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="msaudio"]When you set in your chair looking and listening 2 your sound system you are trying to create in your mind and your ears the illusion of instruments placement on the stage in front of you, to make it more lifelike and real. So y...

Angelo,Although the idea might be looks like an “elegant” at a hi-fi shows but unfortunately it has a lot of pitfalls, the terminal pitfalls for my point of view. This is only my opinion but still:1) LF channel- the bassmaxx. I never had or hear...

Hi Romy
a good sound in a room does not depend only on the speaker chain, but essencially also of the room acoustics. Probably many of the Trio systems didn’t sound right just because of that…. I was at Holgers Home in Lautersbach back in 94. He ha...

My idea is a upright horn like your "midbass hanging thing", at 200 hz for the smaller size of it, and this will be my work for 2009/10. What I would like is exponential curve, not tractrix horn, something like this one...

I went to THE Show again this year, along with a couple of audio friends. This year I was better prepared, with preconceived notions about what I wanted to see/hear, and where to find that gear. I did not try to “cover” the show, at all. I just wa...

Thanks for your advice Romy and Stefano.I have used RTA with condenser mic in my past systems but I admit I am no professional at it. But I am not clueless with it either.. In my previous setup when I was playing with open baffle designed speakers, ...

[quote user="drdna"] Fundamentally I think the injection channel and layered sound are different things. The injection channel is designed simply to compensate for the timbral shortcomings of a particular driver. However, because of lobin...

Some thinking about Romy's Injection Channel (see the following thread) : GoodSoundClub - Romy the Cat's Audio Site - The "Macondo Ultimate" MK-XXVII, Revision 432 ... brings me to a question that I've had a for quite some time: When aligning a "norm...

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...

[quote user="Romy the Cat"]Herman, I completely do not understand what you ask. The physical aligning of magnets is absolutely irrelevant. The crossover slopes are irrelevant. [/quote]OK.[quote user="Romy the Cat"]Why would you need to do switching b...

I am not a huge fun of S3 for MF use as the ceramic magnet is less interesting then alnico magnet for HF applications. For the low mid, or as I call it the Fundamental Channels the HF problem that ceramic has do not manifest themselves. My Fundamenta...

Moreart Most people on this site only badmouth things they don't understand. From what i have read the last few years on romy's site, there is a leader and a bunch of follower's that have no clue of audio basic's in sound reproduction. The leader j...

My experiment with midbass channel last week was wonderful
in a wild position. It proved that I have enough gain to drive my current bass tower
from Milq. Also, it proved that using a small midbass in wild position and playing
with crossovers I ca...

Well, I'll stick my neck out and tell you what I think. I would say that it sounds right now that you have a kind of undefined idea of how you understand the sounds of audio reproduction. Sort of on the level that you know that you like s...

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...

Hi Jorge, Thank you for the response. Re: cable, yes I've been too lazy to install binding posts in the back of the cabinet. I have no good reason, necessarily why I am crossing the 250 Hz horn at 1k. I posted my measurement above, but of course this...

[quote user="jessie.dazzle"]Assuming situation 2 is possible, receiving mid-bass primarily as reflected sound, one would have to take into account the reflected path of that sound, and how it describes the mid-bass part of the image, relative to the ...

The mini skirt analogy is a great fit. That is my experience.Or maybe like that stunning girl has small breasts and one has know the joy of a good handful. There are ways for enhancement and while one could get more, the girl is no more beautiful and...

You might think I'd learn by now, but over the last two days I have traced sonic problems to the following: Dirty pins on one of the tubes in my phono stage; Loose counterweight set screw/too-heavy VTF; Loose cartridge mounting screw/...

[quote user="Romy the Cat"]Jorge, your comment about
the physical instability of the pipe stack is well taken. I think if it is gone
from metal then it is possible to make it steady. In the way how Antony want to
do the pipe feet I think it might ...

Here is the next more accurate and less abstract version of the new amps input section. The different functioning resistors are not equated to a common denominator bit it is how it will be build initially, during the calibration and testing and I do ...

Hi Guy, The Oracle seems like a nice solution - I saw you write up on Peter Empson's forum. They seem compact enough for my requirements. How do you handle time-alignment with the mid-range? Or is this not a problem? To be honest with you I'm not exp...

A correction: the installation above is not Reinhard’s but by Klaus Speth. Klaus and Reinhard experiment with audio together and Reinhard has his own Goto setup. Here is more information about Klaus’ system with Reinhard’s comments:

Of course the issue here is not so much time alignment as it is whether the physical structure will allow/facilitate decent LF. And of course "framed" structures eat some LF and create a +/- unpredictable LF environment.Two of many questions are, wh...
