Cleaning out the closet and found these!

[O_ROD]

Doing a little cleaning and way back in the closet I found a pair of AudioPulse 1035's made in the 80's that were my fathers. Naturally I pulled them out and started playing with them. They are a 3 way with a rather large tweeter, 4" midbass and 10" woofer. What's more interesting is the tweet has a 1st order at 13500Hz. The mid has a 3500Hz Xover. And as for the woofer, well it had none! It played full range!?! Soo, I played the speaker without the woofer connected out of curiosity and it sounded horrid. Very tinny sound and harsh with no detail. I found that the majority of the sound actually came from the woofer! Now the speaker all together sounds OK, but nothing special. I know these are cheap speakers but no xover on the low end? I looked deeper into the woofers and found the T/S parameters:

I'm looking to maybe do "something" with these woofers instead of chucking them in the garbage. The specs show it would need a very large box tuned low, or maybe baffled? What would you guys do?

Interested to hear your takes on these!

And as for the woofer, well it had none!

The EPI 100 had this arrangement. One Cap on the tweeter, nothing on the woofer. The idea was to use the natural 2 order acoustic roll off, plus the voice coil inductance as the crossover.
Not a lot of options where to crossover with this method.
It goes without saying that metal cone drivers need not apply.
