Let's talk Tweeters!


Another thread which talked about specific speaker brands was taken over, so I’d like to start a new one.

Mind you, I do not believe in a "best" type of tweeter, nor do I believe in a best brand of speaker, so lets keep that type of conversation out, and use this instead to focus on learning about choices speaker designers make and what that may mean to the end user.

There is no such thing as a speaker driver without trade offs. Some choices must be forsworn in exchange for another.

In the end, the materials used, magnet and motor structure, and crossover choices as well as the listening room come together to make a great speaker, of which there are many. In addition, we all listen for different things. Imaging, sweetness, warmth, detail, dance-ability and even efficiency so there is no single way to measure a driver and rate it against all others.

Also, please keep ads for your 4th dimensional sound or whatever off this thread. Thanks.

Let me throw in an unmentioned ribbon tweeter.  Newform Research produces a 30 in and 45 in ribbon tweeter.  This is a true monopole line source.  I have owned a couple of module 30's including an no holds barred model.  Different radiation pattern altogether.
I would use it all the time but engaging the crossover in the preamp I use (Parasound P7) really diminishes the sound.
Sorry for being random Erik, but why does engaging the crossover in the preamp diminish the sound? 
Hi Sean!

For those who don’t know, the P7 preamp is unusual in an audiophile preamp for both having a pair of 5.1 channel inputs as well as pretty versatile bass management.

I think it’s a matter of the particular circuit choices in the P7, and not an issue of crossovers in general. It sounds dynamically compressed. To my ears, I don’t think Parasound took the same care in the bass management circuit as they did the rest of the pre. I felt that the sound coming out of my main speakers was just not nearly as transparent whenever the high pass filter was engaged.

This is NOT an issue i have with movies, but then all the bass management is being done digitally in the Oppo 103.

I probably could have tried running L and R full range, with the sub but meh... Instead I decided to optimize the Subwoofer, especially the EQ section, for movies, and it's fab.

Best,

E
I still like the old silk domes. The lighter the better, and good mathematics to match the power of the magnet to the moving mass. I often read Science Daily and one topic area is new materials. They are continuously coming up with thinner and lighter and stiffer materials, so I hope the speaker manufacturers are paying attention and ready to take advantage of the latest and the greatest. Don't forget laser vibrometers. Accuton has a driver that has no breakup at 5oooo hz. The biggest problem I get frustrated with is the lack of standards with recording. Signal quality all over the place.
