You continue to ignore what people who are educated in this matter are telling you, with absolutely ridiculous anecdotal evidence. It would be like me telling you the sun is actually only 30,000 miles away and refusing to believe all the scientific evidence that shows it's 93 million miles away. That is how mundane this conversation has become. You have a huge opportunity to learn here, but you think you are right and that's all that matters to you. That is what a mule is like. |

You really need to give up the fight there fella. It's now embarrassing to be you. Terrence makes a living working with sound. Do you? These audio principles are not really debatable. These are not theories or hypothesis; they're laws. |

If you take aa hardwood floor, in a hard room and place the sub in the middle, the characteristics are totally different if you cover the floor in broadloom and hide it in a corner. If you as well as he, believe that bass is totally non-directional... you are dead wrong. It is MORE non-directional than mids or highs but unless you're down to 20 or 18hz... most people I know agree that it is not totally non-directional despite what a course tells you. |

Again you have completely misunderstood or misconstrued everything that has been said here.

They don't want you to put your sub behind a wall anymore than your speaker. If you just want to cross it over at 30Hz, different story. They're writing manuals for joe schmoe who doesn't have a clue, not av-philes. Quote:

60Hz is bass and no it is not directional. Quote:
As for the anechoic chamber, what it does is shows you that the reasons why you "hear" these low frequencies you think you do with directionality has nothing to do with the actual sound, but everything else...because when you're in an anechoic chamber with no reflection points the subsonic bass cannot be placed. |

Distortion, suspension noise, port noise, and cabinet resonances occur at HIGHER frequencies than 80 Hz, increasing the mind's ability to locate where a subwoofer is located. That is one reason why we have downfiring subwoofers, so that a sub can fire down onto a carpet/throw rug and any rare noises from the driver can be absorbed by the carpet, and the non-directional characteristics of low frequency bass can be strengthened.

Sorry to bring up this old thread.
Curious if anyone has tried these on carpet/pad covered concrete floors. I am not so worried about improving the sub's sound as I am about my walls/room shaking. Especially at lower frequencies. Which I get a lot of in my current setup. Could the GRAMMA reduce this or eliminate it? I thought a concrete floor in combination with a think pad and carpet would be dense enough as hell to prevent any vibration issues. But I am learning as I read that concrete in some cases can be worse than hard wood floors. ![]() So I guess I want peoples opinion of whether or not it made a difference for them in a similar setup as mine. Let me know, thanks guys. |

I have Great grammas for my PBU's Size: 27” D x 20.5 " W x 22" H (w/o grill) , with the grill you can add couple more inches and they still fit perfectly on the pads.
As for the question above concerning th grammas on on carpet....I had mine on it for a short period, it did quell some fo the vibrations through out the house, but REW confirmed what I was feeling....the bass frequency was weaker....not sure if I have the graphs saved or not but there was a difference no doubt in my system. here in Italy I have both of my PBUS on grammas on tile floors....havent hooked them up yet.... |
