Pyramid 300 Watt Marine Tweeter Speaker - 3.75” Aluminum Bullet Horn w/ 1” Titanium Dome Tweeter, 2k-25kHz Frequency Response, 4 Ohm Impedance, Heavy Duty 20 Oz. Magnet Structure -TW28 (Pair)

So, I gave these a brief test today, on my main system. My main system isn't vintage, but it's rocking a pair of Cerwin Vega VS-150s, which are actually the perfect speaker for this test. My amp in this setup is a Yaqin MC-100B tube amplifier, running Tung Sol KT-120 power tubes for a punchier bottom end. No tone controls. Source is a Phase Linear PL8000 linear tracking turntable (same as Pioneer L1000, but in silver), connected to a Yaqin MS-12B tube phono stage (mullard repro tubes). Hooked to that are my VS-150 Vegas, and I paralleled the new tweeters with the Vegas. These tweeters are a VERY good match for these big Vegas. The tweeters are very efficient, which means they're very loud. They're almost a perfect match for the Vegas as-is, however. I might try a resistor or an L-pad to turn them down just a tad. Maybe 2db at most, but if you have less efficient speakers (Vegas are 102db) you'll definitely want an L-pad to adjust them down. Now the sound... Vegas are not known for their clarity. The VS series had the best tweeters, but they're still not detailed. These tweeters fix that completely. Cymbals sound amazing, and the music was bouncing all over my room. I tested with one of my favorite recordings (the new Daft Punk album), and my ears were perking up with all the new stuff I was hearing -- or old stuff heard in a new way. The sound stage expanded enormously (again not a strong point of the Vegas). The big difference is after i listened to one whole side of the album, I listened to it again, but this time without the tweeters. It sounded flat and lifeless in comparison, like I was missing half the music. THAT sold me on these tweeters. After one listen, I can't stand not having them paralleled to my Vegas. Even if they do need a bit of tweaking, it's really not much, and they're very livable as-is. Only downside is I can hear a LOT more surface noise. Grumble. Time to buy a record cleaner.

I have a pair of Elac Debut 6.2 Bookshelf speakers and they sound good but was lack the highs. So I went on line to Amazon and I found the Super Tweeters I was looking for , and let me say they are heavy with their 20 Oz. magnet ( no cheap plastic tweeter ) these are heavy , they look great sitting on the top of my speakers the power and sound is awesome especially with my Sub woofer. I now have to keep my treble on my Yamaha Amp only half way and make few adjustments with my Teac EQA -30 Equalizer. The price was fantastic too. And I have a pair of Polk Monitor 40 Series II they work well with them too. You want more highs with your speakers and don't want to spend a ton of money buy these. Steve

I wrote "surprisingly", because Pyramid is usually not good quality stuff. I've bought a few of their items over the years, and was always disappointed. BUT, these are an exception. I bought these to augment a pair of floorstanding speakers that I otherwise really like, but the tweeters are a bit rolled off for my tastes, and I wanted to add some "air" to them. These did the trick. Now, I will caution you on how to connect them. It appears a lot of people are just paralleling them with their speakers, but doing so can drop the total impedance to a level that could overheat and even damage your amp. What I did was to split the feed to my amp with RCA tees, and added a Fosi 200 wpc amp just to feed the tweeters. This gives the added bonus of having independent volume control for the tweeters, so you can set them to be just right. The pairing sounds great! One further mention...this tweeter comes with capacitors in-line to block the low frequencies, which is necessary on any tweeter. But the caps these come with allow them to reach down into the upper midrange, so there will be some doubling. That wasn't a problem in my application, but I think it might be in some, depending on the speaker. If it is, just use a different cap that crosses the tweeter at a higher frequency, and that should do the trick. Lastly, give them some play time to smooth out before judging. But really, almost all speakers need some break in. As always, good listening!

