help with 10 sealed enclosure for SQ
hey,
i've been doing some research.. but I cant seem to understand any of it..
i just picked up a 10 inch clarion signature series sub and the specs say that I need a 0.5 cubic foot box.. tuned to 45.22Hz..
im pretty lost.. i want to get the best possible sound quality out of it... if i just build a box with an internal volume of 0.5 cubic feet.. will i get the same sound quality i would if i could figure out what all these numbers mean: (they seem to be the important ones from.. the very limited amount of info i could understand)
Qtc - 0.721
F3 - 45.22Hz
Qts - 0.64
Vas - 0.533/15.1 (Ft3/Litre)
.. am i just completely over thinking this?
does anyone have any experience building subwoofer enclosure boxes who can offer some sort of explaination?

In the correct ported enclosure that sub will rock you all right.....the extra volume from the port is a nice bonus......
You will need around 5-600w at 2ohms to get it moving......it will take 1,000 if you must.....
What brand, model, etc. vehicle is this for?

I hope that amp can run at 2ohms; It should give you more power then 450WRMS (if It can run at 2ohms)
The DVC (if you didn't know) means Dual Voice coil. So you have 4 terminals each pair has an impedance of 4ohms. To get the most out of it I would suggest running the pair (of terminals) in series. This would give you maximum power at a final imedance of 2 ohms.
Other wise your going to have to run it at 8ohms which would give you a poor result.

it gives me 700W rms @ 2 ohms.. i'll be sure to use that diagram.. thanks! ..
i've been messing aroudn with this program called bassbox.. and it doesnt seem like there would be a huge diff. in sound levels with differerent sizes of sealed boxes.. the only difference with ported boxes... is that the lower ranges seem to get a boost..
.. does the results the program gave me translate into real life preformance too? is that tha major difference between porter and sealed boxes?

Be sure to have everything set properly. Including "box volume displacement by the driver", if your playing with ported designs you'll notice that it removes Vb for extra wood that you wouldn't use on slot port in the parts list. To accommodate for this I usually split the wood difference in half and enter that into the "box volume displacement by the port - area B:" eg. for .75 wood enter .375.
Then you still need to use the "Box volume displacement by misc. objects" area to choose Shape: Square, prism, and enter the dimensions from the parts list for the skinny sides of the port and click on the "Add to Vb". If you double the thickness, you'll only need to account for it once. This will make the interior air space correct.
Also, make sure BB6P has your proper specs. Go over them and change any that aren't exact. There will also be times the port length will freeze (and change color) ... just clear one of the dimensions and re-enter it will adjust.
