JBL4410 with 2x15” infinite baffle subwoofer (using my attic as the enclosure). Technics SU-V98 powering the JBL4410s with a Precision Power car audio active crossover doing the main/sub crossover. Some Alpine amp powering the sub and a 1000W PC power supply giving 12V life to the crossover and sub amp. All fed by a Zune HD with some DIY omp-amp circuit giving a little more gain before feeding the whole system. Haven’t been able to get the magic of that Frankenstein system back since, especially with regard to bass and dynamics. Getting close with 306p and LSR310s, but I really miss that infrasonic extension.
