[quote user="noviygera"]I have been thinking about how nice it would be to have have a good sounding DSP for crossover and delay functionality. I know this subject was covered here before but what was talked about is this DSP is not that good, and th...

[quote user="noviygera"]Could it be that the SoundDock gets the basics of sound reproduction right? And if the basics are attained without fussing around (and it matches your values of basics) then why trick yourself to search a better rightness. For...

[quote user="noviygera"] This is an interesting
concept but What does it mean to "load" and "idle" SET and
how is this accomplished without changing the speaker it's driving? [/quote]
The "loading" and "idling" in SET is

[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="noviygera"]I think most people, as audience find fascination in unusually capable performance of the performers, as in a live music event. So if there is no performer there is nothing to give homage to, really. Other than good reproducti...

user="noviygera"]Also you say: "In reality the driver is the
key"So let me ask for advice on suitable driver(s). This be my next step.
Need I select a size? Or driver with certain spec? For example lets say driver
"x" is good for this rang...

[quote user="noviygera"] Question, Romy:Why do you suggest to add the extension on the back, not the front, as B. Edgar suggested. He specifically commented that the MOUTH area is too small and said the throat size was OK?[/quote] Herman, the mouth a...

[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...

[quote user="noviygera"] Is there a pill for that too? Seriously, it would be very interesting to hear what solution you come up with because I have converted from listening music solo to a small number of audience (friends). So much that I listen by...

[quote user="noviygera"]Romy,What was the reason you were not happy with the last version of your midbass section? THe one with two Vitavox 15" per side. [/quote]It was not a last version
but rather a temporary test version. I used in undersized sea...

[quote user="noviygera"]You can get all the advice from the experts but you might as well start with something.
But at least with pro sound like VOID, Funktion One, or Meyer Sound, you can rent the system, listen to it for a whil...

selection and I am also corresponding with a gentleman that may help me with

[quote user="Macman"]Just realised that I had dual highpass filters on the TH, which more or less cut off frequencies below 50Hz entirely. A lot better now, still much to be made of course.[/quote]
This is very normal. People get the “building...

[quote user="noviygera"]Kris,thanks. Here's what I have:>>There is a
caveat: The combined input impedance of the power amps must be at least
10 times the output impedance of the preamp. Otherwise the load will
kill the sound of your playback...

Not that physics is my strong suit, but casually watching a physics youtube video this thought crossed my mind.

[quote user="noviygera"]And one last thing for now I'd like to ask you. Would you know of a builder in the USA that can design the horn based on my requirements so that I do not attempt to be a horn designer? I can get the design built locally.[/...

[quote user="noviygera"]
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...

[quote user="noviygera"]I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.
15" driver....

|
[quote
user="noviygera"] One question to your response. You mentioned the resonance of 80Hz
is too low for this horn and to raise it to 110. What benefits does this
usually bring, this equalization of resonance to horn cutoff? [/quote]
It is ha...

[quote user="noviygera"]Romy,why do you feel the
SS amps will not provide as good bass as tube amp? Since there is such a big
selection of SS amps, also hybrid one, is it a general rule, regardless of amp
power and type? Is it the type of distorti...

[quote user="noviygera"] What does this mean?
Let's say the OT is 5K:8 where is this loading coefficient coming from? And how
can it be adjusted? If the R(e) of a driver is let's say 12ohm, does this mean
the secondary of the OT must be 12ohms for...

Noviygera, I would say nearfield is what is before let say 10feet, but it would be all depends
of the size of the whole room, the reverberation time in the room, type of the
driver used and many other criteria. I do not know how about the distinct

Noviygera, yes to a degree a short midbass horns is not really
a horn but some sort of waveguide or
bounce-horn. A horn described, if to drop all crap out, by volume of LF equalization
(boost) the horn makes. A larger trout to mouth ratio the larg...

[quote
user="noviygera"]…. are you willing to duplicate your existing system
in a new home? Those midbass horns?[/quote]
