If one have a woodworker is possible try the Lii Audio F15($399/Pair, pair not each) 97dB/8Ω and benign impedance curve suited to OB or Bass Reflex box or the F18($540/pair), no Crossover, no Tweeter beaming, no Phase rotation, no driver sensitivity loss, no Harmonics loss, no Retail price.

Welcome!

Recommend kits for DIY loudspeaker builds.  At least you'll have a chance of hearing the finished product before building.  And you'll benefit from others experience.  Hard to compete against decades of experience and mass production setups from companies like JBL, Dynaudio, etc. that do consumer and professional gear.
