[quote user="jessie.dazzle"] There should be no danger in running the S3s down to 500Hz; I am currently running a pair of S2s (same diaphragm as S3) down to 450Hz, 1st order, no problem.
The system is in a room that measures around 80m² with a 3m-h...

Well, first of all, I would like to mention that I edited your post replacing the link from eBay images to the link to the post which features the same images only hosted on my site. I did it because eBay listing will expire in 30 days and I do not w...

[quote user="el`Ol"]Romy, are you going to verify the decision of using fragile vintage drivers?E.g. by trying JBL midbass drivers?They would be closer to the design philosophy of the Fane Studio 8M.http://www.jblpro.com/components/maxout.htm#2020H[/...

[quote user="msaudio"]49Hz To 52Hz will be your peak, so the best you could hope for would be 3 hz below that flat with a perfect tuning of your length of your horn and back chamber of your box housing your woofers. If you shoot for the free air low ...

[quote user="TonyB"] So do your horns have 115Hz flare frequency? (and have the rear chamber tuned for 115Hz as well) [/quote]
They are 35”. Do your math. The back chamber tuned at 115Hz.

Yesterday I listened for a few hours again, including Bruckner 7 and a new-to-me, (old) East German, "Chamber" rendition of Ein deutsches Requiem. It has been hot (for here) for several days and electricity was not so good. There were some nice mus...

[quote user="steverino"]My point is not that separation per se must always be maintained but that the character of the music determines the degree of optimum separation or co-location. For example the first violins are grouped together for a reason s...

I guess you have heard a more detailed speakers then. Your collection seem rather extensive. I never meant the Fane S 8N was overly detailed, just that it my paper horn the detail was gone, so I will not try that again.I share the process because...

I bought a few Linn Records own recordings of Duisburg Philharmonic Orchestra, Scottish Chamber Orchestra and Dunedin Consort. They pushed them as “Studio Master” but they are WMA files – means the re-rendered compressed files – very sad.

Once again, let make it the last post off the subject of the 5-chals Milq.
I think it make sence to start from 370Hz-400Hz horns for S2, targeting it for 1000Hz. Then the lower bass horn, for instance the 45Hz, however it should have a chamber of m...

...if you want to use it "pure" as it were, without any in-between equalising. Or you could tailor the amp accordingly. I would see a lowther working well mid-high rather than mid-bass.My experience is limited, however, to EX-4 used with wizzer in a ...

Well. It will be tonight – I will be trying to drive through the horn signal and to see how it will drop main resonate frequency. This will give the idea of the back chamber size. The 5 and 6 sections are not glued yet – it will be gone upstairs, oth...

Here is the subject that makes anyone who does what we are trying to do wondering: do remover the screw from wood or not. Our leading position is the screw will be removed. We use long 5-7 inch double threaded screws that bund wood stronger than regu...

[quote user="jessie.dazzle"]Wow, 6 x 15" drivers (!!!); though the curved profile certainly imparts rigidity, I'm guessing this horn must resonate more than a bit (no bracing until the mouth) -- but I like this thing.
