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

Heck I can kill termites with a dd10. I only need to find their resonant frequency.
I used 2 HGS 18 subs with a rear ML descent sub. I used to play all 3 as loud as they could go. This was all the time for 2-3 years.NEVER had one issue. Not even a picture off the wall from other nearby rooms.

I can tell you a HGS 18 isnt strong enough to do damage. I run much better subs these days and still no issues.
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 .
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.
