One big horn ribbon
+ one 8" carbon composite hi eff driver
+ 30L mixed composite cabinet (baffle plate solid wood, sides and back laminar, top/bottom NZ mdf) to kill resonance
+ all film cap and oil paper copper foil inductors
+ physically time align the drivers
+ crossover 1st order at 600hz
= 100db/w in room or 98db/2.83v/1m with a very pretty response 65hz to 25khz, 8 ohm impedanceWe will sell this as a kit hopefully with the front baffle plate as that is difficult part. Getting prices on that now.
Cabinet is 19.5" (50cm) tall x 10" (26cm) w x 14" (36cm) deep
Hoffman rusts?
