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.

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!

Rated 4 out of 5 by from exceptional valueMy ratingsvare based on price/performance ratio. I am using this tweeter in a high effeciency test speaker design with two inexpensive 10" paper cone woofers. Given the open body, the tweeters are mounted into a separate sub enclosure to prevent leaking and resonance.When properly matched to the other drivers, these tweeters exhibit a smooth yet highly detailed presentation. Much smoother than one would expect from this type of horn based design.Care must be taken with the mounting tabs as well as mounting in the cabinet. Should have a sub enclosure if being used in a cabinet housing woofers. Especially a sealed cabinet as it will leak.All in all....... a very nice product if you are looking for a high-E tweeter for a reasonable price.

Rated 5 out of 5 by from Rings my ears!Not only does it play back music with extreme quality, it gets very loud. And retains its quality throughout. Crossed at 4,000 Hz, it sounds very good. Great for studio monitors, mobile audio, or a home theater build

Rated 5 out of 5 by from high end musicality playbackyou can always hear the amount of money , put into production of a music cd. that being said , i recently purchased a pair of selenium tweeters. i was listening to an old cd . the clarity and natural sound from the selenium tweeters revealed sounds in the music i never heard before. i was pleased and surprised.

Whats the polarity?

the terminals aren't marked for polarity as mentioned. do you know which terminal is which
Asked by: Taylor
Unfortunately, we do not have a specification on this, and it's not an uncommon condition among modern drivers. If you're using a pair of the tweeters, simply follow the same convention for both, and you'll be just fine. For instance, as you look at the back of the tweeter, say that the left-hand terminal is positive, and the one on the right is negative. As long as both units are connected in the same fashion, they will be in phase. Using a single tweeter or a pair, listen to them wired one way, then the other. The way that produces the best result to your ear is the "right" way. You won't damage anything by wiring them out of phase, but one way may sound better to you than the other.

do you sell the diaphragm for the st 200?
Asked by: jose
One reason I love and trust PE is that they have the parts you need to fix your gear. Yes they carry the replacement diaphram and it is Part number: 264-348.To replace the diaphram simply unscrew the magnet, remove the old and insert the new diaphram. Replace the magnet and your back in business.Good Luck

Enclosure size

i'm looking at installing these into an enclosure for weekend use at car shows and get togethers. i can't find anywhere that says what a good size enclosure for these would be. any help would be grateful
Asked by: Mtopper
hey there Mtopper,these are, as you know, tweeters. when it comes to tweeters, they tend to already have an enclosure, which is about 0.5-3cu in, built into the driver housing. any tweeter that has no enclosure already is going to be expensive and very sensitive, likely too hi-fi for most if not all car audio systems. the only thing that i would suggest is that it be mounted on a surface with a few square inches around it so it can disperse the sound more widely seeing as it will be for your application in a car. hope this helped and have good fun installing these.

Has anybody been able to find T/S parameters for this guy?
Asked by: Jordon Gerber
I wasn't able to find the T/S parameters either. Fortunately, they are not variables I would relay upon in selecting a tweeter unless I were concerned to create or replicate standardized conditions. (I do find T/S of potential value when comparing larger speakers in some settings.) As I see reinforced in the comments, this is a smooth-sounding tweeter, made even more valuable by its low price. It is probably not the tweeter of choice for anyone who needs to integrate it into a complex system based in part on T/S parameters.

mounting options

hello, planning on using these to replace blown tweets out of a jbl cf150 3 way. can i mount this in a horizontal manner, where the spkr terminals would be sideways? also, when i received my pair, one is showing me 5 ohms, and the other is at 6.4. seems like the one with lower rating also is a return, as the plastic packaging is not factory looking as the other one. tnx
Asked by: crispa1
The orientation of the terminals is not critical. How did you check the impedence? I am sure they would be the same.
