Mini DIY

I actually calculate slightly less/equal volume for the 4406, so I suggest we just go with the 704 cu. in. of the L20T.

'Just waiting for the rain to stop so I can clean out some space and assemble the drill press. It's really too crowded for me to do without being able to shift stuff around outside while making room.

Hey when you guys are done please put together a picture thread of your Minis... most of us are only here for the pretty pictures.

Heh. We'll look forward to seein' your machined MDF curved-cabinet mini version there....

[It's time you replaced your Brand-X rear surrounds with something neato DIY, anyway....]

Here is the foilcal I plan on using.
I'm printing the image at 1/3 scale on the photo printer

All done, but grills

Here is the crossover I went with

I started off with a 1mh coil for the woofer, but this caused more of a dip around the 3khz point, so I removed and uncoiled it down to about .8.
The Lpad is at about the -7db point. It might be a good idea to modify the fixed resistors to trim this a bit more.

Listening to the babies it is no surprise that they don't fill up the room with sound like their parents. But they sound quit good as a near field monitor.

SWEEEEEET!!!!

Way kool! What was the process for the foilcal once you printed it? Are you interested in printing a couple more? Zilch and I would likely be interested.

JohnW,

Your mini's are outstanding! A question on your 4425's - Are those also DIY units since there are no foilcals or level adustments?

Regards,

I found a matte finish photo paper that seemed to work good. I printed it on the photo paper and once printed it was a little too dull. I then sprayed it a couple coats of clear lacquer and it came out about right.
I would be glad to work up a couple more if you would like. Just let me know the dimensions and if you would like any changes to the layout.

The 4425 are copies too, built with info from the Quick and Dirty thread. Here is the original thread of these:
