Default I couldn't bear to throw them away...

so I rounded up all the crappy drivers I had and made this OB:

All the drivers except the 12" unit were scavenged from what neihbours had thrown out, The 6" units & Tweeter are old Magnavox units, had to cut off the dust caps, they'd been poked in, the 10" unit is a Taiwanese,no name, 12" is a hi-Q Jaycar driver ~AUD50. The wood is some old cupboard doors.

Sound - pretty good, doesn't need much low EQ, very good on vocals, but some stridency in the upper mids makes it unlistenable on Heavy Rock. Considering the xover is only 2 caps (jeez I'm cheap...) (one for the tweet, 1 across the parallelled woofers which are in series with the mids, which probably can't handle more than 5-10 watts) that's not too bad.
Just need to refine the xover & pretty them up

eexcelent, i love it! i like your alon type open baffle shape
diy at its best
use the inductors for woofers, that will improve the midrange a bit
otherwise not much else for crossover is needed

Default finally got around to it...

added a 3mH choke across the mid drivers (this is a series xover)... now they sound awesome, really smooth all the way down on double bass, I add just a touch of lows on the tone control to get overkill kick drum on modern music (Black eyed peas etc), and a touch of highs to make up for the inefficient tweeters (they're really old, with tiny magnets)

Even better - WAF is 100%, the missus loves them...

It's nice to use up some old stuff and have it sound good isn't it?

One question: Is that really all of your old crappy stuff?

i like your comment about rock. I think rock is a really good demo of how good yoru system is, expecially when you crank it up. I know lots of beautiful, soft, acoustic jazz stuff which will float you away on even crappy speakers, but try playing metallica... Most likely not gonna happen.

... and in the garage, and in the workshop....:-)
(just call me magpie)

Re: Rock, I've haven't tried the System of a Down CD yet, I suspect I may need to zobel the mids to tame the stridency,
but I ususally play the Heavy stuff on my garage system so I don't annoy the neighbours too much - but much to my surprise, the OB bass can do that when wound up too....
