Ronnie,I do not know any. But the major question is why such a crossover is necessary. Obviously it requires 3 amplifiers and if so then the filters might be built in the amps. It one needs it for system prototyping purpose then if is fine but the de...

[quote user="Markus"]Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that.
I would love to use ho...

I am observing an interesting and surprising fact – I am begging to like my active Marchand crossover. I did a number of modifications to it and it looks like the parts are broken-in now – it does sound very pleasant for my ULF. I feel it is a bit to...

Hi! I wanted actually to get rid of the behringer. Because I have only 1 super high quality tube amplifier and it was difficult to marry different amps with the speakers. And you cant use a high quality dac with the active crossover. I ll right now ...

My sub-bass amp is back but I am not sure if I am comfortable with it. The guy from QAudio did a wonderful job to fix my modified B-2 power amp and now I have my amp for ULF with passive line level filter in it. So, Now I have two identical, fully fu...

Yes. For prototyping.I found out that Luxman built an 8-tube unit exactly like it.I borrowed a picture from the net: www.webbtjanst.se/temp/2003.jpeHowever I think it might be interesting to build one, with decent pots, 6dB filters and 6 buffers afte...

Thanks for your comments, Roman.You're someway right... Goto foolishness;-))) maybe... also Mingsu wrote he "never" saw such a (Keith's - or mine) way to use S-150 mid-low horn... everyone's - me too, also with some doubt - copycatting each othe...

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,My current active crossover is a DSP unit which likely has low enough input impedance and single ended inputs. I added BAL inputs by using input transformers. By no means do I want to use this combination as a representation of my crossover! I i...

[quote user="Kcct82"] I know you're not a big fan of digital delay, but I'm using behringer DCX 2496 to make things easier... this way I get to keep all horn mouths on the same plane which avoids some reflections (from other horn mouths). [/quote]

For a casual observer it might appear that I am constantly fought with my ULF, finding and loosing better and worse configurations. It might be so but I have a very strong sense of objective of what I would like to accomplish. I want to reinstat...

Jessie, in the configurations of the horns and derivers that you are building your mid channels do not exposed too much to stresses. It is not that you have a situation when 1/4 octave more and less will send your channels into suffocation - your hor...

I was reading the Stefano Bertoncello's post about his new multi-amping again options.

.. and I feel that it would be a good idea to brief summarize multi-amping cros...

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...

I just came back from Stereophile Show in NYC. A couple of observations. Haniwa's FPIC-100 DSP seems to be nothing but a typical DSP with digital crossover/equalizer/delay with auto feedback through a microphone set at the liste...

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...

I had in my basement Marchand X26 crossover that I use over 10 years back. Since my B-2 power amp with passive filter is being fixed I setup the stock fixed B-2 with external Marchand active crossover. I spent some time to modify the Marchand X26 bi...

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...

SG505TT + S150 horn crossover at 180 Hz is not recommended by GOTO. The SG505TT driver is not recommended to use with single throat S150 horn. Double SG505TT driver is recommended to use with single throat S150 horn.&nb...

GOTO always recommend to use 1st order active crossover and 2nd order passive crossover. The reason to use 2nd order for passive crossover is to protect the driver. Of course, the user can use whatever they like the best but the recommendation ...

Romy,If you look behind the physical time alignment and start discussion about relative time alignment, that is a good start. Thing puzzle me about your view and comment of GOTO system setup that you have seen on pictures or web. How will you know ...

If you are going to build such a huge cabinet or put a hole in the floor to use the basement as a chamber, why not just build horns in the basement with a straight 8-10 foot section in the basement with the back chamber resting on the floor, cut...

I dont think a standart klipschorn would satisfy the cat. I had one, then I heavily modified it and in the end I built my full scale horn system. I still keep that modded khorn system as a second system.If I may suggest, if you use klipschorn, you ca...

Hello,I just logged myself in so first of all: Hi Everybody ;)Few days ago I aquired a pair of very interesting 3way horn speakers which seem, as I imagine, to ba an ambitious DIY project from the past. These are basically the Altec Vott A7 replicas ...

They build the DAC, patented the clock... ok.
They build their own preamp. Fully descrete class-a balanced,
john curl wouldnt do it differently. Nice. Low and adjustable gain - very nice.
