Product Details

HiVi RT1C-A Planar Isodynamic Tweeter

The vibrating element of a planer tweeter is almost weightless in comparison to a dome tweeter. The element consists of Kapton film with a pattern of aluminum conductors which is placed precisely between two Neodymium bar magnets. It provides an immediate and precise response to any transients in the original signal. These drivers are magnetically shielded and feature a linear phase response which provides time coherent reproduction resulting in accurate musical rhythm and imaging. Unlike other conventional tweeters and electrostatic speakers, the RT1C and RT2a have an extremely wide sound dispersion in the horizontal plane. At the same time, they have a well controlled sound dispersion in the vertical plane. This helps to avoid disturbing floor and ceiling reflections in a home environment thus enhancing clarity and imaging accuracy. The RT1C features a radiating area of 50 x 13mm and a round cast aluminum face plate. Although designed to be used with either the F5 or F6 bass/midrange drivers in a small 2-way system, it is also well suited for 3-way applications. Recommended second order crossover cut-off frequency - from 3kHz.

HiVi RT1C-A Planar Isodynamic Tweeter is rated 4.2667 out of 5 by 15.
Rated 4 out of 5 by from Good SoundReplaced a broken tweeter and evened out the one I replaced last year.

Rated 5 out of 5 by from Solid performerI have these in a pair of MTMs that I keep in the garage. They are exposed to the elemements on occation, intil I can wheel them inside. Humidity is crazy in Baltimore.I have them matched up to HiVi aluminum mids and twin dayton QT-305s. It rocks. People laugh and say, "Your garage system sounds better than my living room"These tweeters do work quite well in a large soundstage, outside even.

Rated 5 out of 5 by from PROVEN FOR 13 YEARSI built an DIY version of the Swans M1 using this driver with the F5. The combination is greater than the sum of it's parts. The M1 has been in production for 13 years, and at $850/pair demonstrates the quality and popularity of the two drivers. On its own the RT1C tweeter is very accurate and not always mentioned, very low distortion. For the price their isn't any other tweeter that comes close. When I built my speaker I crossed over at 4000 Hz, but I think you can be safe at 3500.

Rated 5 out of 5 by from great performance if you wire it right!This is by far one of the best value tweeters you can buy! I love everything about them but they are made by HI-VI the makers of the Swan speakers. Ok I was reading where in another review that his tweeters were not as "loud" as they should be. Well it depends on the crossover frequency and type of crossover you are using whether 6,12,18,or 24. I contacted HI-VI and learned that these tweeters are marked (neg,pos) out of phase due to the fact that they recommend a 12db crossover which will put your signal 180 degrees out of phase so to correct phase issues they were marked out of phase which makes sense but a master speaker builder such as myself would appropriately change phase depending on my crossover im using. Anyway very thoughtful but could have stated it in the manual. So if these dont sound right try them out of phase. These are a great find and dont be afraid to play around with the wiring you wont hurt anything!

Rated 5 out of 5 by from Highly RecommendedI am stunned that a tweeter at this price is able to deliver such high performance. Very smooth and extended response, especially for a tweeter. Best of all, impedance is virtually resistive.

Rated 4 out of 5 by from Good tweeterTried a pair of these crossed at 3500hz in small 2-way speakers. I really enjoy the sound of these tweeters. Clean and effortless sound. My only complaint is one had a resistance almost 1 ohm higher than the other, about a 20% difference. Since I am somewhat new to speaker building, maybe this is not uncommon, but I think it suggest quality control issues in manufacture. That is my only gripe, I will definitely use these again, I like them better than other tweeters I have used.
