    I'm building 2 sonosubs with 15" tempest drivers. They will be powered by a samson s1000 (Each sub will get 500 watts). The theater is 18x28x9 feet. The theater is only for movies and no real concern or want for music. I do want insane amounts of bass, no constraints on size or foot print but it sure would be easy to be able to get 2 subs out of a 12 foot length (18 or 24) it doesn't matter. My wife is fine with whatever I do.

    I started thinking though, would their be any advantage to making 2 different subs. Maybe one sealed and one ported, or 2 ported ones tuned to different frequencies. I was wondering if anyone wanted to chime in about their ideas for this type of set up.

    I've built sub boxes before for cars but this is my first for home. I tried messing with lspcad but it seems over my head.

    thanks,

    Scott

    Make 2 identical subs. Do not mix a ported and sealed one, or mix a ported ones that are ported at different frequencies.

    In My Very Humble Opinion,

    Build 4 sealed Tempests. Look around this forum and you'll see that "upgrade-itis" is a very common thing. Since the all-important Wife Acceptance Factor is no problem here, rather than 2 huge ported boxes, IMVHO, I'd go for 4 sealed Tempests. 18x28 is a fairly large room, and its always more fun to have to turn down the bass than wish you'd built more.

    Humbly submitted,

    thanks for the great responses,

    Now some more questions:

    Mike: So what volume for a sealed box would you go for if you had only 2 tempest for now? (Up grade to 4 later on down the road or even maybe a couple of 18" [​IMG])


    Or maybe build these 2 as ported with the intent of building 2 more and run them at half volume from the amp? Maybe this is a stupid question, but by researching these boxes it appears as though the lower the port tune the more protected the driver is at low frequency. With the freedom I have I can build something 6-7 feet tall and 30" [​IMG] If I went with a ported design what frequency would be the best to tune to port to?

    These are the two "twins" that I built for Jeremy Santos the guy in the picture and they're quite impressive.

    Nice Subs.. What are those things infront of the sub?

    Well I've narrowed it down to either the sealed design found in the adire audio booklet on tempest boxs (the low q 230L one) and the ported one (EBS 340L tuned to 15.8). Anyone see any advantages or disadvantages to these designs with my samson?
