[quote user="noviygera"]
For me personally, midbass is the most important frequency range when it comes to sound reproduction. I believe you will be on the right track to focus on this range because so often it is overlooked and treated with super...

It is very habitual for the internet audio hoodlums (or for males generally) to report the accomplishments of their “hobbies” without any references to the actual accomplishments. In context of audio it might be applied to habits of posting images of...

[quote user="Romy the Cat"]Tax,
do not go over yourself with “building paranoia”, looking for drivers, horns, boxes and etc. If you are looking for 80Hz to 200Hz range (you will need higher upper knee for AG Dou) then you do not need a bass d...

Romy,
Thanks for the thoughtful writing... Sorry my response is not exactly "time-aligned"... I've been meaning to reply for the past few days, but my other life has been in the way...

Ok, Andrew, this is allergy something. I would highly advise you in future before you post any discrete updates, questions, and ideas about what you to inform about the holistic objective of your project, sort of a view from 50.000 feet...

[quote user="Paul S"]Scooter, many houses in the Northeast were roofed by people who understand how this works, and the first few courses of shingles are "underlain" accordingly, to preclude such seepage.
In Romy's case, I believe he could sim...

Romy, i hope this post doesn't offend your sensibilities. I am not gonna say a word about the physics principles that have led me to the conclusion that this is something that should be tried ( unless you ask of course ).
The idea i have is...

[quote user="guy sergeant"] Of all the manufacturers you could be poking fun at you've chosen two who actually care about what they make and sell. [/quote]
I do not think any manufacturers “do not care about what they make and sell”. They all do, or...

Thank you Romy,
<<The multiamping with Super Melquiades was made with intend to optimize the output transformers and to eliminate the interference between the inductance of the upper bass driver’s coil and the MF driver. I still use the speake...

No, the speakers like Altec 19 have time miss-aligned drivers. The majority of 3-4 way horn speakers with oken/jensn as a bass that you might see in internet also very seldom time-aligned but it is excusable as the DIY-audio people are mostly Morons ...

At CES there were Viagra-junkie sized power cords everywhere for $5000. Around our room were $10k and $20k speakers that sounded like a wet jukebox. It was the land of delusion.Value per topology is one way to measure but let's instead start with a p...

Well, I think that you should first read about Romys Macondo speakers. There are several threads with his thoughts that should help you get away from the DIY approach that did not give you the results that you expected. You have experienced first han...

I think the problem starts when we short circuit the process. It is easy enough to sell "the Best" of anything and still get mediocre results. If we are looking for a modular approach to DSET/speaker, then the results are also best guess because ther...

Thanks for your comments Romy.
You should like this bit of news... I forgot to mention, these will be round-section horns...
And yes, they will be very heavy... Made from a metal armature and very thick, natural (hemp) fiber-reinforced, plaster...

I think the main idea, like you say, is to enjoy. For someone to take the time every day or even every week to sit down and relax a couple of hours and just listen to music, and close thier eyes and concentrate on Mozart or even Patricia Barber is ...

by someone who has experienced DIY background and basics how to „design sound“.
This is of course a precondition. Of course we can’t list a „kit“ here. If we

Silbatone made a Demo with those Horns (the big ones)They said, it is one of three existing WE Horns, made 1935/36 (only mod is the addition of the tweeter you can see there). One Horn is made for 3500 Visitors, so we got a 7000 People Demo with them...

For now I'm quite sure about one very important channel - 1200Hz+.
JBL2453 in 550Hz LeClech horn works perfectly for me!
For the lower channel 500-1200Hz I've tried the same driver JBL2453 in 350Hz Tractrix and result is not bad, but not pe...

I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; but I came to the concl...

Tax, do not go over yourself with “building paranoia”, looking for drivers, horns, boxes and etc. If you are looking for 80Hz to 200Hz range (you will need higher upper knee for AG Dou) then you do not need a bass driver with Resonance frequency of 3...

TH,Avoiding mistakes is something that we would like to do. It saves time and money BUT unfortunately the science of building loudspeakers is based on specs, not „Tone“ or „Sound“. Being an engineer can help make beautiful drawings but we all learn t...

I should not even stress more that I do not like people at DIYAudio.com. The domination majority of them incredible idiots and the brightest among them… do not really have any perspective what audio is all about. I do admit that in some seldom cases ...

hi Romy. Nice topic! I have a very nice memory. I started very young, supported by a friend who tought me a lot and gave me books to study. I learned the basic formulas and started DIY speakers from purely technical perspectives, graphs, math, calcul...
