i need to make a box with 3 boxex in it
There are three separate enclosures: V1, V2 and V3. The subs are mounted on the wall separating V2 and V1, firing into V1. The first port P1, couples enclosure V1 and V3 cutting through V2. Port P2 fires from V2 into V3. Port P3 fires from V3 to the outside world.

Volume V1: .74 cubic feet
Volume V2: 2.78 cubic feet
Volume V3: 5.92 cubic feet

Port P1: 71.57Hz - 6.00 inches / 4 inch diameter
Port P2: 19Hz - 16.78 inches / 3 inch diameter
Port P3: 36.87Hz - 1.28 inches / 4 inch diameter

can someone make a 3d pic of this in a box planner for me ?
i can not go over 24"H or 38w or 44L

 

you should check your pm's i replyed to the one you sent

and what kind of box are you trying to make ^^^ everytime i read it i get more confused

 

^^^ was going to ask the same thing

Mark

 

this is for spl is that wath you are thinking about it does not need to be that hz

 

sounds like a Bose Acoustimass sub enclosure..


and... yep: http://www.bose.com/popup/tech_detai...coustimass.jsp

I would keep looking..

 

yes that is it but how do you work it out ?

 

These fancey boxes from blose and the like are generally made to get loud at a few frequencies with wimpy drivers.. lol..

when properly designed and implemented in a system they can work..... but considering you can build a ported box that can cover the entire bandwidth you want; it is just the way to go....

multi KW amplifiers and high excursion bass drivers are relativley inexpensive so output levels shouln't be a concearn...



Seems like you want to build these boxes just to experiment and play around for yourself.. but getting phase and transient response that is all over the place for a gain in output is not the way IMO...

You want to know HOW to design it or you just want the answers?

Well I'm not supplying either

Build a simple vented box - you will be happier.

 

O thank you !
