Indeed, if the horns are doing their job then there will be some very powerful vibrating going on up there, for better and for worse.Decoupling the horns would require that the structures of the horns themselves and their support members have solid p...

About the proposed attic-mounted 40Hz horns: Is there an elephant in the room?I'm speaking of the proximity of two horns, relative to each other, and the possible consequence; namely they may end up working as a sort of mono horn... A situation furth...

You mentioned it yourself that the most interesting midbass you ever heard was from corner horns. Why not utilize if you can a pair of K-horns (or clones) bass (midbass really) bins with sort of moveable fake corners? They can be found dirty cheap th...

Moreart Most people on this site only badmouth things they don't understand. From what i have read the last few years on romy's site, there is a leader and a bunch of follower's that have no clue of audio basic's in sound reproduction. The leader j...

One of the challenges I see for my midbass horns is to minimize hf output. The goal is to operate the horn in a bandwidth where it can cross to the higher horns, and have each horn function in their best sounding manner. My drivers are Altec 515-16...

Why not enclose it in a horn shape? After all, it makes sense for the facing surface to be circular rather than square, and a cone will have the best structural properties, as well as having the closest kinship with the rest of the stack....

I mean for all intended purpose horns has restricted radiation pattern and usually larger size then direct radiators. I do not see any needs to use horns for private outdoor installation. In our house we have a lot of outdoorsy live and I did thi...

I suppose something like this, but attractively sculpted, and without the vertical partitions, could be an interesting omnidirectional horn to put in a garden. Rather like a mobile sculpture, but with its dynamics in the auditory range. It would cert...

A few months back a audio guy visited me and after a listening session I asked him if he can report any problems with sound. He reported that he hears a slightly more prolonging decay at upper bass then what he suspect to be. I knew about this effect...

[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 ...

[quote user="Romy the Cat"]...my light woofers would not be the optimum solution and I might need to use 18”-24” woofers.[/quote]Hello Romy!At least for corner horns I think I can say that lightweight drivers are the better solution. HBM's corner hor...

Firstly, thank you to Montepilot, Paul S, KLegind, zanon and Romy for all your thoughts on the Zu Druids. I recently tried high-passing the Druids at various frequencies and using a pair of Wilson-Benesch Chimeras and various amps for LF and uppe...

Actually, you are the only know to me person who understood my “misuse” of word “Tractrix”. The Altec metal horns are a nightmare and that is one of the reasons I can’t even remotely approach any default Altec installation. I addressed it in here: h...

[quote user="MusicLover"] IF you can "hear" SS amps, Romy, then your system must not be well set up, and be sensitive to the frequency shifts caused by tube amps. SS amps have NO sound that humans can hear. [/quote]

Ronnie,
Very nice, though I do not know where you would like me to move the thread. (It looks like it’s OK where it is). There are some comments that I might to pass.
You decided to go for a large MF driver. This is fine if you like it but I ...

I've had a long-time desire to replace my Edgar 80hz midbass shells with a better performing solution. My Edgarhorns arrived in 2005, and I made incremental improvements over the years until now they have little in common with the original Edgarhorn...

{let just look at the horns: 60Hz-500Hz-15 kHz}What does this mean? THere seems to be three horns. Does the above mean one horn covers from 60Hz to 500Hz, the middle one from 500Hz to 15K and the last one from 15K to upper somewhere. ...

Well, when we are talking about Cogent we need clearly differentiate two things: the Cogent’s drivers and the Cogent’s installation. The problem is that since Cogent’s drivers are something so called “compression drivers” then their performance might...
