Product Details

Beston RT002A Ribbon Tweeter

A ribbon tweeter's radiating surface approaches the theoretical ideal of a zero-mass audio source. The articulation, attack, and sonic transparency are quite impressive, and the diaphragm's monolithic shape and orientation provide a broad horizontal and tightly controlled dispersion characteristic, which is ideal for many listening environments. Beston's carefully sculpted waveguide faceplate further improves the tweeter's linear emission of smooth, extended high frequencies. Beston's RT002A features a laminated aluminum diaphragm, driven by a compact and lightweight neodymium magnet. The driven radiating surface's mass is usefully low, and contributes to the tweeter's superb range, efficiency, tonal neutrality, and transient response. The motor, diaphragm, and carefully controlled horn loading are skillfully integrated to create a perfect balance of sensitivity and wide, even dispersion. Great for MTM designs. Achieve studio monitor-like audio precision with your next high-efficiency speaker project! A third order (18 dB/octave) or higher crossover is recommended to achieve maximum power handling.

Beston RT002A Ribbon Tweeter
Beston RT002A Ribbon Tweeter is rated 4.619 out of 5 by 21.
Rated 5 out of 5 by from Beston RT002A Ribbon Tweeteri paired this RT002-A beston ribbon with the woofer using the Dayton Audio XO2W-2.5K 2-Way speaker crossover to convert the B-652's into my studio monitors.  i would have to say this speaker sounds  spectacular!  the only thing is its power handling and efficiency are not as high as i'd like.  obviously a combination of the components.  but at the same time, this speaker sounds better than ANY other speaker of i've owned.  these speakers flank my tv screen and i SWEAR when i'm right in front of my tv, the sound appears to be coming from straight out of my tv.  it's an effect that i have never experienced before.also, whereas the original components in the B-652 sounded flat / dull, this model has full, airy sound.  the beston tweeter sounds sweet!   this is my first time using a ribbon tweeter and i don't think i will ever use regular tweeters again.  the RT002 completely fills my room, and i can hear things in music that i previously did not hear.this is an EXCELLENT ribbon tweeter for the price, plus it has good power handling.   anyone looking for a real good ribbon tweeter that's not expensive, i would highly recommend this unit.

Rated 5 out of 5 by from Great replacement for the Martin Lofan thin film Tweeter Center Speaker.It won't fit in the hole where the thin film tweeter was so I just set it in the hole and used longer screws. The Beston ribbon tweeter is sealed in the back so it didn't matter. I was able to put the cover back on. The tweeter works like a charm. It handles greater power than the original tweeter. The sound was identical. I didn't need to add any resistor and it works like a charm. Great speaker. It doesn't crackle on high volumes and mates perfectly with the rest of the drivers in the speaker. Great value.

Rated 5 out of 5 by from Excellent performance at an affordable priceMy first time building with a ribbon tweeter, and am extremely pleased. Although I built each of my units around two Hi-Vi M8N woofers and an M5N midrange, the Hi-Vi branded ribbon tweeters were, at the time of order, too pricey for my budget. So, I compared specs on the Beston RT002A and concluded it would be a good fit with my chosen 3kHz crossover point. As it happens, the unit has excellent response and imaging while providing a nice aesthetic finish on the cover-less layout I had chosen.The magnet construction on the back is a little bit awkward and made the mounting hole a bit difficult to cut without overshooting the perimeter of the horn baffle, but with a little patience I was able to work out the dimensions and cut accordingly. I would gladly buy it again.

Rated 4 out of 5 by from Restored JBL 216s with theseI removed the woofer and tweeter from two old and heavy JBL 216s (ported) and put the Beston RT002A Ribbon Tweeters in along with the Dayton 7" aluminum cone woofers, DA175-8. The ribbons were 7dB more sensitive than the woofers and 6 Ohms instead of the woofers 8 so I put 5.2 Ohm resitors on them and used the existing 2nd order 4K crossover. They've been getting broken in for the past two hours and I must say I'm very pleased with both of these. It's my first experience with ribbon tweeters and I can see why folks like them. Very happy and will buy these again, when they go on sale. Matt Cero, Seattle, WA

Rated 3 out of 5 by from a little brightThis was my first ribbon. I used PEs suggested crossover design to go with my Tang Band 6-1/2 woofer. I found that these tweeters are harsh and a little disturbing to listen to for more than a little while. I 'll go back to soft dome tweeters. Just my opinion.

