I've been thinking; rather than placing the mid-bass horns off to the sides or above the rest of the horns as in the first two images below (a CAD model of the horns in my new place); a plan which implies accepting imperfect time alignment...Ori...

HI "Hifiordie" I want to tell the readers here that this guy is seriuos and has some serious talent.Unluckily for him he has been bitten by the same insect that got us and is obsessed by horns, please do listen to Romy and try to balance your life b...

My current speakers are Edgarhorns with the straight 80hz upper-bass shell. The bass never sounded correct to me. The problems with Edgar's mid-bass are well documented at this site and elsewhere. I tried some simple modifications to the crossover...

[quote user="angeloitacare"] Of course, Avantgarde with their price tag never will be for mass consumption. I offered Holger then to see If I could commercialize his horns in japan, Do u know how much was the dealer price for a pair of trios at that ...

It sucks – whoever builds horns too damn far! I need to see my congressmen to lobby lowering taxes for horn users of something like this….
Anyhow, the “erenechaos” comments about the “soft bass" is a good sign, though of course to equalize the...

It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...

[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 ...

About horn body resonance: I used to doubt the need for mass in horns; after all, how much energy can a flimsy paper cone generate? Still, I went ahead and followed the advice of others when building mine, making them very strong and heavy. With ...

I think this post need to have an epigrapher:
“We knew what we wanted to hear, and so we developped, and developped, and developped... In hundreds of small and bigger steps. Over thirty years. Till we were "there" where we always wanted ...

You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

TwoGoodEars posted at his blog a report about is listening session or some kind of installation. I still have no idea who’s installation it is: Jean Hiraga or Be Yamamura. Nevertheless, I think it very much worth to look into it.

Quotes from Romy in blue: "...Anyhow, I do not know at which stage your project is what I think you are somewhere in a process of integrating the drivers..."I would like to stabilize the system, and listen to the existing horns, while ...

[quote user="moreart"]Hello,i made a few bass horns for home use:look on my HP [/quote]Moreart, Behave. What your “bass horns for home use” have to do with pro folded bass horns? Also, no offence, your horns for home use are a bit ridicules and VERY...

I would turn upside-down mid bass horns ,mount drivers in Heavy box and cover plastic (ABS ?) horns with very thick layer of stynthetic plaster (the one LeCleach is using to "cast " his horns .So now he'd have horizontal J shape and it would be fairl...

One other nice thing about floor or ceiling-mounting the lower-bass horns is that you wouldn't need such a huge living room; the space would be easier to load (sonically), and you'd have a much easier time finding an appropriate house. Romy wrote :"....

The exceptional 15-inchers would be two fitted in two categories: the bass 15-inchers and wide-range 15-inchers. It is imposable to think about the exceptional and wide -range 15-inchers and do not mention the 1946 -1973 production of the Tannoy Dual...

It seems that I do agree with you about the sound of compression driver midbass.. at least from what I have heard in my own room.. I have heard the big ALE drivers you mention on a bent steel horn similar to what ALE builds, but of the owner's design...

[quote user="Romy the Cat"] 1) Horn loaded drivers are narrow-bandwidth transducing system. The wider range a horn channel covers the more it conflicts with restrictions of own topology.
2) All channels shell have strictly parallel axis

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

HI,dipol bass, not happend in nature,yes different listening, because of reflections,below ~300 Hz the listening room is dominat,you listen more the room, not the single driver.If you look my horns, the double horns,you can see my OMNI-bass experienc...

I haven't really thought this through, but if I were doing upper-bass horns again, especially if cut using a numerically controlled router, I might consider making tham oval, which would permit going for a horn with a lower cutoff (larger mouth) whil...

I find that one of the most interning and stimulating ideas that you expressed was your experience with your bass horn

About the bass, which must be lacking in such a construction:I once made an experiment with something similar (single "cut" horn with "mouth" directly adjacent to the driver), and subjectively there was much less bass extension when I placed a barrie...

First off, I forgot to mention an interesting observation: Before running the sweeps (previous post), since the drivers in the upper-bass horns are new, I decided to verify/optimize rear chamber volume (they are easily adjustable)... I wasn't expecti...

I need to say that with all huge advantages I have in my room with my midbass horns there is something that lost. I lost a great impulse response that I use to have on my old room with my direct radiating bass array covering up to 70Hz. I did not...

Paragon-You missed the point. The topic of this thread relates to bass horns inside residential homes. My post remarked on CH Audio's unique approach to solving this problem. My comments were unconcerned with listening to this speaker, perceived b...

This gentleman's set-up makes me think very much of the one I have in mind for my new room in due course. Whilst as Romy points out, the room might well be on the small side, it has a very high ceiling (say 4.5 m) that in my mind always presents fabu...
