Macman: Maybe your tapped horns were too small. Speedysteve is absolutely in love with his, and you and him have a very similar setup with your 15" upper midbass horn and all....

It is a shame that I keep finding threads about a 300Hz compression driver channel, that ends abruptly. I have been trying with a not-so-exact Goto S-150 replica (~1.7m deep, 75cm diameter mouth), and I know of another fellow in Sweden who tried the ...

Tonight I finished two
horns at once. One was a shortened Goto S-150 horn that now has a
Fane S 8M, without back chamber so far. Dimensions are now 1.1m deep, 11cm throat, 75cm mouth. It is replacing the Avantgarde
Trio midbass horn r...

I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....

Turns out we were in agreement in 2009: http://www.romyhome.com/Forums/ShowPost.aspx?PageIndex=2&postID=11289#11289Have you changed your mind about such a horn that you propose, or do you have any more hints before I build it? Here is a nice exam...

I will check it all soon and come back. :) Then I will know how foolish it was.
I wanted to see if anyone had any new ideas....

You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

Crossing the woofer so high is not really a fair comparison. The compression drivers needed to be in a bigger horn, and possibly be replaced with a driver that does 100Hz for certain. ...

My work to make the Fane S 8m work, continues amd I have yet to hear my midbasshorn built perferctly according to Romy-specifications. I will continue because in early trials there was something I did like. I guess I will just end up with a measly €...

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...

Maybe the upper midrange horn became like a paper cone speaker. Best sound I ever made, and it looks like this. It had the same ring to it as the magical SABA fullrange speakers - made of paper. But below 500Hz, I must use solid wood. The Fanes are t...

I am looking into building a 45 tube SET amp and I keep reading about how important a good output transformer is. I read that cheaper output transformers like Hammond can be okay for mids and highs, but it will also reduce bass performance. If on...

I built a prototype of a Avantgarde Trio in newspaper and tape, with the Beyma CP380/M, Community M200, and the Fane S 8M, and I also used a Behringer CX3400 and a 45 tube amp. CX3400 is soon replaced by digital active XO.Paper may have made the midb...

Last time we wrote you thought I should focus less on tweeters and more on midbass.I am not done yet, but I have found a very nice midbass solution. Somewhat unorthodox, maybe.I have come to love police sirens! Without having A/B compared it to a pai...
|
|
Yeah, I know it is just guesswork until the Fane S 8M and the JA6681B are in place in their respective horns. Your ideas around fixing the midbass and mids first, I have read before and they seem sensible. We can stop here, and I will finis...

I kind of got stuck in selecting an upper midrange driver, above 2kHz. If a driver is going to screech in your ears it is going to be in these frequencies. I was never really satisfied with the range of 1" compression drivers I tried. That is wha...
|
|
Yeah, they are my own experiments so I am the only one that need to care. They are based on your earlier work, so I felt like writing and tell you what I am doing with your ideas. The drivers we use may be superior or inferior. As long as mine are t...

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...
|
|
Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...
