If you look that Jeffrey Jackson’s midbass horn then you can see two pillows stuck into the horns belly. Let presume that the pillows were placed there in purpose. So, here is homework for people who would like to flux their horny mussels: what is t...

When you get a horn that will work i will trade for a couple weeks!I don't think wide band drivers are the ideal way to do things but the most cost effective way to injoy good sound i would like to make another pair to crossover from 3k to 10k.some...

[quote user="Romy the Cat"]The midbass horns dodo fine attack of the short notes but they all delay with decay. If to make an amp that would shorten decay of the fast notes then it would be a phenomenal solution. [/quote]Your midbass horns have delay...

Are there any signs for worsened transient response of your midbass channel due to the sharp electrical filtering?...
|
[quote user="jessie.dazzle"]Is this because of the way you are driving them?When testing my one completed mid-bass horn (AK151 into 40Hz Exponential with 8" throat), and powering it from an amp that drives everything from upper bass to HF, the output...

...if a 50yo 8" woofer could do much more than 90dB at 50Hz with anything approaching 'ease'. Remedies in this configuration are a lot like small 2-way standmounts in that we are trying to get a lot of bass output from something small and excursion ...

Amir, Romy was actually very specific about why he was critical of Melquiades/Macondo. Even in old posting, he made a point of mentioning that he very much knew what weaknesses he had. To be honest, I believe that his real motivations for change are ...

[quote user="msaudio"]I have built quite a few bass horns and found any thing over 1/2 inch ply wood reinforced is all you need, in front of your baffle. If you had ever built a few on your own and had the right equipment to test you would realiz...
|
You mentioned it yourself that the most interesting midbass you ever heard was from corner horns. Why not utilize if you can a pair of K-horns (or clones) bass (midbass really) bins with sort of moveable fake corners? They can be found dirty cheap th...
|
[quote user="Jorge"]Now if you design a TH for 70 hz, you can use it from 35 hz up to 140 hz, and that could match up to your 142hz front Upper Bass horn. With this solution you completely eliminate the need for a Folded horn midbass channel, that ...

While the aftermath of the midbass horn project is not over I am strategizing how I might implement Macondo’s LF section. The leading idea is to bolt a triangular shape sealed enclosure juts behind the small wall that cover the load bearing beam from...

Hi All,This is Ming Su and I am the US distributor for GOTO and J.C. Verdier. I thought that I will share with you about my new midbass horn. As you know by now, Jeffrey Jackson from http://experiencemusic.net/ help me on this project.&nb...

[quote user="JLH"] Other than being completely ridiculous in appearance, this guy didn’t even bother to time align any of the drivers. [/quote]
This exactly what is the most fun in that system! Sometime people do not do the time alignment because it...
|
I generally like what the Polish people did. Of cause from sonic perspective their system with misaligned tweeters is unacceptable but I very much like how they curved both midbass horn and tweeter fame – very tasteful. Design-wise in this configura...
|
Well, it unquestionably much better, still I am afraid that they are trying to spread one ass across two chairs; I will talk about it in the end. The change from what was before was around the frame and upperbass horn. It looks like the guys are tryi...

Thinking further about my "Hanging" inverted Midbass J-horn presented above I asked myself: where is to cut this 12’-13’ horn hypothetic horn. Initially I thought to do it in order to keep the parts smaller to be able to fit them through the doors an...
|
That is funny and I kind of forgot how it is. Got home and plugged the SMS digital crossover into the chain of my new midbass horn. I sat to lie different crossover sloped. The bass from the midbass horn was like somebody hit me in face with a wet sp...
|
A fascinating commentary Romy. I need to get my act together and implement my midbass channel. Unfortunately, my room is not happy with midbass produced in the vicinity of Macondo with broad cancellations in that range but I think will be fine in a ...
|
Jessie, I have moved your post to your 45Hz horns thread but then decided to keep it here as some of my comments would be about entire system not only about your midbass horn. Anyhow, there is nothing there to laugh and it is pleasant to see that som...

I asked Alex who got those tweeter from him and he said that it was Stavros Danos from Cyprus. So, it was the Greek guy that we have meet before on the pages of my site:

Midbass from horn in
small room can be hugely benefited if it bounces but to make the
assembly of horns visually pleasant, time aligned and functional at the
same time is a big question. I do like the notion of Midbass fires t...

[quote user="Romy the Cat"]1)
Since you use the
injection channel, stop using it. The injection channel was a ridiculous idea
with exceptionally beneficial results, but now I have found it better. You have
two Tannoy Red 10 drivers. Use the HF...
|
Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...

The last night I put the kids d and wife and bed and desired
the spent some time with my playback like I use to: listening, thinking, experimenting,
thinking again, smoking a good Padron Family Reserve 50 cigar… OK, I lie to
you. I do not smoke in...
|
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"] What really surprised me was how good everything sounded with no filter on the upper-bass horns, and all drivers connected to the same (8 Ohm) tap; sure I'm getting too much mid-range from the upper-bass horn, but its...
|
[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...
|
[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 ...
|
[quote user="rdrysdale"]….as of now I'm convinced that a compression driver is the best way to go for fast, detailed and dynamic bass. The compression ratio needs to be just right, and the horn needs to be right, when these two are working together p...
|
[quote user="Romy the Cat"] Ok, I do officially like this “Battle Road” hours. Upon many considerations (and there are 4 ways to implement the midbass horn in that room) I have inclined to my leading idea to do it elegant and with time alignment....
