Had a wonderful visit with my Japanese friend. But now she's flying West over the Pacific, and I wanted to add my experience to the TH discussion.The main benefit of the TH is the relatively small mouth compared with a traditional horn. That's all....

[quote user="de charlus"]It is indeed an interesting subject; I am instinctively drawn to it due to the fact that the majority of orchestral instruments - the majority of my listening is orchestral/chamber/classical soloists - produce their own sound...

Charlus, it is not about an expression of gratitude, trust me, I am very indifferent neither to criticism or appreciation. Ironically what you are trying to do is in a way an organic holding a touch of a few audio ideas that I happened to advocate as...

The horn are in the listening room, ready for final assembly, finishing and hopefully lifting up. My carpenter re-measured with laser rangefinder all key aspects of attic and gave me 80% that the horns will fit into the 3D space we designate for them...

Hi romy,Have you had a look at the website recently (site address above in marco's mail), they have very detailed discussion of midbass horn with photos of phase-plug etc. unfortunately it may be only in french ...R Weissman...

Romy I see were you are going With this horn worship for midbass. It is the correct thing to do "But you still will not be happy with the outcome because it does no go low enough. You will not be happy with 60hz. Then you will need something that ...

[quote user="unicon"]Roman, first of all I feel good about your bass horn that's what i have always bin dreaming and if i get the space for it wont even waste a minute I think you already know it or using it ...You mentioned using a foam in back ch...
|

Ah yes that was the thread. You mentioned that the lowther was used too low on the hørning because a lowther could not honestly be used for a midbass. What i was thinking is that due to its design and retarded power to weight ratio it could be p...

[quote user="rdrysdale"]Our bass driver has a 12v field coil motor, it developes just over 20 kilogauss flux density using a low carbon steel pole piece. The exit diameter is 4 inches at the moment. The diaphragm is 6 inches in diameter and made of a...

Noviygera, yes to a degree a short midbass horns is not really
a horn but some sort of waveguide or
bounce-horn. A horn described, if to drop all crap out, by volume of LF equalization
(boost) the horn makes. A larger trout to mouth ratio the larg...

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

I’m new to this outstanding website and I found it has really educational value and antimoronizating information :)
I’m still in the world of direct radiators and I’m looking for the ultimate midbass channel solution. At this time it’s still impossi...

This is very interesting subject.
I expect that tghe new Midbass horns will have somewhere 108dB sensitively anechoicly. The driver is 99dB and the hyperbolic curve has much more EQ then Tractrix and that is more important the EQ that work mu...

user="noviygera"]Romy,
You make
very, very good points now I am re-evaluating this all-in-one horn concept. I
do know one thing that I learned from my current system. Midbass horn that
rolls off below 120 hz and integrated with sub is not...

Hi Roberts, Romy and others,Before this thread vanishes in undeserved obscurity, I have a question or two for you. I understand that the issue is a complex one and should be addressed with more care and paying attention to detail than I am do...

Adrian,
You pretty much said it but do not think that what you said it minor – it is in fact huge, with exception of some rough lathe-work: it is not exactly true but if it was true then it would be irrelevant to Sound.
I really do not know wha...

I am reading through those interesting threads.
I have just won a pair of S2 on ebay so I am interested in horns for them. I have fired an email to Vitavox Peter and I will get his diaphragms. Since my drivers are in UK, maybe he ...

A visitor of my site, presumably it is someone from GOTO, sent me email informing that GOTO made a new midbass horn. My enthusiastic applauses to GOTO as former GOTO bass-horns were very bad and not serious.

[quote user="haralanov"]I think you wanted to say reflection surface, not radiation surface, right? Radiation surface is the surface that is directly attached to the vibration creating element (the voice coil). So the radiation surface of the horns u...
