Bill, I am happy that you've improved your bass. As Romy mentioned in an earlier post about Bruckner, RTA is just one tool, and we have to listen and hear results with Music we know and love. When you told of the disappearing S2s, I was going to ment...

Romy, I'll limit my answer to only speaker-related problems. 1) Still too bright sound. Not hard or edgy, just too much top end. My local guy suggested trying a single resistor in series, rather than an L-pad, to tone down the tweet...

Dominic,
I have no idea. I never used them and hardly used anything similar. Generally there is no abstract intellectual value in the targeting any specific crossover point. People out there suggest “do not cross here” or “do not cross there” but it...

The units that i put in my pictures JBL AND ALTEC A7 both designs have a resonance just like all wood that you would rap your nuckels on even 2 inch thick plywood will resonate at a given frequency, that goes for glass, cement, metal, they all do...

[quote user="Romy the Cat"]The first thing first I think that your fear that your “midrange might have ideal frequency response” is not a motivation to change anything. Are you concern about frequency response or about the well-identified subjective ...

[quote user="jessie.dazzle"]Assuming situation 2 is possible, receiving mid-bass primarily as reflected sound, one would have to take into account the reflected path of that sound, and how it describes the mid-bass part of the image, relative to the ...

[quote user="twogoodears"]I'm following with interest the thread and must say that I'm baffled: Goto's "instructions" are - SIMPLY said - a mix between non-existent and wrong... I love what Goto's did in my system... BUT I think I did more with "...

The quality of microphones is irrelevant and if you use not 1/3 octave sweep but Noise Generators then you need to run time average on your RTA. Time average analyzers is fine but it need some additional experience to interpret the results. I do...

Since my new room is set and the playback is installed and configures I name an interesting observation:

Continue to think in this direction I come to very promising hy...

Hi. I got different oppinion bout the XO.For sure it has influence on the lobing. Definately, depending on which filter type u use, it will create different on- and off axis response.E.g. i like cutting the supertweeter at 8k with butterworth even or...
|
[quote user="morricab"] I guess I view absolute tone a bit differently than what you describe. I think that each real instrument or person (as in singer) has its own "absolute" tone….[/quote]
Actually when I was taking about “absolute tone” I ...
|
[quote user="twogoodears"] I agree with Mingsu questions about "what" physical area must be aligned, as every inch +/- gives sometimes different results... [/quote] Come on Stefano, you do not align the “physical area”. You guys are so preocupated wi...

In the past month I have been playing around with a sub-woofer. This is my first experience with a sub. Prior to this, I held a bias that subs generally cause more problems than they solve. I am using a sub now because the main horn...

Vitavox S2 does OK up to 12.5K ("strong, clean and in character") on it’s center but I never use this driver pointed directly to me but rather at good 20 degree off. (I hardly can tolerate any compression driver point directly to me). At my angle the...

You might check out the following website for a relatively easy to use and free RTA program for your computer. The site also has an active forum that can help get you up to speed with respect to getting the software working, mic sorted, and your init...

Thanks for the wise, simple instructions, Roman, also useful to others, I believe... that's what I actually do since I - 'twas ONLY 15 months ago... - became conscious of the limits of my tuning-by-ear and got my IVIE IE-30 with Class A measurement m...

The EdgarHorn Titan is a very well made speaker, but I have identified in it a limitation in the midrange where the frequency response may not be ideal. This will become clear after I have analyzed the speakers with RTA.
Thinking ahead, I want to...
|
It is very easy to figure out acoustically. Feed the drivers and their crossover with a reference tone of fixed amplitude and fixed frequency, roughly in the middle of crossover point. Disconnect one of the drivers and measure the acoustic pressure e...

Last couple days I was playing with my new tape looped Placette, riming Pacific from Tape Rec output. How little a Moron need to be happy!!! Even I still have some technical issuers that I need to resolve using Pacific in and out of the tape loop but...
|
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 with other drivers, ...
|
Thanks for your advice Romy and Stefano.I have used RTA with condenser mic in my past systems but I admit I am no professional at it. But I am not clueless with it either.. In my previous setup when I was playing with open baffle designed speakers, ...
|
[quote user="drdna"] Now I have had the EdgarHorns in my system for a number of weeks and have been moving them around the room and moving things in the room around to make them sound their best. [/quote]
If you are not familiar with horns then it u...

[quote user="tuyen"]When i change the cutoff of the 505tt to 200hz and 250hz, I experience that same 'hole' you mention about. Hence why I was questioning if it is the 160hz le'clech horn causing this and if using the goto s150 horn with it's di...
|
[quote user="skushino"] I think you are saying the effects of my room may be dominating any problems with the Edgarhorn bass, or at least I can't know since I don't have any objective data. Is this correct?
Maybe you're right. But here is wh...

[quote user="Romy the Cat"]Get RTA and set the band-pass of acoustic pressure form the channel identical. [/quote]Yes, I need to get one! Although Bruce and my tech guy both advise that the RTA may cause more problems than it solves, ...

Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...

[quote user="Romy the Cat"] There were some educational for myself observations made, in some way saying something about this specific DHT, in some way saying something about Melquiades’ single stage version and the Melquiades’ full-range two-stages ...

[quote user="Ronnie"]I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA h...

[quote user="Romy the Cat"][/quote]Ok, here are some thoughts that I have after the last night experiments. The tests were made with Sunfire subwoofer, wiath is bad sounding machine but excellent LF test source. The Sunfire slope wary from 3rd order...

Dan, are you using the Behringer DEQ2496 for your RTA? If so, you could
be experiencing the same problem I had. Once in a while its frequency
range goes doolally and shows rubbish - but not quite enough rubbish to
make it obvious. (I think it read...
