Romy, i hope this post doesn't offend your sensibilities. I am not gonna say a word about the physics principles that have led me to the conclusion that this is something that should be tried ( unless you ask of course ).
The idea i have is...

Good summary, Markus, I would add a few more reasons but what is the point. The key is that bass from back loaded horns is dipole by nature or has a large dipole region. The back loaded horns produce bass similar in behavior of Sun during winter:...

I have a really barbaric suggestion... of course. I can set you up with 8 lLinaeum, soft, live horn, dipole tweeters. Stacking 4 per side should see you at 103 dB sensitivity and 8 ohms of impedence. You can stack them without interference diffr...

Roman, do you pick-up strong FM from the TU-X1's antenna or have you installed an outdoor dipole antenna via coax?

My easy dipole defense would be that I have not yet heard a monopole that does not distract from the illusion due to some other issues, meaning that it would be a case of picking your poison. But I think there is more to it. Maybe I don't like t...

[quote user="Vasyachkin"]the only real questionable aspect here is adding a second set of back firing, inverted phase horns. mathematically speaking it is what the design "needs" but of course the real question is - what does it sound like ? that's...

[quote user="Antonio J."] I have listened to some expensive speakers from B&W, Wilson Audio, Dynaudio, and also owned the SF Amati, you know already. Musically these ones were more musically interesting to me than any of the others, but still wer...

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. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

Richard, I absolutely agree with you that dipole provides a masking affect from many problems but along with illumination of the badly reproduced bass dipoles inject into music a common denominator of… dipolenisness….. and this something that ...

Romy,let me step up to the plate and get shot in the foot or what ever. A lot of what you relate is of course right - BUT, 'where the is smoke - there is a fire" as the saying goes.So, there must be a reason for this 'abnormal' notice of honking horn...

Interesting take on the Altec 820. No way can this be done for 20k. Looks like dipole bass with some attenuation for mid frequencies.Wolf von Langa has a faintly similar take on the Altec 820: [url]http://www.holgerbarske.com/allgemein/fremderregt/#c...

As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ag...

also the phase you mean is actually reverse amplitude without delay. Which, on a 2 feet distance in HF, has absolutely no audible relevance. Its important in either lows or when operating dipole, as the distance of source in depth is near 0 so that t...

Sure, Josh, I have done this, and it does work, as far as it goes. I have for some time used ribbons over 8k, because I like them for top of HF. This one is the only HE, dipole, HF ribbon I have seen. Most efficient HF ribbons are "housed" by thei...

Romy does explain things correctly, in his own way of course.Modern electrical field theory has it that the electrical field attached to a cable, stops progressing along the cable for every vector change in the field. Not exactly a digital event but ...

Romy,I make 6 drivers = 95.8 db/W. You get 3db / doubling of the number of drivers ie 88 + 10log10(6 drivers).That's why I'm going with a bunch of Lambda TD15S (which are sort of a cross between the Altecs cone - paper, curved, foam surroun...

Yes, I was implying the dipole-centric results (open buffers, ports, passive radiators and so on). They all has tendency to “demean” the significance of Sound by introducing the false sense of comfort that reduces the original anxiety and complicity ...

Hello All;Any idea where I can get an antenna connection for an REL tuner. It appears to be a clear plastic connector with holes in one end and set screws to secure the strands of a 300 ohm dipole antenna with another end that plugs into the back of ...

[quote user="el`Ol"]But when the frequency where the dipole acoustic short circuit "kicks in" is clearly below the Fs of the driver, everything "dipoly" that can happen are rear wall reflections with the wrong phase, and that danger is also reduced b...

[quote user="haralanov"]Vasyachkin,in the context of your question, there is a very big difference between bass driver loaded with slow and fast expanding horn contours.[/quote]perhaps. but since i don't know much about horns i can't follow what you...

[quote user="slowmotion"]That is correct, my present setup doesn't speak much under 40Hz, or so. And, they are not very directional down there... But, I am working towards a gradual transition, and I might even get halfway there, one day...... [/quot...

judging from your draving, they appear to be bipolar operating tweeters and not dipole. While I generally do favour the horn approach above all the others,sometimes I do wish the whole reproduction would be less "dry" and bringing in some wide beamin...

[quote user="guy sergeant"] The bass system had the two pairs of drivers facing each other into a 12" wide 6ft tall 'slot'. The drivers were open to the rear. I think this had been put together just prior to the show.[/quote] Ah, the slot-loaded, fac...

Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).What sonic aspects in particular? ...
|

Josh, yes, there
are some techniques to create “space” by artificial means. Revel does it in their
speakers for instance and few others. Some companies inject out of phase sound
in the back of the speakers. To a degree all of it works. It is impor...

[quote user="Joe Roberts"]… our goal for the speaker is "big horn sound in normal sized rooms"--and 8W will do that.[/quote]
I think I missed it. This is erectly what I disagree with. I do not feel that a single driver dipole speaker is capabl...
