All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

Hi Romy,
Sunfire? No! Who would add a Sunfire to this system? The black box in the pictures a power amplifier for the midbass horn.
A second MF could be interesting. I will see if we can do some test set up of this. Per has the space for it...

You are right: The Grande Utopia is one of the names that very much in the mainstream and have very much pre-inclined exposure in industry. That all will assur...

People, keep asking me about the sound of Melquíades and I feel strange as I really can’t not explain how it sounds. It does not make any sense as I initiated this thread with the objective to explain or at least to inform about the Melquíades’ sound...

[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]

Just how important are subharmonics and undertones in audio, and how they affect tone? I played around for a while with the Townshend supertweeters, this is a ribbon tweeter that you can barely listen to: you plug it in and put it next to your...

[quote user="Romy the Cat"] Considering the problem you described, it was pretty much, where I expected it to be. However your explanations are kind of sound strange to me. If your tweeter were out of phase with the rest of the drivers then it would ...

The EV 350 cones are still available form many sources, they are $25 per cone. There are some other phenolic domes for 1” driver, or smaller. I do not know anyone who does 3”-4” phenolic domes that would make them suitable for MF drivers.
As far as ...

I did not shoot for the Collectors' Holy Grail to start, but I looked for and bought a +/- "generic" version. The 3.5" I bought are unusual only with respect to their atypical (smaller than the usual 4") cone. They are 88.9 mm, as I recall. Otherwi...

Mats,
I have my opinion on the subject of the objective truth of knowledge but it has nothing to do with the subject of HF sufficiency. What I was talking was way more primitive and banal. The acoustic-like concentration and dissipation of HF within...

The discussion of topology is interesting, but what in fact are we addressing? The factors that have been mentioned are: 1) Sound, which in this case seems to be dependent on "either you get it" - or don't2) Topology, which in my experience has so ma...

[quote user="Paul S"]Do you actually prefer the S2 at crossover frequencies, or is the problem driver compatibility, or is it just too much sound at crossover? If you have the power to burn, why not scrub a dB or two off the ribbon, or ju...

el`Ol,it is quite fascinating how well you depicted (listening to WP 8!) what I heard, listening to some 5.xI.E. "some characteristic shining or radiance probably induced by the breakup of carbon-doped paper cones in combination with the anorganic-pa...

Though he seems to like running several TTs in parallel, I do not interpret Pham's page to show that he is running more than just one horn system; what I see is an evolution of a system. It looks like, in its latest iteration (under the heading "Syst...

Their are a pair of Pioneer Beryllium ribbon tweeters on ebay
with about 8 hours left (Item number: 5790340383) for US$25
The part number is PT-R14A, maybe a distant cousin to the TADs??

Eventually, I had a chance to spend last night with up and running new Milq (no tweeters was involved at this point). As I said before, the major fight was around the MF channel and I feel I did found a good configuration where the MF channel takes a...

As some you guys who flow this thread know my search for Macondo lead me to the world of ribbons. In the mid of last October some of you (I believe it was Chris) pointed out to the RAAL company. I was skeptical but decided to explore the opportunely....

Andy,
I do not know how aggressive roll-off on obsolete values as I never cared to calibrate my analyzer/microphone above 10K. Well, it was calibrated a few years back but I never trusted to it as I do not see needs for above 20K lineriarity from li...

OK, MiniMe now is up and running. It does what it does and I wonder if it can do better then what it does. The LF sections need to have ports fine-tuned but I do not particularly care about bass now. What I do care is MiniMe to have a certain quality...

Something they mustve obviously done better than others using beryllium. Judging the sound. In a positive way. The lower 3 are titanium, but all upper 3 are 4/3/2 inch BE sourced from truextend. The suspensenion however is soft and allows excursion.I...

Well, yes... I've not been to prison in over two years! Apart from keeping me off the streets at night, the results when listening to one of the 40Hz horns were, dare I say, encouraging, though I do hesitate to say so, as the "evaluation" was carried...

Romy,Your Macondo system is something that has been a "role model" for what I'd like my playback system to be in the coming years. And much of what I've learned about horn playback systems I've learned from reading your writing and other posts on thi...

OK Romy, I agree this should stay here, especially that I will probably have more observations to come as from the late January.
I didn't explain the context of S3 use in my future system. I'm awaiting for a delivery of Beyma TPL-150 which will be ...

[quote user="vinylithicum"]Here are some of my observations regarding the Wolf von Langa RCA 1428 replica. I long time wondered where mr. von Langa gets his phase correction elements and the diaphragm for his RCA 1428 replica. It's obvious that a nic...

[quote user="Romy the Cat"]So, I guess you do not measure flux if are getting. You might measure sensitivity and we might presume what when perm magnets has the same sensitivity as electromagnets then the drivers have the same magnetic flux density. ...

I think guessing what the hell they did with tweeters would make since if whatever they did sound right. Since Living Voice’s is not the company that has a lot of exposure in US I do not think I will ever hear those speakers. Even if they have US rep...

Steve, I would encourage you to “get” the following.
