PS. This is always the case though. M2 for example may sound “impressive”. And that’s the goal of hifi perhaps. As a worker though, if those are the huge ones I heard awhile back, they sounded impossible to actually work on. There are some good JBLs, from way back in the day. The new ones I can’t hang with... If you/ your friends get a chance to hear some big ATC stuff, see what you think. It may not go super deep in the lows (some models) but everything else is far more natural sounding than most stuff out there.
