    Ok well here are the factors involved in this and this is my first time EVER doing anything like this..and it's good to note that i am a total newbie to HT's in general[​IMG]

    Ok i was thinking of doing a Shiva Driver (not sure on size) and a PE 250 amp. In a vented design.
    Room is 6000 sq ft 1 opening and it will be used in a 75% HT set up.

    Should i go sonotube or box, also i was thinking of a pyramid design since i am very egyptian themed and would like to keep that if possible but it's not a requirement.

    I tried reading the shiva build sheet thing and well it totally confused me...lol
    I need to figure out
    A. How big it has to be.
    B. How to vent it and where
    C. Size of Driver

    All in all i am looking for good deep base with out spending a whloe lot...i figure in all this should run me about 300.00 (thanks GeoffM for your help!)


    Thanks all in Advance!!!

    Well Dave, you have A LOT of area to fill with bass which makes getting the high SPL readings difficult.

    Just to make sure we're all on the same page here, is your room really 6000 square feet? That's more than 3.5 times bigger than my whole house, and I feel my EBS shiva isn't quite enough for my living room. [​IMG]

    Either you're dealing with a huge commercial type space, or you meant 600. If you meant 600, a shiva will be good. I bought my Shiva from Kyle... he's a pleasure to work with!!

    Here are two links that will help you.

    A pyramid shaped sub would be way cool.

    Hi Dave,

    In a room as large as yours, you might want to consider the Adire Audio Tempest. It's only $25 more and is capable of appx 40% more output.

    Adire Audio has suggest vented applications for this sub as well on their site.

    He probably meant cubic feet instead of square feet which is still quite large. That would be like a room 20'w x 30'L x 10'H.

    Ok my bad yes i meant cubic feet not sq...lol sorry.
    Man if my rrom was that big i would be making a bit bigger box..
    ok i made some really huge miscalc somewhere last night and got the real measuements for my room.

    11'5"W x 14'L x 8'H is 1288 cubic feet?

    If so lol i was more than a bit off...LOL

    Anywho will my set up be ok for a room this size?

    A Shiva should work quite well in a 12x14x8 room.

    Ok well i figured out the Pyramid dimensions..if i go that route. Dimensions will be 27" X 27" x 24" (base X2 , side x4 no top total volume is 3.37 CF , only thing thats giving me some issue is how to brace it.

    Another idea my buddy had was to make the standard box for the sub and make little pyramid's for the fronts and rears.

    I will have to figure out how big they have to be and all...but i may go this route[​IMG]
