Is any technical background behind the statement that 4" driver can't operate in 300-1000Hz because resonance is too low ?

Well, you need to define what does it mean “can't operate”? Anything can operate anywhere and everything will produce some kind of sound. The point is that you would like a horn operate it is max capacity and a driver to be properly loaded. Only in that condition a driver and horn do not operate faulty (like most of the horns out there do). In case you have a relatively low rate horn you want a horn resonance to be loaded by the mass of air in the horn, or to be “close” to what they call throat reactance. “Close” is a very loaded statement. To have it within a fraction or DB or within a whole DB very much impact sound but in your case you will have an octave or more away. So, can let say 30Hz driver to operate in 300Hz horn? Yes it can but there you need to play only corny piano concertos on YouTube and it will produce questionable sound. Again, there is tone of information at this site regarding the subject.

I don't know about other GOTO drivers, but I know about GOTO 146 in 50-200Hz range. It is awesome for me. I predict that may be it is better then any direct radiating paper cone driver in sealed enclosure aka compression driver. This is my truth for now, so I'm gonna build system with compression drivers only...from top to bottom.

Ok, there is nothing wrong with that. A 4” of driver exit into 50hz… hm… It will be good 10-12 feet horn. If your room and your integration methods could accommodate it them good for you. Again, I do suggest you forget for now about your midbass horn and built a normal horn tower with upper bass horn. You will learn about proper integration techniques and THEN will be able to understand a lot about the midbass horns complexity. At this point you do not know what you are asking and in my estimate to go after 40Hz integrated horn would be bit difficult for you and you do not exactly know what you do and what you hear.

That is only proves my point. You do not need to talk with me about it but rather with a psychiatr.

I'm now on side of compression drivers for the bass region. If any other bass driver (not GOTO) exist, I'll be happy to get and evaluate.

It is for sure good to have off the shelf compression drives for bass region but unfortunately the implementation is the bitch. A lot of people do not go there becomes they understand the prospective aggravations and consequences. Many people among those who do it do it ignorantly and for wrong reasons - the posting of glossy images of large horn impress only the boys internet yahoos. Go and to listen this installations and if you know what to listen then you will have your expectations cleared. BTW, the best midbass from playback in my life I heard not from compression driver but from other topology.

My personal feeling about Sound is that lower we go - more we need compression driver with horns. I can hear very good highs from many good tweeters around and for extream high frequencies horns are sound even worse. That is why I'm using RAAL like you. For mid range is more difficult to find good direct radiating driver, so horns with compression drivers are welcomed in this range. And the lower we go - the picture is worse. Direct radiating is just terrible sound, but compression drivers do not exist!

I very much disagree with it. Generally a lack of experience prone to crate maximalist and absolute statements. Again there is nothing is wrong with compression drivers for bass. I however feel that the person can make generalization if she at least implement a given topology properly at least once. To hear a sweeping statements form a person who just collect requirement is a bit funny. I hope you understand that the implementation that you depicted at the picture about could not be taken seriously?

I can imagine that you got some good result with 8" Fane and 15" Vitavox, but hardly believe that it is something close to what compression driver can do.

Possibly. Might I ask you what does it mean a compression driver. I think you are not qute understand the vocabulary you use.

Integration is important, but not as much as sound of exact driver. This is what I've experienced.

Well, Murat you read me like I am your next audio review. I am not and my writing requires actually a cognitive interaction with what I say. I said: take time and spend some time of listening and THINKING of what you heard. So, far you experienced very little. You got your first midbass horn where the horn rate canceled out all lower octave and apparently for a first time you heard a playback not overwhelmed by improperly implemented bass. This plus improper amp loading and a few other factors gave you an impression of "fast and airy bass", then some fantasies about "tone colors" come (when bad lower bass is not there). That all is completely understandable and completely expected. That when I very diplomatically told you "give to yours some time" and if you are not deaf and not fool you will discover all necessary things.

Don't you hear in your system the difference in tone clearness when going lower ? Right hand sounds always brighter that left hand. And it is easy to explain technically.

Did you see me asking your expanations?

Why not to try make it better by using compression driver on LF ? Ok, Romy, you are not ready now, but later you'll come to this. I'm sure!In some thread you told that it will be interesting for you to talk about sound of your system with GOTO user. I'll be happy to visit you if you invite me one day. May be I'm wrong, thinking that 8" Fane and 15" Vitavox can't do anything close to what GOTO 146 is doing.

I do not think I am trying to convince you anything besides advising you do not insist to educate me. Honesty this attitude will not bring you traction or attention. Are you trying to advise me to get rid my upperbass and midbass solution sand start experimenting with GOTO 146? Sorry, if you are absolutely clueless what you are proposing.

Ok, Romy...I'm trying to be very polite and respectfull to break through your arrogance, but I give up I'll not spill infamous Soundex’s empty enthusiasm to your site

Well, at this point of my life I take your accusation of my ignorance with a good smile.

I'll think about upper bass horn and how to integrate mid-bass horn around my chair and keep it time-aligned.

Hm, it took for you 30 seconds to be convinced regarding the time-alignment. I wish you good luck but I have my heavy doubts that at this point you will come up with anything noble. Again, take your time, do more own experiment and less audio-forum posting - you migh end up with something good accidently.
