831857 box

i was wondering how i would find the volume that the speaker takes up in the box.
and i was thinking of using a 140L box tuned to 25hz do u think this would be be any good.

thanks

waaaaay too big for that driver
cut it back to something like 25L or up to 40L maybe.
But 140L is too big. You will have a fridge for small drivers, and your transient response will be shot. tune closer to its fs, 40Hz region would be fine. not much lower. If you intend on using a sub also then just seal them in 15L boxes. as for how much volume the speaker takes up dont worry, it wont affect it, not unless the box is tiny. even if the driver was huge it would not change the tuning more than a fraction of a decibel and you wont notice this at all.

what the hell are u on michael maby u read wrong im using the PEERLESS 831857 the data sheet recomends a 90 - 180L box.
it is 12" and u recomended about 180 to me on msn.

oh hi ben, i wasnt reading right i thought it was an 850467 for some odd reason, there was another thread on this driver... stupid me, yeah your idea is fine, 140 wil be fine and 25hz is good.
just build the darn thing already, i can coach you through it in messenger when you are ready. talk to you later ben

how important do u think the bracing will be if i use a 545 X 545 X 545mm box using 16mm mdf.

The more bracing, the better. You just gotta make sure it doesn't take up too much interior volume.
