Product Details

Beston RT002A Ribbon Tweeter

A Beston RT002A tweeter's driven radiating surface mass is usefully low, and contributes to the transducer'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.

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.

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. Minimum recommended crossover frequency: 2,500 Hz

Beston RT002A Ribbon Tweeter
Beston RT002A Ribbon Tweeter is rated 4.5833 out of 5 by 24.
Rated 4 out of 5 by from Good tweeterI bought this tweeter a year ago. It is very clear and detailed. The plastic frame resonates, which is an issue that can be solved using damping material. I chose to keep using my Scan Speak D2905-930000, but will definitely use it in a new project.

Rated 4 out of 5 by from EXCELLENT if you can adjust for the bump at 15 KHzI'm using these in a speaker project with an 8-inch woofer with 91db efficiency. Unfortunately it sounded little too bright even for my taste. I'm running foobar with foo_dsp_xover and I was able to tinker around quite a bit with crossover setting and attenuation for this tweeter. I suddenly remembered the response graph and the bump of around 5db around 15KHz. Using software equalizer (foo_dsp_xgeq), I was able to adjust for that bump and I have to tell you that it sounds EXCELLENT NOW!I have another ribbon tweeter, Dayton Audio PT2C-8 too running on another speaker. Both sound great - a lot better, in my opinion, than many other dome tweeters. Here's a quick summary* PT2C-8 is a lot larger and has higher 94 db sensitivity.* Beston's is almost half the size and the stated sensitivity is 92 db (not considering the bump in 15KHz region) which makes it more suitable to pair with many other mid-range speakers.

Rated 5 out of 5 by from Crystal clear and extended response.My first experience with a ribbon tweeter, but compared to other types that I've used the Beston is very clear and nicely extended. I tried this model because of the power handling and frequency response, the impedance matched the speakers I wanted to use them in and the sensitivity was within 3 db. I ended up using an attenuation circuit to pad them down by 3 db and now they match up nicely. The sound is excellent.

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.

Would this ribbon tweeter be a good match/ replacement for a set of Polk Monitor 5jr ? I'm more interested in its matching the factory Polk crossover. As I'm customizing the enclosure so fitment is not an issue. Thanks in advance, Rob.

If I crossed it at 5 KHz instead of the recommended 2.5 KHz, will it have any effect on its power handling capacity? In other words, I'd like to use it as a super tweeter in a 100W RMS system but possibly crossed at 10 or 12 KHz - will it work? Thanks.

Asked by: Rajeev
This tweeter will handle its full power capacity regardless whether it is crossed at 2.5kHz or 5kHz. Yes it will work crossed even higher as a super tweeter.
