[quote user="be"] Instead of defining the ULF range from the reproduced instruments, it is much smarter to do it based on the first resonance frequency of the listening room, because the frequency response of a closed room has a 12dB/oct rise in ...

[quote user="peter foster"]The station that I most listen to is 105.9 MHz that broadcasts from one location 50 miles away at 100kW power and that is detected by 2 FM aerials mounted as a parallel array with rotator and ~ 40 feet of coaxial cable to t...

Well, this concept of Defense Mode is good for superficial explanation (or for selling to ourselves own justifications) and I use to use it in past but I do not use it for a few years as unfortunately it is not what it is. The correction of “the wron...

[quote user="cv"] …..and I am not confident about the sonics….[/quote]
What might be very interesting also is to learn what DC coupling in power amps would do generally in term of Sound.
The first time I thought about it was a few years back when ...

After spending two weeks with high-passed Celestion SL-600 reinforced with external LF section I would like to make some observations. I had a single SL-600 monitor (I always tend to use one for assessment purpose) on it’s original stands in the very...

[quote user="Romy the Cat"]However, in audio the coordinate system is not geometry but hearing and human hearing is not equally-dimensional. Humans, juts because the position of ears on heard have much higher sensitivity to horizontal sound source he...

[quote user="Romy the Cat"]Still, I feel that methodologically it is not right
way to build a playback. [/quote]No disagreement from me on this point. This is all just a thought bubble for now. Even if I wanted to press go on this project based ...

[quote user="Romy the Cat"]Another this the I at this point has no idea why in my use
of ULF channels. I mean I do not use it as it does not sound right. This is strange
because it is VERY same ULD that I had before and that worked very well in my
...

[quote user="Paul S"]Romy, perhaps your ScanSpeak arrays are a +/- natural fit for mid-bass? If you used them for that you might also push them down a little until you got your ULF solution. The "nice" thing about this is, you might use something r...
|
|
Yes, Jessie, but in case you decide to go for DSET, would it be multi-channel Melquiades or anything else, then your consideration for type and topology of the lower bass would greatly dictate requirements for your DSET. If your lower bass channels r...

[quote user="jessie.dazzle"]In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. Be...

Well, it happened with me, one of my HH of my DAW, or as they call it “music server”, went down. It does not recognize by BIOS anymore, suck, it would be costly to recover data from there. Partially the most important files from there were backed...

[quote user="anthony"]There should be an 111dB tap
on the Lazy Ribbon, but perhaps you have tried that already. Other than
that, perhaps talk to RAAL to see if they can improve the sensitivity a little
more with a transformer change (or something...

[quote user="glaesemann"]Roman in a few posts you have made reference to the interesting topic of cable current loading. I'm keenly interested in your findings.[/quote]
Glaesemann, there is not a lot to talk about it. My observation showed that prac...

[quote user="haralanov"] Rakesh, during the last year, there were some very important moments in my own realizations about the methods of low frequency reproduction. I totally abandoned my Scanspeak bass modules and now they are resting in my gar...
|
|
[quote user="haralanov"] Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that...

Well, I kind of begin to think what kind LF solution I might
have in the new room. The ULF might be fun to load on the ceiling in the way
how I described above. For the midbass I most likely will go for the
line-arrays with my beloved Scan Speak 2...

It is highly unlikely that I will go for this project
For sure I do not care about the conservation efforts and I do not care about recuperation electricity back to grid in order to earn credit. I do not think the wind power is useful for me. ...

A week it trashing audio.
I finished with my client with wish I worked for a while, the contract with a new client kicks in 2 weeks and this week I do not work. Well sort of. This week is a big project on my aim – to reconcile the value of my...

With the project of the 6-chennal Super Melquiades is about to hit its final stage I might to review my summarizing observations. The 6-chennals Macondo is driven by 6-chennals dedicated DSET Melquiades, that looks like properly orgies for the job. T...

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

The question I ask is a bit more loader than what appears at surface. When people who do not know me ask me what I do I say that I involved into (or practice) High End Audio but saying it I feel that myself I have different definition than it com...

still not enough to produce an acoustical watt. (which horns CAN do).

That is a fancy one, with vacuum caps as I can see it. I do
not know about the practicality of vacuum caps – they have own pluses and minuses.
Still, that is nice crossover, a bit more complicated then I initially thought I
has to be. It would be ...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

I made today some interesting experiment and for the first time during my “fundamentals channel saga” I get some stimulating and very result. I find a way to mount the “low frequencied S2 driver” on the speaker’s axe way above the Macondo’s tweeter. ...

I had yes today a meeting with a rep from out local solar company. I am kind of greenish pussy and have a house with a big rood turned to south – so I was wondering to put in there a large array of solar panels. Massachusetts has a very wide coll...

Many people know that I run a side business doing wedding photography. During the 24 years that I have been doing the wedding gigs, and after over 950 jobs that I went through I kind of have seen all imaginable wedding bands. Certainly the “events mu...

Romy,
Thanks for the thoughtful writing... Sorry my response is not exactly "time-aligned"... I've been meaning to reply for the past few days, but my other life has been in the way...
