    Nice little speakers and a great paint job. I'm sure your daughter loves them. Now,... on to the subwoofer.

    I didn't know that mids could sparkle, thought that was reserved for the treble! :D
    These came out awesome!

    Anyways, enjoy.

    I have the hiwave but not the tweeters, but I can probably take a stab at a thin tower in the next few weeks... I have a gift project of similar dimensions coming up, and can clamp on a temporary baffle and run it fullrange.

    Great work Tyger! The Mariposa's are really small. They make that keyboard look like it belongs to Andre the Giant. :p

    For giggles, here's two pics some may enjoy:

    First here's the final impedance and phase profile of the completed speaker:

    All,

    I thought I'd take a moment so show some more pics that I've generated as I'm buttoning these up. First, here's a pic of the finalized crossover, built onto an ultra-small radioshack perf-board (pn 276-148). You'll note that I used some Erse components in here rather than the PE components, but that shouldn't make any difference. I just used what I had on hand.

    I ended up adding in some male spade connectors in order to connect the speakers and terminals. Here's how I did that:

    I screwed the crossover down right behind the tweeter. Because the front baffle is glued and nailed in, I had to make sure that the screw holes to mount the crossover lined up with the tweeter and subwoofer cutouts. This is to allow a long screwdriver to get in there and attach the PCB to the back panel:

    With regards to the stuffing, here's a relative picture of just how much stuffing got added to the box:

    When everything is shoved in, the stuffing is hanging outside the box, and it will force the woofer out of the hole if the woofer is not screwed in:

    I like it. The Choti HT that i did is also surprising just how small it ends up being, and iirc it is an inch bigger in one direction, and 1/2 inch in another than the PE knock down cabinet. These are even smaller.

    I was also impressed with the nd16fa. The amount of detail that it is able to pull is way more than a $10 (at the time) tweeter should.
