Do you have the speakers as pictured already in place, or at least in the form your beautiful rendering shows? I would recommend to try a mock up of this layout in your room and not proceed with the full custom build. For example, I don't think the a...

Yes, you are absolutely right.
If I make a much deeper cabinet and put many more drivers closer to each other
then I will have much more sensitive array. I do have 18 more of those drivers
and the idea did hit my mind. From what I have now an extr...

This weekend I was walking in my new listening room and did
some thinking how to organize everything. Unquestionably my first step would be
convers Milq LF section (bass line-array) from Midas accommodation to drive my woofer
tower, in a way how I...

It was very interesting experience today. My son have a birthday party and they decided to do it in our house. I was obliged to play Harry Potter in a big screen for 15 kids, so it's naturally make me too move all the speaker along the wall...

For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

I would like to point out something that is going on here that I found truly remarkable.
For advanced people ho play with horns there is no second opinion that the vertical array, the Macondo/Cressaro-Gamma type of architecture, is THE ONLY one tha...

Chris, I did ask myself the same question: perhaps my given PTR9 is demagnetized. I called the last night to the owner of the tweeters and he said that he uses them for 7 years and they driver should be fine. He also expressed a lot of doubts if the ...

It is my understanding that the only reason to make a ribbon bigger is to get it to go lower in frequency. I don't know how Arum Cantus configures their G1, and I have not heard it so I cannot say if it is their "best" pure HF driver rather tha...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...

We enter a complicated region as the lower driver we go the drivers could be used for different purposes and it is very hard to generalize. A 10-incher might be MF driver and LF driver. In my past I experimented with few MF 10-inchers, including some...

i certainly know a lot of 'audiophiles' with a vast array of gear-- some good, some bad -- but i think there are a variety of reasons people are so confused about what constitutes good sound.one of the most heinous- outside public opinion- ...
|
|
Yes, both ends of the spectrum are tough to integrate with a quality MF.Of course, electrostats have no "push", but they seem to do all right (understatement) just supplementing way up there, in an array.The thing is, the "big" ribbons and 'stat...

Well, I still do not know what the tweeter solution would be. I know exactly what I want to get: to soften the S2 driver and get HF extension but without introducing HF noise. I know exactly how it should sound I juts do not know at this point how it...

Thanks Gregm. It is interesting that I completely forgot the TAD PT-R9. I was looking at it 5-6 years back and spoke with AudioKinesis ‘Duke, who reportedly knows them well. My reservations that time were the very same as now: with 97.5 dB/W sensitiv...
|
|
But not everyone agree with you there, Romy.
If I could make the directivity reasonable constant through the frequency range....all the way down....
An array of tweeters is the last thing I would do....
cheers ;)...
|
|
Gregm, you see, the Murata tweeters have no sensitively and vary narrow diagram and that makes those type of the drivers unusable, even if to accept then hypothetically. With the resonant frequency over 100Khz that those type of the tweeters beg to b...

Hi Romy,
I've met musicians who understand music to a far greater degree than (I suspect) you or I ever would. I wouldn't however necessarily trust their judgement on matters relating to good playback. Some of them use quite appalling systems and ye...

[quote user="cv"]Not to start a pissing contest, but how are they wired (series/parallel?), and with what voltage across them? Something just can't be right; the makers spec is 88db / 2.83V, which is over 1W. Unless it's uniquely smooth room gain wit...

Hello chaps,
Another option thrown in there by Bud; always enjoy your posts even if I don't follow them 100%...Let me attempt to barbarically distil what you said into 2 aspects which are
1) The dielectric properties of the insulating materials2) M...

I have seen those old Telefunken, Siemens and some other 4” cone direct radiation tweeters, but I never tried them. I do not know thier signature and I do not know thier characteristics. The reason why I never cared about them, although I might be wr...

I do not know, Antonio. The Beethoven’s symphonies are divert it would be difficult to point out a specific performance but rather an array performances:

I have tried both SS and tubed PP with HF ribbons, but not until ML2s have I gotten the "calm HF" I wanted from the ribbons. I am still experimenting with the Audaphons, but they seem to do best from 4 Ohm tap. My little 2A3 SETs did...

Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

Paul, in my view the air-caps as an ultimate cap, the ultimate by own intrinsic topology. It is particularly the case for the 834P- like application as in there the cap is not biased by high voltage DC and gets constantly re-polarized. You see the pr...

The Lavry DA-924 and Sansui TU-X1 are on separate equipment legs/chains and only come together at inputs to the amplifier. They also are on separate uninterruptible power supplies that are on separate legs of our wall supplies. Also,...

From Alex's thoughts it seems like one approach might be related to/interfaced with the program itself, such as RIAA or FFRR, etc., etc., even though I think those "recommended guidelines" have been only loosely observed by recording e...

Be, there might be any number of reasons for listening to speakers more or less on or off axis, but I think in the case of drivers firing early across the axes of other drivers there are identifiable issues that can be heard as "problems" by some lis...

[quote user="Lbjefferies7"] Very good. Raal 70-20XR...interesting. [/quote]
Oh, yes, the 70-20XR is very interesting. I did not have this driver but Alex allowed me to experimented with some elements of it’s design in context on my “Wa...
