Compact bookshelf design recommendation?

[kenny12]

I'm pretty new to speaker building, but I'm looking to build a set of bookshelfs for my computer, size is important and I would like it to be as small as possible.

I live in Australia so that may limit me on some driver choices. Budget would be about $250 dollars and I'm willing to pair the speakers with a small subwoofer (recommendations)?

I'm pretty familiar with electronics so wireing, building will not be a problem.

I plan on powering these with a tamp, although i could design my own amp...... but thats another thread.

How small is small?

Without knowing that, i can suggest the uFonken since you have the budget. If those are USD you could even afford the tricked out drivers.

hm.. say around 20cm tall and 15cm wide

mFonken is about 29x17, uFonken 22x13

The 2 smaller ones

You could build something around this driver.

With a simple notch and a mild BSC they sound clean and go surprisingly low for it's size.

It would work sealed in the same size box as the mFonken, but with a 2 dB peak at ~150 Hz. Given desktop use that would probably get exaggrated. And it would need 4x the power over the mFonken for the same levels. The drivers are about half as much thou (both still well less than his budget -- at least in North America). I know the mFonken driver is available in Oz, and making the driver a lot better is pretty well documented.

Hmmmm, what about putting 4 of Daytons per side at approximately $200 total? It would give you much higher efficiency, power handling and lower distortions. Also a line array vertical of axis response character. I'd go ported as well.
Just an idea.

Qts is .87?

Use this to flatten the peak:

He is looking for a box that is smaller than a single one will fit in...

Mark Audio CHR-70 & Alpair 6 would probably fit the bill box size wise. About the same efficiency as the Dayton.

LOL on the hammer!

The t-amp and the fostex 127e work great together IMO.
