When measuring the response of my room, I found that there is an enormous null from about 80hz to 110hz. It's about 10db below the rest of the response. My first thought was that it was a phase problem between my sub and mains because the sub is crossed over at 80hz. But I did a measurement...

Hi, I'm thinking about purchasing a new TV soon, and I've seen a couple models that really caught my eye in terms of price and performance. One is the mitsubishi WD-52631 52" DLP. Looks nice, and costco has it for $1349. Also at costco is the JVC HD-56FC97 LCoS for $1699. It also...

I saw that costco has this plasma tv on sale for $1500. But before I snatch it up, does anybody have any feedback on this tv and it's picture quality? I would like to get the 50" panasonic they have, but I haven't seen it for under $2000, and $500 is a pretty huge price difference. So any...

I'm considering upgrading to an HDTV, but I've read plenty of posts here about how most/all of the big-box stores have their display model TVs poorly calibrated. Can anybody recommend a good place to shop for one in the austin area, preferably with helpful/intelligent salespeople? I moved here a...

Hi, I have a friend who wants to build an inexpensive subwoofer. He only wants to spend a max of $125 and ideally $100 on the speaker and amp together, plus whatever it costs to make the cabinet. He's hoping to use a 12" woofer. Is there anything available in this price range? My first...

I have a question about house curves. I've read many threads about them, but I've never heard anyone talk about using the equalizer in their preprocessor to help create a house curve. I have a sub with a BFD, and I found the easiest way to make a slope for my house curve was to set the bass...

I just ordered a sub today, and I'm not sure where I should put it in the room. ht tp://home.austin.rr.com/ggreenway/room.png In the image the black lines are normal walls, and the red lines are a railing that opens up to the rest of the house (most immediately a huge open space). The...

Hi, I'm helping my brother shop for a new 7.1 receiver. He has $600 to spend (fairly hard cap, maybe add a bit for tax, but not much). What are the best options? He's going to be more comfortable buying something new than used, although buying a "last year's model" would probably be ok...

Hi, I'm interested in using a computer to measure the response of my speakers, instead of doing it manually with a ratshack spl meter. It seems like it would be much easier to tweak something, then just hit the Go button and have the computer generate all the tones and take the measurements...
