Subwoofer

[Berryp186]

I am new here and have been looking around here and i really like the site. I have a question about the subwoofer it's in and open room about 15 X 20 i have hard wood floors. Should i put in on a carpet mat to help with the sound or leave on the hard wood floor ?

An Auralex Gramma is what you want They do wonders for your sub, regardless of floor type.

Thanks for the information i will check into this.

You can do a search on this forum, there are a number of threads with people's experience with them.

Just an fyi, hard wood floors and drywall are very reflective sound wise (ie hard surfaces), and with produce more ringing for your HT experience. Now this doesn't degrade your subwoofer sq as much as it becomes a problem for your speakers higher freq bouncing around and mucking up the sound.


You may want to consider some area rugs as well as some acoustic panels to tame your room down a bit... I personally don't care for a totally dead room, but a completely live isn't preferred either.... somewhere in the middle is yields a very nice response IMO.

They do wonders in what regards exactly??.. does it affect the sound quality?...cause all my set up is also on hard wood floor?

My setup was on concrete and it still made a very noticeable difference. It removes the immediate sympathetic resonance going into the floor so you only hear the sub, not the sub + the sub vibrating the floor. You still get floor and wall resonance at their resonant frequencies, but that isn't directly transmitted and those aren't as significant. I didn't think it would help with my sub on a concrete slab, but it cleaned the upper range of the sub up considerably. IMO, it should actually help even more with a suspended wood floor.

As other people are mentioning, carpet would do little for your sub, but you might want to consider it to help your LCR speakers by placing it in the path of the first reflection point between you and your speakers.

I just added an Auralex SubDude HD to my SVS PC-13 Ultra DSP subwoofer. It took me a while to figure out whether I could hear what the manufacturer's graphs suggested I would hear. Vibration transmission/creation into the floor is reduced, so I can no longer feel as much bass with my feet on my wood laminate floor. What I was very disappointed with before, especially considering how big the sub is, was the performance on bass sweeps in movies and music (e.g. demonstration of the Jericho in "Iron Man", 2Raumwohnung). It just did not grab me. Now those are a lot cleaner (less muddy) and I love how it sounds.

Would decoupling help if the sub is in a basement. I'd presume it wouldn't but i figured i'd ask.

Why would it not work? Basements can have different structural composition from the rest of your home (but not always), but the basic physical principals still apply. Isolation of a subwoofer from the structure it is sitting on helps greatly reduce the transmission of structure-borne noise in the frequency band where the platform performs well. Concrete surprisingly transmits a lot of sound. Concrete itself probably does not resonate when it is hit by sound waves, but it will transport them somewhere where they can find something to excite (e.g. subfloor, drywall, furniture).

Of course you still get the airborne noise which is what us bassheads are after (at least inside our listening room).

I am taking a spare over to a friend's to see whether we can notice a difference in his system too.
