Tuning and Tweaks
Went with active crossover, so drivers are driven directly from amplifiers. Used digital XO and REW to determine XO points and slopes. Then replaced digital XO with Nelson Pass DIY Active Crossover.
Was not satisfied with mid bass pedestals (drivers too close to floor), so moved drivers into seperate sealed enclosure.
Electra Cable Tube Connectors for speaker inputs.
All speakers have properly loaded sorbothane with 15 to 20% deflection; Gaia III for bass speakers, carpet over cement floor.
