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...

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...
|
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...
|
Last month of two I keep thinking about the super-meaning of lowest octave in sound reproduction. It is not about the importance of the lowest octave for sake of audio reproduction, there is a lot about it in other pleases of my site and anywhe...

Hi Romy, Just a couple comments on recorded quality and dvds. If you have a chance try to find the DVD called Eroica put out by the BBC a couple of years ago. It is a quasi-reinactment of Beethoven's unveiling of his new masterpiece...

[quote user="Romy the Cat"]. What was your resonant frequency after loading? The 416 are 25Hz drivers, after loading and with two drivers it might be deep in teens. From the picture it looks like you keep the back chamber of extra large space, or eve...

After much consideration I desired to get my test crossover. I chose when for Velodyne SMS-1 that someone pitched at this site before. The unit has 6, 12, 18, 24, or 48 dB/octave low-pass filters that I need and runs up to 200Hz. I do not think that ...
|
Gera, is this an idea you're familiar with from a sonic standpoint? The horns are supposed to boost lower frequencies within their pass bands without adding their own sound, or - more realistically - allowing for their own minimal contribution to th...
|
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 Sussurro has an unusually wide loading range listed by Soundsmith, ranging from 470 ohms to 5k ohms. It is possible that more recent models have a somewhat tighter range between 470 and 2k ohms but I am not positive. The capacitance of Soundsmith...
|
Gera, are you catapulted from another planet? Are you sure that you want to drive a mid horn with Rowland amp? What kind 6dB high-pass filter used RC network? Why digital filter had an obvious advantage in the attack and dynamics? What does it mean “...

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...

God, I hate to bring this up as it seems you have given up on your quest for better monitors.Maybe I missed a thread somewhere, but reading over earlier posts you were looking for- high efficiency- tone- dynamics- sealed designZu Credenzas have same ...
|
I like your comment about LF being too dry and this not being because room is untreated.In the past, I have tried to "wet up" sound by making room more reflective ("live") and I am guessing that your room is fairly live now as untreated rooms usually...

[quote user="Bill"]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] Bill, the 6 "...

Nice job of keeping R off the ribbon. Like you said, who cares about circuit "damping" there, anyway, given the freaking magnet in that thing versus the 0 weight of the ribbon. I'd say it's "damped enough"...It will be interesting to...
|
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...
|
Gera, I have lived with similar for years, turned this problem all around many times. While something like 15" Tesla AROs should work well up to 250 Hz, I think you will have to get very clever to get more than flatulence or thumping below 40 Hz fr...
|
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...

Hello, thank you for your answer, I already read this very interesting link (this how I knew about this forum (like "yes ! there is weird people too"))I never saw too much parellele things too (excepte for solid states); I hope nothing is wrong doing...
|
An interesting excurse in past, thanks, Clark, you see you might be useful…. What I wonder is: considering your internal knowledge of Boston’s local FM market, how many more miles do you think we will be able to get o got the FM? I know that WCRB a f...

So I wrote one of the big DJ/producer guys at WFMT, complaining about the horrible sound last night.He wrote right back saying I was absolutely right, the Phil broadcast had sounded awful.Turns out FMT had made a last minute decision to take the PBS ...

[quote user="TonyB"]What does Linx16 card do in your tuner recording set up? Do the digital A/D signals only pass through Linx16 or do they get buffered in PC RAM and then go to the Linx16 digital output? Tuner audio sounded very similar directl...
|
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...
|
Well, this kind of reminds me of an experiment I did with multiple speakers each with a varied delay built into the signal path to emulate room reflections. This allowed me to manipulate and move the image around. The end result is to min...
|
I beg to differ with Romys assesment of my signature sound, one thing I found out is people are very,very different in what they like and dislike. An example is a "quote" reviewer (which will remain nameless) did not like my Stravinsky His...
|
[quote user="Romy the Cat"]Yes, the layout kind of not optimum. You might try to lay the transformers sidewise and to make the RCA atop, above the transformers. Still, I hope you understand that your hum has very little to do with layout. Properly gr...

...of wines and power conditioners and Bruckner and cigars. That said, I don't do cigars; I really, really do do Bruckner; power conditioners vary in their effect from place to place, day to day, and hour to hour (not only that, but most of them need...

Sorry, I was not clear (as usual...). I meant trimming per individual 45 tube type, not re-trimming for each individual 45 tube of a particular type. I doubt you will want to run your old globes the same as you run your new STs, etc.And since you a...
|
Romy,do not spit in my eyes as I do have solid state PassLabs 350.5 but even with this 50W Class A amp (push pull) it is exactly the same problem if it is switched off completely even for a short while. I can take ~ 2 - 3 days to be back to norma...
