I think the most interning would be to learn what kind MF and upperbass drivers were used, particularly the MF. I hope they are not the German BMS drivers as it would be a major turn off. It looks like 2” throat, would it be possible that French folk...

The problems with Smart Grids
by B. Blake Levitt and Chellis Glendinning
How is it that so many intelligent, inside-the-beltway environmentalists are buying into an eco-health-safety-finance debacle with the potential to increase...

Ok, I did play today with the MiniMe. I have to tell that then it turn black I kind got soften with it does not look to me as large and violent as I initially thought. I made some measurement and some listening. I peaty much know what I want to be an...

Sorry, I should have said by now that my (15" Audax PR380M) bass units are FLAT to 38 Hz, and then they roll off naturally at 24 dB below that, meaning if I have 38 Hz @ 100 dB, then ~30 Hz is still >88 dB, and obviously 20 Hz is still p...

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

[quote user="jessie.dazzle"] I have not heard any other systems using Vitavox S2 drivers, but I know it is possible to get the S2 to generate on-axis unpleasentries. In the case of the system I am building, one can happily sit straight in the firing ...

Hi Romy - Do some research on the insulation and water problems of roofs in extreme situations (e.g. Northern Maine, Canada). We can have these same problems in Massachusetts in January and February. I had to deal with these painful issues at a qua...

To be honest, I think that ANY stereo system gets in the way of the music - regardless of the amount of channels.Let us jump back to the monaural records/radio years. At that time, we had one choice and were very satisfied in being able to play back ...

Romy,It's ok, I was just being a smart-ass about Fremer. Yes I understand that VTA is the angle that the needle hits the record and that the elevation of the tonearm base is how it is adjusted.Here is a picture of my turntable and arm:https://docs.g...

An audio guy contacted me today with and an interesting note: “can't put a piano in the same room as a hifi”. When I asked why he wrote: “scott's steinway sounding board would 'ring' like crazy. it was my theory about why his tannoys sounded even mud...

The Danley idea - or something quite like it - does look good for LF, but maybe less good for MF and up, I think.Which takes me back to the whole "point" of the imaginary "single driver"...Effing around with mix-n-match "systems" back in the day...

Yes, CV, I thought about it myself and I fine that this might be VERY interesting to play with. Unfortunately, or fortunately, I am months away from the position when I will be able to do it. The subject is devilishly interesting however. I think it ...

It is kind of strange – there is absolutely nothing to write at my site. I use playback dally, have a lot of new and old interesting music but I tend to write about it at other sites. From audio perspectives I have absolutely nothing what is doing on...

One more tip. The “least dynamic compression positioning” mostly managed by upper bass and bass channels while in the “imaging positioning” the MF and HF channels play more dominating roles. Therefore, if you use a typica...

"Architectual" (man-made) joists have some decided advantages over natural lumber, including excellent unit-to-unit consistency. Most residential "TJI" joists (as opposed to beams) are made straight and installed without an initial "crown" (manu...

[quote user="Romy the Cat"]So, what the concussion is. It is known that PP2000, as any switching devise, inject a lot of noise into power line from where it sources power. Apparently the PP2000 own filtration can’t handle the noise from the second PP...

"the Magico Reference" Samuel, how can i be subtle about this.. have you searched the sight for Romy's thought sabout the Magico or Marten designs? Link Have you read Romy's Audio Rules or the Knowlege Tree to know what the discussions here are about...

Hi Romy ,well I appreciate the reply anyway! I have been reading your many threads and yes some on the Lowther designs but as you know your writings are a large large volume also and I havent made my way thru them all yet. As far as my room I could b...

HI,Music is meant to create a feeling. Who is to say your feeling is better than my feeling. It;s all about sensitivity to feeling and the creation of emotion. If a sound (or a set of sounds) can create that emotion & feeling in you, then your go...

And you are right that it also has a regulator within the power supply. This is stated within the owner's manual but it would not allow me to copy it. They use rather convoluted language. Maybe this is the result of translation?To quote from the r...

Completely understandable. That's why it's fun! It's enjoyable to make something, study the results, make changes, and start over! That seems to definitely be the theme with horns from what you guys are telling me.So it sounds like I shouldn't expe...

Somewhere within this thread (or perhaps somewhere else) I have mentioned that my own playback systems last times was dead-installed into the DpoLS approximately 5 years ago. I kind of did not make a whole a lot of attempts with DpoLS since I was doi...

Are you saying that this behavior is behavior is characteristic for dried out capacitors? I need to admit that I know very little about solid state electronics and I have no idea how it ages. My amplifiers are 40 years old and certainly it would be c...

I put the Model 2 today in the system and configured my typical operation mode. I got another pleasant surprise. It looks like the Model One and Two has different DC offset pattern. Both use digital offset and both are not defeatable. Here is where L...

You might try the Foam Factory; they are easy to deal with, inexpensive, have online ordering, quick turn around and can ship anywhere.They are NOT a typical audiophile-oriented acoustic room treatment supplier. Nevertheless, they are equipped to cut...

Very good point - I will direct Martin's attention to this. Visually, it looks like he did an excellent job on the 340 Hz horns, and the 160Hz horns will be rolled off at 1k anyway but nonetheless, will see what he reckons. Actually, no need - I just...

I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; but I came to the concl...
