Unexpected success !

As anyone that has read any of my posts might have gathered by now........I'm a full fledged tweaker.
Two months ago I retired from guitar repair and being a man without a car in the dead of winter, I don't go out much, so it was time to start tweaking !
I spent the whole summer picking up any cheap speakers at tag sales that I could fit on my motorcycle and had plenty of fodder to work with.
I started this project out with a pair of what must have been rear speakers for an 80's Zenith stereo system.
They're made from a thick inert plastic and shaped like leaned over trapazoids, with a full range 4" speaker angled slightly upwards.
The drivers however were 16 Ohm, so I replaced them with a pair of heavy magnet Minimus 7 woofers, that I doped with the thinnest SuperGlue that I had.
On top of these cabinets, I screwed on a couple of Cambridge Audio mini computer speaker enclosures (think Bose cubes) in a mirror image offset placement.
They have rubber washers that allow them to swivel.
I then gutted them and installed two polycarbonate 1" tweeters from a pair of Yamaha speakers that were given to me yesterday.
I also pilfered the two way crossovers from the Yamaha's, because they crossed at 5000Hz (12db), which is about what I guessed that my doped drivers were capable of covering.
The cabinets were stuffed with old fashioned fiberglass.
The first time I fired these babies up with some Steely Dan, I was flabbergasted !
They sounded better than my KEF Q10's !
After pointing the lower cases toward me and swivelling the tweeters slightly off axis outwardly...........it got even better.
By the time I matched the sub with them, I was in heaven !
All for the cost of 1 dollar. (what I paid for the Cambridge mini boxes)

I agree. I like hearing stories about minimal spending for good sound rather than large spending for great sound.
Im a bit of a tinkerer myself but I just don't have the room or time to build a set of Frankenstein speakers. Wish I did.Just a dude doing dude-ly things

Careful what you wish for... I seem to recall having an address that can get stuff passed along to you...

Looks like fun....!
You may want to read Dennis's Measurements and "Review" of the minimus 7, may give some insight into your project. (since you used that woofer)
