    Replacement for Onkyo 707

    Not yet. Sent an email but no response yet. I'm going try again after the weekend.

    Replacement for Onkyo 707

    I do have the receipt but unfortunately it is a refurb from accessories4less and only had a 1 year warranty. Unless there is something specific to this model that I am not aware of...

    Replacement for Onkyo 707

    Hey everyone, I've been having issues with my Onkyo 707 and am now looking for a replacement. The Denon 4311 looks nice but I'd like some second opinions. For the past several months, my 707 will randomly lose video while watching (TV, blu-ray, Xbox-source doesn't matter). The sound still...

    Is diet soda worse for you than regular?

    No offense, but your student is incorrect. Fructose is a naturally occurring sugar found in many fruits and actually composes half of cane sugar (which is primarily sucrose). Both fructose and glucose are 6 carbon sugars; glucose is arranged as a hexagon while fructose is a pentagon with an...

    Reference level

    You get a 3 dB increase either way because not all the acoustic energy reaches the listening position in phase and coincidently. If you stack 2 subs, everything is doubled and the energy propogates in the same way, yielding a 6 dB increase.

    Reference level

    If the acoustic sources are not co-located in space with identical dispersion patterns, phase at the listening position is random. Every reflection off every surface in the room from every speaker contributes and a significant portion are not in phase. That's why you don't get an ideal 6 dB...

    Reference level

    You haven't listened to a single thing anyone on this thread has told you. Speakers that are NOT IN THE EXACT SAME SPOT combine at 3 dB if they have the same phase and amplitude. They ONLY combine to 6 dB if they are stacked. Look at the links I provided (it has a breakdown of the formulas...

    Reference level

    You don't have coherent signals. Real speakers are separated in space which makes them by definition incoherent and gives a 3 dB SPL increase when combining identical sources. You'd need all the speakers sitting on top of each other to get the 6 dB increase you're describing, which isn't how...

    Reference level

    You don't have to convert units. You just have to know how to manipulate logs. Or, you can use your method but you have to add the square of the pressure from the channels and take that sum over the square of the reference pressure because the sound sources are not co-located/incoherent. You...

    Reference level

    Vaughan, If you're considering just pure signals, then you are correct that the sum will be greater than 115. From what I gather, you want to combine one 115 dB tone with 5 105 dB tones (all at say, 40 Hz). Adding those together will yield an spl of ~117 dB. You can use this calculator...

    Health Care in the USA

    Drugs are extremely complex and often unpredicable. Very small differences in structure can have large changes in efficacy. Plus, a lot of times the mechanism is paradoxical. Beta blockers, some of the most efficatious heart meds in use, for a long time were contraindicated in heart failure...

    Pregnant Women Receives Wrong Drug

    We still get those lectures except now it's called patient adherence. Apparently compliance wasn't PC enough :rolleyes: One of my lecturers said that about 20% of patients don't even get their meds filled so she has most of them take the first dose in the office. Seems kinda time consuming...

    Pregnant Women Receives Wrong Drug

    Thanks! Bummer about the flu. It's never any fun. I'm actually in my second year, so maybe I should change my location to "Light at the end of the tunnel." I was the lucky one to do the cutting in anatomy (missed the colon thank God). Just have to make it through step 1 now. IIRC the woman was...

    Pregnant Women Receives Wrong Drug

    I agree completely. There's way too much of this going around, even from otherwise intelligent people. Still feel bad for the mom. Would folate be useful in this situation?

    What happened at this site?

    I've been away for a while too and my sentiments echo yours exactly. The demonstrated lack of reading comprehension in the Hsu thread is appalling. How hard is it to understand that Hsu made a big box less obtrusive but in the end it's still a big heavy box? And since when do readers of this...

    upgrading tweeters.

    You'll need a measurement mic to get that kind of data. An SPL meter isn't accurate enough and won't have the bandwidth to measure a tweeter. http://www.audioxpress.com/magsdirx/ax/addenda/media/koya2811.pdf If it's just for sh!ts and giggles, then it doesn't hurt to give it a try.

    Center and Sub Issues

    That's weird. Both numbers should be the same (at least in my experience, outside of the sub). Try bumping the center distance up a foot or so. Also try setting the distances as close to what you measured as possible (Remember to measure from your ears to the tweeter). If either of those...

    Center and Sub Issues

    I think your problem with the center might be because it's closer to you. When I first got my center channel, I played around with it about a foot or so in front of the TV and the soundstage was just off. The center was very prominent and sounded separated from L and R. What is the distance...
