[quote user="Axel"] I hope I got this right when going through this long thread with LOTS of information. Did you mention for upper-bass cross-overs Elko’s (electrolytic) only to be your preference? If I have it right, any special preference at a...

Hi
Good news if the analogue stages of the DCX2496 is so bad.
So the improvement of a modified unit should be worth the ekstra work,
and remove some of the x-overs negative influence on the sound.
Which is always good to know beforehand.
Th...

Digital Crossovers are wonderful. They are wonderful because they might help to very easy to learn if you are not a Moron ™. I have covered this subject in the threads:
Dream Hi-Eff Speakers for an “inmate” and in Horns and digital crossovers.Still...

Of course most of the people do prototyping the type of crossover they need for a given channel using active crossovers. As the crossover point, slop and in some cases Q are found then the same data is applied to a given topology of line level in-de...

Well, I never felt that for prototyping I need more then one-channels crossover as by use of the poor sounding prototyping crossovers I never look at the system in it’s entirely but rather for the “technical listing” of just two channels that I...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

I certainly DO NOT state that anyone who advocates use of digital crossovers is an idiot but I do observe a very interesting pattern. There are a large number of people among Internat High-End Audio whom I do know and who are perfectly qualified to b...

[quote user="Gregm"]Coming back to the "multi-driver" spkrs -- especially unfamiliar ones. It has taken me a long time to "optimise" the positioning of a pair of 4-way spkrs (9 drive-units, of which two in the back, in phase)

Yes, T, I understand it all. However, returning back to the subject, I would like the message be stressed: I feel that if people seriously contemplating the digital crossovers then they fight wrong fight for the wrong reasons. Do you remember the jok...

Hi Romy,I am curious as to why you object to the use of digital crossovers. Is it solely due to the ADC for analog sources? Assuming that digital is the sole source, would you still conceptually object and why? I realize you probably have touched...

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...

I was listening last night the HF section of MiniMe. It was interesting and frankly very promising. The RAAL 70-20XR were fine and he JBL5 did splendid. They are not properly integrated, were not measured and were made up to work together well, it wa...

[quote user="Romy the Cat"]I think it takes around 60 seconds on my amps. I have 2 minutes delay for high voltage, so it all within the limit. [/quote]
That is good to know Romy. It was quite frustrating when I tho...

[quote user="Romy the Cat"] Even if it is possible with a given (multichannel, faulty design) loudspeaker then the DPLOS become very fragile and appears/appears too sudden, without a gradual improvement while approaching the DPLOS. The keys are phase...

Nice posts Romy and Jan, agree almost 100%. I've heard the Behringer in an originally crummy system and it butchered things completely. The input levels were low, which as you point out, won't have helped at all.On a vaguely related note: I dunno if ...

I am very interested in your DSET adventure, and is trying to learn more about the application of adding crossover elements into SET amps. Looking at the schematic, I noted that you add first-order passive filters before the first stage of your...

Is there any abstract value to going for a preamp with a stronger output if you're using a passive xo at line level?I'd prefer to answer this question myself but i really don't have the budget to be swapping amps.How does a PLLXO interact with a non-...

Markus,
If it is your task to stay with a single amp then all bids about line-level crossover are off. I would like to stress that although there are zillion theoretical and applied reasons to prefer line-level but still it does not mean that regula...

I ask Jeffery about crossovers... Yes, the GOTO sub comes with a steep slope. The crossovers Jeffery built (all the horns) are 1st order, and cross-over points fine tuned by ear.
The “what to do different or the same” question was...

Interesting topic. Anyone going the digital x-over route should keep in mind that if you just put a digital x-over into an existing system you are going to be disapointed, and I don't care what brand crossover you are using. You have to get the level...

The electrolytic capacitors in the woofer low pass circuit are certainly dead. They look perfectly normal when old, just lose capacity in a serious way. The NS1000 had ferrite magnets that don't need remagnetization....

I think this is an interesting topic. I have made experiments (with a digital dsp processor) in my system and tried 4th order crossovers. I did not like the sound at all. Trying to explain this sound signature is tricky but here is my interpretation ...

Very interesting read. I like comfy!Now for ultimate comfiness: would you recommend an actual unit for prototyping?...A digital crossover that works OK, with >=2 analog unbalanced inputs and outputs, 2*3 channels output, possible 6db slopes a...

The line level crossovers have some advantaged: they loaded into higher impedance and therefore the values of caps are smaller. Also the line level crossovers loaded against fix impedance, contrary to the speaker level and this allow writing a very e...

My own experience suggests that it is possible to do speaker-level passive crossovers, but I must qualify that by saying that although I have put a lot into the crossovers themselves, and the wire,etc., etc., it has only been since I got the ML2...

[quote user="Kerry Brown"]I don't understand when you say active crossovers don't attenuate. Mine does. Very well too, I can trim channels to match each other perfectly. And DEQX volume control is 'analog' = step ladder resistors. [/quote] I am not...
