Beston RT003C Round Ribbon Tweeter
Beston RT003C Round Ribbon Tweeter is rated 4.25 out of 5 by 4.
Rated 4 out of 5 by from One of my favorite affordable tweeters!I've used the RT003Cs in a 2-way and 3-way and both sound excellent. If offers a sparkle and airiness that's lacking in tweeters in this price range. It has a bit more sibilance than some nice domes (and my ears tend to be more sensitive to those frequencies), but it's hard to find much other fault with these. It gives a nice intro and teaser toward what true ribbons can do at a small fraction of the cost.As mentioned, the tabs can break off. I surprisingly was able to fix one that I broke by scraping off some of the solder mask and resoldering. It was difficult to say the least, but doable. Just make sure not to push too hard on the tabs.The RT003C is now one of my all time favorite affordable tweeters along with the Vifa NE19/25-series which are great domes. I'm hoping the RT003C go on sale again as I'd like to pick up a few more.

Rated 4 out of 5 by from Nice...butNot much for writing reviews here, but thought I would warn, the tabs are extremely easy to snap off at the thinner than wafer thin housing attachment...beware! Doing so could ruin the tweeter, no way to re-attach.Performance is otherwise quite good, flat 6 ohm impedance is easy to work with.

Rated 5 out of 5 by from Pleasing, inexpensive, and accurate.The horn-loading offers a recessed acoustic center to better match midbasses for better lobing and time of flight. High energy Neo makes it lightweight. 3 components for an easy xover of 3.2kHz approaching a BW5 rolloff make it simple to implement. Surface-mounting makes it a snap to install, and you can decrease center-to-center spacing of drivers by overlapping the adjacent unit when mounted.The sound is pleasant, even though it does have a character all its own. Very transparent and top-octave extension is excellent, so this little booger sounds great!

Rated 4 out of 5 by from Detail and sensitivityThis ribbon can keep pace with any tweeter. My hearing is lacking at the scale this driver is capable of, yet, I clearly hear, separate intruments played at the same range, (cymbals, bells, chimes) with the detail and precision I expected. Each in turn has an equal source. In other words, the orientation of the driver (phase corrected and horn loaded) creates a very large soundstage, to the very edges of a 12' room with the cabinets 3' off the ground. The tweeter easily keeps pace with a 6.5" woofer, and does need a protection crossover, or very careful management of the amplifier. Most audiophile amplifiers are in the scope of this driver with a 3.3uf however a better solution is the 18db/octave suggested, and crossover point of no less than 3520Hz

Beston RT003C Round Ribbon Tweeter

Removal of bezel / horn / phase plug possible / beneficial?

This is one of only a few small round planar tweeters, and at least on paper, offers the smoothest response. I'd love to use this to replace the roughly 1.4in outer diameter tweeter in a BMW automotive application, if it would survive a bezel/horn-ectomy. Anyone have any idea how removing the plastic phase plug and entire horn-like bezel would effect the response and dispersion? Might the mild horn loading and phase plug be responsible for the flat response vs other similar round planars? (SLS PRD100, apexjr buyout round planar) I only ask because a couple reviewers here reported excellent results removing the planar driver itself from a couple other models of semi-horn-loaded planar tweeters.
Asked by: emaxon
This tweeter is assembled with adhesive so removal of any specific part like this will be very difficult and likely not beneficial at all. The phase plug is likely attached to the center of the diaphragm and removal of this would be nearly impossible without damaging the diaphragm.

What would a crossover look like for using this Beston tweeter as a stand alone SUPER Tweeter?

You're the expert but I was thinking of crossing it at 8 or 9 KHZ. Would that work or do you have a better suggestion? From what little info I could find, I was also thinking going with a 3-way (-18khz). Can you find out or help narrow this down? I think a lot of folks out there may find this helpful for building a inexpensive Super Tweeter since this tweeter goes up to 40khz - right? I am wide open to any further details or helpful information on this - thanks! TW

You will need a 1.5 uF cap and .25 mH coil for an 8kHz crossover frequency.
