Fascinated by the JBL Paragon speakers, set off on a path to make a miniature version as cheaply as possible. Starting with the cheapest amazon speakers possible but wanting 'point source' main drivers ended, up with DS18 speakers EXL-SQ4.0 mains and EXL-X6.4D dvc sub. Since didn't have room for 'horn woofer' had to do something different and ended up doing a 4th order bandpass with a 6' long port. 6db passive xovers. caps on mains, coils on sub, sub gets feed from each side to get a summed mono output. The port for the sub is on the back bottom of chamber, reason for the feet under it. Oh and I am not any type of woodworker I am more of a wood butcher. Anyway making sawdust without any plans I pushed forward and ended up with the following...

Summarizing that the goal of the JBL Paragon is to spread the stereo image as widely as possible and get a fair image in a wide range (might be the reason Japanese coffee houses love them). Reasoned that by the mains pointing at the apex of the curved face that the reflection from the curved surface bounces the right to the right and left to the left but the signal that passes the curve will push to the opposite side. It is true that you can walk around and get a reasonable image in a wide range but the beaming when directly in front of it would make it poor for MLP use. It has now been my desk setup for a couple years and it works decent and was a fun experiment... Pardon the dust on desk pic, live in very dusty place..
