[quote user="kodomo"]I dont think a standart klipschorn would satisfy the cat. I had one, then I heavily modified it and in the end I built my full scale horn system. I still keep that modded khorn system as a second system.If I may suggest, if you u...

i do it and i did it, but as a newcomer you have to sort out all the infos...not that easy!
[quote user="Romy the Cat"](This is normal, I have written about it many times. Those large bass drivers have a lot of inductance in Voice Coil, the inductan...

At first I plan to power the thing SET, with a known, existing amp (a triode wired EL84) which I've already built and know the Sound. It is not bad, but a little "warm" sounding (second harmonics, and is low powered for low frequenci...

That is one textbook HF ribbon, Romy, long, narrow and naked as a jaybird.Don't be surprised if eventually a certain amount of magnetic "dust" somehow finds its way into that ultra-strong magnet gap. Who knows what it is or where it c...

It is very easy to figure out acoustically. Feed the drivers and their crossover with a reference tone of fixed amplitude and fixed frequency, roughly in the middle of crossover point. Disconnect one of the drivers and measure the acoustic pressure e...

I already have some PY500 (it's a sign =))) ) and I have 836 too.I read about Malquiade amplifier threads.So it seem peoples on this forum like horn speakers (I love them too) and are looking for fast transient response, it's exactly what I like.But ...

[quote user="MINGSU"] SG505TT + S150 horn crossover at 180 Hz is not recommended by GOTO. The SG505TT driver is not recommended to use with single throat S150 horn. Double SG505TT driver is recommended to use with single...

Hi all, I have a t350 horn that I recently got out of an old cabinet at a junk shop which does not work. If I connect it to my Marantz 1030 amp it will only play very faintly as if you are listening to cheap earphones laying on...

For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably no...

Hi! I wanted actually to get rid of the behringer. Because I have only 1 super high quality tube amplifier and it was difficult to marry different amps with the speakers. And you cant use a high quality dac with the active crossover. I ll right now ...

Romy,I am in agreement with your observations. I am not certain I will end up using specific crossover slope, like 6db or whatever. It's what I prefer in my current setup. I will try to have make a design that will work with this type of crossover --...
|
|
what a great idea-- i never really thought of a sort of 'low pass bypass' inductor of sorts?! i'd always assumed that inductance was similar to capacitance in that regard-- the more you add, the more you get-- but hadn't thought about the...
|
|
After much listening and measuring I convinced myself that there is no way for me to escape the use of the 24dB per octave slope if I want to keep the sound of my midbass horn not violated. I also have to admit that I will not be able to render 4th ...
|
|
Since I change the transformer I picked some harmonics and now I feel that my midbass has a bit too long roll off. I moved the second low pass filter close to the first filter. After a very careful listening and some thinking I ended up with setting ...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...

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...

First off, I forgot to mention an interesting observation: Before running the sweeps (previous post), since the drivers in the upper-bass horns are new, I decided to verify/optimize rear chamber volume (they are easily adjustable)... I wasn't expecti...

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 ...

|
These are very interesting effects, all right. No way to be sure, I supppose, but if I understand you correctly this could be related to what I was calling the "MF attack" phenomenon, up the page. Although the ai...

hi romyi am listening now abought 2 weeks my orphean horns. when they arrived, i first connect them to my electronic crossover, and they sound horny, very bad. after i connect them to the own crossover, sound changed right away. now, that i heard mos...

Unbelievable idiot! Last night an audio guy visited me and I played to him some music. I was not sitting in the listening spot but what stroked me was now stringent and how shallow the playback sounded. I was waling around the listening room, scratch...

Guest napping now from 16 hrs jet lag, so I have a moment...Jorge, you raise an interesting point about THs. I may be incorrect in assuming THs sound worse as they play higher in freq. Perhaps instead the limitation is one of narrow bandwidth rathe...

[quote user="gurevise"]Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Bala...

Ronny, it does sound interesting, thanks. As they said they were the people who supplied the Red Rose Music speakers with Ribbons? Still, while they called a statement” "Ribbons are excellent but suffer from bad efficiency" as an warranted myth they ...

Luc,
I am not ‘lucfm’ and I hope he will reply to you but I would like to pass some of my observation that you might find useful.
In my past when I discovered Fane Studio 8M I went over a number of 5-8 inches. At that time I used AG’s Trio upperb...

I am not completely thrilled with TwoGoodEars new crossover.

First of all , Stephano has a preamp with tube out stage. The guy in his post says that the l...

I think this is an interesting topic. I have made experiments (with a digital dsp processor) in my system and tried 4th order crossovers. I did not like the sound at all. Trying to explain this sound signature is tricky but here is my interpretation ...

It was not so long ago that the Super Milq was a twinkle in Romy's eye,and now it has come to the point he is a strong proponent of DSET (not to be confused with DH-SET). I am always a big believer in the power of topology. I was thinking about...

If you know how in some optical systems imagery get destroyed when an aperture getting closed to F64 or even smaller, then you understand what happens in compression driver when frequency get higher and spaces smaller. Yes, the proximity of wavelengt...

Interesting topic. Anyone going the digital x-over route should keep in mind that if you just put a digital x-over into an existing system you are going to be disapointed, and I don't care what brand crossover you are using. You have to get the level...
