Hi Greg,linkSearch the site and you'll find that Ulf has created a upper bass horn using the aforementioned TAD 1201's.I also own a pair still in boxes waiting for the weather to warm up enough for me to start some enclosures and horns for.My origina...

RomyThis topic is relevant to me currently as I am attempting to get a 750Hz low-pass into a valve (tube) amp that is driving a bass section ( Supravox 285GMF in an Onken cab ).I have run through a few options in my head but can see various problems....

Thank you, Romy, for input.
I'm still following my initial concept:
Bottom horn is finally ready and I like the sound with 12" Supravox in it. Moreover, I don't feel the need for Tapped Horn...

user="kodomo"]In my first design, I kept them all in a vertical line.
It had one channel less back then. When I added the 1" throat JMLC 1000, I
decided, as the tweeter operates over 9.6k, the slight misalignment may not
matter. Still, I k...

Hi Romy,
I think my post is a little confusing.
The picture shows all the different drivers
used in these experiments. The Altec in
wood
horn is the constant with the
the 21" bass channel. Then I bridged the ...

I read your comments re: the PT-R9.
I have a pair which also measure about 9 dB below my Supravox 200 EXC drivers in sensitivity using the Earthworks measuring mike on the DEQX unit. They do sound very nice, however.
Also, I find this site to ...

user="Murataltuev"] So, driver for 1200hz down is under
consideration.I'm going to try 2453, 2451, 2490 and Supravox 12" for this

12" Supravox for the 300-1200hz range.A...

I have been searching for a good discussion on this subject for a while an yet to come across anything that really explained this: What are the causes/factors of compressed sound? I know it when I hear it, and have heard this phenomenon attributed to...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

Hi,[quote user="morricab"]no mention by the manufacturer what brand of autoformers are in use (or if they roll their own). [/quote]
There is one thing I can say. Nickel Lams are bright, shiny and light coloured. Steel lams are dark and dull. I...

Looking at the pictures of CES I came across a new Seoul-based company Silbatone Acoustics that show off a new speaker “APORIA” in Vegas. It is a back-loaded Manger.
What I read the company philosophy I was not pleased.

Kids, do not let kids to subscribe the popular audio-freakish myths of the records spinning people about “the extraordinary beauty” of the Denon cartridges. Yes, the myth has some reasons: many more expensive cartridges are bad, very bad for th...

[quote user="morricab"] It is a good question that I also asked when I saw this speaker. Afterall, everything being equal using the same materials for the drivers is more optimal from a coloration standpoint. My guess is cost. They ...

[quote user="Romy the Cat"]Well, I would advise you do not order any horns with aiming 2490.
Get the drivers first and order the horns AFTER you feel that the driver
satisfy you. The fact that the loaded driver can hit 300Hz does not mean a lot.
Y...

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...

[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.

[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

I would like to share my 5-way horn project.
The idea was to have full range system, so the first horn built was Tapped Horn.
I got design from Volvotreter.de and was really impressed with performance of this monster.

Thanks Romy,
I would have thanked you sooner but I had the day OFF of my day job today and had no time to post until now.

I had a feeling there was no easy answer, wasn't sure if I was missing something, had scoured posts for a whi...

Kodomo,
A brief post about concerns. Feel free to discard it.
LF modules – are you sure that you want to go with ported
solution? You can model your boxes and use any good drivers but sonically with
port you will end up with bass that would h...

Thanks, Romy, for your generous reply.
I won't try to address everything about everything, but let me bore
you with a mini-history of what is going on with my playback so you
will understand where I'm coming from and where I'm trying to ...
