sealed will sound much better for music and still crush for movies.
That isn't true these days and probably hasn't been for almost 20 years. Well designed ported subs sound just as good as sealed for music. The biggest difference comes with output <30Hz which then in turn depends on room size.

Rythmik is also a direct servo sub which is most definitely a clear step above normal ported subs. Non-servo are simply not fast enough to keep up musically.
Ported gives you more dbs, less tone
Ive had the SVS PB-3000, Klipsch SPL 120x2, rel t9x2 and rhythmik E15 in head to head in my theater. The difference for music between ported and non, and servo vs no servo is night and day for pure music listening paired with my Sonos Faber concerto floor standers.
The SVS created the most pressure for the room and the loudest db response under 25hz, but was the loosest for musical playback besides the Klipsch. RELs were great, but not enough umph to pressurize the room and too expensive to step up to their next tier. Ports generally created too much boom at high volume losing the clarity of the instrument (think a stand up basing going up and down scale).
Most will let you try them for a limited time and send back if unhappy. Try that first.

No.
The difference is resonant frequency tuning, and the ability of the sealed cabinet to act as a vacuum (negative pressure in the cabinet) after the cone’s excursion, to help pull it back in, and as an air piston (positive pressure) when the cone is in the innermost position to push it back out...all of which aids in less “overhang”, thus resulting in tighter low end, less smear, and better timing. It also reduces strain on an amplifier as the motor is not working as hard to start and stop, so an amplifier with a lower damping factor can be used.
