Hi Everyone
First of all I want to thank everyone here as I have spent numerous hours of drooling over your HTs and excellent building and planning skills. You have inspired me to no end and I thank you for that. So after months of convincing my wife that dedicated HT is needed in our house more than anything else, I have pondered and pondered on what, where and how. So here is my idea.....Oh yeah and Please provide constructive criticism.

I will split my build with the room first and then worry about the equipment later. I have JBL speakers, Yamaha receiver but I think I may have to update pretty much everything when the budget allows.

So I am planning on building a Cave…literally. I have a perfect 13x13 squared room which is not ideal but it is what I have to work with. Walls are all concrete except one and it cannot be moved. I have framed the walls and insulated it so far. Pics are to follow. In my spare time I build Styrofoam backgrounds for aquariums to make them look like natural habitats, rocks, mountain sides…..so I wondered if I could do the same but on a larger scale and pretty much for nothing cost wise.

I have been collecting packing Styrofoam from big box stores and have accumulated quite a bit. For the last couple of months I have been quite often hovering in the neighborhood appliance stores foraging their Styrofoam.

I will be gorilla gluing it to the wall with all kinds of thicknesses, shapes and then fill in the gaps with crack foam filler. Once all dry I will start carving with an electric chain saw, carving knives etc. Once carved to a desired look, I will then coat everything with cement with a fortifier which will make it stick. Cement will basically be watered down to a butter like consistency and brushed on several coats and then once hardened play with some oxides to get a desired color. I have done 100s of these for aquariums and have made some pretty amazing stuff so I figure it should not be too hard to do this on a bigger scale. I think the challenge that I want to achieve here is a cheap, environmentally safe built HT. But Really….cheap is key here.

Alright so If you look on the net for a batcave HT, and I am sure most of have, that is pretty much the look that I am going for in terms of the walls.

Let me know what you guys think and again constructive hints are always welcomed. Thanks for letting me be part of this awesome community.

Cheers.

Welcome!

One thing that immediately comes to mind is that while that might give a pleasing aesthetic, it could be hell on acoustics.

Ok and that is what I was thinking too however I went to a local av specialist and they said that with the protrusions and irregularites that I will have in my wall that that is exactly what you would want to break up the acoustics.

I am attaching couple of pics for reference only of the look that I am going for. You can see the shape of the walls that I will be carving and my understanding is that this is exactly what one would want re; acoustics. I could be off to lunch though so please let me know why such a design of walls would not be conducive to a acoustically sound environment. In the batcave pic I don't see any wall treatments......Any help would be appreciated. Cheers bat-cave-home-theater.jpeg 168k .jpeg file
