Hi Keith,That is an interesting way of setup the S150 horn. Most of GOTO setup that I have seen set the S150 high and point down to listening position. All of them crossover the S150 + SG505TT at 200Hz to 1kHz range. I wish that I h...

SGSG-37FRP (designed for mid-high ranges in a smaller system). 56,000 yen Driver frequency band: 400Hz - 10kHz, " optimal crossover is 500Hz or more" 110dB, 18,500 gauss

Hi Fellow Forumers,This is my first newbie post :-) Do any of you have any experience with running a Lundahl 1627 in a Full Range Melquiades with Avantgarde Duo Omega speakers?The other options are to get some custom Amorphous OPT's <50R 350mA 8:1...

Maybe it is because I have very low audio-IQ, but I don’t understand the implementation of your ULF channels - how is it possible to inject +30dB at 25Hz without changing the sound? What is the crossover frequency of that channel? Could you post a ph...

Ok, understood. By the way, Dayton Metallized Polypropylene capacitors are fine for this experiment right? I don't have to buy expensive ones just to have a good idea of the passive crossover sound quality? I hope not.-Herman...

Got the ultra low DCR toroids coil and pit them in use. Yes, it was very right move and they a bit trimmed the midbass tail. Playing with inductance and listening how the midbass decays (measurements are worthless in this case) I ended up with 4.8mH ...

I did mention to Steve about the angling of the horns and he told me that he started with them horizontal, but preferred them angled as in the photos. Who am I to argue! :-)The crossover phase change was because he's using second order crossovers whi...

Well I have some literature from the Show and about the Audio Tekne speaker I can say that:- it has an outboard crossover, which I guess is passive and uses a lot of transformers- woofer diameter is 380 mm...

ok. maybe we have a different understanding of "electronic equalization". We do not use active (i.e. electronic) equalization in the amplification chain. There is of course some equalization in the passive crossover but I really don't see what's ...

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...

Having tried many types of coils nothing was as transparent as the NORTH CREEK 8 gauge air core coils.I do not think you will be happy with the JANTZEN or any other using a metal core.They are much cheaper than the NORTH CREEK and look better. I, too...

Despite the fact the I lost the quality of the lower knee of my midbass horn (I guess the primary resonance went all the way down) I keep trying to catch the right termination of midbass low pass filter. I bought those expensive 20H coils and added ...

Hi, I want to get inside a pair of Pioneer Exclusive TAD 2404. I have unscrewed the external crossover on the back panel and all the other screws including those of the two wooden crossbeams but the back panel does not budge. So I tried taking out th...

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

It is comforting to know that the Vitavox is in the running with the Tannoy. I am very interested in the results - also with the crossover intentions....

That last known configuration.
Actually I was running in my head multiple times and last known configuration. It was my friend and out of preamp into two separate B2 via a radio shack level cable, send to default Tannoy crossover and to Red d...

Recently there was probably nothing as low in audio as the BS surrounded Kharma loudspeakers. Each single step Kharma takes is further and further in-depth Kharma into the realm of bogusness. It is not that I find that “Kharma the Manufacturer” or “K...

...to assist spiritually!Interesting view on IT. Indeed the multichannel SET with line-level crossover changes the perspectiveon the coupling techniques. This rules A2 out (unless cathode follower...blah blah blah)And paralled drivers? May I ask why ...

[quote user="Paul S"]Probably not news, but: http://www.supravox.fr/anglais/haut_parleurs/135_LB.htm Another one that at least looks the part.[/quote] Thanks, Paul. This Supravox 135 LB indeed looks like an interring driver for a project of mine. I h...

[quote user="zanon"]Do you mean that if you begin with digital source, it does not matter whether you use a digital crossover or not since the "damage" has already been done?[/quote]Absolutely not, it is not what I meant. I meant that the only advant...

2 options. 1. Put a door in front of the alcove that is casusing the resdonance and line it with 6 " of sonex. May turn the space into a bass trap at 60 Hz.2. Put an adjustable notch filter into your crossover at 60 Hz....

[quote user="Paul S"] With the Wright amps the G2Si did not seem to live up to their efficiency specs using my little cap and coil crossover. I can't offer good descriptions of their sound with the ML2s until I get my TT going, but ...

So this amp would not have to deal with a crossover? One R and one L in the signal path, it looks like a headphone amp, maybe a dream circuit for a light piston, HF only, given no cap/coil load at the [ribbon] driver.What is gain...

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...

Lastly, put in a line-level filter at the input instead of using a speaker-level crossover. The same circuit as is used with your 6E5Ps would be fine....

I had a Behringer DCX2496 that used for nothing and I think it got broken. I do not want to by another one. What I looking for is some kind cheap, no more than $100 solution that would allow be to have 4 order filters and crossover point up to 250hz...

In loudspeaker and amplifier design we could use more channels to have better result (like 12 channel DSet concept) but i never seen any DAC/Pre to have more channels.It seems i am speaking about moronic idea but it is interesting to me think about t...

Sorry I misread, I thought you endorsed the use of PP tube amps with compression horn drivers. Well it looks like were still in the same situation of not making them work. I could go on about why I feel they don't work, but it won't chang...
