[quote user="JLH"]Foolishness is too soft a word to describe the unspeakable garbage the Magico Ultimate is. They have mis-matched impedance drivers, improperly sized horns for the drivers, and made everything from metal. Then they go on an attempt t...

Hello Romy,Thanks for the great explanation, I'm a newcomer to horns, so please treat me gently ;-)Very interesting info, so in essence there are two limits, the real "hard" limit, where you risk damage to the driver, and the "sensible" limit, below ...

Romy, The bass horn project is still going. I have re-arrange the position of the bass horn. Check out http://www.goto-unit.com for most recent pictures. I finally received the GOTO SG38WNS 15" woofer and GOTO SG188S tweeter this week. My next step i...

Quotes from Romy in blue :"...If you are not in very large room and your bass section are not 90dB sensitive then take one of yours left ML2.0, bring it to right channel and drive with it the right’s channel bass system instead of M1.1. It will ...

My approach of the Mid/Upper bass horn and design decisions have been pursuant to a specific acoustic performance target first, quality of construction second, and cosmetic appearance of the finished horn the third. (I believe I was clear in a ...

As I already have written before, I was looking at different bass solutions for frequencies below 110hz with my set-up. As of this weekend I have set-up a new solution and will be evaluating and fine tuning it for the coming days. The new bass sectio...

Merry Christmas!Nice woodworking job on your speakers.I have a couple if questions:Why did you select the drivers that you did?What made you select one horn for the midrange but for nothing else?What process did you use to select the crossover points...

Facing similar issues, until confirmed or disproved by experimentation, the following represents my view:Situation 1):Mid-bass horns aimed generally TOWARD listener's ears: Alignment of the DIRECT OUTPUT of the horn for time arrival to listening poin...

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...

[quote user="speedysteve"]Well, I think
it is horses for courses and the tapped horns are a bit of a different
gigi. I found it is imperative to suffocate the
rubbish that is coming out of tapped horns above say 100Hz - mine are sized to
work...

Haralanov, it had to say, I think it would be all depends how he use that MF driver. Do not forget that this MF driver, I still insist to call it Lowther has very extended HF. That is different type of HF that is coming from “cigarette filter paper”....

Thinking about your options, I would locate the driver at the top inside corner of the horns (horns viewed while looking into mouth), and develop the horn flare from there. See explanations below:Driver located high and inside: "Hypotenus wall" of ho...

Putting The Mid Bass horns behind your head will not work. This thread was about Mid Bass Horns Project, do you thank you will be able to use any frequency above 80 cycles with rear fired horns that are behind your head? That is a Joke. It looks more...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

Thanks The CatI'm posting the pics of the build as I progress so people can see and pass on ideas, that's all. Are you suggesting you don't want horn projects shown on your site? I had earlier outlined the design, including cross-over points etc.I as...

Paul,I'm with you waiting for a bit more enlightenment and less rhetoric on the subject. As you stated if e.g. a Bass reflex does certain things wrong there are some known 'recipes' / fixes to try, and some will work. We would want to utilize a u...

Romy,you did not disappoint my expectation in your reply. Who can argue with the take: "bugger off and do some home-work"? On the other hand, when looking through that "Knowledge tree TM" it's more of a "forest" as far as horns are concerned. So it's...

The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...

Ok, so I'm not really going to talk about the show itself, but more of some interesting things I learned. Yes, I did have a room, but that's not the point. I was able to borrow some speakers from Azzolina. They are of the unusual Lo...

[quote user="Rewind"]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...
