Rated 5 out of 5 by from PE 3 3/8” Bullet versus Pyramid TW28 Tweeter (PE Wins!)I refurbished a pair of speakers I built over 30 years ago. I tried the Pyramid TW28 because it looked the same as the super tweeter I bought at Radio Shack. The performance was not exactly what I was expecting so I tried the Bullet Tweeter. It sounds terrific! It fit in the same diameter hole plus the bolt holes were in the same location which was really convenient. The cymbals in music have come back to life. I really like this tweeter. It is loud - I am using it with a 50 watt L-Pad so I can adjust it to the level that integrates perfectly with the other drivers. It is 8 ohm, which is nice because it is difficult to find 4 ohm L-Pads. Definitely recommend this product!Fast delivery, great selection of products, good prices and the technical team is willing to take the time to thoroughly discuss matters and are truly helpful!

Rated 5 out of 5 by from Speakers Work GreatI rebuilt a pair of BSR speakers I've had for yrs. The only thing that's BSR is the cabinet, after a complete rebuild from Parts Express and the tweeters where the last peace of a 3-way system. These bullet tweeters have just enough crisp to them but not to much they sound great for my application. The price was right, time frame getting to me was good. These cabinet's house 15 inch woofers, 11 inch mid-range, and these bullet tweeters. All hooked to a Carver AV-405 power amp and they rock { loudly }. Thanks Parts Express for having the right price's for me to be able to rebuild this system.

3-3/8" Bullet Tweeter

would a resistor be necessary for these?

if i put these in a cabinet with a GRS 8in poly cone. would the tweeters overpower the woofer with out a resistor? how effecient are these. tweeters can get pretty loud even if the spec sheet says 8 ohms, should i bumb it up to 10 or maybe 12? just want to make all the necessary purchases at once!
Asked by: mklein77
If you mean the GRS 8PF-8 or the 8PR-8 then yes, you will have to use a resistor to reduce the level of this tweeter. In fact, you'll have to reduce it a lot because this is a very sensitive tweeter, and those woofers have only an average sensitivity. This tweeter has a sensitivity of 100dB/W/m, whereas the 8PF-8 has a sensitivity of only 87dB/W/m. Using a simple L-pad calculator online, I found that you'll need a 6.21 ohm resistor in series with the tweeter, and a 2.31 ohm resistor in parallel with it. Alternately, if you just use a single resistor in series with the tweeter then it'd have to be a 27.73 ohm resistor. If you use the L-pad then you can use a crossover designed for an 8 ohm speaker (because an L-pad keeps the effective resistance the same), but if you use the single resistor then you'll have to adjust the crossover so that it works with the new effective resistance of the tweeter, which would be 27.73 + 8 = 36 ohms.

crossing over lower than 4KHz?

I'm in the middle of upgrading my Polytone Taurus keyboard amp and got that Celesion 15" woofer - already an improvement. I got one of these bullets already and just hooking stuff up with alligator clips and some random capacitors, the combination has promise (unfortunately no room in the cab for a proper horn midrange..., just 2 tweeter cutouts and the woofer).I'm getting a very nice sound from this tweeter (at low test levels) with a 12uF cap which seems to be about 1600Hz. Now, that's probably too low... but I'd like to cross over about 2500Hz or 3000Hz.What I was thinking was to put two of these tweeters in parallel, so the power handling would be comparable to the woofer (the amp in there I think is 150W total) and cross it over at the lower frequency.According to some online calcs, if I do a 2500Hz L-W crossover I have:C(t) = 8uFL(t) = 0.5mHC(w) = 4uFL(w) = 1mHThoughts?I wish they had published a frequency response graph for these tweeters...
Asked by: bowerymarc
ok, so I heard conflicting things there in that answer.... one is that lower crossover causes damage because the tweeter can't handle the power at those frequencies, then I heard that I don't need such higher power... so the second part would say the first part is actually OK...If you note, my cabinet has 2 tweeter cutouts, that's why the two tweeters. So I figure it gives me some flexibility in the solution.That's why I'd love to see a frequency plot for these tweeters, and maybe get some idea of how to derate them when crossing over at 2.5K or 3K.I also figure that the L-W crossover already has the response down by -6dB at crossover, which puts it down -18dB an octave below, where the tweeter's resonant frequency is. That seems pretty reasonable, no?

I want to replace a piezo tweeter in a peavey PM112 powered monitor with one of these. No crossover currently in the PM112. Could anyone suggest the value of the cap I need to cross at maybe 3000 hz between - + poles on tweeter? Many thanks.. John

Asked by: guitar5
With only a cap you will want to cross over much higher, closer to about 8kHz. A 3.3 uF cap will work for this without issue.

Witch is more efficent, Louder in SPL? The catalog rated 270-055  at 100 DB and the 270-125 is rated 104 DB. I an looking to select the most efficent tweeter, whether the 270-055 or the 270-125. Please compare and submit the results. Thank you inadvance

Asked by: thundersnow2015
The higher the number, the more sensitive the speaker, no audible comparison required. The 270-125 is rated 4 dB higher so this would be the most sensitive of the two.

What is the dispersion of this horn?

Hi, I assume that it is conical but what is the dispersion degree? Probably 50 or 60 degrees? Thanks
Asked by: Sonicxtasy
This is a 60 degree horn.
