6 Sub Blow Through

[Mason Poston]

Looking to get some outside opinions on box type and design. I'm going to be running 6 NVX VS 15 on two Rockford Fosgate Punch 1000s (for now two, three later) and looking for opinions on what type of box to build. A 4th order is an option ive considered but I dont want to do a bandpass.. i want to do ported. Anyone have any ideas of how I can properly design a box for 6 15s in a ported box? Box is going in an Avalanche bed. Rough but close dimensions are like 49x19x50 i think. Not looking for someone to design the mathematics but simply throw ideas out on best way to place the subs and port for a ported box design! Looking to tune around 30 hz.. not looking for spl meter but simply murder lows. Thanks in advance!

may change my mind about the 6 NVX VS series.. idk what i want to run.. no more than $150 per sub.. decision is tough

Not enough room, and think about it- you will likely have 3 15s on each side of your enclosure (all side by side). That is 45 inches in length all in subs which leaves you with 5 inches between them all including the sides of your box. --15(sub)+15(sub)+15(sub)--

I would definitely do a bandpass if doing a blowthrough

heres a design for 3 fi audio SP4 15's in a 4th order specifically for an avalanche

of course you will need $600 per sub with another $2,000 in batteries and another $2,000 in amps

You could probably do 4 15 in a 4th order bandpass with those dimensions, that leave little extra room for spending on subs.which would work better for you . I know it's not what you want.may I ask why your not wanting to do a 4th order ?

[Mason Poston]

Well i have built a 4th order for 2 15s before and i just wasnt as satisfied with the output as i was with another ported box built for the same subs.. im not completely agsinst 4th orders but i believe thats going to be the smartest and most logical thing to do. What ratio? 3 or 4:1? instead of the VS series ive now decided to run the VC series NVX

[dolarbilz]

I can't say anything on the two other systems you had , lots of variables.do you design your own boxs? If so maybe you need some help with that.ratio's are not everything in a 4th order design either.cause I've seen and built 4th's where there's more sealed chamber than ported chamber.really depends on sub.and no I don't design for others.

[Mason Poston]

I do design my own and have been really successful with them so far. Last enclosure was for a PSi platform 3 and metered 140.5 @ 29 hz on half wattage of what the sub should be getting. But that was in a ported box and I really like the way it sounded just wasnt loud enough. Im just not as familiar with a 4th design to make it sound exactly what im looking for.

Im sure there are some people on here that can help you with a design
