Rated 5 out of 5 by from PerfectThe design fit great. I was able to use the same screw holes as the originals I was replacing! An for price versus quality there is no other speaker that matches it.

Rated 5 out of 5 by from good tweetyGood 'nough. What do ya want for a buck? I took two of these guys and mounted them alongside a Bi-amped co-axial to replace a blown tweet in a 30 watt peavey keyboard amp.. they haven't blown up yet, highs are crispy and not harsh - minimal distortion. Can't be beat for the price.

Rated 4 out of 5 by from Great deal - ideal replacement tweeterI bought 10 of these - I needed one to try out as a replacement tweeter in an old Minimus7 speaker - but for the price the additional 9 will be fun to experiment with.First - the replacement application. The Minimus7 uses an odd shaped custom tweeter. So I needed something with a small footprint to replace it with so this product seemed ideal. Another reviewer also mentioned it was possible to cut the plastic mount down in size a bit but I did not need to do this. This tweeter is a bit more directional than the original, and perhaps a bit less sensitive. It certainly worked perfectly - listening to a pair of these speakers, one with original tweeter and one with this replacement - they sound great. Much better than no treble on one side! Sure - if I rock the balance control back and forth I can hear a difference - but listening to music you do notice this. For just over a $1 problem solved!As a tweeter for a new project these would work - but you get what you pay for. Don't expect crystal clear hi's or response that extends down into the low mid-range. This is a 1/2" tweeter with a smallish magnet structure - by itself it sounds more like a super tweeter. I paired one of these with two of the closeout 6.5 mid-woofers PE has on sale right now in an MTM configuration and the sound was quite pleasant. I plan to build three of this configuration to use as fronts and center in a home theater setup. These are perfect for this application.PE's offering such great products at such low cost is awesome for those on a budget (like me) who want to experiment with speaker design. I love shopping the PE close out page for bargains like this. As long as your expectations are reasonable you cannot go wrong with a pair of these as replacements or for experimentation. Get some before they are all gone!!

Rated 4 out of 5 by from Almost impressedPicked up a pair to assist in the upper octaves of a portable MP3 player I was building. Ended up not using it. What to do with extra speakers? I know, a buddy needs a pair of very small bookshelf's. Coupled with a Fountek 3", also from the Parts Express clearance rack, put in a 3.75 liter enclosure tuned to 75hz, padded down the Tweeter with an additional 7 ohms of resistance to get the sensitivity right, worked out a very simple 6 db crossover at ~4000hz (the Fountek's run full range) and done in 4 hrs minus painting of the boxes. MUCH smoother then they have any right to be for less then $2. They even try their hand at making a sound-stage. There not Scan-Speaks, but for a dorm room bookshelf, they sound really good.

Rated 5 out of 5 by from Incredible quality for the priceI needed tiny tweeters to install in a small portable Bluetooth speaker cabinet. The available area in the cabinet to install tweeters is extremely limited. I took a chance that I would be able to cut the tweeters down, and it paid off. I used a band saw and cut off as much as the outer mounting flange as I could. I then used a small belt sander to make it even smaller. I wound up doing this to 3 speakers, and I'm totally happy with the results. I had upgraded a similar speaker using a pair of Tang Band 1/2" tweeters, but these at a fraction of the price of the TB tweeters, sound better. I elected to go without the resistor, as I needed a bit more high-end. I bought 10 of these tweeters and checked every one. Not a bad one in the lot.

1/2" Mylar Dome Shielded Tweeter 8 Ohm

I would like to use these tweeters in a budget garage speaker project along w/ the GRS 8" full range. What would a good starting point be for the crossover? I want to keep it simple (cap only), using a sealed cab design, powered by Lepai 2020A.

Asked by: safTguy
A 3 uF cap would be a good place to start for this tweeter. You can go lower in value for a higher crossover point, but I would not recommend larger than 3 uF.

Is the 88dB measured with the 2.2 Ohm  in series?

Asked by: MKEM
The Reason I asked this questions is because the tweeter was too load when paired with a HiVi B3N. However, tired of waiting for a reply, I just replaced the resistor with a 4 Ohm and like the balance much more. I used a simple first order crossover with 2.2uF (poly) and 0.1mH (air core). The B3Ns are tuned down to around 48Hz and these tweeters add a real crispy high end. Loving the sound as desktop speakers.

How well would these work with the Aura NS3-193-8A? Crossover around 8K?

Asked by: ScoWill
These should work well for that application.

I have a few pair of Dayton b652. Except for the color of the "cone", these look identical to the tweeter in them. Is it? If not, is this a higher or lower quality part? 

Asked by: Anonymous
The 292-438 GRS 1TM-4 is a closer match for the original specifications of the B652 tweeter. This tweeter is similar quality, but has a dual magnet assembly that may result in different performance from the original B652 tweeter.

does the included res. work as a "crossover"

Asked by: rbair
No it does not,  it only buffers the output- a simple first order crossover could just be a 2.2 ufcapacitor in series , a shallow slope starting at about 9000 hrtz. Wire the capacitor in line onthe tweeters + terminal.   ERSE has a free online crossover calculator.

Which terminals are used for 2.2Ω, 5 watt ?

Asked by: ROCKETT
You will want to use the two terminals that are side by side if you want to use the resistor.
