Not at all looking for suggestions on what to do but to share findings about the optimal use of the multicell midrange horns. For example, I see that Romy has played around with this horn and I am sure listened to it by itself. So what were the findi...

"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...

I don't want to pull the thread way off but the thought occurred to me while reading here that audio bass never fools me into thinking it is real. Even my middling system once in a while can fool me in the midrange and treble for a few seconds or so....

[quote user="Kerry Brown"]My system is 4-way using 2x DEQX HDP-4 processors; 2xNuForce mono amps on the midrange horns and 6 x channels of a 7-channel NuForce HT amp that uses the same circuit. The DEQX processors function as crossovers, speaker 'cor...

Besides hornresp modeling, is there things to think about when starting design and build of midbass channel from scratch? The range I need is 60 to 300 hz. It will be used with 6db/octave crossover. It will be located under my midrange horn -- the mo...

Why dont you use your midrange horn with the JBL from 600hz to 4800hz? I think it would have a fairly flat and good response and tt wont be beaming. It works with the tractrix 1000, I have done it before. I then tried my Radian 475be with JMLC1400 fr...

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...

I am hesitant to reply in this thread since I do not play piano but your struggles with mid/treble balance and lid position triggered a memory of an article I read years ago. I think it concerned Arthur Noxon but it wasn't a tube trap. I believe he a...

Romy,
[quote user="Romy the Cat"] Remind you that horn
not only does that but it performs acoustic transformation gradually. [/quote]
Yes, I do
agree with you about that. From both theoretical and practical point of view it
is 100% true. But...

[quote user="floobydust"]As Romy pointed out, having high gain is not the same as power. If you're only barely cracking the volume control on your amplifier or preamplifier then it should be obvious that you have more gain than you need. If you're p...

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...

are happy with the mid/upperbass and midrange. [/quote]
That was very loaded statement

[quote user="dazzdax"]Sakuma San is some sort of cult figure among the tube-o-philes. I wonder why he is implementing so many transformers in his amplifiers. Using transformers can be a good thing but in my experience too many transformers give a som...

I listened to these on my OPPO SE which has an info display that verifies the recording sample rate, and also...

[quote user="morricab"]It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. Personally, ...

Well, I loved, loved it loved it… but today I decided to experiment with integration the new horn into the system and learned that it would be far much complicated and take more efforts. Below are 3 sweeps form listening position, Firs is the new hor...

Didn't you first become aware of MF "problems" when you got everything else working better via the PP2000, and the MF wound up dropping back to weak sister status with respect to system-wide PP2000 benefits?But how often is a "serious" (and ever-evol...

Paul, Points well taken. The F120A is listed as a FR driver. In my humble view, it does quite well for it's size, albeit the last two octaves will not be in full force (okay, the last octave is mostly MIA). It's lower sensitivity does not ...
