My minimal distance between front of the upper bass horn and listening position is irrelevant as I set the proximity not according the upperbass but according a vertical shifting of HF image. Under a normal circumstances I might be as liitle as ~7.5”...

because floor josts support and extend the walls (they are solid 2"x6")so just screwed the board tightly to them. Because I needed the boards only within 10' so I have 3 rows of 5' +5' with the seam in the middle. I cut the second layer of bards so ...

[quote user="Ronnie"]The next big problem with sound here I think is a difference in sound level between upper bass and MF/HF.Upper bass seems louder (and ought to be). Would you help this electronics-handicapped guy to pad down the upper bass horn w...

Interesting. I wonder whether I actually did the Pussy- or Wilson positioning.I found 4 tiny hotspots around the whole room (for one specific vertical position). The boom areas were large (or perhaps there were many boom areas, close together?),...

JD,In the case of the mid-bass horn, the throat transition does not affect the sound enough to worry about IMO. Due to the narrow bandwidth (100Hz - 1000Hz) the step transition between the woofer cone and horn throat is acoustically invisible. I...

[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

I've been having love/hate relationship with Lowther (and its siblings) for several years now. As you all say, it has many problems to use as a full-ranger. Right now, my set up is a 3way multi-amp, Lowther (Reps 1) in Medallion cabi...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

Here are some photos of Martin Sedon's 204Hz and 340Hz Le Cleac'h horns, which likely have more reasonable shipping charges and fit through doorways, etc. better than the 160Hz version. They have a T-factor (expansion rate) of T = 0.8, which was reco...

I gave another run to Vitavox S2 with electromagnet and while I was listening I come across to an interesting observation. I screw the S3 in 330Hz horn and was trying to run it with 500Hz crossover point. It is pretty standard configuration, the way ...

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...

Hi Romy,
Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405....

Jessie, there is another solution that you might consider, that might be viewed as compromise for one-side as might not be view is compromised from other side. If to allowed ourselves to close eyes to midbass timing-integration and if the geography o...

[quote user="Jorge"]Andrew,Dont buy all the drivers at once, I would get only the upper bass horn drivers and maybe the mid drivers, you will have to play around with these for a while before things start clicking toghether, by then who knows, ma...

Herman, I am glad that you feel better about sound from your midbass horns. I do not know what damage digital amps incur but even your experience of hating the sound of those horns to falling in love with them just after changing the amp do suggests ...

How did you determine that it is the horn. What makes you think that you can damp a horns mouth at 200 Hz. Have you never read what a room does to frequencies under 400 Hz? If not, check this site out: http://amroc.andymel.euMaxx, I think that you ar...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

I mean,
does anyone really expect to straight away come up with a "horn
profile" via math (or voodoo) and then just turn or cast it, bolt on
the driver and, voila?If we talking about upper-bass horn I think yes, via match.I reade...

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA horns or horrible acou...

IME (i.e. some pm's one dx), the Ex-4 sounds the most civilised -- and this, only up to ~10kHz or 1-2kHz lower.It doesn't sound bad in a tractrix, unlike Paul S' experience with a dx4.A horn is also useful to provide some extra spl (106 spl at 1+m wi...
