Klausen Audio - I've heard white van speakers that are 5x better than these - just about everything is engineered to be the cheapest and least material possible.
One cap on tweeter. Tweeters have hardly any treble, maybe the neo coin has corroded?
"Midrange" not in separate chamber, run full range.
Even worse, middle woofer with real aluminium dust cap is run full range. EW
Lower woofer seems like a passive radiator.
All in the same ported enclosure made from 1/2" crapDF
Binding posts made from some cast alloy with hardly enough material for threads or to not snap.
As for Bose 901's, they actually sound ok with the EQ.
