Partly a theoretical question again
I was trying to accumulate 6 big woofers to make a large 3-Way box with one of the woofers rear firing for baffle step compensation
I only managed to buy 4 of them before they sold out
Typical cheap generic 8R woofer tho Fs around 30hz and 0.56 Qts
how important is it to have the rear BS woofer the same as the ones firing to the front?
So long as the third woofer was "similar" would it make much difference/
Secondly does that rear fill-in woofer actually need to be cut off or can it run full range?
My little Vifa mid-woofers probably won't sell in the trading post section so this would be a project to make use of them
If I make these there will be no fancy box work or anything. just a big monkey coffin.
I do mean big, the Vas on these woofers is probably around 2/300 litres I have the specs hidden somewhere tho

Why not just one forward and one rear firing for force cancellation? I would say you wanna filter the rear woofer.
Mainly because it's an aesthetic for me, dual mids in MTM just look better if you can see the dual woofers and partly for power handling We like our party music a little on the louder side
Totally wrong !
See one approach :

and many other threads that explore more specific branches such as cabinet construction
...well, there are many threads on DIY audio forum !
Aestethics is well considered but first : form follows function

WAF comes first for these Cost is important and second Fidelity comes third
Budget allows for bare monkey coffins but no frills allowed, SWMBO must be obeyed on this one if I'm going to be allowed to play with speakers as well as ski this winter
Using stuff on the shelf is a "MUST DO" so no running around getting parts etc NOT allowed so near enough is going to be good enough.
I am however needing to know if I can get away with a woofer that is within 30% of the parameters of the other two in each box

Moondog,
Have a look at post #7 here for how Thorsten uses two different woofers:

Works well if they're "similar"
cheers

A single woofer will rear fire at some lower frequency and to some degree it makes no difference whether you do traditional compensation, make a 2.5 way or use a rear mounted woofer. In each case you transition to full space radiation at some frequency.
