Goldwood GT-25 4" Cone Tweeter is rated 4.0417 out of 5 by 48.
Rated 5 out of 5 by from Good basic, affordable tweeterI bought this two weeks ago, and I'm glad I did....I combined it with the GRS 8PR-8 woofer and PE 260-174 crossover, to build a good sounding pair of two way tower speakers.Note: the overall diameter of these tweeters is 4", not 1.06". And the cutout diameter listed is too small. I used a 3 1/8" hole saw, and they fit perfectly.

Rated 5 out of 5 by from Great For ReplacementsUsed this in my MCS 3-ways in the "midrange" with a 4.7uF JB cap and it sounds better than the original. Solidly built and does have a warm aura to it. However, I didn't realize the tiny black circle on it was sticky, so I got some sawdust on it that I couldn't really get completely off - if you're a newbie like me remember this.

Rated 5 out of 5 by from Powerful tweeterI purchased this as a replacement for my 27 year old tower speaker. It sounds great!

Rated 5 out of 5 by from Great cone tweeter for vintage speakers.The specs for this tweeter were shockingly good for the price. I was concerned about the build quality but it exceeded my expectations. I only had to slightly bend the tabs and I had a perfect fit in my Harman Kardon HK-20's. The sound is more extended and yet balanced and dare I say smooth! Thanks Parts Express for selling quality products at a discount price.

Rated 4 out of 5 by from Great value tweeter!For under $5 this one is hard to beat. Good crisp clean highs from this little driver. Good size magnet, well built and produces surprisingly good results, making it the best under $5 tweeter I have seen!

Rated 4 out of 5 by from good value replacement tweeter for older speakersUsed this to replace the blown tweeters in a pair of JVC SP-7WD speakers. These were cheap, big-box speakers meant to impresses the novice audio buyer with their looks. The original hole was 2.9", which should have fit but the tweeter has a small ring on the back which necessitated putting a chamfer on the mounting hole with a dremel tool. Not a big deal.The tweeters blend well with the rest of the 80's paper cone components. I like how they sound and you can't beat the price.While I had the drivers out I also replaced the electrolytics with Dayton film caps. They definitely improved the sound quality.

Goldwood GT-25 4" Cone Tweeter

With the only spec being Fs, is there any way to get the component values to get the resonance/impedance peak out?

I have a 3-way MCS speaker system that had a speaker in it that stopped working that looked exactly like this one. I always thought it was a midrange but the crossover for it was a lone 4.7uF capacitor so is this the replacement?

Asked by: ivandezande
This will work well as a replacement for that speaker with a cap value of 4.7 uF.

I should have mentioned there is no crossover in the speakers I'm putting these in. Do you still recommend part # 027-422 for the capacitors?

Asked by: Mineshaft
That will work perfectly fine.

The capacitor on the tweeters I'm replacing is in-line, 16UF. If I got these, do I still need capacitors?

Asked by: Mineshaft
Yes you will still need capacitors for these tweeters, although 16 uF is a bit too low for a safe crossover with these. I would recommend a 4.7 uF cap for these Goldwood tweeters.

I'm replacing four 3" tweeters in a vintage solid state stereo console.  It's a GE C521 from 1966.  It currently has two tweeters channel mounted inside each woofer.  I believe the existing tweeters are 16 ohm.  Will this work?

Asked by: stevenU
If the original tweeters are 16 ohm these will not work unfortunately. We do not have any 16 ohm tweeters to offer, however you could use two 4 ohm tweeters and wire them in series to get the same overall impedance.

What crossover do you recommend?

I have a vintage hifi system, I'm replacing the two existing woofers with Goldwood GW-210/8 woofers and the tweeter with the Goldwood GT25 4" cone tweeter. Is there a prebuilt crossover that would work well in this configuration?
Asked by: MsJefferson
Since you will be using two 8 ohm woofers, I would recommend the Dayton 260-148.
