Goldwood GT-1005 Wide Dispersion Piezo Tweeter
Goldwood GT-1005 Wide Dispersion Piezo Tweeter is rated 4.4308 out of 5 by 65.
Rated 1 out of 5 by from tweeter? more like squawker!I bought these mainly out of nostalgia to use in My low budget speaker project. Visually they reminded me of the old radio shack super tweeters.However the sound was nothing like my memories of those old shimmering piezo-electric drivers with their endless headroom.The first thing I noticed was an audible hiss as soon as they were powered up and the sound that came out as soon as some volume was applied was downright shrill and squawky adjusting the treble control seemed to have little to no effect.Perhaps the issue was with My crossover .Not sure all I know is I swapped them out with some .99 cent mylar dome tweeters I had bought previously and the sound was 100 percent better. I think these tweeters only real usefullness could be in outdoor sound reinforcement where volume would be the main goal. I have been largely happy with everything I've purchased through parts express but sadly I cannot recommend these at all.

Rated 5 out of 5 by from Great Super TweeterI used an 8 ohms 20 watt resistor in parallel with the horn and an 8 ohms L-pad attenuator, a 2 mf capacitor got it to work above 10 kHz, they sound amazing.

Rated 5 out of 5 by from great buyI bought a set of these on clearance for 2 bucks each and was quite surprised with how good they sound.

Rated 5 out of 5 by from not bad for the pricegot 2 of these in each speaker box along with a 10" mid and are pretty decent.. got to be careful with the wire terminals though. and hand tighten the scews when u install these or will brake with the force of a drill.. had a set of pioneers that don't sound as loud as these..

Rated 4 out of 5 by from Veratile and unbeatable valueI bought 6 of these total for use separately in my various small homebuilt pro PA systems to supplement Pioneer 4 1/2" full-rangers that just need a bit more top to avoid needing EQ.For PA use they're very efficient and project very well in large rooms. They can be a bit spitty up close so I've bought a few caps and resistors to see if I can make them more pretty.I've also going to add these to my new 8-speaker 3" Tang Band line-array design, but I'm going to tame them a bit for that one.These are so cheap you'll feel free to experiment since blowing one on the way to perfection won't hurt at all.

Goldwood GT-1005 Wide Dispersion Piezo Tweeter

Is this a direct replacement for the Motorola? These would replace the piezos in Community CSX70 cabinets. Community glued the piezo horns to a larger horn. Are there 3 screws on the back?

Asked by: George Washington
Yes these will work fine as replacements for Motorola Piezos. There are three screws on the back of this driver.

I'm going to be putting 6 of these goldwood gt-1005 piezo tweeter in a box and nothing else how would i go about hooking these up? do i put a 20ohms 20watts resistor on each piezo on the postive side. Or how would you go about it.

Asked by: hook
I would wire them all in parallel and use a single resistor on the input.

I have 8 ohm speaker and I want to hook up GT-1005 Piezo tweeter part # 270-011 with it in parallel what capacitor should I use and do I need to add a resistor in series so I will have at least 4 ohms?

how ohms is this tweeter?

Asked by: davidmf
Being a piezo tweeter this does not have an impedance.

Add resistor?

I am trying to use these tweeters to emit a constant tone from a tone generator. I'm trying to get as much volume as I can.I'm using an Onkyo SR701 receiver to power them.I was told to put a 4 ohm or 10 ohm 10watt resister parallel across the posts of the speakers.The protection circuit in the Receiver kicks in with the volume at about 80%. I want to go louder.Also, the resistor gets very hot.I was told I'm wasting energy by using a resistor and I should just use different tweeters. I'm not experienced enough to know if that is true.Should I try different resistors? Or would I get better volume out of some 8 ohm tweeters? I'm trying to keep this as low cost as possible. What do you guys think?Use different tweeters? Which ones? Would like to keep total cost under $10 per speaker or tweeter+resistor.

3.3 uf non polar cap to feed 10 ohm non inductive and 2 0hm resistor... then 10 ohm to ground and the 2 0hm to + of the horn an additional 20 watt 20 ohm to soak up the residual power and load the amp... a siren type amp may better serve you along with a larger voice coil type horn,, i see burned parts in this project with out knowing all paramerers
