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, ...

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...

[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...

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...

scooter, that was a whole point – to see if the fundamental dilemma of the those designs was addressed. Frankly I was prepared to see some kind of interpretation of unity horn, not just blunt lock of any efforts in this direction. As is, the Vittora...

Have you use GOTO dirver before? Have you try it with the "GOTO" recommendation? Have you listen to GOTO in your own system? If not, I suggest that you do it 1st and then draw your own opinons then. GOTO never said don't worry about alignment. T...

Hi Romy,
In this picture it looks that attic opening's distance to listening position is very close to distance of chair to the main speakers. Time alignment?
?

Was invited over to Romy's today for a listen. In the last two days, he made several small but critical changes in the time alignment, crossovers, and room damping, and the sum of them has brought his system up by several notches producing the best a...

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...

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...

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...

[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 ...

[quote user="Romy the Cat"]That is my constant dilemma while
I socializing with audio people. Om a surface the question about T/S parameters for Goto is reasonable.
It means now I need to correlate whoever I know Goto user and the people who
know ...

I've been thinking about this matter for a while but could not find a better excuse to formulate my theory then in this topic. My simple theory is that if we reduce our concept of "music" the more fundamental concept of "sound" as point of reference ...

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...

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...

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:

Hi there
I can see Romy's face when he's trying to figure out Martin's time alignment strategy;0) I have Martin's 204 Hz horn with Fostex 208 E Sig. These horns are to be big to properly integrate with anything. They are OK with Fostex Lowther drive...

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...

Last night it was a surreal experience, sort of QSound–type experience. I still do not know here will be the exact location of my listening chair, it is debating with 2 feet, and because of this I did not bother to lock the Macondo’s channels in tim...
