Yes Wayne, that's about all it takes. Pretty absurd, I know. Kind of like the ultimate DIY tweak. LoL. To be more specific, the entire list of devices one needs, except for a cheap computer, is this: 1) 32bit Sound Card - I bought the M-Audio Revolution 7.1 sound card ($80 USD), which has...

Anthony Gomez, I wish I knew about your software in the past, it really would have helped me quite a bit. Anyway, since the BFD can only correct the frequency response mainly for one sweet spot in the room, I don't understand why you are not going all the way, and use a room corrction...

It's not a sub, but when the US launches to a missle to space, there is a possibility the bass produced goes even deeper.

Not exactly related, but no discussion about "biggest baddest..." sub, can go without this one. 110 dB SPL starting from 9hz... For some reason the first picture always remind me of the movie "Silence of the Lambs"...

Wayne, As I've said, a multichannel convolver is not yet available for Windows (it is for Linux though), so multichannel HT is not yet possible with DRC. When I watch movies, DRC is off. Turning DRC on and off is very simple (just a push on the PC's remote), since we are talking about a...

Richard,

David, Are you sure about this ?. I've talked with several people who personally measured the ECM8000 mike, and they all confirmed this graph: Pretty much Flat up to 10khz, and while not flat above that, it is still not very important, since our hearing is not sensitive for these...

LOL!, thanks Chu.

Wayne, Regarding the DRC code I'm using, it was (and still is) developed by Denis Sbragion, over a period of 3 years, at his spare time. He once said that he did it out of frustration. He really needed it, and couldn't understand why no one else has developed such a code for the PC, considering...

BruceD, The reason why you see no information below 200hz is just because that screen in ETF wasn't ment to show it. As you can see from the images, the high frequency waterfall uses a 0.7ms Gate Time, while in order to get meaningful results in the bass region, you need something like a 100X...

Mike, As written in that post, the first one (the Dirac Delta), is the most linear. Only problem is that it is purely computer generated. All the other graphs are real from different states of my system and room. Is there any graph of them which look VERY similar to the Dirac one ?. :-)

Mike, Read the post right before yours (you posted yours a few seconds after I posted it).

Ok, in order to overcome the link problem, I'll copy&paste that post into this thread. Take notice that this post is #304 in that thread, so some things will look out of context in relation to this thread, but you'll get the general notion. btw, "DRC" is a digital room correction code...

Sure Thomas, but in order to judge correctly, one needs to have all the facts in front of him, and only then to try and make decision. Be honest and tell me that your system ever sounded anywhere near as flat (in both frequence AND time domains), as the one in the last waterfall graph. I...

I don't understand, did you read the link I provided, or didn't you ?. Please, read it first!. The reason why I am in a very objective position to judge this situation, is becasue I too said the exact same thing as I quoted above. You'll have to take a look at the graphs, and see the changes...

It goes something like this: (I heard it mainly from TacT RCS users) "A truly ruler-Flat, 20hz-20khz frequency response, even with time domain corrections, is not somthing to be desired when listening to music through speakers. It sound too bright, uncomfortable etc...". My take on this...

Since I live outside of the U.S (and not even in a country which its main language is english), I knew I could never find the right word for "Burlap". Also, the PartsExpress.com transparent fabric is too expensive for me (with shipping and taxes...). This is why I've decided to go on a hunt...

Pete, This is why I've ordered 110 square feet of 6" polyurethane foam. Apart from this, I will be using a room correction software. The combination of both, I hope, will give me a more even decay throughout the spectrum. If not, then I would be able to say I've just made the most expensive...

Pete, I really want to believe that what you say is true, since it will save me much money, but how can you explain the fact that those who built DIY absorption panels in the past, always took care that the outer cloth is not reflective (not absorptive!, if it is absorptive to higher...

Pete, What worries me about a cloth which is not 100% transperent, is that it will reflect (not absorb) the higher frequencies. Hence the overall feeling will be of a bright sound, in the room.

Chris, so you say Burlap is better... I'm going to use it with absorption panels, so I guess that means just the opposite for me. ie. the "sparkle" is going to *remain* in the room, which is a bad thing. If only I knew a place to order it online... In America I saw that burlap is cheap, and...

Tim, I don't understand how Jon can say, in the SAME sentence, that putting the panel, 4" from the wall, will dramatically improve the bass absorption, AND, that having a rigid back to the panel, will also dramatically improve the bass absorption. It simply sounds like an oxymoron to me. You...

for an aesthetical covering for the absorbing panel: Check out this. I can get it for less than what the buralp costs in my country. But, if the burlap is better, I might go for it instead.

Pete, what I'm asking is, why do you need the absorbing panel to have a rigid back (like pegboard), when you have a rigid wall behind the absorber anyway ?. One of them seems to be simply a waste.