Rated 5 out of 5 by from Supprising horn ribbonI was a little worried when I got these that they wound perform near as good as I wanted them to or they wouldnt match with the Dayton Larger ribbon.Well I was wrong these tweeters are outstanding They are clear crisp and match the Larger Dayton model when used in conjunction with other speakers that are loaded with the Dayton. Im conciderign now usign this tweeter in my series of tower speakers that use horns as this has a waveguide flare but sounds a lot smoother then the horn we normally use. This is a well built solid tweeter and sounds as good as you expect ribbons to sound. I have no compaliants with its perfomrance as well as attractive looks. An over all winner!

Is the backplate removable for using in an open baffle?

Asked by: Jeff K.
YES IT IS REMOVABLE ,BUT NOT FOR OPEN BAFFLE OR BI POLAR USE AND THE BACKPLATE HAS A LARGER MODEL TOO FOR HORN LOADING

mounting

does it matter if i surface mount these onto my cabinet or is it best to flush mount it like i did with my mid-woofer?
Asked by: jalng63
These were designed with surface mount in mind, as evidenced by the aesthetic roundover on the front edges.

can this be used in an 8 ohm set up? if so. how? and im wanting to add these to my fullrange setup,do i need a high pass crossover? thanks in advance.

I USE A 2 OHM 5 WATT NON INDUCTIVE RESISTOR ON THIS TWEETER TO ALIGN IT TO 8 OHM X'OVER

if I wanted to build a two way speaker, would this or the compression tweeters attached to a horn give better sound?

Asked by: jalng63
First you have to define "better sound". I believe what you are asking is about a wave guide not a horn. The most recent research seems to indicate how detrimental early reflections are to sound quality. It is inevitable that horns will have early internal reflections due to the boundaries of the horn itself. A wave guide is a better way to go. The new Seas Dtx tweeter is a waveguide with a patented shape. By carefully causing difraction at set distances they are able to achieve constant directivity. The is similar to what Emerald Physics does with its wave guide. As far as a Bestron ribbon. I don't recomend it. The only ribbons I have heard that I like are the Raal and the Raven. These are very expensive. Check the output and distortion of a ribbon if you crossover anywhere under 4 k the ribbon runs out of excursion very quickly and the distortion goes up. If money were my concern I'd go with the Seas Dtx at $50. You won't be disappointed and can crossover as low as 2k with a 4 order crossover. If you can afford more and want great sound look at the Ess or Aurum Cantus aerostriction units. Sorry you get what you pay for. Good luck Ralph

Off-axis response?

I'm contemplating using these in my car in the A-pillars. In order for them to fit, I'd have to aim them off-axis somewhat due to the 4"X4" horn. Does anyone know how well these perform off-axis & to what degree?
Asked by: kfish323
Being horn loaded, these should have very good off axis response, and as far as I can tell using the pair I have on top of Dayton B652s, their dispersion is excellent. These should work very well for you.

Can i use these ribbon tweeters for a car audio system?

I presently have 2 Pioneer bullet tweeters (no crossover). If I can substitute these ribbon tweeters, what is the recommended product to crossover?Thanks,
Asked by: dlautner
There is no reason you couldn't use these successfully in a mobile audio application. Just keep in mind that the impedance is 6 ohms on this ribbon, and calculate your crossover accordingly. I've referenced a prefabricated model below that would do the job, all things considered. Since the tweeter in question is 6 ohms, the 8 ohm crossover design would effectively cross it about half an octave higher, around 4.5kHz or so.
