    I'm looking to build a sealed or vented cube subwoofer. What driver could I use that would work very well with this? Would the Tempest be a good choice? Blueprint 1503?? How large of a box would I need? The HE15 would be a choice, but its expensive and I'm trying to see if I could go another route. I would be powering this cube with one channel of my Samson S700, so 350w RMS. Ideas?

    No we cannot help you, nobody here has any interest at all in subwoofers , so please go away and never come back. [​IMG]
    No need to read any further as I am going to tell you how to build a great subwoofer that will be good for HT and music use. Now adhere to these plans exactly or your performance will suffer.
    Buy a Tempest driver and put it in a 12cuft ID box made of 3/4" Baltic Birch plywood and brace it heavily you must account for the braces , port and driver as they take away from the volume of the box , use a single 8" PVC pipe port , we will get the exact length for you once you get the box built it will be tuned to 17Hz +/- 1Hz . DO NOT COMPROMISE THE BOX SIZE OR PORT SIZE OR YOUR PERFORMANCE WILL SUFFER.
    That's it , now get building! [​IMG]

    Dang, thats pretty awesome. I wonder how it would work if the tempest was front firing? Any ideas for that?

    What would the difference be in sound and freq. between the front firing and the down firing?

    Scott, we know nothing of subwoofers, but... Here it is. 6.2 ft^3 ported sonosub, Adire Tempest driver, tuned to 17.5 Hz with AVA250 amp mounted on the side. It has dropped many a jaw. Do it.

    Scott,
    If you build one of these suggestions and you ever run into a kid named Brian from MD... DON'T invite him to hear your sub. He'll likely whip out a gun and shoot himself right in the middle of your living room.... [​IMG]
    And James W... who are you to tell anyone about these new fangled subs... You obviously don't have a clue...
    Seriously,,, Scott,
    I've heard both Shiva and Tempest based subs at Patman's and you won't be sorry. They are simply awesome.

    Hank, do you think that your sub would work well with 350w RMS? Thats what I'll be putting into whatever I build. Im almost dead set on building exactly what youve made (of course mine would look different). Do you guys think this would compliment my 20-39 very well? Hank do you have any instructions for that enclosure?

    Scott, since mine works More than well with the Adire AVA250 (250 watts), it would work Exceedingly well with with 350 watts. Mine is in a large room with a 2-story ceiling and openings into other rooms and is plenty loud.
    I recommend the AVA250 as it has the usual 35-40 Hz boost circuitry defeated. No drawings for mine, but I do have a couple of sketches, including a trick to cut the two curved amp enclosure pieces.

    Hank is yours sealed or ported? I cant tell with that shark on the top of it....=). I know everyone has seen jameW's pig. Well, what if I built half one, i.e. used only one driver? How would that work out?
