A warning to all about HUGE Subwoofers

So I just bought a Velodyne HGS18 yesterday and its amazingly awesome. Enough so that I know that it can crack concrete and after playing with it a while i genuinely have realized this has the potential if unleashed to destroy a house.

I decided to do a test tone to see how it did and at 10HZ this thing will rattle your whole house (I listen to rap amongst other things, I'm no stranger to playing loud bass)and that is with very little volume. Be careful when you look at subs in accordance to your building.

I always thought the subs that had that potential were awesome and amazing which they are (at least this one) However it isnt fun be afraid to turn up your sub for fear of tearing down your walls. It wasnt that bad but it seems that in 2 seconds or less if its going to loud and low it could do some damage. I can only imagine what it would have done my volume was any higher or if i let it go without being next to the volume switch.

On a side note hearing frequencies that low is an amazing improvement and far better than I had anticipated

So how does the sub integrate into your system. Is it seamless?

My room is an L Shape about 12' Wide by 20' deep turning into an L about 10' in so i have HUGE suckout and there is no door just a 5x6 doorway so I dont have an Ideal or even all that great room but it works for now until I save enough to Remodel (Really Rebuild) a garage/storage unit on my property maybe 30 feet from the pole (maybe 70 feet from the transformer) and make that my listening room 15 feet wide by 20 or so deep would work just fine.

Back to the question, not entirely shockingly and I do meant shockingly better than the HGS-12 which I thought would have quicker speed but no, it keeps up, I even tried it at 80HZ and its no slouch, and I cant recommend anything I have heard better for acoustic music, Im not getting the output I dreamed of but my room sucks

The only damage my subwoofers caused was the drywall screws backing out , you could see rows of screws where the studs were . they got so bad that I had to rescrew the walls then laminate a second layer of drywall to the first layer using no screws or nails , problem solved .

Thats actually very impressive. What subs you use?

I have 2 ads m4's and 2 ads m3's in my system.
The 4's are on the fronts, the 3's are on the sides.
My system in a finished basement and I can shake
the cement floor.
It's taken me months to stop all the rattles, but
it is worth it.
I tuned everything to be flat and smooth on the low
end.
It sounds great, but on some recordings I hear tapping
on the floor or mike boom vibrations that can make
you nauseous.
Years ago I heard a parrasound 18 inch sub and it knocked
me out of my chair, but was clean and fast.
Would love to hear it again,

Of course no system is really high end and all that unless it's got the balls needed to destroy the house, right?
