  2. Power Amp Bridging

    Two Channel Audio
    Hello Everyone; I have just finished my new (sub)woofer cabinets, (two for stereo because I need to cross over at 100 or 120 Hz), basically copying the JBL 4645c. I am using RCF LF18X401 drivers. They have a 50 mm max cone excursion but are about 3 db less efficient than the JBL woofers...
