My home designed 6.5" monitor speakers, mainly aimed at low budgets, with incredible sound staging.
Initially started as a 10 year anniversary project to my 12" SPL subwoofers from 2007.
It is a basic 2-way enclosure for second hand jvc woofers and visaton full range speakers (frs8-4)
84DB @ 1 watt, 1 meter
45-20000hz frequency range
I used 9mm multiplex for the enclosure, and the woofer has around 8L front t-line vented enclosure tuned at ~43hz. the 3" fullrange has 2.5 liters closed to play in, i also applied 2 sheets of polyester filling for the dampening inside.
I love the sound they produce alot, they match my B&W DM603 S3 speakers very nicely.