The Pyramid TW28 tweeters with swivel housing have a fairly narrow range of application. I added a pair to my existing home theater system as a cost-effective way to improve the high end response. If you are looking to do the same, read on. Amazon markets these as 'super tweeters'; however the frequency response (2K - 25Khz) is closer to a standard high end tweeter. Similar enclosed top mount horn super tweeters, such as the (long discontinued but legendary) Realistic 40-1310 and available Fostex T925A both have a 5K-40Kkz response and are much more expensive. The Radio Shack tweeters sell used for around $180 on Ebay (I remember buying a new pair for $40 in the 1980s) and the Fostex tweeters cost just under $400. The human ear can't hear these higher frequencies, but the more expensive super tweeters have a flatter, more even, frequency response throughout the audible spectrum. What's important is how they sound. This is, of course, subjective, but to me they definitely sound bright with just a bit of a harsh edge (thus the 4-star rating). I attribute this to the lower crossover frequency (2Khz) compared to the more expensive units. This could be smoothed out with an equalizer. In all, they make a good addition to my system. Be sure to pair these tweeters with big enough speakers to balance the sound. Mine sit atop 6.5" 3-way Pioneer speakers (see photo). By itself, this would never work, but my home theater system includes a pinnacle center speaker and 12" KLH subwoofer.

I don't care to wear my hearing aids often. The sound quality I experience without them leaves more to wish for though. I had the idea for a long time to add a pair of tweeters to my sound system- which is simpy a mini amp powering an old pair of Onkyo speakers. I use the sound for a projector. There's lots of good word here in the reviews on the pyramid super tweeters. I thought I'd see for myself - especially since they are budget friendly. Well, I opened the box a couple of hours ago and have them placed on the outsides of my Onkyos. The difference is extreme. I suddenly hear the high frequencies, voices, and all other instrument sounds. And the stereo separation - its like I forgot what it was all about. The sound quality now leaves nothing left to desire. Thank you Pyramid.

These tweeters are very bright out the box and require some burn-in time to level out or maybe just get use to the additional high and loud frequency output. These are awesome at ~$20 and worth a try. They are heavy and have a solid build. I do not like the spring clip connections in the back - I had trouble getting 16GA wire in there without it fraying a few strands in the process. The logo comes off easily as I found out and looks better without it. I also do not like the swivel base as it is a weak point and not required if you do not permanently stick/glue your tweeters in place. I almost packed these up to send them back when I first put them in service. The sound was shrill and irritating. My current speakers have 1 inch domes and (I felt) sound well balanced as it was before these. I got these because I had and loved those Radio Shack tweeters that these are styled after from back in the days when they made decent speakers (and still have those RS tweeters in their box packed somewhere in the attic). These added a top end that I just was not sure about at first. I left them playing and it appears that they needed to break-in some and definitely they are much smoother now and more detailed sounding in the ultra top end. If I took them off now, I will feel that something is missing, so you definitely get use to them and learn to appreciate what they do. At the going price, they are worth it and maybe worth much more for titanium bullet tweeters. Enjoy!

I had 2 Sterling MX8 8 inch studio monitor. One of the monitor's amp burned. So I decided to convert these 2 powered studio monitor into passive monitor/bookshelf speaker. So I removed all the internal power supply and amp components. Bought Fosi Audio BT20A Pro external Amplifier. After some modification both are become ready to play. But the tweeter of those speakers refused to accept such a high power from the fosi audio external amp. as A a result built in tweeter gone, I mean burned. Finally I bought these Pyramid 300 external tweeter. Got very fast delivery, connected and started playing. Then??? Then just wow!!!! now I am getting lot more flexibility, lot better listening.

The first thing to understand about these tweeters is that they are inexpensive; for twenty bucks you get a big, bright sound that may or may not appeal to the individual listener. I have a pair of KEF C85 speakers that are in remarkable shape, except for the Uni-Q tweeters. The tweeters were filled with ferro-fluid, which dried out over the years and left the tweeters essentially dead. Since these tweeters are no longer manufactured (and positioned in the middle of the midrange driver), I wanted to see what I could get mounting a set of tweeters on top of the speaker cabinets. The TW28 fit the bill perfectly and at little cost. The TW28s did indeed bring the KEFs back to life. The highs returned, opening up the soundstage and making the speakers listenable. Unfortunately, the overall sound, to my ear, was harsh, brittle, piercing at times, and, ultimately, tiresome. None of this surprised me. Like I said, the TW28s are cheap, not bad, just cheap. They pointed me in the right direction. I purchased a set of Fountek NEOCD 1.0 Ribbon tweeters (as I write this, on sale here at Amazon for $45 each). These are modest but well-made ribbons that produce clean high frequencies. The KEFs sound good again, though that sound is undoubtedly different from the original factory configuration. I think the TW28s have a genuine appeal, depending on a given set of considerations, and are certainly worth $21. I'm not sorry I bought them.
