Miab, since what I became an expert in cables? I am as much as anyone else – a subject of accidental discovering...
I do not use in Injection Channel any fancy cables. There is not a lot of need for it. The Injection Channel is mixed with M...

Zanon, I do not mean DEQ, but that is one way to do it. D[SET] is another way; and it can be done in real time, by a couple of means.If you actually settle on the mid-field monitor approach, you will want that sort of speakers installed before you g...

Mani, I have long run an 8" Lowther DX4 down to 150 hz, over 2nd order high-pass. My impression after plenty of listening is that I wish I could cross it at ~ 400 Hz. The "problem"is not simply how "low" the 8" driver will go but it is also a quest...
|
|
Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

On initial installation of my borrowed 1050 i used power cords i have as extras. Did so cause i was still using my BPT for everything but my amps. I had a hum and high pitch buzz from my speakers. Replacing the power cord feeding my amps was the cure...

|
Paul I have to admit being wrong about "BUdification" (enabl doted Lowther) process . I don't have explanation besides lenghty "brake -in " time but I would not bet on that. It may be a show stopper for you but I also admit liking them better in fron...

I confess that at one point I tried PM6As in 2.5 cu. ft. vented boxes. Lousy, tipped-up balance and soggy, one-note "bass", contrary to the designer's claims. The only thing good about it was that the box did not add c...

As I am slowly put Macondo back to the business a question come to my heard: how can I make the Injection Channel sexier visibly? As now Macondo is re-assembled and reinstalled but with no Injection Channel sitting atop. I extend no room for argument...

Public - now that is broad. The Public wants easy; not perfect. I would offer a simple two way: 12" paper cones LF with first order low pass [not a horn]. Iwata or Yuichi radial hyperbolic [MF & HF] horn above with first order medium-high ...
|
|
May I at least ass-u-me that you plan to high pass these horns? If so, go ahead and figure that in, too. In any case, just looking at 70', impedance is not the only number you'll be running up, and the last place you want this load is for LF chan...

I think it might be very interesting to introduce the high-pass filtration for tapped horn and to see how it behaves. It is not only about thermal overload and restriction of excursion. The unloading of none-used bass generally clean-up the transpare...
|
|
Yes, tapped horns are lower efficiency, mine are 105 dB (not 108 - 110 dB like the rest of the system). I don't even KNOW that SET or Class A is automatically appropriate for tapped horns... Something like op amp driven PP in class AB might even wo...

AlloOnly the cheapo Shure see-saw... perhaps I can improvise a balance to check the weight.I thought about the compliance business, as the HK diaphragms look like the surround embossing is narrower, which would make them less compliant (if they are a...

[quote user="ayebee"] The horns that Stereo Lab make are very good, especially considering the relatively modest prices. I bought the "Ultra-Fi" version of the 140Hz horns and they are of course not completely free of resonance ….Present system consi...

I do not understand from what you said the sorts of problems you are dealing with. What are you using as high and low-pass X/Os. Where and how you cross the drivers can make huge differences in the sound. Also, how did you throttle back Macando to ma...
|
|
The best midrange comes from compression drivers, it has that minuteness, transparency and dynamics that no other topology can offer; the main problem with them is that they only cover a very specific mid frequency ran...
|
|
I hear you, Romy, too many other things going on to do this full time, like "the old days". To save time and effort, you could try to "repeat" the original Dannoy configuration (same gear and location) and hear if it is "repeatable". If not, you're d...

Romy,Interesting video. The first thing that came to my mind when you were talking about HF colours and the "clean" RAAL Waterdrop tweeter, is perhaps adding colour to the RAAL. Instead of blanding out the midrange S2 and injecting HF colour with t...
|
|
Yes, a cheap inductive l-pad between OPT and S2 in midrange channel. Interestingly, the frequency response of the first order Lazy Ribbon is remarkably similar to a response you posted somewhere on this site of the Water Drop with third order filter...

Amir, it is funny to hear that you like $4,600 Purist but would prefer $10 Belkin SPDIF. The Synapse is basically an effective low pass filter, albeit this seems to help many systems. Like I said up the thread, I have not concerned myself with SPDIF...
|
|
Romy, you have said part of the Magic is the interaction between the Red and the Scanspeak "passive radiator". Could it be that reducing LF to the Red would decrease the "potency" of the intraction between the Red and current passive driver? If yes, ...

I have already got a tape recorder and now here is what I am thinking. Since there are quite a few tapes with Dolby A, Dolby B, Dolby c, Dolby S, Dolby SR, DBX and since some of the tapes were not properly EQ I would need an abili...

I think I found a good configuration for de-emphasis. The air caps will not work as there is nothing to amplify the capacitance. RC filer with cap to ground is good but I would like to have the entire de-emphasis with no capacitor at all, it will be ...
|
|
I recently could not pass up a good deal on a EAR 834P MM, so I will have the opportunity to compare it to my current phono stage. It is funny since I had planned to listen to EAR phono stage in my system about 10-15 years ago when I lived in Santa M...

It is nothing to do with Wisdom. It is my principle of application of “cost” as a common sense design tool. I do not bitch that Duelund caps are expensive. I just try to find a rational solution for using them that would embrace their price. My ...
|
|
Romy, Just a few notes.... I did use the term "crappy" in the connection with the tonearm in an ironic sense. Have you lived so long among US Americans you lost your sense of irony? Also, i do not suggest crappy Phonostages, merely ones with low inpu...

[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...
