[quote user="twogoodears"] BTW: while in Berlin, last May, Frank Schroeder performed an interesting, provoking "blind-test" using '50s and '60 Telefunken's midrange loudspeakers (22 cm diam.), comparing FC vs. PM:almost everyone in the listening ...

At CES there were Viagra-junkie sized power cords everywhere for $5000. Around our room were $10k and $20k speakers that sounded like a wet jukebox. It was the land of delusion.Value per topology is one way to measure but let's instead start with a p...

Cat:First off, the Silbatone Aporia is $30k/pr not 100k. You could do 6 speaker surround with Aporia for well under $100k. Hope you feel better now."So what," I say. $30k is already too much for my pocket. I am on a fellowship this year and cheapskat...

[quote user="Joe Roberts"]I have had round Edgarhorns and Lowthers so I understand what narrowing radiation as a function of frequency is about. My thought sniff tells me Romy's rig is good enough that even if there is some component of self-delusion...

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...

When you say, your horns are 11feet apart, does this mean from acoustic centre line, or the outside perimeter of the upper bass horn. If it is from the outside perimeter of the upper bass horn you are having a similar setup with mine. When they are a...

Mats,
Actually I do not exactly understand what you are trying to accomplish. The Altec midrange after 4uF will roll at 3.5kHz-5.0kHz, depending of the type of coil you use. If you cut the MF channel so high then I would ask why you do so and why yo...

Hi,[quote user="cv"]Fairly sure it was a typo, but the bigger the airgap, the *lower* the inductance, all else being equal.We need a large airgrap for a 6C33 due to the high current. The advantage is that the airgap linearises the BH characteristic o...

[quote user="haralanov"]Actually I see the biggest benefit (besides the huge sound body) in the fact that such a configuration allows very precise adjustment of the way how the harmonics of each UB channels touch the midrange, by simply dealing with...

I am not laughing. Just the other day I had the upper bass a little extra prominent, and midrange was gently tapering off into the highs. Some would say it was rolled off and flat, but when I played two Mahler 1's and the 9th, I enjoyed him like ne...

No, i really did mean a 4592nd midrange - it is a OEM version that I think I bought from assistance audio. There are various reasons I'm crossing over at 3k (more like 2500hz now) - first, the horns are 250hz and therefore too deep for high treble wi...

of MTM arrangement of two TAD 1201 in <100 Hz Horn ? I assume they would both work in the same frequency range . Also JBL LE8 is only 89 db driver and it doesn't look like it can take any power . Difference in efficiency within the channels would ...

Hi Romy,It seems that the idea of tone is not only lost to most speaker designers but to most electronics engineers as well. When you hear the excrement most designers call an amplifier you would swear that they have never not even once heard a real ...

Dear Romy,
Thank you for the commentary and the advice with regards to the need to have a COGNITIVE ORDER OF SUCCESSION and to test with another speaker in situ first.
Given the varying degrees of how different individuals process COGNITI...

Hello guys! I got an old Coral X-VIII from Japan. Its an Onken enclosure with a 400 Hz horn. And I want to give it a second life. The enclosure looks already like new. And the question is about the crossover. What would be the theoretical best points...

Putting together a speaker system that ticks all your boxes is a lot like doing anything else well: it is fine to experiment in order to find your range and learn your options but once you choose a path you must stick to it. Chopping and changing i...

Another K&K user contacted me recently, and he subsequently sent me new MOSFETS to swap with those I had in my unit. Original MOSFETs were Supertex DN2540. New MOSFETs are IXSYS 1N100D.The only reason I swapped these was out of curiosity. The ...

I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression drivers I tried. That is wha...

This is left channel. Right channel is mirror image.I am using 6db active crossovers all around.The subs are pair of 18" Aurasound 1808 per side. The current midbass is the white color horn you see. It is Funktion One DS15. The issue with this one i...

Mani at al. I have a paid of zu druids. Running them with 15W amp (d-class) and it is not enough for high level, although it does better than you expect. The soundstage sensitivity measurement was 97dB, but their test did not load the driver correctl...

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.

I would like to share my 5-way horn project.
The idea was to have full range system, so the first horn built was Tapped Horn.
I got design from Volvotreter.de and was really impressed with performance of this monster.
