The foam is glued inside to the back cover of the compression driver. Also, the titanium diaphragm is coated with aquaplas for damping resonance, within the diaphragm. See the link below for a well engineered titanium compression driver.Hm. The diaphragm seems to have a Ti suspension, rather than something that would allow for more excursion. IMO/IME this tends to lead to greater possibility of breakups in the audio band. Kapton can be used as a surround to improve that...

mozartfan OP Worlds finest tweeter Na, these are, diaphragm’s are lighter than air, therefore the best response time with least distortion, may not go as loud as some. https://forum.audiogon.com/posts/2149743 https://www.ebay.com.au/itm/Magnat-Plasma-MP-02-ion-tweeter-massless-air-plasma-speaker-Plasmahochto...

Seas , Scan Speak has no tweet in their inventory that can match a high quality compression tweeter. If you want realitic, true , not fake high fidelity highs, Compression Tweets are your only choice. Key word here is high quality , these will cost ya. But then I can get the DavidLouis compression horn with a gorgeous wood horn for just under $500 pair, Which is less than Seas, Scan Speaks high quality tweets. Dome tweets have no future. Troels Gravesen continues to employ out dated tweets in his designs. Troels is old school A 21st Century Audiophile seeks and desires new school technology. |
@mozartfan, ''Here on YT , I am not sure where the tech geek is placing the foam?'' The foam is glued inside to the back cover of the compression driver.

I like most planar magnetic speakers too. Many, such as Magnepans, are quite reasonably priced for the sound they deliver. Other types of speakers have examples that I like too. But, all speakers have limitations so it is a matter of different listeners having different priorities. For delivering a full, lively sound at low volume levels, nothing beats a really good horn system or a high efficiency system utilizing a full-range driver (either used as a single, full-range driver or as a wide range driver in a multiway system). Planar magnetics tend to need a bit more volume level to come alive. Both horn-based systems and planar magnetics tend to not deliver quite as much punch in deep bass as more conventional speakers, but, I like their tonal quality and clean sound (most horn systems use conventional bass drivers so they could be made to have deep punch bass, but, to match the speed and clarity of the compression midrange, most use very light weight cones with limited excursion and this reduces deep bass capability). What I particularly like about horn-based systems, and other high efficiency speakers, is the ability to use low-powered amplification. I find that low-powered tube amps to sound substantially better than their higher powered brethren. Most solid state amps sound a little flat, lifeless and unengaging to me, particularly at lower volume levels. The solid state amps I've liked the most were also low-powered amps from First Watt. |
Horn guys go whacko. the stuff they do.. I played for 25 years. The number of combinations I tried was NUTS.. It never stops. I finally settled on small planars/ribbons. Because of the prices, quality and speed of planars/ribbons, it was an easy move. Left the whole "hunt for the sound" behind.. Horns!!! Regards |
I've heard many fine examples of compression tweeters and midrange drivers, some of which employ titanium diaphragms (my speaker came with a modern titanium diaphragm compression midrange driver with alnico magnets, but, I switched that driver out for a much older compression driver that has a bakelite diaphragm. This midrange driver, a Western Electric 713b, is one of my favorite compression drivers. I also like the Western Electric 555 and the G.I.P. Laboratories' clone of the 555, but these add the complication of requiring a power supply for the fieldcoil magnets. Perhaps the best sounding compression tweeter I've heard is the G.I.P. 9501; it utilizes, I believe, an aluminum diaphragm, and costs a staggering $60,000 for a pair of tweeters (not including a power supply for the fieldcoil magnets). |
Don't fully understand the mechanics of this article, not important, what is important is that i made the discovery via research. What tiped me off is I figured if DL offers this TI horn , must be something special about it, inspite of a audiophle friend who adivsed to avoid like the plague, he's heard TI horns and hates the performance,,so i did some resaerch and found he just might be <,biased opinion>> https://en.wikipedia.org/wiki/Compression_driver Here on YT , I am not sure where the tech geek is placing the foam? At the entrance of the horn? Guess so. Sounds better with the foam pad.. https://www.youtube.com/watch?v=-_vob83fclA&t=219s |
