Another e-mail on the Forum recommended a single 0. I have to say that if anything, these tweeters are under-hyped.

So I did as they did, and mounted mine on top of the cabinet, angled at the listener, with some Blu-tack. Instruments have more “air” around them. This explains the VERY relaxed treble. The Fostex FT17H horn tweeters came neatly packaged in a small cardboard boxes.

However, foste are too big to be mounted on the current tweeter position. Hey, you idiots reading this, stop spoiling our reputation!

I haven’t heard so much treble from my system! You see, the Fosetx Dynamics main 12″ driver has a sensitivity of 97dB while this Audax is only 94dB.

Right out of the box, they look good.

So far, build quality of all Fostex drivers I have come across look really good. Still can’t hear much depth, but I reckon it’s more of a “room” problem. I haven’t heard much mention of how pretty they sound.


ft17n Haven’t done much on it, but swapping the only electrolytic in the crossover with a better cap yielded even better sound! I don’t have to tell you this new procedure is a P-A-I-N. Foshex in use now, is the non-oversampling variety, thus, there should be a The FT17H horn tweeter uses a shielded magnet. I was suprised to find it quite heavy, g 0. The overall weight of the FT17H tweeter is g 0. The build quality of the Fostex FT17H horn tweeter is good for the price range.

Seems that mosquitoes can’t stand this frequency probably some pets too.

The horn super tweeter offers a crisp high frequency response that extends out well past the audible range. The Fostex FT17H is an economical horn super tweeter with a frequency response that extends out to 50 kHz. The nominal impedance of the FT17H horn tweeter is 8 ohms making the horn tweeters easy to drive even with small amplifiers.

Ever since my Hammer Dynamics started singing, I have been having lots of fun. Reason being, too many credit card frauds. Since this Fostex has output up till 50kHz, there should be Included with the horn tweeter are mounting screws and a datasheet. Other than the “air” factor, it also seems to have more “body” and “feel” to it. The Fostex, at The FT17H horn tweeter has a high sensitivity, rated at The low cost FT17H is ideal for use as a rear mounted super tweeter.


Finally cymbals and hi-hats have more “body”. Provided that a crossover point in-excess of about 10 kHz is used, the performance is very good.

I got mine from Madisound but ordering through them isn’t as easy as before. The FT17H is ideal for mounting in an enclosure – front and rear firing. Upgrading every component in the crossover doesn’t sound good to me.

We have had good results with this tweeter using a first-order crossover in the 10 to 15 kHz range. Will fiddle around until I find a position I like. Every unit even has frequency response chart, specifications, mounting dimensions and configuration example.

I hear a wider, more open soundstage.

I mean, how many parts on earth do you have to keep on buying until you find what you like? I get too conscious of the treble! Noting that I hate sizzle or exaggerated treble. Heard that some commercial mosquitoes repellant utilize a 40kHz fosttex tone to “shoo-shoo” f17h away. No, not the sound, but the idea. Those guys on the Super 12 Forum is right.
