Pyramid TW47 Heavy Duty Titanium Super Tweeter
Pyramid TW47 Heavy Duty Titanium Super Tweeter is rated 4.0 out of 5 by 11.
Rated 4 out of 5 by from These are crisp !I bought this & some woofers for a center channel project as I can not afford the Klipsch RC 64 II ($1400 ? I don't think so...). I am so happy I did. They are a bit overpowering (I'll add an L-pad to limit the highs at some point). I have it crossed at ~6500, 18db butterworth. I tried lower but sounds raspy. Unfortunately now I'll have to replace (buy or build?) front mains... makes my Boston's sound "not so sweet" as I originally assessed... Waaa...

Rated 1 out of 5 by from Better to Buy a $4 Piezo: Low Output, Rocky ResponHuge disappointment, based on what I expected after reading other reviews on this product. It does not come close to a JBL bullet. It's 22dB LESS sensitive than the JBL 2403 that I have recently tested, and about 8dB less sensitive than this $4 piezo (left of photo) which I bought in 1976.The response is the most rocky I have ever seen from any tweeter. +/-13 dB over it's stated operating range. For reference, the JBL 2403 was flat to within +/0.6dB over much of its range. The TW47 is all over the map and doesn't even have one octave that is flat enough for hi-fi use.I would not recommend this tweeter for any application. It's not sensitive enough to use with PA-level sensitivity speakers. It's not flat enough for hi-fi, so that leaves them with no territory in which they'd be useful. The old addage "you get what you pay for" rings true with this product. With the exception that the $4 piezo will outperform this tweeter.

Rated 3 out of 5 by from closes to sounding like a 2402 JBLFor the $$$ spent can't beat this bullett tweeter. There are no specs, but I measured a ruler flat 4k to 16K when flush mounted. These don't roll-off after 10K like Pyle Pro stuff. I thought Pyle was all junk but this tweeter is best bang for the buck. You want multiple units if you want off-axis response.

Rated 5 out of 5 by from Great tweeterThis is a great tweeter for the price. Very high output, crisp and clear. The included capacitor will get you started, but I would recommend adding a real crossover for best results.

Rated 5 out of 5 by from Excellent for home theater!Built main and surround speakers utilizing these tweeters and they are very smooth when crossed over at 5K. For a JBL 075/2102 knockoff, these are nice units, and they are very clean at high SPL. They are well built, with die cast mounting plate and 4-1/2 lb magnet. They complement the Selenium 2" throat midrange drivers very nicely.

Pyramid TW47 Heavy Duty Titanium Super Tweeter

I'm planning on Pairing this tweeter with a single Selinium/JBL 8MB4P 8" low/mid driver in four small line array cabs. I've chosen the Eminence X-overs which limits me to either a 3500hz or 4500hz X-over point. What are the pros/cons for using either freq

Asked by: sterling7
This horn will work with either crossover point, but I would cross the 8" mid as low as possible, so the 3,500 Hz option would probably be better for this application.

A couple of questions

First of all, would this twitter be suitable for PA use?What's it's coverage? (Is it 50°?)If it is capable of PA use, how would it perform? Would it be a good match with 6" Dayton Drivers (Two Daytons - One TW47 per box)? Or would it be too much?
Asked by: XENGS
Yes this tweeter is designed for PA use. Generally something like a floor monitor where directivity is a high priority, these tweeters do not have a wide dispersion although we don't have a number we can associate with it. These would worok well with the Daytons but they will need to be padded down a bit.
