If there are any forum members that have access to both analog and digital radio shack level meters at the same time would you be able to verify the difference in readings as posted here: http://www.nextlevelav.com/forum/showthread.php?t=907 What the person did was have both the analog and...

I actually did that a couple of years ago so it is kind of hard to remember but I think maybe a couple of hours. After a few plots you quickly get the hang of it. What I did was after graphing the initial response on the Excel spreadsheet, I drew a flat ideal response line on the same graph (I...

But when I used my 11 filters shown in the thread here: http://www.hometheaterforum.com/htfo...ghlight=Warner, it looks so much better.

DavidBelis, I also have the Logitech Z-560's that I purchased earlier this year here in Calgary from a local computer store. I have also noticed this exact same "problem" that you are describing. And like you also described, it is more noticeable when I have the volume control at lower...

MingL, I followed your advice with using a fixed amplitude slow frequency sweep (the low frequency sweep in AVIA, actually) with the 111 Hz and 124 Hz filters turned off. I could easily hear a dip in the frequency response at around the 111 Hz area. When I added the two filters back in, and...

Why would you not cut anything at 20 Hz? Without that cut, wouldn't that area be out of whack compared with the rest of the frequency response? Also you said personally you don't cut anything below 30 Hz. Any particular reason?

Hi all, I had posted my attempts at BFD equalization of my SVS sub last year, fooling around with house curves and such. I decided I wanted to try things again with a flat response in mind with my sub and front mains which I hadn't tried before (previously had tried a flat response with sub...

Have you guys seen this site by a woman named Wendy Carlos (who is a composer, musician, and recording engineer)? She talks about the ideal surround sound speaker placement, then scroll down to the worst surround sound setup for 5 channels (which has the surround speakers behind the listener)...

Hello again, Wayne, I'm not sure if you saw my last post on December 1/02 but I was wondering if you could comment on my change in graph response and my subsequent need to re-equalize my response as seen in the post mentioned above. Again, the only thing I had changed was both the subwoofer's...

Aarrrggghh! I was listening to some music, then some sine wave test tones and sweeps, and something didn't seem right. I decided to regraph my current frequency response. This time I took SPL readings with the subwoofer and front mains and this was the result: Where did that giant hole at...

Hello Wayne, I have been working on my new house curve on my own. I decided on a 14-15 dB house curve from 100 Hz down to 32 Hz. Starting with the November 20th posted unequalized graphed response, I brought down all the peaks to the level that I wanted. I was then left with a bunch of valleys...

Wayne, I listened to some movies and music. I'm still not sure. When you have a proper house curve, if you set the level of the subwoofer to be equal to the mains using AVIA, should the level of bass sound adequate. I found it didn't so I then set the level of the subwoofer to be 3dB above...

OK, Wayne, This is what I have been doing. First off, I decided to further tweak my flat response. The filters I used include your original suggested 5, your next suggested 2, and a couple more that I added myself: 20 Hz, 17/60-octave, cut -20dB 22 Hz, 3/60-octave, cut -5dB 25 Hz...

Wayne, I was following the instructions at the link you gave. I initially tried the same settings he did, that is: 366 Hz, 120/60, -15dB There was no change in the graph. Then: 366 Hz, 120/60, -23dB with absolutely no change in the graph. Then I tried: 366 Hz, 120/60, -40dB...

Hello again, Wayne, OK, this is what I did now: I bumped up the overall level of the subwoofer using AVIA as a guide to where I had it before (about 2-3 dB above the mains) and took new readings and made a new graph with my previous 5 filters still intact. I then took your suggestions along...

All right, I got the BFD today for $229 CDN + tax. Hooked it up, and tried the filters and settings suggested by Wayne starting with the 20 Hz filter. After applying the first filter I retook the SPL readings and regraphed everything and then tweaked it and regraphed until I got it to what I...

Hi again, Wayne, Thanks very much for your offer to help. I moved the subwoofer to the front left corner as you suggested and here are the readings: with the resultant graph: It looks to me that this might be a better location to start. Do you agree? I haven't got the BFD as of...

I have a single SVS PCi 20-39 subwoofer and a Yamaha receiver (fixed crossover at 90 Hz). Using the radio shack SPL meter and sine wave test tones I came up with the following readings: and the resulting graph: My home theater room is Length= 26.5 ft, Width= 11.0 ft, and Height= 8.67...

Oh, I see. Thanks a lot for the reply Guy. By the way, I just ordered the AVIA DVD online for myself. Hopefully I'll get it within the week. I'm very impressed that you, the creator of AVIA participates in these forums and are willing to spend some time to help others out, even if they...

So Steve, You are saying you calibrated the color and tint controls on some TVs using the red filter and corresponding red color bars in the AVIA disc instead of using the more common blue filter and corresponding blue color bars. Is this correct? You also said that the picture looked good...

Hi All, Just wondering. Since it seems that a lot of TVs have over-emphasized reds (Red Push) to some degree and that it is more noticeable to us viewers especially with skin tones, why do we set up the color/tint with the blue filter rather then a red filter. I know that the proper color...

Again though, Which patterns in Video Essentials can one use for centering and can one still use the off-center VE overscan pattern then use another pattern in Video Essentials to do the centering as I asked in my first post. Please restrict answers to Video Essential test patterns only. Warner

I have a Toshiba 4:3 non-HDTV RPTV. I have read that the overscan test pattern in Video Essentials is actually not centered properly and everyone seems to recommend that one does not use it. Since I already have Video Essentials I do not wish to purchase AVIA also(it costs over $75 here in...

Chris, You'll never believe this. I just received my Radio Shack SPL meter in the mail which was sent by my wife's friend in New Brunswick. Previously that day I had my wife call her friend in NB because I hadn't received it yet and was wondering when she had mailed it. Her friend relayed...

Hey Chris, I did find one searching by myself at Radio Shack's website. It was located in New Brunswick. My wife has a friend that lives there and she phoned her up and as far as I know she has bought it already and it is in the mail now. The Radio Shack store in my city said they could get...

Hey Chris, Thanks again for your efforts. I'm going to exhaust all my possibilities in Canada first before I look to the States. I'll go today and bug the sales guy in person to do the search. Before when I had talked to him, he said that if it was located in another store and I wanted it...

Hi Chris, Thanks for the looking so far. I inquired at a Radio Shack in Calgary. The sales guy said he could search all of Ontario in one shot and he found two stores in Toronto that had it but he also said that each store showed only one in stock which he said meant that they were open...
