A DSP is a great tool for modelling crossovers. It lets us experiment with a lot of things with no additional costs. There is a sonic hit, but far lower than "guessing" at crossovers.What seems to get the most traction here is using inherently well b...

Yes, a cheap inductive l-pad between OPT and S2 in midrange channel. Interestingly, the frequency response of the first order Lazy Ribbon is remarkably similar to a response you posted somewhere on this site of the Water Drop with third order filter...

Sorry for reviving this thread without a good reason, but there is something I wanted to add to my comments about amplification. Recently I heard this system http://www.hornfabrik-eder.de/ which was driven by an old Telefunken studio amp. O...

I use regular Lowther DX4 (ENABLED) . I don't think the 250-400 is stellar and I'm still waiting for the extension to try small throat for lower midrange (2,75") (B&C 8P21E driver) for 200-1000Hz . Here is Martin's opinion on the ...

[quote user="Merlin"]Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405.[/quote]I do not know which driver the Living Voce us...

[quote user="drdna"]It is important to remember that the Subjective musical result is the goal, but this does not mean to disregard all objective data. When one sees something as ridiculous as the Brazilian horn, you kind of have to assume obje...

I am new to this interesting site, and am hopeful of getting some assistance with a project. I have purchased a set of TAD 1201 mid-bass drivers to begin a 4-way active system for critical home listening. (in a dedicated room, 21' x 25' w...

Brain, C’mon, I was kidding about the “Electron Intensification Interface”! There is nothing in this phonocorrector then a correct selection of tubes, thier proper (well almost proper) use and selection of the specific topological decisions that sold...

[quote user="Jorge"]Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, ma...

"Best bass" is of course a matter of opinion based on experience and expectations. The (original) Hartsfield LF driver is certainly "designed for horn loading", like the Vitavox AK-151, whereas the AK-150 and the JBL D-130 are designed to be direct r...

Nope, sorry, it does not make any sense for me. The use of Rowland amp I guess is fine if it being use for testing of the filters. Still if you use high-pass for your midrange horn then what resistor does in your RC filter? A first order filter, rega...

Hi all
Yes, the thing with midbass/upperbass horns , as Romy states, is that those horns are usually built to be too short. You might actually be better off using the driver in a sealed box.
For example, look at the size of a typical upper midra...

[quote user="Romy the Cat"] Try to drop the Altec in 400Hz horn down to 1000 Hz -700Hz and arm your Oris with a MD driver with a good lover midrange driver (B&C of whatever you use) You will be able to go away with 4 channels… You have a lot of n...

I believe that those "allien sounds" are an enhancement of the frequencies comprised in what is called the singer's formant, which is the area of the third formant when opera singers sing vowels. That area is in the range of 3.5 to 5.5 KHz and is a s...

Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.

My COVID-19 brain fog has finally lifted. I have been using HORNRESP as the gold standard for horn design. Upon reflection I forgot that we ultimately listen to the sound produced and not the beautiful computer simulated SPL profile. So I ...

All that I will be saying are the subject of my own experience with horns and my personal observations. You shouldn’t agree and most likely you will not. That is fine with me. I have lot of reasons behind what I will be saying and opened for some cla...

In the linked there above “Barn Conversion - James' Project” I have expressed my attitude toward low frequency bass. I certainly not “against” bass horn it but have “concerns”. The “open bottom” concept that I invented for myself is always make me to...

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

Hi all
The WE 555 is IMHO an interesting driver, made for a very spesific use,
which is driving a "full-range" horn in the theatre.
As we all know, the wide range system with Jensen 18"woofers and Bostwick tweeter came later, at first the 555 an...

[quote
user="xandcg"]I was thinking ESD drivers may have a true advantage
over ALE/GOTO/Others (apparently they actually know how their drivers work) if
that allow to someone design the horn exactly the way he/she want, and later
order the driver...
