Hi Keith,Interesting experience you have as I have found running my 505TT with the 160hz le'clech horns between 320hz-1200hz (with first order slope) works best for my setup and using my 15" goto sg-38wn woofer to play under 320hz (which sounds very ...

[quote user="noviygera"] I want to listen to both 12db/octave and 6db/octave passive versions and see which one sounds better. And keep the one that sounds better. [/quote]Herman,
It depends what you would like to listen. If you would like to ...

I read about Klaus Speth crossing at 6k6 and looking at the graph it seems like the absolut wrong thing to do. My first thought would be to cross at 5k first order and make use of the rolloff there. I'll have time over the weekend to hook them up to ...

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...

Hello Haralanov,It is hard to talk about sound, and define points: this is why the post is so long.Most systems I have lisitened to that measure a flat response have exagerated high frequencies and usually the midbass is a little shy, this might be ...

Keith could you clarify? The TD 4001 has 1st order acoustic slope below 1khz when mounted on most horns. So adding a 1st order electrical slope to that surely does not make a textbook 1st order crossover.
If the 1601a is being run first order abov...

[quote user="Paul S"] As a certified non-expert I wonder about 1st order XO with the tweeter, because of the phase issue. Probably stupid, but I always figured that at 180 degrees you could just switch the wires... Do I remember reading somewhe...

Hi all,In my experience it is VERY hard to get anything resembling realistic bass from a vented box, particularly with a Q of around 0.9 or 1. There is too much stored energy in the system and too much overhang. The best bass I have heard...

In my case I found that RAAL ribbon with first order can not deal with dynamics of S2 driver. [/quote]I suspect that my RAAL Lazy Ribbon does not have as much lower frequency output as your RAAL Waterdrop. RAAL refused...

I would like to think a little about the monitors. A monitor is kind of bogus name but useful. I usually call a loudspeaker that is not floor standing as a monitor. Sometime they called bookshelf but I hardly image any loudspeaker on a bookshelf…

Since I change the transformer I picked some harmonics and now I feel that my midbass has a bit too long roll off. I moved the second low pass filter close to the first filter. After a very careful listening and some thinking I ended up with setting ...

Too soon to begin in-depth descriptions, but after a good deal more work (and expense...) than I'd bargained for, it did not blow up, and there was not the all-too-usual painful silence in lieu of the first expected sounds. I admit I was as surprise...

Hi Jorge, Thank you for the response. Re: cable, yes I've been too lazy to install binding posts in the back of the cabinet. I have no good reason, necessarily why I am crossing the 250 Hz horn at 1k. I posted my measurement above, but of course this...

ya that’s likely where the truth goes. I had it once with electrostatics. Theyre most bitchy in regards of correct positioning in the room as we all know. They’re a lifetime task to find DPOLS. I tried to move around and found huge difference. Some c...

I have my passive crossovers arrived. They are built by hornFabrik. Everything is up to the spec I asked for and I really like their build quality. As of yesterday, I have now a more promising sound towards what I have aimed for. They are first order...

The new parts I needed to build the new crosovers arrived about a week ago, but I have been otherwise busy (for a change...), and now I've managed to get sick, so I am still only mentally toying with the project. I will try to work in some bread boar...

[quote user="serenechaos"]Did you use LEAP or anything like that, or just cross everything over 1st order as a guess, and tune by ear? [/quote]
Oh, no. I do not use any LEAPs or others tools, no time domain analyses or anything like this – the...

This is the project that I been thinking to undertake for years. I have motioned about in multiple times that Vitavox’s S2 lower region is very lucrative but unfortunately not exactly useable if the driver run all the way up, unless you are wiling to...

Ronnie,
Arranging the driver in a line array is a fierily straight forward thing. Also be advised that the arrays will less likely work across a short wall, and you need to use a long wall. Generally it is imposable to advise anything as any rooms a...

Hi Romy,Well, this is my (and my dad's) first horn system so we're learning/building one step at a time. Our motivation is simple, to use horns as low as possible.The very first DIY configuration was:TAD ET-703TAD 4002GOTO 505TTTAD 1603 Woo...

Here is my proposal for an ideal horn system. The concept derives from the really of the horns as I know them, the available park of the drivers, the drivers’ real capacity and from… everything else that I might comment upon if you would not figure o...
