It's might be another project...

f you could go uploaded couple video clips when I I I was reminiscing compose a time when I was building my playback and I have some nostalgia about it. I really like the time when I was navigated a project from point a to point b reflecting in my actions some of my personal views and visions. The fact that it was materialized in some kind of creative machinery was very gratifying to me. 

Nowadays I am not exactly bored with my life brought to my huge surprise some accidental events couple days ago inspire me to contemplate another project. I will record video about it when I have time. I did a number of my audio projects in the past, where some of them were very successful and some of them were clearly failures. I have a good feeling about it. Irony that I absolutely do not need it but something tempt me to do with it.

I am still thinking about it..
Last night I have a long listening session of my New corner loaded speakers, I don't have a name for them yet. I kind of feel sense of amazement what they do with the lower register. Some of very very complex thingd they do amazingly interesting.  I was listening to my favorite recording of La Mer by Berlin philharmonic and was really pleased of not impressiveness of this lower and upper base. It is very different from my main system does. Macondo in its current configuration has unquestionably much more Superior bass. But when I am talking about performance of specific register I always think in terms how I would like to change it in order the result comply with my belief how I would like it to be.  With all quality of the base that I am getting from my Macondo I always feel that I would like to have slightly softer very bottom range. I understand that it is not exactly possible because I have my lowest channel in Macondo driven by a solid state amplifier. I am a strong believer that any solid state amplification topologically cannot produce proper base. I certainly have its flowing over a tube crossover which specifically optimized to increase second harmonic, it helps a lot but it is still not a single ended bass. However, when I listening my corner horns which even remotely do not go as deep as my main system I do not have this feeling that I want to have slightly softer bottom end. Do not forget that I am driving my corner horns not even solid States amplifier, but exceptionally horrible amplifier, from a single integrated chip of total cost probably a few dollars. I think what happening because I have a dipole corner horn there are some very intricate phase randomization that overall make bass very interesting. I am still thinking about it...

Jensen Technical Bulletin 3

Having lived with back loaded horns for a few years (a few decades ago I was infected with Yellow SingleDriveritis), this topology brings up a lot of memories.

Rommy, if my eyes don't deceive me, I am detecting a blurry 15’’ firing behind the grill cloth located near the bottom of the front baffle. By any chance, is this horn related to: Jensen Technical Bulletin 3 ( https://aafradio.org/audio/Jensen_TB-3.html )?

BR,

I might be full of it

Antonis, the type of the hormone is your link it is exactly that type of the horn that I do not like. It has multiple bends, it means it has a fixed resonance chamber inside itself. My corner horns has none of it, it is just a mouse a radiating into corner. 


Saying all of it, I am sound like some kind of corner horn expert, and I am not. I heard plenty of corner horns that I very much do not like and I had only two horns that I do like. I did not have any personal investigation why I like it. There are many variables why those two corner horns sounded okay and my presumption that it is a topology is just my guess. It does not based upon any of my experience to actually to make corner horn to sound right. So, if I were you I would not use me for any kind of point of reference as corner horn is an apology about which I have near no personal experience to deal with.

"Random Venting"
Romy, I am reminded of large olden days enclosures that were "randomly vented", in that the venting was meant to diffuse backwave reinforcement/cancellation rather than trying to use the backwave to augment the front wave. It is very difficult these days to search for Tesla (Tesla a.s., CZ) speakers, since all search engines are trained to show Tesla cars. Anyway, the large Tesla ARO woofers were used in large and heavy double-walled enclosures with "diffusion vents". I experimented with this concept by drilling multiple random sized holes in the backs of empty boxes, and at times I used a rock wool "curtain" behind the driver. These enclosues do not "help" the driver in any way, really, but they come close to IB in terms of allowing one to hear what the driver itself has to offer. I did not try any of these enclosures "corner loaded", and - of course - the room figures largely in that case. Not to say it wouldn't "work", rather any particular "solution" might be fairly room specific.

I think the "big problem" for any large woofer candidate is equalizing output in the passband, and most fancy "solutions" have the real world aim of getting LF from a "reasonably sized" enclosure. I think, regardless, there is no Free Lunch with LF, although I certainly agree there is a lot of room for the improvement of Musical Bass. It always gets my attention when someone goes after Musical Bass.
