Selenium ST400 Super Tweeter Black
Selenium ST400 Super Tweeter Black is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Crystal sound Like no other I've experience!The Selenium ST400 Super Tweeter Black was used as a replacement tweeters on a Pro Studio cabinet that is part of my surround system since the original tweeters were damage. They are combined with the Eminence PXB3:5K0 3-Way Crossover Board 500/5,000 Hz. Super clean sound, you can hear every detail of even the the tiniest sound of a pin drop or wood burning as if you are physically there when watching a movie. As to just listening to music enough has been said. I will be making future purchase of this model tweeter for car audio integrations. Its amazing that even at very low volume it sounds so detail-like.

Rated 5 out of 5 by from All the performance you needI picked up 4 of these for a club re build. They out performed the mids and lows with superior clarity. For the club world you can have all the Sizzle you need. I've been building custom DJ and Club sound systems since the early 80's, this is my new preferred tweeter.

Rated 5 out of 5 by from Good AlternativeAs JBL has quit selling the 2402 bullet tweeter I felt this wood be a good alternative. I have a Four-way design with a 18",10",2" horn and used a one inch horn for the tweet. This is a fairly high efficiency system with JBL components. I was not happy with the high end and had trouble finding a tweeter with acceptable range and efficiency. This looked like a good choice so I bought four of them, Two for each side. I use them from 8000-10000Hhz and up, depending on the music. they really add that sizzle on top and the efficiency seems good. I had to turn down the high end by at least 6db.The only complaint is the location of the terminals-not the best but can be dealt with. Initial cost is quite cheap for the sound and the replacement diaphragms are less than $20.00 what a steal.

What is the best capacitor to use with this tweeter

Asked by: leston14
I would recommend a full second order high pass instead of a single cap on this driver. You can see a good choice for this below.http://www.parts-express.com/5-khz-high-pass-8-ohm-crossover--266-474
