[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...

Romy's quotes in blue :"...Discussing the Jessie project we multiple times mention the idea of the large midbass horn hanging above MF section... The rational was to have it positionally contra-react the output of the upperbass horn... But do we au...

[quote user="be"] Instead of defining the ULF range from the reproduced instruments, it is much smarter to do it based on the first resonance frequency of the listening room, because the frequency response of a closed room has a 12dB/oct rise in ...

[quote user="oxric"] In my mind, and given my specific circumstances, the question of strategy is inextricably tied to the resources in terms of time, efforts and funds that I will be able to devote to this attempt to achieve what I have in mind ...

[quote user="Romy the Cat"] The major minor thing remains to find different lower bass. I said “minor” thing as my lower bass is not bad, in fact I do insist that it is very proper lower bass as I did set it up lately properly…..Despite that I in...

[quote user="jessie.dazzle"]In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. Be...

Yep, indeed, it looks very nice. The 8 sections of bass line
array look visually slightly overweening but I think when you put the upper
bass horns in place it will visually balance the things out. I feel some sort
of envy to the way how you plan ...

[quote user="Paul S"]Romy, perhaps your ScanSpeak arrays are a +/- natural fit for mid-bass? If you used them for that you might also push them down a little until you got your ULF solution. The "nice" thing about this is, you might use something r...

[quote user="Romy the
Cat"] If I defeat the hardness by dropping of the output impedance then I
would understand what is going on but I minimize the hardness by raising the
output impedance!!! This is very interesting and I need to think about it ...

[quote user="ulf"]Let me tell you a bit about how an why we designed the midbass horns the way we did.A few years ago we discovered the tractrix horn for MF use. It was really the most important improvement so far. No more honking exponential horn so...

Klaus,Yes, I assumed that you had found the spec sheet; I only included the link for the convenience of others following the thread.Klaus wrote : "...whats wrong with 9,9"? its rougly 55% of sd? you think, 43" is too short for a 62hz h...

Somebody in this there warned me that the fiberglass pipe wall finishing that I employed on the wall with my midbass horn, behind my listening location might be environmentally not healthy. I have very high sensitivity to fiberglass and one singl...

[quote user="Kcct82"] Hey guys, I bought the Goto 505TT with S150 horn brand new over 2 years ago. Guess what? I'd still be in sonic shit if I followed the 200-1000hz "recommendation". The 505TT does not perform well below 400hz and when I final...

Murat,
I was looking at your midbass horn design and I am wondering, how are you planning to time align that long midbass with the rest of the channels that seem to be time aligned. I mean, currently the midbass is physically 4.3m behind all o...

[quote user="Romy the Cat"]I was thinking about the throat of my hypothetic midbass horn. This is complex, controversial and it has pretty much no answer, at least in the formeat I ask it. I will share my thoughts with you.

+++ Going back in time to your Super Macondo with the midbass horn, I'm wondering how did the big horn influence your perception of Macondo sound if you remember?
Yes, it is very very good question and essentially the question which r...

I very much do not mind to try the biggest Khorn bass
section with my setup. I am trying to figure out how to do it with buying the damn
thing…
I need to say that the best midbass I hear in my life was
from Khorn, well not from Khorn itsel...

Hello again, Romy.. let me see if I can clear some of this up....
first, you are indeed correct on your horn thoughts.. but some clarification is in order...

I think my dysfunctional one 15” driver in my Midbass was
for a while and THAT was something the make me to feel that I need to move
Macondo to 9-9-1 position. With the recent changes (recovery of a woofer,
recalibration of channels, EQ of the mid...

I meat with a local gentleman who runs North Reading Engineering.
He turned out to be quite intelligent
with whom is stimulating to bounce different design ideas. We might try the K-Horn
with Vitavox drivers, which would be the same as CN-191 bas...

[quote user="Romy the Cat"]Last night I did an interesting experiment. I took the bass towers,
just 4 driver per side, crossed them at 90Hz, line-level and drove them not
with the Milq’s bass channel but with SS Yamaha B2. I use it with the tube cr...

Jessie, I pulled posts from Macondo Axioms thread and encapsulated them onto a new thread dedicated explicitly to your project. I hope you do not mind.

Why can't you just stack them inserting new horn in between midbas and midhorn and keeping your original arrangement? Since your midbass sits on the floor, the tweeter still should be on resonable hight.I would transform your full range Melquiades fo...

My string quartet have just spent 6 days recording haydn and being assaulted by nasty Genlecs.

What I seek to know is: how did the midbass woofer Thiele-Small parameters change by cutting them in half to fit into the half-moon throats..?I'm Horrified nobody has brought this up yet!!http://www.youtube.com/watch?v=NzJ7Km1tXKI&feature=related...

I think it's already too late for that. A man should not go around and listen to stupid horn installations which can screw him up for a life 0).Robert , can you say why 65Hz truncated tractrix and not rectangular half space hypex or expo horns if you...

Hi, can you tell me(us) how much you pay'd for the mid-bass horn please? I may try this myself as I have been waiting six years now for a 15" midbass horn plan that is suitable with no luck ...thanksr weissmanps. Oh sorry I just found the price pa...
