    Help bi-amping Monolith I's and replacing the bass drivers

    Jonathan, Thank you for all your advice. First the woofer. The box is two stacked rectangular volumes. The top one that obscures a portion of the panel has internal dimensions of 4.5"x23.5"x12.5" or just over 0.7 cu.ft. The bottom portion is 9"x23.5"x22.5" or just under 2.8 cu.ft. for a total...

    Help bi-amping Monolith I's and replacing the bass drivers

    I am definitely not an EE or speaker designer. The goal is to externally crossover and bi-amp the speakers. Where would I need to break into the circuits with the leads from the power amps? And what parts of this are the current crossover, that would no longer be necessary with the external one...

    Help bi-amping Monolith I's and replacing the bass drivers

    Modavid was so kind as to share his gently used Monolith III stat panels with me. The first clue that this might be a less than straightforward process was that the box label showed different SKUs for I and II's versus III's (first photo). The second photo shows the pigtail (harness) of my I's...

    Help bi-amping Monolith I's and replacing the bass drivers

    I am interested in bringing a pair of Monolith I's up to the best performance I can get, on a modest budget. I really like the idea of using the original MLs, and I am fond of their looks. Dave Gilinsky, System 38, apparently accomplished bi-amping of I's with a DriveRack 260. And JonFo and...
