Selenium ST200 Super Tweeter
Whats the polarity?
the terminals aren't marked for polarity as mentioned. do you know which terminal is which
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?
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

Do these tweeters require a crossover?
Yes these will require a crossover for protection.

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
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?
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.

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
The orientation of the terminals is not critical. How did you check the impedence? I am sure they would be the same.
