This is my DIY speakers made from Accuton drivers. All passive crossover. Playing Dire Straits - "Where Do You Think You're Going"
Used drivers C220-11-221 (2pcs), C173-6-191E, C30-6-358. Double Transmission lines with a bit different tuning. Lower bass TL length 1,8m ratio 1:1 (port:driver). Upper 2,2m, ratio 1:3.
Made from 30 mm mdf, professional lacquer high-gloss pearl white. Soundcare superspikes.
Aperiodic vent in midrange with no high-pass filter, i.e. full-range in low frequency. Crossover L-R 12dB between mid/high. Bass low-pass 18dB.
Min impedance 3 ohm at 70Hz. Average impedance 5 ohm +-2 ohm from 50Hz to 20kHz
Runs ok on tube amp as well, but this Krell amplifier is magic!
