Product Details

Selenium ST200 Super Tweeter

Selenium's ST200 super tweeter offers outstanding detail and clarity at the highest frequencies, without harshness. The ST200 may be used individually in lower power systems, or arrayed for increased coverage and SPL in higher power systems. Thanks to its bullet-shaped horn design, the ST200 offers a longer throw 40° x 40° dispersion, and the plastic injected housing is stable and durable. The phenolic annular diaphragm is long-lasting, cost-effective, and more natural-sounding than metallic diaphragms. The use of high-temperature materials and adhesives improves power handling and produces exceptionally high acoustic output.

Specifications: • Power handling: 70 watts RMS/140 watts program (above 5,000 Hz) • Dispersion: 40° H x 40° V • VCdia: 1.75" • Impedance: 8 ohms • Frequency response: 2,000-20,000 Hz • SPL: 105 dB 1W/1m • Magnet weight: 7.72 oz. • Dimensions: 4.88" H x 4.53" W x 2.4" D. • Weight: 1.65 lbs.

Selenium ST200 Super Tweeter is rated 4.4706 out of 5 by 17.
Rated 5 out of 5 by from Great Home Stereo TweeterI bought two of these a couple months ago and just used in my latest system.Used with a 6.5" Goldwood for a mid/woofer and a sub powered Dayton 8" with a 100 watt sub amp. Like a by amp design. This tweeter is so bright yet smooth. One of my solutions to home theater application and music too. I just ordered four more.Just one concern with the design. There are four square openings that prevent an air tight seal so if used in a sealed or base reflex design, something to design around. The sound performance is well worth the additional work.

Rated 5 out of 5 by from Polarity QuestionsI finally found the minuscule polarity markings on this tweeter. (See Photo) Oh and by the way, these tweeters are amazing, transparent, and a perfect fit for pro-audio 3 or 4-way applications.

Rated 5 out of 5 by from sweet tweet on a jbl cf 150first of, i'd like to thank Eric at tech support for confirming the q's i have on this tweet before installing it. i was sent an out of spec tweet, ordered a pair, and explained to him, about the unusual lower ohm rating on one, and he immediately set me up with a replacement one. great servce imho. mounted this horizontally on a jbl cf 150 3-way cab. no harshness at all. great sounding tweet at a great price. now, it's time to get the crown amp out of its hibernation.

Rated 4 out of 5 by from Tweeters for some Bose 901First, I am just a dabbler. My main rig is two pair of "original" Bose 901 (series I/II). Sometimes you miss the top octave. With these tweeters (and a MiniDSP and a 2nd amp) it is easy to biamp the system to taste. Right now I get good results with the tweeters getting everything > 5 KHz. Tweets are not even in a cabinet: just place them where they sound best. Mounting can come later (if at all). I bought them based on the reasonable price, and also the other reviews you'll read here. I only give it 4/5 stars because you can spend a whole lot more, but what they cost is very reasonable for old Bose -- closer to a PA system (consider the 802) and either loathsome or merely good, depending on how much of a snob you are!

Selenium ST200 Super Tweeter

I'm thinking of replacing some lower output dome tweeters in a line array. I'm at ease with the crossover I currently have, but matching the tweeters' higher output will require (I think) an L Pad. Which L-Pad do you recommend?

Asked by: DAVE4154
A 50 watt mono L-pad will work fine for this driver.

what db 12,18,6 should the crossover be?

Asked by: samy boy
This is designed to be crossed over at 5 kHz or higher using a second order filter.

I thought I looked thoroughly through these posts to find something about polarity. There are no + / - markings on these tweeters.  I was hoping that someone may have pulled one apart by now and did a low voltage diaphragm pop test. Any news?  

Asked by: speaker guy
Answering my own question, I found very faint polarity markings under the connection pins by bending them down. Looking at the back (magnet) of the tweeter with the pins down--the pin on the lower left is + // See review comment for photo.

Can these tweeters be used on my Klipsch KG 4.2 speakers. They have Horns, and the tweeters need replacing. If these will not work, do you sell ones that will work?

Asked by: louie123
These are not intended to mount to horn lenses. They are stand alone supertweeters. It is best to start by checking the way that the driver mounts to the horn lens

Crossover point on these is 5k.... what size cap should i use inline with it... and if i put it on a car amp... does it matter if the amp has full range on?

Asked by: jtamrkg
I usually recommend the high pass 2nd order in line filter for these drivers. amp playing full range will not matter with that filter in place.
