[quote user="haralanov"] So the tweeter is always needed. The bad thing is it deforms (in 99,9999999999999999999% of the cases) the perfectly round audio window, formed by the midrange channel and "pull" some notes sometimes at its axis. These are of...

[quote user="Romy the Cat"][quote user="drdna"] You are correct, though I believe the subwoofer covers only below 35 hz. [/quote] So???[/quote]So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say S...

Actually Goto does not have default 5-6-7 way systems. I have seen that they recommend 4 ways systems. Definably in the fields the dealer and distributor load their ignorant customers with as much drivers as possible selling them 55 ways systems.&nbs...

[quote user="nietzscheflake"] I am also thinking about how to get that headphone sound in my house and am contemplating the horn route… [/quote]
It ‘s fine but never forget that the imitation of headphones sound is NOT something that need to b...

[quote user="Jorge"]I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As ...

The Loudspeaker (Troels Gravesen project); a report started "too soon" because they've taken sooo long to build, and they fired right up (first try), and they already do Music!
For some time (at least a decade) I thought about
building a ver...

Principally there are many many theories and papers about ports and how they must be calculated/constructed/placed/used. But none of these theories explains the relation of port design to the SOUND. That’s the reason why so many engineers get s...

[quote user="floobydust"]As Romy pointed out, having high gain is not the same as power. If you're only barely cracking the volume control on your amplifier or preamplifier then it should be obvious that you have more gain than you need. If you're p...

well the way not to create problems is have a giant electrostatic panel.

[quote user="Markus"]Or perhaps he simply likes it to sound that way? You pursue one sonic ideal, Mr Sakuma obviously pursues a different one. The sound level - does Sakuma play louder or softer than you? My guess would be softer.[/quote]
Well, it w...

[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="Paul S"]All I want is wide-range drivers as fast as a Lowther DX4 [/quote]Paul,
I have listened DX4 driver. In my view
this fastness that you report is completely artificial and absolutely non-musical
as it does not have any relation...

[quote user="drdna"] I know all the compromises involved with the EdgarHorns, I have heard them when I visited Bruce Edgar in Gardena, and they were pretty good compared to most of what is out there. I realized that I would likely never be able...

Mani,
I would leave the subject of DSET/horn setup for another thread and would drop a few words about Zu Druids. They are not the speakers that I would ordinary comment but since I have a local guy with Zu Druids and I had a chance to hear th...

You are right about not compensating for recordings. Seems we've had this discussion before. So many variables.
Sealed box, horns, crossover slopes, and points, drivers and their various qualities,

[quote user="Romy the Cat"]To me an “installation”
is a complex set of measures and arguments that converts a listening space into
sound expressive space. [/quote]
Of course it is, well said!
Too bad not everybody understand that...

[quote user="Romy the Cat"]I do not disagree with
it but I would certainly question the practicality of it alone with
cost/benefit ratio. I think if the identically amount of effort would be spend
for other aspects then the benefits would be highe...

Cat, I’m
very disappointed by the fact you missed to answer my important question. I
really hoped I’ll get the answer from you…

Yes, proper upperbass is what I am l longing for. In my current system, folded horn going up to 350hz is not satisfying me and was the starting point of this project. It colors and kind of covers up the sound of big bands and orchestras...

[quote user="Paul S"]I recieved and accepted an invitation to hear an earlier version of the Cogent speakers, and I was subsequently asked for a considered opinion of the sound. I guess the designers had read from my posts various criticis...

[quote user="drdna"]Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned. Looking at the phase of the individual drivers and listening to each of them individually revealed that ...

[quote user="rdrysdale"]Romy, I just got a Vitavox S2 into my shop today. I notice that it has a very heavy stainless screen on the front, do you leave the screen on when using the drivers? It looks like it restricts about 50% or more of the thr...

Head today to another local audio guy who listen to my new
configuration. The reaction was fascinating. He was asking: what the hell I had
done to midrange? Of course, I did nothing, but the question was very accurate.
A lower mid-range changed ve...
