Hello Macman,Nice horns, I like that you finished everything properly! I am getting tired of seeing piles of horns.I think the ringing you are getting from your midbass horn is that the throat reactance is not balanced. How did you calculate the ba...

Since my new tweeter will be arriving in a month or so I am slowing completing the ideas of finalizing the frame of my Macondo. Whoever dealt with 4-ways horn-lodes know that framing of this thing is quite tough. It should be functional and none-abus...

[quote user="Romy the Cat"] Make an experiment, and I will simplify the case quite assertively. Take a typical compression driver, cross it at 800Hz, second order and load it into a proper contemporary horn (Tratrix or JMLC) of 300Hz. Listen that hor...

[quote user="Tax"] Your post has had the desired effect and I am doing some more research into Fane Studio 8M, 16 Ohm drivers in a 4 inch throated horn tuned to 115Hz with the intention of crossing it from 70Hz to 500Hz . This may be similar to w...

[quote user="drdna"] So, my thought was that below 35 hz, there are many ways of thinking about amplification. Some might say SS amplification is helpful due to power demands of horn loaded 18" woofers. To use 6C33 might be a trade off but I do not k...

It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...

[quote user="Dresden"] I've concluded that building at least two--and perhaps three--different versions of a Mid/Upper bass horn design will be required to determine which of the three configurations perform best. [/quote]
Unfortunately it is not so...

Jessie,
Perhaps if you search something in the throat jungle you might fish some interesting results. You see, optimizing the driver to throat transition you might get some HF out of upper bass driver. But besides getting more HF there is something ...

I spend quite a few hours playing with the new channel trying to ingrate into Macondo but so far not successful.
Since the new channel and the Macondo upperbass horn have identical sensitively and identical impedance I figured that I would drive it...

[quote user="noviygera"]I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.
15" driver....

[quote user="drdna"] How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range. [/quote] Hm…....

Personal, I do not use WE555 and I do not (would not) use the WE555-type horns. Hypothetically if one would go for 4-way system with WE555-like driver in upperbass then it is valid solution, not something that I appreciate but valid. The WE555 is ve...

OK, I disconnected my MiniMe speakers and left only Macondo to care sound in the room. I was listing for the last week Macondo. There is no bass, just upperbass horn at the bottom and The Injection channel a full range. It is OK sound but truly nothi...

I have just taken out of my system a First Watt F5 clone Tim Rawson amp, It was substituted by a Telefunken PP amp with 6AQ5 tubes. Let me to explain.
My system consists of 6 way horn loaded speakers. I have a round Tactrix...

The first and the bigger thing that I like about them is that Anima is trying to use the vertical-horizontal configuration where the bell of the vertical horn serves as frame for horizontal channels. I love this idea and had a number of my own th...

Since having replaced the 16 Ohm drivers in my upper-bass horns with 8 Ohm versions of the same driver, I gained enough upper-bass output that it is now possible to run all horns from the 8 Ohm taps (I was previously running upper-bass from the 16 Oh...

[quote user="Axel"] I hope I got this right when going through this long thread with LOTS of information. Did you mention for upper-bass cross-overs Elko’s (electrolytic) only to be your preference? If I have it right, any special preference at a...

In reference to the two (or three) prototypes, the base design contains one (1) driver, a second proposal to the base design uses two (2) drivers (using almost the same exact enclosure--an increase of volume/area in the chamber containing the two [2]...

[quote user="jessie.dazzle"] 6dB extra? Relative to what? [/quote]
Relative to the reference level of my MF channels. Look at the Chenal “B” of the the amp's schematics:

[quote user="Romy the Cat"] I have to admit that since the torch of sane sounding horn-loaded loudspeakers nowadays in my hands (among the outspoken people with web presences) I feel sort of an obligation to comment about new interesting species ...

[quote user="Romy the Cat"]I do not disagree with
it but I would certainly question the practicality of it alone with
cost/benefit ratio. I think if the identically amount of effort would be spend
for other aspects then the benefits would be highe...

I do not think he does anything with his company. He is known for years helping other DIYers like himself to make theirs loudspea...

[quote user="haralanov"] Romy, the actual sound benefit of this 4-channel upper bass configuration, is rather in the type of sound presentation. The commonly used single upper bass horn (or direct radiator) sitting under the midrange horn, gives the ...

Luc,
I am not ‘lucfm’ and I hope he will reply to you but I would like to pass some of my observation that you might find useful.
In my past when I discovered Fane Studio 8M I went over a number of 5-8 inches. At that time I used AG’s Trio upperb...

[quote user="haralanov"]Are there any signs for worsened transient response of your midbass channel due to the sharp electrical filtering?[/quote]Nothing that I note. The transient response of your midbass channel is a bit tricky thing as the way how...

Hi, Tim. This is difficult question, and it is difficult in it’s abstractivnes. I really do not understand, or understand but refuse to acknowledge the validity of the word “respectable”. How valid for YOU would be a “reputation” of this driver if it...

[quote user="op.9"] I agree, there is probably very little to learn luthiers that is directly applicable. However, I've always been interested in the similarities between good speaker cones and thin lacquerd spruce. Sort of a crispy pingy sound even ...

Come on, Dominik, no one cares about the LeCleach for bass. You might consider slower opening profile: like exponential of hyperbolic. Exponential will give you a bit more horn gain at bottom and hyperbolic will give you even more gain. Hyperbolic wo...

Thanks Romy. First the amps will be finished and then the Upperbass horns. I may even get the second DSET ready to go upstairs this weekend assuming everything goes well and nothing goes wrong. Will be nice to hear what I have at the moment in ste...

That is the thing exactly, my upperbass solution has the same output amplitude as the compression drivers I am using, IMHO resistrors are the devil in xovers, they kill all sound. Now the difference between 109 db and 110 db can be overcome with c...
