[quote user="haralanov"] Some time ago I also thought my upper bass channel is flawlessly integrated, but when I added another, symmetrically arranged UB driver (over my WR driver), I quickly understood the new configuration is MUCH more expressive a...

Hi Keith and congratulations for your new babies... I'm truly jealous of your room size.Me too, as I previously wrote, assembled a VERY similar rig, vastly inferior to you welded supports, any, using the same approach: S-150, S-3000 and S-400, respec...

[quote user="Romy the Cat"]Twogoodears, What you are experimentation now has yet nothing to do with DPoLS. You deal with the relatively rudimental ceremony of speaker positioning. It is not even close to the subject of DPoLS but it is also greatly ne...

[quote user="Ronnie"]I'm curious about how you set up your horns in the room.From photos it looks as if they are fairly close together, compared to the wide setting you suggested I try, while our room dimensions are fairly similar?When I started push...

This is a very important question as since very beginning of the projects it was questionable if I would be able to get away with the back/top firing position of my midbass horn. So, as now, when the midbass horn project is over and horns fully i...

Considering the conclusions of my recent experiences that I described in the following thread:http://www.GoodSoundClub.com/TreeItem.aspx?PostID=6876I would like to share some of my observation that the people who would g...

[quote user="tuga"] Hello Romy, Could you elaborate a bit on your experience with the toeing in of horns subject. My square mouth horns are probably even trickier than round horns to fine tune as the higher frequencies seems to radiate in a flowery (...

Hello Romy,The tapped horns were easy to construct so I made them while I was working on the midbass channel. I can't really comment on how good tapped horns are because I have never heard other 20-35hz capable systems... it does provide amazing SPL'...

Jessie,
Unfortunately it is in my view it is absolutely imposable to predict anything juts based upon the CAD modeling. The entire criteria that you for founding the right positioning of your instantiation are wrong, at least in my view. You use the...

Yep, if I do it then I will do it right: with a single driver, with full length, with proper mouth, with slow profile and if it had curve then it will be properly linearly expending curve, not with the resonant chambers or with steps. The problem...

One of the problems with horns is the inflexibility of frequency cut-off: you are limited to a discrete number equal to the number of horns you have. This makes experimentation difficult without having an absurdly large array of different hor...

Hi Romy:as I don't consider the thread as emptied, yet, I'd wish to add some thoughts after more days of listening to my system.I re-read an half-page chapter in French from Jean Hiraga's "Les Hautparleur" essay, concerning time-alignement and p...

[quote user="haralanov"]Come ooon, comparison between the radiating area of direct radiator vs. the area of horn’s mouth is too amateurish even for some diyaudio.com level simpletons… It is as naïve as saying Leonardo’s Mona Lisa is simply 100 grams ...

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet. That what I ...

Hi Anthony,I am amazed by the work you have accomplished so far and love your stands and horns stacks.Two comments though in term of overall esthetics although I realise that having spent so much time on this it may be too late to make changes.I woul...

[quote user="Jorge"]I guess you cannot say you listened to a horn system if you dont have an upper bass horn. [/quote]Yes, I can very much concur with it. The upperbass and MF horns set the frame of the sound, sort of sonic skeleton upon which everyt...

[quote user="haralanov"] Yes, but you are familiar with the compression driver and horns. How could somebody control the size of the audio window, formed by his midrange channel, using horns? If I remember correctly, you chose your Vitavox S2 driver ...

I'm of the opinion that listening room aesthetics play a big role in enjoying music at home. This is self-evident, but over the many years playing with audio, my listening room has become incrementally cluttered with "audio detritus". It's ugly and...

My room, is 16 to 17 feet wide, 27 to 28 feet long by 12 to 14 feet high with all walls splayed, with a combination of absorption and diffusion on the walls. All electronics are fed electricity by three pure power units originally recommended by Rom...

I changed the new flash at my site to “Ok, the midbass horn project is successfully over. Over 3 months, over 400 posts, over 180 pictures… all publicly available…” The project started physically on July 16, 2010, ended on October 28, 2010. The prepa...

[quote user="Romy the Cat"]OK, I need your guys to participate in brain storm and come up with an idea how the hell we might lift those horns up. They needed to be lifted 10-11 feet up and then very precisely, almost surgically slide 13-15 feet into ...

[quote user="be"]I have a two horns covering from around 150Hz and up, with a crossover frequency around 700Hz, So my system is probably less sensitive than yours with the many chanels and higher crossover frequencies. But I have changed my mind and ...

Yes, Gregm is right we have no idea what is behind the bottom “bulge” and therefore any speculation and accusation are “correct”. Nevertheless, from what I have tried, if I “design” this horn and had a desire for whatever reasons to preserve the “bul...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...
