I have so much fun today. I sent the whole kids with their nanny
and mom to a Boston children museum along with ants and with grandparents and deeded
to stay home to work on my listening room. Since I did not have good sound
before I did not parti...

that old sails does just control <1khz reflections ... you need to control your mid bass n basic bass frequencies first. [/quote]
I guess you meant >1khz reflections? Yes, it will and it is erectly what I am loo...

[quote user="skushino"] Edgarhorns weren't an obvious choice. Many horns never worked for me. The Avantgardes left me cold. So did the single-driver crowd (I just don't get it....), Altec VOTs, PA systems, etc. But there were some systems th...

OK, this morning I tuned the playback and did some listing, trying to understand what was the problem. Sound was not just bad but it was very strange, it was almost as a mechanical replica of sound. I took my phase meter trying to set horns in ph...

First of all, season's greetings to all. I have been thinking about this issue for a few months now and was reluctant to post a question in case it was premature! There must always be some niggling doubt whether any real estate adventure will materia...

Last and this weeks I played mostly LP records. I have only one arm and one needle setup after my move to new room – I did not decide that what final configuration I will have for my analog. Today, while I am in Brahms wave I played the entire box of...

Hi Cat[quote user="Romy the Cat"] However, here is where the trick begins. Putting the headphones on, playing them along with the big loudspeakers system and adjusting the volume of the “big system” (primary the LF channel) it is possible to take the...

I would like to share that wonderful experience I had 2 nights back when I spent the whole night to juts to listening my midbass horns. I did not do it for two year or so and to hear juts the midbass back as I did it during the post-contraction was v...

[quote user="montepilot"]This past weekend I was able to have an extended listen to the revised Melchiades amplifers. My previous listening session left something to be desired with midbass punch and dynamics. Had I not have heard mini me it may no...

Thanks Romy,[quote]With midbass the total sound of channel is about 20% come from the driver and the rest comes from the horn design, channels integration methods, room integration methods and a few other factors.[/quote]Now I got why exactly midbass...

[quote user="el`Ol"]Romy, are you going to verify the decision of using fragile vintage drivers?E.g. by trying JBL midbass drivers?They would be closer to the design philosophy of the Fane Studio 8M.http://www.jblpro.com/components/maxout.htm#2020H[/...

Jorge, that is good but a few thighs I would like to mention in this approach:
1) What you depict will work with tractrix or conical horn but not hyperbolic curve. The hyperbolic has own “swell” into exponential curve that would make it to...

At recent Nord-West trade show Jeffrey Jackson, the guy who runs Experience Music site, demonstrated his new horn Installation. I know little about it and would like to make some comments about what is feel is obvious from the image.
It is 5-ways ...

This weekend wife told me that I should not do nothing else
but to fix my playback and this was exactly what I wanted to do. Yesterday I took
good 14 hours to play with it, moving boxes, trying to find a good
configuration, making measurements, th...

Simply beyond any criticism. The Purepower bass was something that sold me on the very first unit in June 2007. The very first Purepower 1050 had the same type of bass. What kind bass? Well, if juts did not “improve” it and did not modified it ...

I realized that this thread is slowly becoming the most sophisticated web recourse about Midbass Horn available. Trying to keep the thread educational I would like to introduce to my readers one more objective of my project. The subject is super ...

Last night I spent some time with observing my ULF and I conclude that I am not exactly know what I deal with. Do not get me wrong: the ULF forks fine, sounds fine and the playback is perfectly operational and listenable; it does sound very good ...

Wify was asking me about my ideas about midbass horns at one
nice property that we looked. Her innocent question made me to think. I do look
at my prospective listening room from point of view of introducing midbass
horns. I am not planning to mak...

[quote user="zanon"]My room is big … So how to measure it's size? Just write in floorplan of the entire house.[/quote]
I do not think that we need to measure room size but we need to understand the acoustic consequences of the room size and to...

Haralanov, this is very interesting way of looking about the things. So, you feel if to slice the upperbass vertically by multiple channels then it has some benefits, kind of odd to hear it from a person who advocates a single driver approach :-). So...

I got an email from… I do not from whom, somebody from internet. The guy sounds like build his home inhalation and considering some bass horns. He read at my site about my midbass horn project. He was inquiring how my midbass horns sound and if i...

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...

[quote user="Antonio J"] INTEGRATION that's the clue and that's what I always feel lacks in my room, I mean extreme integration, real integration, the feeling that the recorded bass sound has its own boundaries, not my room's. [/quote]
I do not comp...

Thank, Manolis, it did address some concerns. I think I even know what you did with the MF driver. You were able to get 50Hz out of this looks like horn? This is impressive. The boundaries-loaded horns sometimes allow doing away with the horn siz...

I still remember proposed solution for symetrical TAD 1201 horn loaded midbass sections. Was it to free listener from sweet spot low seat position ? I could imagine that that midbass horn performing up to 1000Hz sitting low on the floor would impair&...

[quote user="Romy the Cat"] In fact I do feel that
my MF and upperbass are very good integrated. But again, I might not know how
different it might be if it was otherwise. [/quote]
Exactly!
Some time ago I also thought my upper bass channel is ...

Hey Romy I read your requirements of a mid bass horn. I am using jabo tratrix KH-55A(320hz) with altec 288 and I want the mid bass to go under that. I would use a trattix round midbass if it was possible. But it's just not with in my abilitys to buil...

Since my left channel along with midbass horn is more or less configured I made today a first rest of the full assembly - with LF section. The midbass does somewhere hear 40Hz and I set the LF section for 34Hz, drove it from B2 via the SMS crossover....

Cessaro ALPHA:
TAD TD-4001 2" driver on tractrix horn with 56cm bell (approximately 250Hz). TAD claims response from 600-20KHz. Given that the midbass is essentially a direct radiator (theref...
