looking for some pointers
 

i have 3 V1065S4 Visonik 10's in a 37.5"x13.5"x14" (W,H,D) box with a divider between each sub, powered by a Bass Inferno 2000W amp.
now the specs say .5-1.0 cu ft, sealed or 2.25 cu ft vented. the max space i could go is 37.5x14x22 (W,H,D). i find certain songs they hit nice and hard and vibrate the crap out of everything then other songs i can barely hear any output from them. i think my enclosure is too small, or maybe i should go to a vented style port with only 2 subs.
any suggestions would be great

I don't know the model # of them, but I currently have 2 of the red visoniks 400wrms dual 4ohm coils with the big surrounds on them. We just threw these in the box I made for my "REAL" subs when one was being repaired. ( dust cap blew off of one of my Clarions) 1.0cu' each with a slot port tuned at 34.5hz and these things will tear the car apart. Hit 141.8 on music with a 2kw Hifonics amp on the termlab. If you have the same ones I would highly recommend a similar box. PM me and I will see if I can dig up the design for it. Pics of the box in question are here....

Your box is almost exactly 1cuft/sub right now.....you only have enough space to do 2 of them in a vented box......:dunno:

The drop in response at certain frequencies may be due to other factors......box location and system setup come to mind......:smokin:

10" subwoofer should not need over 1.5 cubic feet in a ported enclosure.

~ 3.75 cubic feet tuned @ 36hz using aeroports (or even PVC pipe)

Each port is 4" in diameter and 11.5" in length
Make sure each port is secured properly using something like PL Premium. You want to make sure they flex as little as possible and and air tight secured.

Top - 36"x18.5"
Bottom - 36"x18.5"
L Side - 17"x11.5"
R Side - 17"x11.5"
Front - 36"x11.5"
Back - 36"x11.5"

wow first off thanks every one for your responses

420guy i do like that box design, simple and to the point, and close to what i need is 35hz, yes the subs i have are 400w rms and the big magnets, but mine are single voice coil, i wouln't mind going a little bigget to maybe 1.2 or 1.5 cu ft per sub, at 35 Hz.

BigRedGuy, yes i am aware with vented i can fit 2 and well if it is way more efficent i shouldn't need the 3rd sub, i have considered my components i've played with the settings i got it sounding ok, but could be better lol

Jalat thanks for the design i will definently consider it as well, and yes i thought 2.45 cu ft seemed huge for a 10, because nobody made a box even close to being that big atleast i couldn't find one that's why i want to make my own

jalat, if you still have the design you did for my Clarion's would you post it up as well please. I have the same subs he has in my box now and they are doing awesome. 141.8 on music at the Kjohn show until they started smoking. OP DO NOT put a 2000 watt amp on a pair of these and you should be okay. LOL

Close but no cigar there bud.....:D.....the ones in your box are V106S4, his have fairly different T/S specs.....:smokin:

OP, if you want the specs for those subs PM me and I'll email 'em to you.

HTH
