It is incredible how stupid sometimes our audio steps are. A few days ago I was complaining that sound of my T350 tweeter suddenly started to bother me but it was no the problem with the tweeter but rather the problem with my own moronity.

I tried the driver and generally I do like it’s sound a lot. It more sophisticated then Linaeum, it is more noble tonally and alike the Linaeum is seamlessly melts with Vitavox S2. In fact I am developing recently a theorem according to which a compr...

HiSomething sounds very wrong - maybe something fishy about your samples?Take a look at Nelson Pass measurements towards the end of the following document:http://www.passdiy.com/pdf/KleinHorn2.pdfwhere it looks like the PTR9s have similar sensitivity...

I have a local friend of mine lent me PHY TW37 tweeter. It is French-made piezo driver:

Whoever followed the following thread:

Another very interesting observation that I discover today. Paul have mentioned about the improvement of bass. It was not a secret but what a secret, as least for me the TYPE of the bass changing projected to the precession of HF dialing.
OK, ...

Hi Romy,I see now you are throwing around the term "absolute tone" in a relative manner again :) . Why would you want to neutralize absolute tone and with a metal tweeter no less!! You are talking about a tweeter "absolute tone" offsetting a po...

I have to admit that although the Macondo “Water Drop Tweeter” sounds very good but I do not have that “shocking sound” that I got from the “Water Drop” during my initial introduction to it. I kind of always felt it and I thought that I get use t...

[quote user="noviygera"]Number one, that I'd like to run by you guys due to it's simpler nature and closer to reality execution is the idea I have been thinking about. No first hand experience with any of this.Say we use something like altec 1505b mu...

I am not quite sure why Paul came up in this thread with the subject of “ribbons sensitivity to... everything”. That is absolutely not relevant to the AHFS concept. el`Ol, the ribbons and AMT tweeter I feel absolutely identically wrong if to approach...

They paid attention to time-alignment, good - but the tweeters location near a large reflective surface might be problematic.It looks like a 1kHz tractrix horn to me (maybe 800Hz). I have one though it's from Stereo Lab....

[quote user="Jorge"]Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There...

Hmmm...
I like my tweeters +/- "matched" in terms of efficiency, but I am not starting out at 115 dB efficiency. Sure, headroom, practically speaking, is more than a mere luxury. However, is it really that hard to wring out a tweeter, and how muc...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

Welcome Sean19, Another member should correct me where I am wrong. There should be some tweeters that just start emitting in their proper frequency range and do not need a crossover. They might need a resistor so that they are volume balanced to ...

I asked my Japanese speaking friend to translate for me the information about the tweeter in that Brazilian installation. It is JBL UT-045Be, I never have seen/heard it, and so I presume many others… 25mm beryllium spherical diaphragm, 52mm circ...

I'm probably revealing my ignorance by even asking this, but I'm
curious to know if a field coil ribbon tweeter could be practical. It
occurs to me that if one could be made, it would be a lot safer since
it wouldn't be a black hole for magnetic o...
