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...

I am sorry; I do not follow what you are saing. I see no relation between a need to use a crossover with DSET topology. The Cat...

Yes, Paul, you are right that it has to be pointed that the frequency extension, by itself, does not guarantee anything (but that’s why I posted the thread in Audio For Dummies section :-) ). OK, now let’s see how the tweeters should be used (in cont...

Yes, seems an obvious winner to me too. I'm making some speakers for a friend and the big decision is one amp or two. A 20w tripath and a 5w El84 set per channel is a sensible and cheap combination. The tripath and line level crossover section could ...

I was just thinking.Isn't an riaa filter just a line level crossover for one channel (times stereo)? So what you say makes total sense....

My experience is limited, but I tried it a few times (300B, 845, OTL ...) with 8 ohm Speakers, 92dB and a crossover, which is simple and never got a result which was close to a high sensitive speaker (98dB ...), no breathing, no air, Headroom was lim...

I think what I gained from the basshorns were 1. "Speed"or lack of momentum.Specifically deep notes on piano.The sensation of that leftmost keys with the initial impact then followed by the resonance from the instrument as separate entities.I...

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...

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 ...

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...

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...

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 ...

...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="diz1"] Are the First reflection points for horns speakers are different from other type of speakers? [/quote]Yes, the sound from horns does not propagate straight along with the line of sight but it curves according to the Xchyler eq...

[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....

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 ...

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...

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...

Interestng, I did not near horn load Electrostats. What the profile and what the mouth rate of your horn? What the resonant frequency of Electrostats you have before and after loading? Are you driving the Electrostats direct from plate or via a trans...

Romy, I thought the Ref3 mm-de capos sounded pretty good last I heard them. No idea if they are ported or not. I've been told the crossover is rather simple. To me, they did a good disappearing act. Probably expensive.For dece...
