Goldwood GT-302/S 1/2" Mylar Dome Tweeter Shielded
Goldwood GT-302/S 1/2" Mylar Dome Tweeter Shielded is rated 3.9143 out of 5 by 35.
Rated 2 out of 5 by from Quality control is poorI am a retired audio writer (four books; 150+ magazine articles) and build speaker systems as a retired-person sideline.I purchased four of these to use as tweeters in some surround-channel speakers I was building (two for immediate use; two as spares for later projects). Because surround speakers need not match the quality of the L, C, and R mains, it was not necessary that the tweeters be outstanding ones, and one does have to admit that the price of this tweeter is attractive.However, of the four, only one was decent when given preliminary testing as left and right main-channel speakers to make sure they were working well. With a 2.5 kHz second-order crossover the three "duds" emitted substantial crackling sounds between 2000 and 1500 Hz with frequency sweeps, and were unworkable with music. I partially fixed the problem by changing the crossover frequency to 3500 Hz, but the three "duds" still emitted fuzziness over much of their operating range above that frequency. The one good unit performed OK with both frequency test sweeps and music. However, the defects with the duds were easily audible with quality musical source materials.I have ordered SIX more of the units, because they are low in price and I need to fit a good tweeter into the custom cutout I made for the design in the panel. Hopefully, one of the six will be decent. I believe this would be a decent tweeter IF the QC was as good as the one out of four that performed OK. However, if the QC remains as bad as it has been so far I would not recommend this tweeter. We shall see how well the six I have ordered perform.

Rated 5 out of 5 by from Not BadNice base model OEM type driver. Not bad at all for the price. Magnets much heavier and stronger than I would expect for this type of driver. Overall, a surprisingly nice speaker.As others have said - be careful soldering to the lugs - very quick and hot does the trick.I am using these wired in parallel via 2.2uF mylar capacitors to some old 8" full range speakers. These tweeters add just the right amount of "sparkle and life" to the sound from these old speakers. They pick up where the full ranges peter out.Satisfactory performance for a low cost base model unit.5 stars for performance to price ratio.As usual - prompt on-time delivery.

Rated 1 out of 5 by from Did not last for one minuteFirst let me say that I have been happy with sll my other buys from Parts Express. That said, I would not order these tweeters again if they cost 50 cents.. I ordered them for the size for a project I was working on. They were just about the perfect size to fit the job. I installed them in the cabinet and then noticed I was getting no highs from the speakers. I removed both of them and hookded them direct to the speaker wire and got nothing. They were both dead and non functioning. . I also ordered another pair that were almost identicle to these just a different magnet structure and the same thing happens again. I was using a small 15 watt per channel receiver that I always use to bench test everything , so No way did I overpower these little tweeters. I also read a review on these and they said they had a problem with trying to solder to the connections, so I didnt try to solder, i just pushed on the wire hookups. Sad to write a bad review, but I have never had any other product do this .

Goldwood GT-302/S 1/2" Mylar Dome Tweeter Shielded

What size female disconnects will fit the terminal? Part number for these disconnects? Thanks.

Asked by: Tony729
This tweeter uses 0.110" terminals. Our part number for the disconnects would be 095-286.

Which terminal is positive?  They are identical as far as I can tell.

Asked by: caddylackn
One of the terminals should have a red strip drawn on it, this will be the positive terminal.

can this be rear mounted, if so, what kind (if any) of gasket is needed?
Asked by: speaker freack
If you mean rear of the front baffle board--I would just use a cut out of cardboard since this tweeter uses a high crossover and it's shielded, so the back wave is compressed [sort of]. You want to prevent rattling by the large woofer bass waves though. PE has great gaskets for this as well. I hope you didn't mean "mounted towards the rear"? Since this is shielded, you would get very little sound.

which way should the grill be oriented. vertical or horizontal..? in addition...should the posts be touching the magnet..can they be spread

Asked by: f16voodoo1
The two small veins that are holding the diffuser in place will have no affect on the sound so the orientation won't make any difference. The terminals should not be touching the magnet, they can be bend if necessary.

The suggested Cutout diameter is: 1-15/16", can a 2" hole saw be used instead? I cannot find this size hole saw for an acceptable price as it is not a standard size. Otherwise what other suggestion do you have besides using a jigsaw to hack it up or a router?
Asked by: bjpell
Yes you can use a 2" hole without issue.
