LX mini inspired components

1)  < Inspired by www.LinkwitzLab.com > 
2)  Using the information Linkwitz has made available, I worked to understand the speaker purpose.  I did my own calculations using different drivers.  

This won't make a good speaker without understanding the intent and setting up DSP correctly, but maybe these parts can help you experiment.  This is meant as a hobby experiment to experience a speaker with controlled directivity.  

Pretty cool that with all the ‘open’ appearance, the radiation design is quite directed.

Fits on a Mini within mm! Uses a lot of plastic when you print it dense/solid

Don't do what I did: remember to put the seam line on the back!

Uses a Peerless HDS-P830874 woofer and Peerless TC9FD18-08-ND ‘full range’ 2.5" driver.  Base is aluminum plate in my case, and uses PVC tubing & polyfill

I am happy with the results, but recommend using with a subwoofer.  With a Linkwitz transform on the woofer the measurements show down towards 55Hz, but there's not much headroom below 80Hz for higher volume and not enough tactile bass for my preference.  Also, the 2.5" driver doesn't have the same sparkle a true tweeter does, though that's not always a bad thing.  No easy fix for that unless you throw directivity out the window and add an AMT or standard tweeter of some sort… or maybe a tweeter in a horn could be appropriate?

Attached plot shows woofer and tweeter after my quick EQ targeting flat, and combined response, about 1' in front of tweeter in the middle of a medium-sized room…  After this I'd place in room, measure at listening, and shape room target to taste
