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

I had great seats for a few of the Pink Floyd Division Bell shows and "Sorrow" taught me that bass can rattle all the little bones in your ears. Not very comfortable.
If your dog was stuck under the house and kept barking would that be considered a "sub woofer"...? Just thought I'd ask...

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?
