What you guys are missing is a grand scale of the concept. You are talking about voltages, implementation, electric chairs and the rest of irrelevant crap but I am talking about the pure inspiration from the concept. No one runs to solder anything. I...

its still expensive, but birch-plywood is not that much cheaper. its around 30-40 €/sqm. the only experience i have with a carbon-foam composite is from making a skateboard for my gf´s son. looks very good, but whats more important, ab...

Hi Jessie:It is indeed a (t)horny dilemna whether to get rid of the midbass horns now, with a view to starting all over again and customise the new horns for your eventual new home in Detroit or ship them at unfortunately what will be a very substant...

[quote user="skushino"]ScottL,It looks like the two pics you posted are of different systems, the first being slot loaded PP, and the second (full-system) showing a "traditional" IB. You also seem to be confirming my intuitive hunch of potential sou...

It is so funny. As Kitty and I are looking for different
houses we look at different listening rooms and we have different ways to think
about room sizes. She think about space for her piano and size of oriental ran
she would drop on the floor. Wh...

Dear Romy,OK, some more about the midbass.Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than w...

Devo, the GM-100 for sure is a good triode to get 160 watts
output power in A1. Still, it would be a good chose, from my point of view,
ONLY from a prospect of embracing as good DIY audio project. There is nothing wrong
then to do the good DIY aud...

There are few more observations I would like to share after listening
my new IB over this weekend.
The midbass. The midbass channel that is handled by a single
Vitavox 15 driver with use of my new IB became if not more propitiate but at
least m...

2011 will be a busy audio year for me. I will have a nice large space 28 feet x 20 feet x 11 feet which I am free to modify for audio. The walls are 150 years old irregular stone the floor is cement and the ceiling is composed of structural...

Referencing the post from my “Playback Listing” forum:

This year is the first winter that I live with this new listening room. Last winter the playback was up and I still was playing with minor arrangements of my ULF channels, cable and a few other things. For many months I do pretty much nothing with my...

There is a fusion in contemporary turntables: to make platters and tonearm bases separated. I am not an expert but in my ignorant common sense I do not think I like it. For instants take a look at a German table:

Good question, rowuk, particularly by the fact that you are
looking a way not how to get it but to understand the ways to get there. Also,
I am very glad that you are not taking about “slam music” but about, where good
bass certainly shine but abo...

I think 8-8-1 will be very good configuration all together.
Make sure it stays sufficiently far from back wall. Point the axis toward to your shoulder and I think it would
be fine setting. Turn off tweeters and Fundamentals channel and set right

SG-146LD in 46horn 50-400Hz
I've added 0,7m length to 2m horn, so now my
mid-bass horn has 4" throat and 1x1m mouth and 2.7m length. [/quote]

This week I will be trying to address why the Milq midbass is clipping. This is very interesting one. Currently the Melquiades LF channel uses an output transformer 700R to 5R or 11.83 to 1. I thought before that I have much lower ratio, like 5:1 bu...

[quote user="drdna"]Since both sides use different amplifiers, I think there may be incomplete correlation between the two sides in terms of coincidence of frequency response. Small changes in frequency response that vary with frequency and ampli...

I've continued thinking about construction since posting my previous laser-cut hallucination (titled "Painless mid-bass horn"...). Thinking mostly about the transition from round driver to rectangular horn... I don't know how...

[quote user="haralanov"] The horns, even the fast opening ones are physically too deep for their mouth’s size, and this leads to a psychoacoustic illusion that the sound images are arrested at the bottom of the horn and from there they scream they wa...

[quote user="Romy the Cat"] I guess your definition of “doing something different” would imply reading of 534 pages of BS from people who have no idea about Sound about advantages of LA-horn over tractrix… [/quote]Touché! Now you are referring to my ...

Dear Malinowski,
Here are the input data used in the HornResp simulation for the tractrix midbass.This is a 117cm long tractrix horn with the TD-1201. Throat area 84 cm2, mouth 10000cm2 with 5,6 liters back cavity.Ang: 1Pi; FTA 89,80; S1 84;...

Ok, you are getting somewhere. I am not sure why I used the 100R, 50R and 22R resistors. It is good idea in some cased to list the potential of some circuits but it need to be used ONLY what it necessary. Do not forget that in your case you have 5 ch...

[quote user="Murataltuev"] Now it is
clear! Thank you, Romy!Today I auditioned and measured GOTO with closed hole in
back chamber. Mid-bass completely disappeared!
With closed back chamber it works efficiently
only from 200Hz! So, I'm going to tr...

Hi Paul,
The L.Cao are quite nice fullrange drivers at a reasonable price. Compared to Lowther EX the L.Cao lacks some dynamics but have a better tone and are more homogeneous. I am no fan of whizzer cones. To use it as a midrang...

I think if you use Pure Power 3000+ it is better to use shorter power cables (2m is very good) . the bass and attacks are better with shorter Power cables.
you should not have any ground loop in your system if you use Pure P...

Thank you Clark for your comment.Unfortunately, I think that you missed the point. It is possible that a power cord can change things. The description „better“ is a moving target however. Let us take for example a „full range“ driver in a backloaded ...

There is nothing shaking
in here. The roof structure and the things in the attic looks very stable, no foreign
sounds. There is no pressure attack, something that I was afraid. I am a bit
surprised how flat the ULF response I got. It might be the ...

Last week PurePower send me back my “upgraded” PP2000 unit that eventual get right sound. I did test it running my entire playback from it and found it usable. I found that there was VERY minor difference in sound between them, so minor that I w...
