ACTIVE CROSSOVERS
1) Loudspeaker drive units of different sensitivities may be used in one system without the need for lossy resistive networks ( and L-Pads ) or transformers
( DEQX lets me use 98 ...

On Thursday ,trade day a variety of music was being played and you could just wander into the room, it was always busy, for the rest of the show he same handful of songs were played, the demonstration on ly lasted twenty minutes, such was the popular...

Well, I have a theory that the rough surface may be helping to attenuate multiple back-forth axial reflections, but from what you say, it may be that it results in - what's the proper term? - irregular as opposed to laminar flow at the surf...

[quote user="drdna"]It is important to remember that the Subjective musical result is the goal, but this does not mean to disregard all objective data. When one sees something as ridiculous as the Brazilian horn, you kind of have to assume obje...

Romy,
Even using " digital dreck " ( and not knowing what " interesting imaging " might be ) my horns image very very well. Only in the sweet spot, but that's fine with me.
For instance, on good recordings I am easily able to hear/see if/when...

[quote user="Kerry Brown"]Why preface my comments?[/quote] Because it helps to put your comment in objective perspective. It is internet and people express opinions without any tangible common denominators of reference points. I might make a comment ...

[quote user="Kerry Brown"]I don't understand when you say active crossovers don't attenuate. Mine does. Very well too, I can trim channels to match each other perfectly. And DEQX volume control is 'analog' = step ladder resistors. [/quote] I am not...

[quote user="Kerry Brown"]I used the term 'sophisticated' literally: so - phis - ti - cat - ed Adjective: 1. ( of a machine, system, or technique ) Developed to a high degree of complexity. As do you, I prefer multi-way horns so most DEQX based syste...

Hi Jorge,Thanks for your quick response. I believe I came off a bit brash and apologize as that was not my intention. I edited my comments above a bit for clarity; I found the DCX quite useful at low frequencies. The DCX is not a perfect unit but I ...

Jeffery, I think Romy brought up some good points about moving the crossover up. I've always wanted to push it down, to use the hf driver more as a full range unit, which is probably the wrong to go. Steve proved this to me when we ...

Well a DEQX will cost you less than a set of good caps! you can buy one and play around with it for a couple of months and see for yourself, you will have fun anyway and thats what tis all about! You will need and extra preamp and 3 different amps...

Stephano Two good ears has put a post on his site about his new 4 way passive xover.I think this is a better direction than the digital xo. The designer, Thomas, designed also the preamp and I guess he has taken into consideration the input and ...

I read your comments re: the PT-R9.
I have a pair which also measure about 9 dB below my Supravox 200 EXC drivers in sensitivity using the Earthworks measuring mike on the DEQX unit. They do sound very nice, however.
Also, I find this site to ...

Romy,
Why preface my comments ? I've had the same system for 10 years basically. I do use digital crossovers but the 'Class D' NuForce amps are not digital at all. And the NuForce amps don't sound like stereotypical Class D amps, they are very quie...

[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...

Greetings,
I may be able to answer some questions regarding crossovers, multi-amping, etc. - without getting bogged down, hopefully, in metaphysical issues.
First off, I live in San Francisco, if he's inclined 'drdna' and other locals are wel...

Romy,
Funny stuff... especially the the AN piece. Equally surprised octopodes ? Brilliant !
As for the Bruce Edgar post ? Not as funny. And it's off base.
The Titan II system has a straight axis upper bass horn instead of a folded upper bas...

Jorge,
I know what you mean about horns, Living Presence. I love what my horns do. Palpability. Solidity. In an invisible sort of way.

Jorge,
You're quite welcome to visit any time you are in the SF Bay Area.
