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 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.

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!

These are a OK cheap tweeters. There reason for 3* stars is simple:_I don't like when specifications are misrepresented to gain sale. First they are really 3.3 Ohm measured at terminals past the capacitors. Second the only ferrofluid enhancing you will find on them is when you DIY it on your own. I took both apart and the gap between dome coil and magnet is dry and no sign of rusty and dark ferrofluid ever. The reason why they sound so "good" to untrained ear is low impedience. With that said all above can be addressed on you own. Basically this is a nice and CHEAP raw material starter set...:) I am not sure about using them in a car since I am 100% sure that attachment point to the base will give up very quickly.Ok i have been using these for several months now. To fully match them with my 3 way floor standing speaker i have installed 6 db L-pad on each consisting of 1 each 4 Ohm , 10 watt ceramic resistor in parallel and 1 each 2 Ohm , 10 watt resistor in series. Moreover I installed a total of 12.7 uf each of non-polar capacitors (elna ) . As a result i got close to original crossover frequency of the 3-way speaker tweeter crossover. As a result these will not overdrive or step out of the line. Percussion platters , bells, vocals are really well defined - w/o any distortion, increase in soundstage. Again it only took 3 months of trial/error and about equal amount ($) per tweeter in parts to make them sound good. These were meant to be a lesson/ test for me to improve upon my current system, after which I wanted to get more expensive tweeters. In the end I decided to leave them in permanently . Be ware ! your results may vary depending on your ear and your system.I listen to vinyl+ Bi- amped AudioLab amplification + B&W 3 way speakers
