Lol. Do you get some movement on clothes?

I get pretty good amount of clothes vibrating.

Where is the doorway?

I have missed a bunch. Happy birthday and awesome card. The hair trick is neat but what was that clicking sound? If you are rattling something get to fixing that. A silent, rattle free room makes a huge difference. I also get the hair trick.

Was that the side of your cabinet shaking violently?

Thanks MK. Yeah, addressing all of the rattling is going to be tough. I believe the clicking sound is the liquor bottles rocking back and forth on their shelves... I'd have to check again though.

Man, everything shakes violently... The shower curtain, ceiling, bathroom closet, everything just goes crazy around 15Hz and below. The sweep I ran was 100Hz to 1Hz.

Austin, do you have the THX demo with the mushrooms that pound with crazy bass? I watched that yesterday and the sound from the back of the room was louder than the sound from the subs. It was like there was a big bass hit from the front of the room followed by an even bigger sound from the back of the room - a fraction of a second later than the bass hit from the front - kind of scary actually. I'm not sure what the sound from the back of the room is, it seems like it's the entire back wall/doors/etc. I'm guessing that isn't good for my house. eek.gif

Welcome to the house wrecker club guys. biggrin.gif I spent about an hour last night adding extra screws to re-secure my drywall to the studs. The worst areas were the walls right next to the subs, go figure. tongue.gif

I am starting to not look forward to when I go to do that. Some screws are pulling from my acoustic treatments as well, and I pulled two nails clear out of the studs where I was hanging my old DIY screen in the storage room beside my theater. That was cool for second until I saw where I needed to do a touch up from where the screen fell over...The nails werent in that far but the french cleat setup just ratcheted them right out of the wall.

Oh, and there is this as well. Two stories above the theater, and I promise it wasn't there before the bigum sealed setup:




Man, I hate looking at that ceiling, but there is no way I am doing a chemical wipe of all my ceilings...

I do have that one one of my demo discs... I'll have to check it out tomorrow. Just got finished with "The Man With the Iron Fists." Highly recommended from one ULF to another...

31:00ish and 41:00ish are fun.

1:38:10 made my Clone clip WITHOUT bottoming out my subs. I have no idea how low that scene gets, but it was f*in awesome. Careful with your amp man. Scenes like that that really make me scratch my head and get me thinking, "Hummm, I thought I wasn't amp limited?"

I have my HPF disengaged on my SMS-1, so maybe... Well, I'll have to defer to others for their opinions.

Running my 8, I have gotten to the point where I didn't like how far the amp was going, but all I saw was the vpl light hit VERY lightly. It still woke me up a shade.

Of all the clubs... Not a fan of "House Wrecking."

Dayum beast! I guess it comes with the territory and I souldn't complain, but I'm not looking forward to reinforcing and repairing crap constantly...

It won't be constantly, I mean I still am rocking a drop ceiling for goodness sakes. It hasn't come down....Yet biggrin.gif

I haven't really had to do much damage control, but the further I am dialing the system in and the more extension I am getting as a result is starting to show some signs around the house of where I need to make slight adjustments.

You make-a your bed, you sleep in it right?

I've never had my amp touch the VPL or Clip lights with my SI's... Until that scene...

Haha after almost 35 years, it needed some more settling....I did however pull the carpet downstairs to check the foundation, no cracks....


I knew that would get your blood boiling a little bit!!!! I didn't really do that tongue.gif;)

Wow, clipping the clone? Man, if that's the case I'm probably not close to pushing the SI's to their potential with the CV amp.

I just bumped that flick to the top. I should have it end of the week and will report if I see the same thing taking place biggrin.gif

Clipping the clone does not make sense. Your drivers are 600 watts each and much more they would be in trouble. So even with 16 at 600 watts the clone has more power than the drivers can handle. If the clone clips than your drivers would be in trouble from too much power. So the question is what is the load, are the lights accurate, or something else?

In 4CF it was reported they could take 1,000 watts each.

What is the enclosure size (I know it's 4 drivers in each box) per driver? That 600 watt rating was for 6 cu ft box I think.

Hhhhahaha... Man, I would have had to punch your foundation in its brittle face if it started cracking.

Dang beast, I didn't see this pic when I was on my cell last night. That looks crazy! I sincerely don't like seeing home damage. My next space will unquestionably be a concrete bunker...ceiling and all.

If running 8 subs right now that is still 8000 watts at maximum. Is popalock ruuning an 8 ohm or 4 ohm load? Basically if he is clipping a clone his drivers would be at their limits at that point.

I thought of your CV as I watched the clip lights flicker...

Yeah, good idea. Let us know... Nice to get a second opinion to see if the results can be duplicated. I wouldn't be surprised if I am doing something wrong.

Are you running any kind of HPF at all?

Enclosure Size: 16ft^3 (~4ft^3 per sub)

Load: 4 ohm stereo (well recieving a mono signal from my AVR)

Power: 4,400 watts x 2

Power Per Sub: 1,100 watts

Posting up a video for your guys tonight is about as scientific as I can get in this scenario.

I can say that when the amp started clipping, I observed no nasty sounds from the subs themselves. That said, not sure what/where the issue is. Hopefully a quick video will somehow help answer some questions. The second channel of this particular amp was giving me problems when I initally purchased it. However, when I was having issues, only the second channel would clip prematurely... after a amp board replacement, it's been working flawlessly...

Last night, I observed BOTH channels clipping at the same level.
post #360 of 942
Simple, clone is 9000-14000 watts depending on load. Apply drivers as necessary so you either are amp limited or driver limited. Now 8 SI's should be driver limited unless running an 8 ohm load total then it would be close.
