Does anyone own or tried the MSB Sub isolators?

Hello fellow forum members. I was wondering if anyone has any experience with the MSB sub isolators. Essentially a XLR splitter for amplifier and subwoofer. I’m looking for a good solution to run XLR for my amps and subs. The y cables work but I lose resolution to my speakers compared to running the XLR into the amp without the y cable. Thanks.

Well the only observation that immediately occurs to me is that this MSB product would only be relevant to users that run their mains full-range and either use a Y connector or a preamp with parallel outputs that are not individually buffered. A proper 2 channel subwoofer crossover (Like my JL Audio CR-1) that features both high pass outs for the mains along with low pass for the subwoofer(s) would eliminate the need for this device.

actually, the problem stems from too much of the signal (strength) is absorbed/lost…though the concept and MSB engineering are good…

in the real world, it wasn’t favorable (didn’t conform to the “facts”)…
