[quote user="jessie.dazzle"] I do my best to remain ignorant of the price for which I sell off the hours of my life. (Btw, I'm not a software engineer; I design cars). Yes I could pay someone to do the work, but I'd rather put the cash toward the pur...

Jessie, I can say without knowing anything about LF horns that those I have heard were indeed ineptly implemented. And I would die the Death of 1,000 Cuts before I said 1 word about my own pathetic efforts in that direction.Sorry, I though...

|
Jessie, Unfortunately your images did not make and the most important dimension: the throat size is not visible. Will you go for 12” throat? Sometime I will do pretty much what you do, ironical using the very same drivers. I have a pair of AK154, a p...

Jessie, do not forget also while you do your alignment experiments to listen the system from different distance. Get a reference whatever it is and then make a step back and a step forward. Try to discard the upperbass changes and pay attention only ...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

[quote user="jessie.dazzle"] There should be no danger in running the S3s down to 500Hz; I am currently running a pair of S2s (same diaphragm as S3) down to 450Hz, 1st order, no problem.
The system is in a room that measures around 80m² with a 3m-h...
|
|
[quote user="drdna"] What was more concerning is today some 60 Hz hum also re-emerged in the system, sounding like a vibrating cell phone going off in the back of the room. It was interesting how it was sort of localizable, but the hum is annoying. A...

Jessie-Good to hear from you. I am very motivated following your progress. Thanks for the inspiration.My room size is around 15' x 18' x 8'. At this point, I feel that a proper 60 - 70hz midbass horn is physically the largest I am realistically pr...

[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="jessie.dazzle"] In the case of a normal ranch style home (one level, no basement) out in the burbs, the attic is wasted anyway; you could put it to use, and if necessary, modify the roof, letting the drivers live up under decorative ...

Jessie, 45Hz horn with 6”-7” throat around AK151 driver is from my perspective is the best thing might be theoretically built around a cone driver. I really envy of you and if I had room I would unquestionably go for it; this is why I keep a pair of ...

[quote user="Wojtek"] I heard that some audiopholes don't like to go to classical performancess because their gear just SOUNDS BETTER [/quote]
There are many very reasonable explanations of this sentient. I do not go in there as it is what of the su...

Jessie,
Unfortunately it is in my view it is absolutely imposable to predict anything juts based upon the CAD modeling. The entire criteria that you for founding the right positioning of your instantiation are wrong, at least in my view. You use the...

[quote user="jessie.dazzle"] I don't have a problem with what Lamm has done in offering the ML3 (ignoring the price)... If I have a problem it is more related to how the product is being represented. Representations aside, depending on how it sounds,...

I would like to point out something that is going on here that I found truly remarkable.
For advanced people ho play with horns there is no second opinion that the vertical array, the Macondo/Cressaro-Gamma type of architecture, is THE ONLY one tha...

[quote user="jessie.dazzle"] Could you clarify: Would you like to vent the rear chamber or increase its volume (or both)? This weekend I will try listening with the rear covers on the Lower-Mids slightly open... [/quote]
Good question. I do no...

[quote user="jessie.dazzle"] The AK150 and 152 are not new creations dreamed up by Mike; they were made back in the day by Vitavox but nobody ever talks about them and I have never seen either. See the Unofficial Vitavox web site; AK150 = Catalog...

[quote user="msaudio"]Putting The Mid Bass horns behind your head will not work. This thread was about Mid Bass Horns Project, do you thank you will be able to use any frequency above 80 cycles with rear fired horns that are behind your head? Tha...

[quote user="jessie.dazzle"] You might try the Foam Factory; they are easy to deal with, inexpensive, have online ordering, quick turn around and can ship anywhere.They are NOT a typical audiophile-oriented acoustic room treatment supplier. Never...

[quote user="jessie.dazzle"]The Velodyne SMS 1 will allow you to do just about anything, up to 200Hz. [/quote]I was the Velodyne crossover into the game yesterday. To my surprise it not as convenient as I thought. The high pass filter is not defeatab...

Jessie, we keep meeting at the same intersection. Like I said before, I agree that direct radiators suck, for all the reasons you cited. But if what you say about horns is strictly and completely true, then does it not follow in spades at ever lower...
|
|
[quote user="jessie.dazzle"]I didn't read the entire thread, but enough to get the gist...This guy admits he's tone deaf, but he's likely also a good fabricator, is not afraid of large-scale work and seems willing to listen. Doesn't that make him a p...

Jessie, the "Horn Free Lunch" derives exactly and specifically from "efficiency" registered at frequencies much higher than those ultimately required from the driver in the horn speaker. The horn is there only to provide "gain" at lower frequencies...
|
|
Jessie makes an interesting point with the idea of trying to get ULF from 97 X 2" drivers. Very few small drivers are "optimized" to produce ULF in the first place, and so far the small-ish, BIG X-MAX drivers that are intended for "bass" have not be...

I spent today some time to finish my Multicell as I am not able to look at it if it not black. First that I discovered is that it is irrelevant how it painted at throat as horns is so deep that it dark in there anyhow. Jessie’s idea to fill up the c...

[quote user="jessie.dazzle"]I do not interpret Pham's page to show that he is running more than just one horn system; what I see is an evolution of a system. It looks like, in its latest iteration (under the heading "System Update 9/29/10"), Pham has...

Paul S:DSET is a very high power solution to a question that I only have a very primitive understanding of. It is not right for me at this time.I would prefer if the model etc. of my speakers not be involved in this discussion. I know I am committing...
