I found some old speakers in the basement, hooked them up to my T amp (for the time being running off batteries, waiting for power adapter from ebay). They didnt sound half bad, and theyre free

BUT, the box has got to go... Local store has "hobby plates" as theyre called, wooden plates I use for everything. I was thinking of making a new box tohold both speakers in one, that goes at the bottom of my diy table (im short on space so have to use what i have).
Below is the table, then speaker, then a ms paint sketch of what i want to make, that is going in the free space on the table. Is there anything about the design that is gonna cost me the little audio quality i have?

EDIT:

after talking to dfkt, i came up with two other possible designs (a bit off scale as the two boxes take up allmost all the width but still):

gotta fit under the table on the pic, only place there's room. and they are too big to fit on top.

bah
of course, that design was way to big for the speakers.
got pissed and just made some boxes, if i really listen to music i use ehadphones anyways.
BUT dfkt said something about x-over circuit to feed right freqs to right speaker (as you see, old tweeters are gone, im getting some better ones to replace the ones on top too). Where can i get x-over? ebay had 0 hits on "x-over circuit" and "crossover circuit"
Oh, and i know that the design might cause loss of quality and blahblah, but its all about what i actually have room for more than what sounds best

partsexpress or make your own
what about the cross over that was in the old speaker?



only thing in there other than the driver and tweeter was a 47muf (or so) capacitor on one of the wires between tweeter and driver... nothing to get the higher freqs away from the driver
