I think this post need to have an epigrapher:
“We knew what we wanted to hear, and so we developped, and developped, and developped... In hundreds of small and bigger steps. Over thirty years. Till we were "there" where we always wanted ...

I'm sorry, I thought I mentioned that I was responding to the earlier post about HF, up the thread. I guess I misunderstood from other reading that you much preferred your crossovers at line level, while I was proposing it a...

On Friday a guy that I invited long time ago shut me email informing that he should be in Boston this weekend. I have just one freshly cooked 6-ways Super Milq and just right functional Macondo channel. I did not wan to brash him off and I connec...

So I am aasuming that you are referring the very low level capability of your driver or amps? The subtle nuances?What other drivers did you find did well beside the Vitavox. I always felt that most comperssion drivers are a little tightand need to...

I am interested to find out more information about how DEQX will help solve my issues with getting better soundstage, imaging and depth with the Edgarhorn Titans. I read some reviews from the DEQX website and sent them an email but still waiting...

Well, first of all the phrase “rated flat to 300HZ” is kind of ambiguous. There is no such a thing as “rating” - they write whatever they wanted. Second: yes, you understand me correctly, I would prefer to have lot of room at bottom and I feel that i...

[quote user="Romy the Cat"]The line-level crossovers work against fixed impedance and therefore the crossover point and the time alignment does not fluctuate along with reactance of the drivers.[/quote]Okay, maybe this is a dumb question, but why wou...

[quote user="noviygera"] I want to listen to both 12db/octave and 6db/octave passive versions and see which one sounds better. And keep the one that sounds better. [/quote]Herman,
It depends what you would like to listen. If you would like to ...

As I have finished remodeling my new Opera room:

[quote user="Paul S"]Anthony, this is a very smart installation, IMO, because you have not "over-committed" to areas where you have work left to do, and areas you have committed to are flexible enough to allow adjustments you will likely need to do. ...

Of course, any speaker is a compromise rather than a "solution" for the complex problems of "phase", which can hardly be "solved" by fixing driver diaphragms in the same verticle plane, at least relative to the listener. Not to say that this is not w...

Kerry, thank you for sharing your paper diaphragm idea. Very interesting. As I remember it, the Cogent diaphragm I saw (and listened to) at Steve and Rich's place was a flat disc of something like fiberglass, and it looked relatively heavy for the ap...

Maybe it has some interest but:- Backloaded bass horns- 2" midrange driver with Beryllium membrane- 1" tweeter with Beryllium membrane- 0.5" super-tweeter "a la beryllium"sounds quite worrying to me.Nothing is said about the upperbass channel dr...
|
|
Anthony, congrats on your amazing progress! I know how hard it is to carve out time for this stuff! I see you are looking for gain from your pre-amp, which makes me wonder if you have been using the passive Placette, as opposed to the active unit, wh...

Is there any abstract value to going for a preamp with a stronger output if you're using a passive xo at line level?I'd prefer to answer this question myself but i really don't have the budget to be swapping amps.How does a PLLXO interact with a non-...

[quote user="unicon"]if you could understand the basics about how audio waves especially bass range acts in closed space you wouldnt even bring the name Bass EQit just cures the sound pressure in a single spot(listener) and possibly can not do anythi...

Haralanov, let me know if you actually have something, otherwise I will continue with the Audaphon ribbon for the first round of the downward-pitching exercise. On the one hand, I wish I'd kept the Peerless 2" paper tweeters I had; on the other hand,...

Lost in Space? More like Spaced out.Taking Tramadol and Soma for a cervical problem. I listened to Art of the Portuguese Fado Guitar and everything was 3D.Kidding aside, I did some reading yesterday. Some online articles on the DEQX makes me want ...

I'd also start ordering the parts if Romy was able to revisit this thread. What will it take Sir,
the rally monkey? the wave? mailing you our DSP crossovers as deposits?...

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...

Romy, I appreciate that this is an old thread now and that you may not remember everything from your time developing these amplifiers, but I have a (hopefully) simple question about the upperbass crossover in the schematic above. All other channels ...

Well, I do not know what should be hurtful in it. Bruce does have an idiosyncratic clientele and the absolute majority of them are heavily Morono-inclined. I told it to Bruce but he himself is not a fool and he knows it very well without my ass...
|
|
Well, how many absolutely transparent passive crossovers are there, line level or not? For me, the question is the other way round: if a passive crossover at 1 kHz can be done with good quality, I can "get away" with a single amp for the region over ...

Looking at the second picture, the side view, it looks like
a lucid loudspeaker, time-aligned I presume. I think it is time now to
experiment with some fancier drivers…. after you change the electronics and crossovers
:-)….
Let me to expre...

[quote user="Gregm"]Coming back to the "multi-driver" spkrs -- especially unfamiliar ones. It has taken me a long time to "optimise" the positioning of a pair of 4-way spkrs (9 drive-units, of which two in the back, in phase)

Had problems 2 and 3 here with my British crossovers
Both speakers have the 78 hz. Dip after a 50 hz. Peak. they are probably room resonances. Try moving the speakers and/ or the mike and remeasure.
Also you ha...

[quote user="Kerry Brown"] For years, I used to have passive line level filters and tube amps - single ended 45's and 2A3's.
To make a long story short I am much happier now. Screw tubes ! ( Don't hate me. ) [/quote]
Kerry, I do not think that som...

[quote user="drdna"]I have found the next obvious glaring problem, which is contributing to the muddy sound I described earlier. There is a mismatch between the two channels. The right channel is very slightly softer than the left with a ...

Jorge,
You're right about using identical amps. No doubt.
I have not used Dr. Edgar's passive network but I have tried conventional passive networks on Edgarhorns. They worked alright.
And I have...
