If you like her, then I suggest that you watch her in her birthday suit in Original Sin with Antonio Banderas.

Are you using your current setup for the sound? If so, there is not front sound stage

I was just doing my job. After all, this is the riser thread.

I will ban myself after this comment.

Maybe a small sat system

I don't use it enough to warrant that ~ Especially when the money could be spent on improving the HT

You mean to tell me with all that beautiful equipment you are lowering you're standards and using the TV speakers

What's the reason you guys decided to go with that type of foam under the riser?

Big Daddy's advise , That's all I needed !

Big Daddy knows more about sound , sound waves , speakers , subwoofers , Gear (AVR / amps) then anyone else on the forum that I have seen . So his ideas & suggestions tend to be as good as gold with me .

Just read his stickies

[kareface]

At the db levels most people watch movies at and the frequency range that subs produce, that style of foam will usually do little if anything to reduce vertical node energy. Even the pressure equalization bass traps that come in the subtraps mentioned in the first post, which are much more LF effective then foam for their size are only rated down to 70hz for an 8' ceiling (which is the US average according to bd). My subs aren't even crossed over till 60 & my ceilings are shorter then that even. I'm looking to build a pair of risers that come up about 18 inches. The problem I've run into is how to best dampen the excess node energy. Especially for LF, density matters for mass dampening. It just doesn't seem like something that would be as effective. I have used high density foams for STC dampening before, but the wall mart stuff looks to have a much lower pcf then that. Correct me if I'm wrong here.

big daddy. what is your opinion on my riser? pics are in my ht gallery. i think it sounds/looks good this way. are there any benefits to having a wooden board or using different foam or another setup that could potentially make it sound better? should i stack it up higher or would this be ok permanently? thanks

The riser looks good. It is possible that if you raise the height of the riser, you may get improved results. In a typical room, you can raise the height up to a couple of feet. See Posts #2 & #3 of this thread for explanation.

High density foam can have isolation and absorption properties it is also inexpensive and easy to find. The goal is to minimizing the amount of energy transferring into the floor and then other objects in the room.
