hey jessie-I've wondered the same thing-- and the more i end up twiddling around with it, the more I think it really either comes down to good measurements, or good listening! And in fact.. probably both in conjunction!I have a small 2 wa...

Daniel, if you have start, the igniting voltage, on the gas tubes 197V then it is perfect. If the tubes do maintain stable 150C then leave it as it. Each of the gas tribes has own stabilization voltage. If one of them has let say 148V and another 150...

Watched youtube feeds and found my way back here. Interested to hear more about your priorities in the new build. Given the project is inspired by Dunlavy, I presume the build will be time aligned with first order crossover? If so, are you intendi...

Ok, I am again confused with the terminology. You seem to relate reflections (indirect sound) to orders of distortion. That is, 2nd order distortion has something to do with the first reflection of sound. I see these events as indep...

I have no doubts that it will work but I would like to understand HOW it works.
The objective it to have first order filter, of cause not the filter where capacitance do high-pass roll off but RL. In RL filter there is not reactive elements i...

Spent today a whole day moving the boxes, do some measurements,
fighting with REW interface, thinking, some listening… Found some bugs in the
system that I think screwed my initial feeling. The bugs were mostly by Thomas

It is a RAAL Lazy Ribbon with the integrated transformer doubling as DSET OPT. Surprisingly, I started with a 4th order high pass filter which has steadily migrated back to first order...and it works.Next step is to trial a biradial horn for a bit m...

Recently, I was fortunate enough to have an extended listening session with the Living Voice Vox Olympian outside of a show environment. Since said listening session took place upon a boat – moreover, a wooden-bodied boat – under what can only be sai...

Hi Romy,If you have a moment between setting up your gear in new room, can you point me to the thread where you discuss suggested wood horn finishing techniques? I can't find it.I am hopefully on verge of placing order for my first mid-bass horn for ...

Tweeters are a real mistery. Some should sound great and they dont, and some never will.I think you do need a lot of dynamics even at 10khz in order to get those sparkling highs that really jump out like the real cymbals and other crashing metals! O...

I know many would view the two frequencies as similar and perhaps of little consequence, but I have my reasons.My primary, driving objective for wanting the horn to produce sound faithfully to at least 90Hz is that 90Hz represents an ideal crossover ...

I really do not what is gong on there and why. Thorsten's comment that line-level crossovers do not act like speakers’ level crossover confirms what I feel and what some other people suggested me. Yes, the reactance of the crossover component, the in...

the Vandersteen 7 remains the most satisfying cone speakers in mybook for the past few years. It does not sound like a typical first order speaker. Richard got it right somehow and no its not the 11band bass eq that does the tricks....

Hi Romy, I imagine the coupling cap in the full range melq acts as a first order high pass filter: is there any reason why one could not lower its value to raise the cutoff to a level one would otherwise redundantly need a speaker-level filter to ach...

OK, here is an easy homework: how to randomize elections flow but do not create microscopic? The answer is actually contains in the question. The answer is one of the solutions that my first thing that I will be trying sometimes. The second solutio...

Romy, would you explain / help me better understand how you implemented the HP filter in Melquiades?The schematic shows a series cap after the first tube stage (C3 and C4 in the schematic). I think these are the first-order HP filters, correct?Quest...

The coupling capacitor is a first order high pass filter. I have .68 in there for there for this purpose. Obviously the slope will be shallow, so precision in the value will not be critical....

I own a pair of the Total VictoryIII that pair nicely with my room due to the inside firing woofer (tames my room nodes). The marketing of the products uses tremendous hyperbole (words like 'breakthrough' appear often with regard to speakers, c...

Zako, the first order of business is programming; ie, what sort of music could you enjoy, best case? In my own situation, the quality of the tuner is the least of my problems!I am getting to the point where I wonder if computer-sourced program might...

Interesting experience - thanks for sharing.Just yesterday I posted about this topic:http://goodsoundclub.com/Forums/ShowPost.aspx?postID=13892#13892I will first use a 6dB/octave crossover, but may need to go to a higher order slope instead. I'm cro...

Here is the list of the thing to do with Vitavox S2 in order to use it in 4-ways installations. The S2 must not be used in 2, 3 ways systems. It possible to do with S2 whatever you wish but pretty much any other way to utilize them produces some very...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

the bad result during audio show does not mean anything, only good results
count. You see, there are zillion reason why during the show the sound might be
horrible. The inadequacy of the people ...

It's still first order since you have more than two octaves overlap.
But it's a two pole quasi first order as well. I use this trick
sometimes. The problem with first order is that excursion continues to
rise below the crossover point, which of co...

Dominic,
I personally do not believe into nether non-powered preamps nor into autoformers volume controls. In my world as soon a any voltage dropper begin to drive any cable it calls trouble. A volume radiating voltage divider or transformer should ...
