A 15A circuit, running two subs being driven hard, will draw 1,600W.
By coincidence I called Mark today about adding a second HP and what it would do to the power draw. The answer is, "it depends."
If a single HP is producing 110dB and drawing 800W, adding a second HP and maintaining that same 110dB will actually make the HPs more efficient and you will end up drawing a bit less than 800W. If you use the second HP to increase volume to 116dB then you will double the power draw to 1600W. This is assuming a perfect theoretical model.
In my case I have enough volume so I would not be looking to increase the dBs and could easily add a second HP (or more) to the same circuit as the first. Your case may be different but without more details one does not know. IOW you are not being anal enough!
A 15A circuit, running two subs being driven hard, will draw 1,600W. Considering a 15A circuit is capable of providing 1,800W, when an AVR which is also being driven hard at ~350W along with 60" LCD television and Comcast provided DVR, will easily exceeding the 15A circuit limit. Now the internal wires start heating up and I don't wish to have to explain to family, friends or insurance company why I chose to overload a circuit when I knew better. The point, one may call me deserved names but I'm not going burn our house down because I didn't want to take the time to find out what's what with what.
Someone should explain to BeeMan458 how a circuit breaker works. I'd do it, but I'm on ignore.
Yes, you got me on the 6dB technicality which will reduce amplifier demand. Good catch. Of course you did remember to adjust your numbers for the distance from the subwoofer to the main listening position as opposed to standard readings taken at 1m. We have a 3dB drop between one meter readings and main listening position readings.
In the end, one only needs to be anal enough to prevent problems and not a farthing more.
I re-arranged my front Submersives last night and put them in the front corners. My corners are treated with corner bass traps (Gik sofit traps) and I didn't think that it would make much of a difference with the bass. Boy was I wrong! I thought that the seat vibrated before, now it rocks.

So you put one in one corner and one in the other? How did you have them before. Glad a little movement made such a difference.
He was probably never going to buy one. We have a name for them in my business. His loss!!
And I have names for people who play backstabbing rumor monger games while people are on vacation. And businesses who disrespect customers, especially in these economic times, go out of business. Don't be quick to bad mouth customers as there are too many other businesses out there who do respect potential customers. Care to say what your business affiliation is and what the name is you have for these customers so in advance, potential customers know what you think of them? If you're going be public about what you think about your customers, be bold and be open as to what you think of them.
You guys never stop with the digging and drama. I'm on vacation in the Sierra high country. I check in to see what's what with you guys, just in time to see more immature sniping. Good for you guys. Lake Tahoe, shrouded in it's storm mantle was a visual delight and the Fall Sierra-Nevada colors, with snow dusted peaks are absolutely stunning. Stopped in at 8,400' to say hi to Bodie, California.
And for the record, I have already stated, I have dental work to pay for and need to knock the credit card down (between the dental and the card, about $8.5k worth) and then I can step up and buy a Rosenut HP with an eye on a second one. It would be nice to receive the subwoofer without an uncalled for layer of hate attached. Until I return from vacation, can you guys see if you can keep the uncalled for back biting under control. If just so this forum can represent maturity of interaction? And if you can't hold it together, at least hold off on the backstabbing until I come off vacation. I understand, some people can only feel good about themselves by putting other people down.
From Bridgeport, CA, it's South, down Hwy 395 to Yuma, AZ and then out to the California Central Coast in Cambria. The point, life is too short to waste on childish backstabbing drama. People get fired from good paying jobs for far less than what is posted on these pages. A suggestion guys, to those my comments apply to, grow up and try being nice.
All those wasted posts when "just letting it go" is an option too.

Getting the last word in(or post) is not as important as your familys vacation so
enjoy and take things with a grain of salt. If you do end up owning a Subm HP oneday you will
understand why "words are wasted" when trying to explain the "Submersive experience".
Not responding to posts that fire you up is not the same as "backing down" . It becomes a case of
"it is not what you say but what you do."
GoodLuck and BEE careful while driving

What RC or EQ are you currently using? Did you re-run it after you moved the subs? If so, the SPL should not have changed. It should have been re-calibrated to the same level. The benefit of corner loading, (with recalibration), is an increase in system headroom. If you kept the levels the same as they were before, you're no longer calibrated properly. If that's what you want, that's fine. Just realize it's not the "correct" calibration.
i assumed that was a "raw" measurement, re: spl... but i shouldn't do that...
iirc, he's using an antimode... it wouldn't be surprising (correct me if i'm wrong, you know a lot more about this than i do) that corner loading the subs is giving the antimode a "better" spot to work from... possibly giving him better response in the area givin him the tactile sensation...
just a guess... if has graphs, it would eliminate the guess...
Been a long time since Ive visited this thread. My first gen subM is still doing great! Watched War Horse yesterday and the hoofbeats and cannon fire were awesome. I did get one clipping instance in a particular loud thump scene, maybe I should get the upgraded amp!
You only need about 3" from the face of the driver to the wall for spacing. You can gain another 5/8" if you remove the grill. In my own system I usually have the amplifier facing the side wall with the long 24" dimension of the footprint running front-back. Also remember that in many homes you will have >1/2" for a baseboard or molding at the floor line, and you only need that 2.5-3" from the wall. The twist-locking (PowerCon) power connection and XLR connector protrude 2" from the box.
