New Build - The Mini J Two-way Bookshelf Speakers (and they're purple)

Hey everybody, it's been a while since I've posted anything on the forum so I decided to share my most recent speaker project. This was a really quick project, from concept to design to final build was less than two weeks so I didn't have a lot of time to bounce ideas off of my fellow speaker builders. Forgive me for not allowing everyone to share in the creative process of DIY. I know that's half the fun! Nonetheless, I also know everyone loves build pics and I took a whole bunch. In summary this is basically an inexpensive 2-way bookshelf speaker made with a Dayton Audio Designer Series 5" woofer and Vifa DX25TG59 1" dome tweeter. Cabinet is about 5L tuned to 51 Hz. They were a birthday present for my daughter so without telling her what I was making her I had her pick out a color she liked for "something" I was making her and they ended up dark purple! Needless to say, my first purple speaker. Anyway, they turned out great and sound fantastic, to me. I used a lot of the typical free modeling tools out there for box volume calculation (Unibox), crossover design (PCD7) and of course REW for measurement! What ever would I do without all these great speaker building tools?

And with that, I'll let the pics do the talking. Enjoy!

That is a very acceptable response from such a small unit. Well done!

Silence is golden but duct tape is silver.

Looks super Well done!

I wonder if you could fix some of the raggedness and peaking in the midrange response by countersinking the woofer as well, along with a rear chamfer for better airflow. Doesn't look like the poor guy has any room to breathe back there.

You would lose the overlap, but with such a high crossover point I'm guessing you will still get accurate summing.

However, it would mean a rework and that is probably not a good thing.

Very nice work.

How is it going with the impedance measurements for speakers?

I've been having a few problems:

Pretty sweet build, love the color. Why is your microphone so close when measuring ?

Very nice small monitor for your daughter.
Wish I'd had some nice speakers like those at that age.

What do you think about the DX25 tweeter?

Very nice little build!

Looked good in PCD and then your measurements prove it. Great work.
