user="noviygera"]You provided very good starting points on the driver
selection and I am also corresponding with a gentleman that may help me with
actual horn design. I have found a couple of drivers that seem to work based on

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

[quote user="Jorge"] This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 kh...

Of cause your reply does not cover the subject that I was asking, which is fine, I do not mind. The subtle point that I constantly was trying to make (and that looks like escapes from understanding of the people who are afraid to use the term Lecleac...

I'm very inexperienced but I still try to observe things around me carefully. Here's what I'm getting at what can be potentially pretty good.. Well, all I can really say is I've been mostly interested in the design implementations of companies such a...

This is a good example of a CNC horn. This is the Carfrae I was talking about. MDF Upperbass horns are made in sort of the same way, but you do have to cut the angles on the Lathe. (or leave the steps like a The thing is it is not really tridimensi...

I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...

[quote user="Paul S"]Sure, forget the sales pitch, but some of similar might be good for fairly wide range MF. However, based on the sound sample, it's hard to say much about this one, apart from what looks like an extra load of multiple whizzers at/...

Hi The CatI forgott to answer your q, what I do.I 'do' management...heading up a team of folk for a large social services charity in Sydney. I cover training, occ health and safety, payroll, volunteering etc. We have 2000 staff.My interest in audio s...

Too late now for points, but just the other day I tried to imagine your plan. and I was pretty close.Actually, it is a bit like what I have going now; 15" Eminence bass guitarr woofers in a sealed 3 cu ft cabinet,Oris 150 with 8" B&C midrange dr...

[quote user="Romy the Cat"]In contrary, at higher frequencies dipole might work fine, but no in bass. The Cat[/quote]
IMO you can never get realistic imaging from dipole.Here is a very detailed description of a dipole horn for the BG Neo 3.http://ww...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

i am not at all intentioned to make a horn speaker to get rich. i dont think abought this at all. for me its hobby. its abought to have fun, and to get as close as possible reproduction of live music. as close...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...
|
|
Hm, good point. They indeed might
be from UK. Anyhow, I did have Fostex super tweeters. I think one the cheapest
(wish was the best) and one second from their best. My experience with them irrelevant
as it was long time ago and I because I used at...

While I am waiting for the attenuators I worked on the frame and changed it to a metal frame.It is sturdy and height of the channels can be adjusted in both axis.Romy, may I learn what your crossover points for your channels?My midrange channel is be...

I too want a monitor speaker to play with, especially for amplifier experimentation.I put another 4" Fostex in a sealed "box" (globe actually) and crossed it over at 150hz to one SS 25w/8565 on the side. Wishful thinking? -Yes.About 88-90dB sensitive...

Romy is being very kind to me and not shouting at me for wasting everyone's time.Paul, I really do not think that lipstick on a pig get's to the heart of the DX 4 transform. It's much more like a stick of dynamite hanging from the pigs lips and...

[quote user="jessie.dazzle"]I do not interpret Pham's page to show that he is running more than just one horn system; what I see is an evolution of a system. It looks like, in its latest iteration (under the heading "System Update 9/29/10"), Pham has...
|
|
I tend to think that we are not copying Romy, but more that he has generated a school of thought on audio and yes horns speakers also.I too have a system following some of the Macondo Axioms, but have used all diferent drivers.As with other drivers, ...

"Meant to be?"
With 100.5 dB efficiency in quarter space I plan to use a dedicated tube amp. Yes, some people use high powered amps to see how loud they can get Def Leppard, but I don't see any reason to. And some tapped horns...

KM, I don't know how you come up with the belief that I conclude that "it's a bad performing driver." Either the 138, or the earlier 120... Or that because I didn't use 120s that i haven't heard them. And as ever...

ScanSpeak's 4.5" mid looks nice, but it's still 89dB http://www.madisound.com/catalog/product_info.php?manufacturers_id=148&products_id=917 Eton's 4" Symphony looks real nice, but it's only 88dBhttp://www.madisound.com/catalog/product_info....

Yes,I then did understand why you went into Bert and business and connection with sound (it works well as a general example). I don't know how you came to that conclusion of Bert fits into this model though. I didn't-- aft...

[quote user="mats"]I have found the T90A to be reasonably in-offensive with JBL 2435 Neo/Be compression drivers. I use them with relatively small caps, currently 0,3uF. The effect is a welcoming of a higher frequency palette that to my ears does not ...
|
|
Yes, all you said about the Fostex and heavy mouth MF seems reasonable. I don't know what's wrong, but I get the feeling that it's sort of hollow-sounding and could be much more loaded. I'll finish the horns completely before any final conclusions.In...

[quote user="anthony"]I had a look at the website and the AU stands for gold (from the periodic table) not Australia. Plus the prices are in pounds not dollars. Interesting turning them in walnut though and I agree totally about the "horns underwea...

I have finished both big horns enough to listen in stereo, and the throats are now much smoother.I'm not using the MF horns, and have been listening all night. It has been a remarkable experience! (well, the inner-me objects and claims there's nothin...

Romy, Not sure I can add much more.... you'll find out yourself of course. Overall, I can not comment on the "enabl" treatment beyond what, Dave, Chris and Bud have said (Dave and Chris are the Planet10 guys). I think I would have tried th...

Which values are you after? If its the crossover points, here they are, they ay be indicative for you;dual Tad1601b's in 298lt br boxes - open on bottom to 120 Hz, in a range 90 to 150 Hz ~12 dB (three different settings can be chosen, according to r...
