Ah yes, sorry - that wasn't remotely clear. The drivers I have played with briefly are S2 and field coil RCAs, both have the same 1.5" throat. I was referring to my initial impressions of the sound on Martin Seddon's 160Hz horn (T=0.8 JMLC). Previous...

The idea of using this type of midbass horn seems good, but I don’t see a solution for time alignment of the horn with the other channels. You have a freedom to physical align it if it is placed in the same vertical plane with upperbass mouth, but th...

I wonder, if to embrace the idea that I described in the Maturation Shields article (a few posts above) then how those external horns might be constricted?
They need to be solid and not to be afraid of sun/rain/snow. They need to be acoustical...

[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 ...

Apologies for DIY flavour, but what, I wonder, do people make of the following technique for damping relatively thin-walled large horns, in pseudocode...For horn length x = at throat to at mouth Take a length of y mm diameter braided cable sleevi...

[quote user="serenechaos"]I built a pair of tapped horns, as per John Hasquin, designed to integrate w/ mid-bass horns (cross over ~ 70-80 hz). Loaded in the corners, the low bass is well supported, and, they "dissapear" sonicaly. By that, I mean, ...

[quote user="Kcct82"]I didn't use John Hasquin's tapped horn design, I modeled my own in hornresp for my TAD woofer. I knew I would only need it up to ~55Hz so I was happy to have it flat from 23Hz-70Hz. The lowest crossover point for Behringer DCX 2...

Yes, tapped horns are lower efficiency, mine are 105 dB (not 108 - 110 dB like the rest of the system). I don't even KNOW that SET or Class A is automatically appropriate for tapped horns... Something like op amp driven PP in class AB might even wo...

There are at least three benefits of using a compression chamber in a tapped horn design.1.) When using push-pull woofers with a compression chamber second order distortion is cancelled. This effect is very audible. You must hear it to understand...

Well, be afraid to get what you wish people say and it is exactly what happens in this thread: last week I expressed curiosity about the tapped horns and today I have more information about them than I wished. I appreciate John, Robert, Tom and ...

Hi
Maybe you should rent the apartment over you? Nice place for sub horns,
with opening in the ceiling like our japanese friends do ;)
I am planning subhorns with floor-to-ceiling mouths in each corner of the front wall of my listening room, w...

I’ve never heard of the “Hut on Fowl’s Leg” before. It is an interesting folklore tale. However, I still laugh when I see these horns. Other than being completely ridiculous in appearance, this guy didn’t even bother to time align any of the drivers....

Jessie,
I was about to replay to your post and suddenly John Hasquin posted his reply that said exactly what I meant to say. In fact he has much more credential to assess the validity of you attempts then me as he actually build the horns. In additi...

Chris, yes and no. The phase shift 90 degree of there perhaps but it is not really relevant. If we have a very low frequency horn, crossed low with high order crossover and the entire horn is delayed at 30ms then we do not have the same negative impa...

I got my pair of 1.5” to 250Hz trx-horns that I will be trying for my “Fundamental Channel” experiment. It will take a couple weeks to paint the thing and find out how to mount them. For a time being I have a few very interesting proposition how to c...

Hello Romy,Thanks for the great explanation, I'm a newcomer to horns, so please treat me gently ;-)Very interesting info, so in essence there are two limits, the real "hard" limit, where you risk damage to the driver, and the "sensible" limit, below ...

Well, a lot of horns are put into box enclosures of course. This is really a complicated subject. The baffle must be dealt with in a manner similarly for all loudspeakers so designed of course. More interestingly is the potential fo...

Really, this is too funny!I actually thought that everyone who's seriously concerned with the matter knows that everything about a horn affects the sound, including the material the horn is made from. Hell, that's one of the reasons I gave...
