"When I moved my system
and was just learning the new room and making changes, I was also
listening to more Bach than usual. I mostly wanted to play Partitas,
Inventions, Preludes, and Goldberg Variations. I was tu...

My feeling about perfect listening chair has altered lately – I need another sit at my listening chair, so it kind of becoming a listening couch instead of listening chair. As much efforts I spent to explain to my girlfriend about time alignment and ...

[quote user="RF at Ona"] Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers...

Romy,
Funny stuff... especially the the AN piece. Equally surprised octopodes ? Brilliant !
As for the Bruce Edgar post ? Not as funny. And it's off base.
The Titan II system has a straight axis upper bass horn instead of a folded upper bas...

Doug, it is a lot of tuner went over your hand. I wonder what drove you to do so. Was any specific quality of sound that you were looking and the tuner that you own did not serve you?

Romy, Here are some images of a slight variant of your Macondo Frame proposal.
This version has the Fundamentals horn more rigidly coupled (this may or may not be desirable) and does not require a counter weight. It may also be a little more co...

These days I am traveling frequently and relegated to listening to music via headphones and "portable" sources. I will briefly post my brief journey as a personal log. It might provide a starting point for those who might find themselves in the same ...

It wound up taking 9 weeks to get my re-built cartridge back from/through the Ortofon DK/USA consortium, and then I let the re-built cartridge just sit there in is box for another 2 weeks. When I finally went to re-mount it, I managed to snap a ver...

A few days back I visited an audio person who demonstrated to me his experiments with extreme lateral deviation of souses. Regardless if I agree or not what he was doing or trying to do the demonstration has an unexpected result. One day I was driv...

[quote user="twogoodears"] I learned nonetheless to use for my (limited) task (fine tuning my speakers and audio system in my music room) the great IVIE IE-30 R.T.A. and IVIE IE-20 white/pink noise generator [/quote]
You do not need white/pink...

I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

[quote]might I ask why[/quote]1.)the bass will be pretty coloured...mouth not large enough for proper bass response..

[quote user="pe1mmk"]Well Cat you can call me whatever you like, but you still did not answer my question. Both have a horn for highs, for mids and for lows, only the sub lows are handled differently. [/quote]

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

[quote user="Jeffrey Jackson"] so a few things... one, there is a pair of Goto 370 on eBay and pictures of insides... the newer ones are made the same, but it seems that the execution has gotten a better/cleaner compared to these.. my diaphragms look...

thanks I have a few questions to ask if you do not mind:
1) Did you experiment with surface of the horns and a negative contribution of smooth surface to Sound?Smooth surface are fine don't waste my time on a trival matters.

[quote user="Serge"] Wouldn't you want to try some HF diffusing stuff on your back wall windows? Like wooden plank blinds if you see what I mean? Or you want the reflections to be catched earlier, behind the listening couch?[/quote]

Spend a good few hour moving the boxes, connecting the cables
and do other sort of things. Was looking for elegance and more symmetry. The
objective was to put midbass channel between the main horn islands and set the
horns, the midbass and LF in ...

My 18-cell is a classic 18-cell very similar of the one that the guy from Sweden built:

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 be possible to run guy wire...

Yes, the crossover looks fancy :) More than that it does the job. The vacuum caps are only for the tweeter and the upper-mid beryllium. Still they are bridged with micas as they wont do much alone. Adding vacuum caps smoothens the transitions and sou...

Coops, I less care about the attacks on me, I know that I am a pH-indicator of Moronity among audio freaks. So, if some specific idiots out there are not happy about me then… it is good for me. The higher we climb in mountains the stronger wind and l...

I picked recently a pair of S3 drivers. Not that I need them but it was good deal – perhaps someone in UK have demolished an old movie theater and a large school of S3 drivers with original diaphragms hit the maket recently. Also, I always meant to t...
