I have an Mirage Substrata 1500 subwoofer whose construction is very similar to Bob Carver's subwoofer designs (an active driver on one side and a passive radiator on the opposing side). The subwoofer just loves to dance or vibrate violently during (very) loud rumbling/explosive movie scenes though I have put some 40 pounds of diving weights on it. Will something like the Velodyne HGS-12 (II or X) do the same thing?
Follow Ups:
Thanks guys. I will to get a Velodyne DD12 in the near future.
and the whole neiborhood will be dancing. Or at least your whole house.
This will help figure out what's wrong. If the sub is making bad noises from the woofer or passive radiator then there is either something wrong with it or you are just overdriving it. If this is the case you'll need a bigger and/or better sub.
If the sub is actually moving/bouncing.... strange. It should be heavy enough to keep itself from moving. Are you on a hard floor?
If your sub is moving around, it is either defective, poorly designed or you are playing it at levels for which it has not been conceived. At extremely high levels with lots of sub 40Hz bass, the cigar box on my sub vibrates slightly but the sub goes nowhere!
somewhere else. My cigar’s humidor is inside my dining room buffet cabinet and cannot be disturbed. Besides who wants to smoke a cohiba that dances in your mouth.
Keeping it on the sub, keeps it within arm's reach in the music room. Much my favorite place for a good smoke. Besides, the subtle vibes make sure that the humidity is evenly distributed within.
The Monte Cristo box of cigars that I have just bought had a humidity problem it was a little dry right out of the box. Surprises the heck out of me as the box was tightly closed could be that this was an old stock. However, I have them all back to its proper state by placing a slightly wetted small sponge inside my humidor. I agree having the cigar in arm’s reach is the only way to go in my case I have to keep mine away as I have a toddler who like to poke into everything.Nothing can beat good music with a good cigar coupled with a glass of Porter wine. It certainly nourishes my soul at the end of a long day.
except I no longer have toddlers to worry about and I prefer cognac or grappa to port.
Nope. I have a Velo HGS12II and a HGS15II in my system. Neither one moves at all. But then again, I don't have my subs cranked up either.
hwahlee,Thanks for your reply. You mean the Velodynes don't generate any funny vibrating noise at all?
That's correct. Neither sub generates any funny noises. The workmanship of the subs are impeccible...it should be for what they were going for new. Fortunately, I've been the beneficiary of the drastic price reductions from the new Velodyne DD series coming out. It's too bad the piano black finish isn't being carried over to the new HGS-X series. They are exactly the same subs as the HGS II subs I have now...except no piano black finish. Velo said they eliminated the piano black finish because of cost considerations. The only gripe I have about the HGS series is that I had an issue with reliability. My HGS12 had problems after about a couple of months. The sub would for no apparent reason go into oscillation while at idle for a couple of seconds and then stop. It did this at idle with no input signal. After a while the oscillation turned into spurious noises that came from the sub and trickled down into the mains I hooked up to at via the high pass filter outputs. My dealer was able to replace the sub with another one and I've had no problems since. The 15 I have hasn't given me any problems at all. A friend of mine also had problems with his HGS12 which was sorted out when he got a replacement. He eventually traded up to a DD12 and a DD15 which he's extremely happy with.
