Random 4th Order 8" Build


Recommended Posts

Had some scrap MDF laying around in the garage, and my 8" DC LVL2 figured I'd play around with build a 4th order. No real plans for this other than the sake of something to do...it may end up being a test bench setup down the road if I get a battery and charger for cheap. Pictures are random cause I wasn't really planning on doing much but here ya go

Voice coils switchable from 2 or 8 ohm so I can run it off an amp or in my house

i pulled out my dick in class many of times and had it shown. get over it bitch...stupid open legged hairy beavered bitch...

going over rms = smaller box, under rms = bigger box...

Low voltage doesn't blow amps. That's a myth.

A router that does the sub holes makes rounded edges also?

:good:

there is some VERY hard headed people out there. Anyone who says a DD-1 isnt necessary is also saying an O-scope isnt necessary. Anyone who says an O-scope IN THE MINIMUM isnt necessary, is a noob. Forget the DD-1 for a minute, any reputable installer will at LEAST use an O-scope. Those guys in that thread are clowns. Hard headed clowns.

Looks good I also wana try a 4th order with some scraps I have around but don't know the 1st thing in designing one

So I gotta research a lot.

Looking good tho

They aren't too difficult, just consider it a sealed box inside a ported box, gotta figure out what ratio of sealed to ported works best for your woofer, but after that it's easy.

:good:

Thank you

Very nice mate, tuned in :)

Thanks!

Fuck the box...

Nice damn saw.

Not too bad for my first table saw :pardon:

Ray took the words right outta my mouth. Those saws are nice!

I love it, it's the reason I'm out building boxes for fun, can't just let a saw stop sit around 8)
