review

I bought these for use in a homemade rodent repeller, not for the high precision applications described in most other reviews. I was able to get a measured 100dB of sound at 20kHz one foot from a speaker with an input power of about 0.34 watts to the active speaker. (The beep lasts half a second and repeats every minute. The total average current draw is only about 3mA at 6-12V at the 5V input of the regulator, making it suitable for battery operation. The circuit uses a full bridge, to achieve

these tweeters are the best you can get. Many people are looking for the loudest, but not necessarily the best. If you look and listen to the tweeters and look for things like Proper equalization is key to getting the best sound, and as I said before, a lot of people don't do it. I would definitely recommend these tweeters to general consumers and sound lovers. Just make sure you don't turn them up loud for the first few hours once you have them, if you want the best sound out of each speaker…

I needed 12 of them. You will love them too. All you need is a good equalizer and they will do what you want them to. Bright, shimmering. however. Also no ohm load! After a few months of listening they may seem too bright. Installed a cap to remove some bass distortion. Good cheap pace. Right, but there are better tweeters. They shine brightly at a frequency of 6-8 kHz, these tones drown out higher frequencies. They can start irritating your ears. Just to update if you keep putting out great…

Over 20 years ago, I built the pair of speakers pictured in this review, replicating the design of a Long Island speaker manufacturer that made inexpensive professional audio speakers. The only difference between my build and professional speaker builds are the components I use like the woofer, tweeter and midrange. PLUS, the difference is in the wood used for the body, internal wiring and high quality crossover. Needless to say, my speakers performed MUCH better and stood the test of time. I…
