is it advisable to put my four Tsw1000c pioneer subs into a 3.5 cubit ported box all in a common chamber ? this is the reccomendation i got but im not all to sure about the common chamber thing. the sheet says a good ported box for these things is something like .6 cubic feet.

 

Providing the box / port is tuned properly you should have no problem.. My 2 JL's are in a 5.12 Cubic box single common chamber tuned to roughly 35hz.. they call for a 1.75-2.25 box per sub.

But im not the expert, lets hear what other have to say..

 

it wont matter as long as the subs are all the same

 

Also, if one sub blows, it will act like passive radiator, which also sucks.

 

hrmm. good points. i think i'll risk it.. seeing as t hough they are only getting 250 watts of clean power. that is. i never really push'em to any limit
it dont sound right, i turn it down.

In the "Outlaw SPL" competition last Sunday, where they stick the mike right in the port or in front of your sub box, my single sub (in a sealed 1 cu. ft. box) hit 152.7db, beating Vision's own and Autotemp's own entries, that had 4 subs in common chamber boxes.

Cool eh?

 

Not true (atleast in my case). My wife runs a single RF HE2 10" and blew it. I replaced it with one of my 10" memphis' and used hers as a passive radiator in a common chamber duel 10 setup. I barely notice a difference. Quite surprising.

 

I have a problem. I sort of am indecisive about using three or four subs for space sake. I cannot find a program that will have my subs specs on its database. they are pioneer tsw1000c nickel plate subs. Just wondering what program would have it ? i tried winisd but i think they are to old for it.. at least there is nothing in the pioneer section . someone gave me specs for a box using a program called bass box i belive. i cant find that program. anyone got a link to it ?
