OK, I split the thread: “Best of the HE2006!!!” there extracting the Cogent’s related posts into a separate thread….
[quote user="Paul S"] The big RCA field coil is the best thing about the Cogent system. It has great "promise", based on what ...

Hi Romy,I see now you are throwing around the term "absolute tone" in a relative manner again :) . Why would you want to neutralize absolute tone and with a metal tweeter no less!! You are talking about a tweeter "absolute tone" offsetting a po...

Romy, it sounds like, as usual, you have covered a lot of ground already before you put out your first questions about ribbons.FWIW, I presently use Arum Cantus G2Si ribbons, phasing them in at 10k Hz to supplement the Lowther DX4's dreaded...

[quote user="hagtech"]On another note, I've been following the Fitzmaurice articles in audioXpress for years. It seems he has only one criteria for a speaker. SPL. Some of the stuff he does is really scary. But then, I've neve...

A lot of people ask me about those drivers and I’ll try to compile my vision about them. I did try most of the possible tweeters: dome tweeters with cloth cones, varies type of hard metal domes, compression drivers with aluminum, titanium, phenolic a...

Looks like Wilson hit the ground running about 20 Dec. 2016, with a flurry of quickie "reviews". Here's a link to the Absolute Sound roll-out/"review":http://www.theabsolutesound.com/articles/first-listen-to-the-new-wilson-audio-modular-monitor-wamm...

Sorry, Bernard, you are probably correct about the spelling, but it's too late for me to edit the post. I always figure anything good one hears at a show means it is possible to get good sound from the gear in question, while bad sound might say com...

OK, Petar, I was finally able to take some time yesterday to focus and meditate on this. I remembered a host of "old" drivers from my past (not old at the time...) that, if memory serves, sounded rather muffled and slow, with humped response, as "he...

Fist off, hello to everyone. This is my first post here.I have a DJ/listening system in my basement. Mostly, self made. Some pictures:http://picasaweb.google.com/noviygera/BasementSystem#Just recently i installed new Funktion-One RES1.5HS horns. Pict...

Ah yes, sorry - that wasn't remotely clear. The drivers I have played with briefly are S2 and field coil RCAs, both have the same 1.5" throat. I was referring to my initial impressions of the sound on Martin Seddon's 160Hz horn (T=0.8 JMLC). Previous...

Again, I do not agree with all notion of Rubber sound that Haralanov seeded. I can not speak what was in the situation that “be” described and 400Hz crossover. I do have the 8” version of 25W driver (I think it is 21W) and my feeling that it sou...

hmm..well.. duelunds.. they ARE mortgage lifters! i think i'd be more likely to hunt down old vitamin q's for a few months while settling though... i did try solens-- and while they were a revelation by comparison to absurdly overrated voltage...
|
|
Romy, at some point you did mention lowering current and shortly thereafter, if not in the same post, you added something to the effect of raising voltage. You even mentioned values you have tried, and I printed it out. But since I am usu...

Yoshi, I knew Frank Reps WAY back, in LA. I have talked with him in the last few years and know a little about his drivers, but I have never heard them.It was my understanding that Frank used the AER cones, or he OEMs them from AER?In...

[quote user="morricab"] Used Wilson X1 Grand SLAMM. Not the best speaker but dynamic like a horn and less colored than most horns. Use with good tube amps and it makes a superb sound (with 95db/watt sensitivity and an easy load 30 watts is probably s...

MSA, I'll grant that greed is the force behind much of modern "technology", and I agree that good drivers are few and far between these days. However, I am not as sure as you are that an old Hartley driver could properly charge Romy's house with mus...

Mark, what is it exactly that you have heard from the S2s that attracted you in the first place? This is important, I think, because this is what you have as a starting point, to work from and to use as a reference point as you develop the soun...

[quote user="morricab"]Hi Romy,I have found that the Apogee loudspeakers ribbon drivers can quite successfully reproduce correct tone. The reason why is this: They have very little coloration from the driver materials themselves (no nasty...
|
|
Bill, it sounds like you have made a significant investment (time and resources) into (re)producing reverberation with your entire system, also setting time alignments of various drivers, across the board, and I assume you would not have gotten this ...
|
|
Amir, I have shared that I quite liked the (original) Audiopax amps I have heard. Whatever they claim, they do sound right to me. Although I have never played much with a de Lima amp I have played quite a bit with most of my own phono stages, pre-amp...

Haralanov, Yes and no. Of cause no one would deny the benefits of ULF reproduction but the key questions would be: 1) what kind of reproduction? 2) how to talk about it? There is no language to convey the ULF message. The 20K repose is meaningless an...

Hi,[quote user="Romy the Cat"]T, would you elaborate on it if you feel that it has any merit?[/quote]Really, I do not know. From my limited experience I have found that multiway active systems are very much a tuning excercise par excellance. Given th...

Herman, horn dimensions does not described by size of driver but only size of throat. It will be absolutely nothing changed in the horn dimensions if you go from between 10" and 12" driver. Sure you would need a bit larger back side of the horn to ac...

I would like the people who read this site and those others whohave genuine interest in Vitavox understand that that subject of old Vitavox production is a bit tricky and I would not be surprised if the truth never be known. There is not such a thing...
|

MS2, I certainly agree that the specific tweaks/changes you mention would/do change the sound from a given driver, along with myriad other "elements". Now, the questions and supposed answers included/implicit in your post make me think. While it is...

[quote user="amdismal"]The crossovers were fourth order, which is what I use on my horns. Second order, I have found, can give a better blending, but reduced the delicacy and transparency in my system. But it's very complicated, and further exacerb...

Since I have struggled with my own +/- insurmountable problems with Lowthers, OB, BR, etc., ad nauseum, I can certainly relate generically to what you have just said about horn drivers in this injection thread.Yet this may be the only time I have hea...

Mr. Witmer seems like a very thoughtful and well-spoken person who is taken with the aesthetics/approach of various Japanese sound Senseis, most of whom are in turn rooted in "historical" American and/or English audio sensibilities. I'm afraid ...

[quote user="Paul S"]Romy, when you mention "dynamic sinking" of ribbons are you speaking of sub-8k Hz use of powerful ribbons like the Water Drop compared to 109 dB efficient compression drivers, or do you notice this dynamic sinking no matter ...

[quote user="msaudio"]49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low ...
