    Ok, now I'm going to start asking bunch of stupid questions. :b
    So far looking through different final shots, I decided for the box design over the sonotub one, mainly because
    it seems to be easier to put plate amp inside
    and I could mask it with vase or something from my significant part. [​IMG]
    Would AVA250 give enough power to drive Tempest in the sealed enclose or I have to go ported?
    Is it ok to make box sub down firing?

    Go to the Adire site and look at the Tempest sealed applications page. They spacifically suggest an enclosure for down firing designs and I believe the AVA250 has enough power to get the driver to xmax.

    Rudy,

    Where's the picture of the whole/finished/completed sub?

    It's not veneered yet, too cold outside for that, and I have no interior workspace [​IMG]

    don't recall the model exactly, but 250 watts will drive a sealed tempest pretty close to xmax.
    i'm driving mine with 200watts and i have no complaints.
    here's my sealed tempest.
    in retrospect, now way too many mushy pix, just jump to the last one or two shots for a completed view. when i get around to it i'm going to update my site with clio measurements. (3-4 weeks) i'll post when i get the measurements completed.

    Thanks,

    What about ported design how many watts do I need for that?

    Actually, is it possible to drive something using amplifier integrated into H/K 520? I don't have center channel anyway, so it gives me free 75W line.

    That's what I'm trying to figure out: I have 24"d x 18"h sealed sonotube (to hide under the table [​IMG] )which gives me ~ 4.7cft ~130L. I use, lets say 1 Tempest.
    Now I have 3 types of amplification:
    1) 75W from my receiver
    2) 200W from my old stereo Nikko NR-500
    2) 250W from PE 794
    3) 850W from Nady
    What will be the difference?
    If you say that 250W drives Tempest near xmax, what will happen when I tripple the power up to spec-maximum?
